Product Overview
Introduction
We extend a warm welcome from all of us at Masonry
Fireplace Industries, LLC. (MFI), proud manufacturers of
Mason-Lite Fireplaces. Thank you for Choosing MFI.
You may have thought long and hard before you chose the
® replace which would grace your home. Rest assured that
every component of the Fireplace has been tested to ensure
long-term durability.
Product Overview
Mason-Lite Fireplaces are designed as factory-built blocks
to be assembled on-site. These ® replaces may be installed on
either combustible or non-combustible ¯ oors. In order to func-
tion, the system requires a 10 B-vent chimney.
The main components of the Mason-Lite Fireplace are:
Mason-Lite Firebox and Smoke Dome
Gas burner, logs and control system
B-vent
Careful step-by-step instructions for each phase of the in-
stallation procedure will be given for the Mason-Lite ® replace.
Those instructions generally fall into the following categories:
Spacing and clearance as it relates to combustible materials
Familiarity of installation for all components
The strength of the ¯ oor on which it rests
Chimney system measurements
Set up and use of the gas burner system.
Choice of materials and craftsmanship in ® replace and hearth
® nishing.

WARNING! Under no circumstances should you allow children
to remain unattended while a ® re is burning in the ® replace! Be
sure to keep all objects furniture, drapes, rugs, etc. at least
48 (48 inches) away from the opening of the ® replace!
Attention: You may need a residential building permit to install
a Mason-Lite Fireplace. Consult local jurisdictions before you
get started!
The MASON-LITE gas ® replace is not designed to serve as a
primary heat source, rather, the ® replace was expressly created
as a supplemental source of heat. This unit is designed for use
with the provided gas burner and approved logs only.
Testing and listing for the MASON-LITE gas ® replace has been
undertaken by PFS Test Laboratories, Inc. to ANSI Z21.50.
Under no circumstances should the MASON-LITE gas
® replace be considered for other than in-residence buildings of
conventional construction.
These components make up the MASON-LITE gas ® replace
and in the following pages, you will learn how they work
together to create an exceptional unit that will give years of
service and pleasure!

Required Gas Pressure
The minimum inlet gas supply pressure for the purpose of
input adjustment is 5 of water column (w.c.) for natural gas.
The maximum inlet gas supply pressure is 10.5 w.c. for
natural gas. The minimum inlet gas supply pressure for the
purpose of input adjustment is 11 of water column (w.c.) for
propane gas. The maximum inlet gas supply pressure is 13
w.c. for propane gas.
Testing the Gas Supply System
The gas ® replace and its required individual shut-off valve
must be disconnected from the gas supply piping system
while performing any tests of the piping system at pressures in
excess of 1/2 psig.
The gas ® replace must be isolated from the gas supply
piping system by closing its individual manual shut-off valve
during any pressure testing of the gas supply piping system at
test pressures equal to or less than 1/2 psig.
This is accomplished by closing the gas supply line valve
required by NFPA 54.
A ® replace screen must be replaced after service and be
in place when the appliance is in operation and, unless other
provisions are provided, the screen shall have an opening for
introduction of combustion air.
When glass ® replace doors are used, operate the gas
® replace with the doors open. Use only doors rated for this
appliance.
Important
To comply with building code acceptances, and for safe
operation and proper performance of this ® replace, use ONLY
MASON-LITE parts and accessories.
Use of other controls, parts, and accessories which are not
designed for use with MASON-LITE gas ® replaces is prohibited
and will void all warranties, certi® cations, listings, and building
code approvals, and may cause property damage, personal
injury, or loss of life.
The burner included with this gas ® replace is non-convertible
and only meant to be used with the gas listed on the rating
plate.

Clearance to CombustiblesClearance to Combustibles
The distance to be maintained from the surfaces of the
® replace to combustibles must be observed. Below is a list of
the most common combustible materials to name a few:
Drywall Wood ¯ ooring Plywood
Sub-¯ ooring Wood Framing Particle board
Mill board Plywood paneling
Maintain the following minimum clearances:
Unit front, sides, rear 0 (0 mm)
Combustible ¯ oor 0 (0 mm)
Sheathing or trim to opening sides 8(203 mm)
Combustible sheathing above opening top 8(203 mm)
Mantel above opening 12 (305 mm)
Opening to side wall 20 (508 mm)
Insulation from ® rebox 0 (0 mm)
Due to high temperatures, never install this ® replace in a
recreational vehicle, in high traf® c areas, drafty areas, or
where curtains, furniture, clothing, or other ¯ ammable objects
are less than 36 from the front or side and 42 from the top of
the ® replace.
CAUTION: This gas ® replace attains high temperatures. Keep
children and adults away from hot surfaces to avoid ignition of
clothing and/or burns. Even after the ® replace is shutdown it
will remain hot for a time afterward. Allow the surface to cool
before touching it.
Carefully supervise young children when they are in the room
with the ® replace.
All ® replace openings for both combustion air and exhaust
must remain open and unobstructed at all times when the
® replace is in operation.
The MASON-LITE ® replace has been designed, tested
and approved for zero clearance to combustible ¯ oors.
Be certain that the MASON-LITE ® replace is installed with
the ® nished ® re brick ¯ oor of the ® replace so that it is at least
4-1/2 (four and a half inches) above the combustible ¯ oor
system.
Warning to the structural engineer and/or building contractor:
It is your responsibility to be certain that the ® replace can be
properly supported by the combustible ¯ oor system on which
the ® replace will rest. Be advised that this engineering equation
will be in addition to any live or dead weights that the ¯ oor has
to carry.
Mason-Lite Fireplace & Chimney Systems
Before Getting Started
Even if you consider yourself an expert in the ® eld of
® replace installation, we at Masonry Fireplace Industries
caution you to take the time to totally familiarize yourself with
the instructions to follow.
We can assure you that there will be information that will
make the installation go smoother and, above all, safer, for
everyone concerned. At the least, reading these procedures will
save you time and, at the most, it will prevent any malfunction
that could result in property damage or serious injury.
Do not start the installation until you have checked out all
the local, regional, state and national rulings, laws and codes
as they apply to ® replaces and ® replace installations. Every
community is different so do not assume that because you
know the requirements for one locality, it will be the same in
the next. Avoid bureaucratic hassles and do your homework
WELL BEFORE you start your project!
The MASON-LITE gas ® replace is designed to be
installed with a B-vent metal chimney system, UL 103
chimney. Such chimney systems are acceptable where
any traditional masonry ® replace has been speci® ed.
Note that the chimney system must always vent to the
outside of the building.
This Mason-Lite ® replace is intended as a supplemental heat
source only. It is not intended as a primary heat source.
It is the responsibility of the contractor installer (not the
manufacturer) to ensure that adequate combustion air is
provided for proper function of this ® replace. Fireplaces
take up a large volume of replacement air from outside the
house and if the house is of airtight construction, smoke
spillage may occur if proper draft is not achieved.
There are many conditions beyond a manufacturers
control when it comes to the operation of the ® replace.
The manufacturer cannot be responsible for smoke free
operation, nor can the manufacturer take on the responsibility
for problems with surrounding construction; chimneys that
have not been built at the right heights; system drafts caused
by faulty mechanical systems; adverse weather conditions
or any other inclement environmental situations over which
the manufacturer has no control.
Inspect all ® replace & chimney components for evidence
of damage prior to starting installation. Consult your local
distributor for replacement parts if necessary.
Under no circumstances should you make any adjustments
or modi® cations to the chimney system during the
installation procedure. If you do, you are not only liable
for negating the warranty, but you could very well cause a
serious malfunction of the ® replace. You must follow these
chimney instructions.
Chimney System Heights
When installed, the maximum overall height of the Fireplace is
40-0 (forty feet). The minimum installed height of the
completed ® replace is 14 0 (fourteen feet), given that the
chimney is straight. If the chimney includes one or more offset
sections, the measurement is 17 0 (seventeen feet).

Supporting Floor Systems
It is the ultimate responsibility of the installer to ensure that
proper concrete slab supports are used.
WARNING to the licensed design professional and/or building
contractor: It is your responsibility to be certain that the Mason-
Lite can be properly supported by the combustible ¯ oor system
on which the ® replace will rest.
For ® replace support foundations installed on concrete refer to
Appendix I and II (pages 31 & 32) for speci® c instructions.
Rebar locations
Lay-out the position of the ® replace and drill holes where
the rebar will be located. Secure the #3 rebar 4 inches into
the concrete foundation with ITW Epoxy or Simpson Epoxy.
Follow manufacturers instructions for installation of rebar into
slab.
Wood Floor
Anchorage of ® replace to wood ¯ oor construction is required.
Refer to Figure 9 for anchorage dimensions. Four anchors are
required to attach to the sub-¯ ooring framing.
Crawl Space or Upper Floor:
For installation of ® rebox over combustible crawl spaces or
upper ¯ oors, anchorage of the ® rebox is required. Illustrations
of examples of possible anchorage methods are shown in
Figures 6 thru 8 depending upon the type of ¯ oor framing. Final
method of anchorage is to be determined by licensed design
professional.
For conventional framing, where the ¯ oor joists are parallel
with the sides of the ® rebox, the addition of ¯ oor joists to align
with the anchor brackets allows the brackets to be directly
connected to the ¯ oor joists.
Note that additional ¯ oor joists may be required to support
the weight of the ® rebox and chimney. Where the ¯ oor joists
run parallel to the front of the ® rebox, anchorage can be
accomplished in like manner as shown in Figure 6 using
blocking between the ¯ oor joist.
For ¯ oors supported by I-Joists, the method of anchorage is
illustrated in Figures 7 and 8. Figure 11 illustrates the general
arrangement of anchorage to ¯ oor framing.
It is important to take into consideration that the load for
the Mason-Lite Fireplace must be considered as additional
dead load that will have to be supported by the ¯ oor framing.
Additional ¯ oor joists or I-joists may be required as determined
by the licensed design professional.
The dead weights for the ® replace are noted in Table I. It is
the task and responsibility of the general contractor/installer
to see that the proper reinforcement for weight loads are
made by a licensed design professional prior to the ® replace
installation.
As stated above, it is desirable to place additional framing
for alignment of anchor rods. Refer to Figure 9 for anchor rod
locations.

What You Will Need
You will ® nd that the MASON-LITE Fireplace is designed to be
completely assembled on-site, consisting of interlocking precast
parts. The parts of the ® replace are made of Mason-Lites
incredibly strong blend of specialty cement and a light weight
aggregate.
IMPORTANT! When applying mortar, it is imperative that the
concrete blocks be maintained moist (not soaking) so they dont
absorb the water out of the mortar and cause adhesion to fail.
Frequently run a damp sponge to the parts before mortar is
applied!
The installation of an anchor plate/damper is required but not
supplied. You may purchase it from any chimney manufacturer
or MFI. Also, an optional combustion air inlet MFP4-AK can be
obtained from MFI.
Refractory Firebrick Liners also need to be installed. These
should be a minimum of 1-1/8 (one and one-eight inches) thick.
The liner will be applied within the walls and hearth area of the
® rebox. These are available from MFI. See page 27.
Tools needed for installations:

SURFACE CRACKS - The MASON-LITE FIRE-PLACES are
manufactured using high quality materials. During the
drying process, surface cracking may occur. These small
cracks (under 1/16” will not affect the fi replace safety or
performance). During the assembly process, fi ll surface
cracks with thin-set mortar and brush when drying for a
smooth surface fi nish.
Field Assembly Procedures
Mixing the MASON-LITE mortar The mortar comes
premixed and should be dry. Be sure to use clean water and
work it up into a mixture that is pasty but not lumpy. If its too
thin and the surfaces dont stay moist, the components will
not adhere. Load the mixture into a standard grout bag.
Apply about ½ (one-half inch) thread of mortar. The mortar
bead should be approximately ½ (one-half inch) away from
all edges. The mortar has a considerable amount of holding
power so do not overload the components with too much
mortar. Keep the components moist at all times!
Some mortar will ooze out when placing components
together, this is normal. Wipe excess away with a trowel. Do
not cover component surfaces completely with mortar. Do
not apply the mortar in thick bands even if the component
you are working with is larger than the rest. You will want to
apply stripes of mortar in these situations.
Make sure components are level. Its extremely important
that you pay careful attention to how you are assembling
the Mason-Lite Fireplace since every component builds on
the next. If you have to make any kind of an adjustment,
do not try to do it by loading an opening with mortar, this
will only result in a ® replace that will not be plumb or level.
Use wood shims instead. You will fi nd these small wood
shims supplied with the Mason-Lite Fireplace and
you can nudge them in between openings to achieve the
precision you need in making component adjustments.
Once you have removed any shims, you will want to cover
any gaps that may have resulted with the mortar.

Fireplace Assembly ProceduresFireplace Assembly Procedures
Place the Mason-Lite ® replace hearth on the ¯ oor where the
® replace is to be installed. For concrete slabs, supporting
¯ oor needs to be rated at ASTM 90.
Draw an outline of the hearth area based on the dimensions
shown in Figure 12. Position Hearth slabs and mark rebar
center locations. Drill 4 inches into concrete slab and secure
the 8 pieces of 12 inch rebar with epoxy. For other than
concrete slabs, draw an outline of the hearth area based on
the dimensions in Figure 5 taking special consideration on
the position of where the all-thread studs will be located in
relation to the anchoring locations. All-thread rods should

You also have the option to have custom ® rebrick installed,
but it must be at least 1-1/8 thick.
Before you install the lining, you will need to drill all the
required gas and electrical line feeds and the combustion air
supply access holes.

building code safety clearances, per units that have
openings of 6 sq. ft. (six square feet) or greater. You must
keep combustibles such as trim 8 away from the ® rebox
opening (for mantel clearances, see Figure 26).

Mantel and side clearances
Attention: The manufacturer suggests that when building
out a ® replace, that the owner and installer opt for complete
safety. MFI, therefore, advises that combustible mantel
shelves feature clearances that are more than the 12
(twelve inch) minimum equal to the projection of the shelf.
As a guide, ® gure that a 10 (ten inch) wide shelf should be
20 (twenty inches) above the ® replace opening.
Walls That Adjoin Safety codes and all practical outlooks
insist that your ® replace cannot be installed closer than 2 ft.
(two feet) to any walls in the room the ® replace is housed in
or to any walls of adjoining rooms.

Caution in Regards to Combustibles If any part of the
® replace or objects in the room (curtains, rugs, paint,
cushions, etc.) start to show warping or discoloration due to
heat from the ® replace, it is time to take immediate action.
Each installation requires a different set of circumstances
to deal with the problem, but one thing is certain: do not
use the ® replace until you have ® gured out how to address
the problem. You are facing a potential ® re hazard. The
manufacturer of the MASON-LITE gas ® replace cannot be
responsible for the make-up of material on the exterior of the
® replace you have chosen, nor can MFI be held responsible
for the materials in a room that may be responding negatively
to heat. However, in almost all cases, there is a solution to
the problem, either by making adjustments to air¯ ow or the
room itself.
Installing Outside Air
Be mindful that outside, fresh air is not required for the
operation of the Mason-Lite Fireplace. However, local
building codes may require combustion air and it is an
excellent choice in some situations, especially in weather
conditions where homes are very well insulated and
tightly sealed. Check local building codes for speci® c
requirements.
Install Outside Air Kit - MFP4-AK into the Mason-Lite
Firebox either through the side wall opening provided. The
tubing that goes out of the ® rebox wall must feed into a
¯ exible metal conduit as the source for outside combustible
air. It can go straight out through an outside wall or into a
ventilated crawl space. If crawl space is used, check codes
for proper termination.
Be sure that you carefully check the source of the outside
air before you choose the site for your air intake. You dont
want a place where snow will collect, where bushes or trees
will be growing or a location that is too close to any other
structure.
The suggested maximum height for the air intake tubing
is 50 ft. (® fty feet) above the hearth. That height is if the
intake ® nishes off at a minimum of 3 ft. (three feet) below
the chimney cap level.
Install a screened termination cap to keep out animals.
Mason-Lite Chimney Systems
Overview
This Mason-Lite gas ® replace may be installed with an
approved 10 B-vent chimney system. A metal chimney adapter
is required to attach the chimney to the top of the ® rebox. This
can be purchased from FMI: part number MFP-DD.
Installers are cautioned to put the chimney system together
exactly as instructed and shown in chimney manufacturers
guide. Any variations may have serious consequences resulting
in an accident or malfunction. If instructions are not followed,
the warranty on the product will become null and void.
3.
1.
2.
3.
4.
5.
Note that the most important aspect of the installation is the
maintenance of minimum required clearances to combustible
materials. Those speci® c installation requirements must
be followed with great precision as you are dealing with the
potential of ® re hazard if the correct combustible limit is not met
and maintained. When you look at the drawings provided in this
section, you will see that actual installations may vary due to
individual design preferences. That is to be expected.
Design and framing speci® cs may vary from the drawing
to installationy. Clearances to combustibles is a stringent
requirement.
WARNING:
If you do not use chimney manufacturers parts and/or if you
do not follow exact instructions for installation of chimney
components, you may be responsible for ® replace malfunction,
an accident or a ® re hazard.
Attention: Be advised that your choice of Chimney System
meets the following standards and requirements:
Designed for installation in accordance with National Fire
Protection Standard
Meets requirements of NFPA 211
Designed in accordance with BOCA Basic National Codes
Meets Uniform Building Codes.
General Chimney Requirements for Height and Clearance
When installed, the maximum overall height of the chimney
system from bottom of ® replace to the top/termination chimney
is 40 feet. The minimum installed height of the completed
Chimney System is 14 feet with a straight ¯ ue stack, 17 feet if
the chimney includes one or two offset sections.
Throughout the length of the chimney along the outer
periphery of the ¯ ue you must have at least 1 (one inch) of
clearance all around the circumference. When the chimney is
passing through a living space, it must be completely closed off.
A live chimney is never allowed to be within reach of humans;
the chimney must be completely designed to be hidden from
view and protected, away from human interaction.
Note that it is acceptable for the chimneys ® restop space and
roof ¯ ashing to come in direct contact with common construction
materials, such as drywall, ¯ ooring, paneling, plywood, millboard,
particle board and a variety of normal framing materials. Always
follow the speci® c installation requirements of your selected
chimney manufacturer.
Determining Finished Height for Fireplace
Overview
Figuring out the exact height of the Mason-Lite Fireplace you
are about to install is relatively easy if you follow a few simple
steps. It is a matter of determining the number of chimney
sections and the chimney components that will be required for
the installation. Bear in mind that the minimum height of the
MASON-LITE once installed is 140 (fourteen feet) and that it
●
●
●
●
15
is higher if offsets are used. Here is how to calculate the height
of the completed ® replace:
First, ascertain the height of the chimney. This includes the
distance from the very top of the smoke dome to where the
top of the ¯ ue ends. That is where the smoke leaves the
¯ ue.
Aside from the chimney sections, include all the components
that you will be using in your installation - anchor plate
damper, ® restop spacers, stabilizers, and offsets.
Create a Component Height Chart by measuring each
component and completing the following:
Anchor Plate = 4
Firestop Spacers = _ _ _ _ _ _
Support box = _ _ _ _ _ _
Stabilizers = _ _ _ _ _ _
Offsets = _ _ _ _ _ _
Pipe Sections = _ _ _ _ _ _
(Stabilizer Must be present on vertical chimneys every
30 feet and on offset chimneys every 10 feet.)
Take the total height of every component that will be included
in your installation and then subtract that from the desired
total height you wish the ® nished ® replace system to be.
You will need to refer to the chimney manufacturers
information in order to ® gure out the available lengths and
the quantity of the sections that you will need.
The Special Case of Offset Installation
Overview
Special, detailed installation instructions must be given for the
proper handling of offsetting for the chimney system. Maximum
offset is 30 degrees off of vertical and there should be no
more than one offset sequence per chimney system. Under no
circumstances should two offsets be attached to comprise a
60 degree offset con® guration. Always maintain at least 2 (two
inches) of clearance around all offset installation for air space
and necessary clearance from combustibles.
Working with Floors and Ceilings
It is quite probable that when your installation must pass through
a ¯ oor or ceiling, you will have to opt for a 30 degree angle in
which case you are advised to use a ® restop spacer. Should
the length of the chimney below the ¯ oor or ceiling be less than
10 (ten feet), support the chimney at the juncture of the ¯ oor/
ceiling with a stabilizer. As in all phases of chimney component
installation, you will want to be sure you are making allowances
at every juncture for the 2 (two inch) clearance space from
combustibles.

Background Information on Offset Installation
When obstructions are present, it will be necessary to
offset sections of the chimney using the 30 degree offset
component and, for every offset component, two elbow
components.
One elbow begins the installation procedure and the second
elbow is used to ® nish off each section. In all likelihood, a 30
degree offset elbow will probably be the ® rst hardware used off
the top of the anchor plate damper.
Note: Under no circumstances should you use an offset
elbow in place of a return elbow. They have distinct purposes
in the con® guration of the offset installation and they cannot
be interchanged, part for part.
Depending on the con® guration you are contending with,
you may either attach the elbows and offset piping together
or you may need to insert sections of the vertical chimney.
Whatever the scenario, you cannot allow sections of the
chimney to measure more than 20 (twenty feet) between
the elbows.
Assuming you have sections of vertical pipe that are more
than 10 (ten feet) measuring between elbows, you must
insert at midpoint a chimney stabilizer. When installing
the stabilizer, pull out the support straps with a good amount
of tension and hammer to the frame.
If your offset sections go over 6 (six feet) in length, you
will need to give added support using a sheet metal screw
a # 8 x ½ is recommended. The screw will be fastened
underneath the joint.
To ensure a tight ® t for the screw, drill a hole that is 1/8
(one-eighth inch) in diameter right at the chimney joints
underside. Be sure that you position the drill at the very
center of where the joint overlaps. Be very careful not to
drill through the inner casting; drill only through the outer
chimney.
Installing Vent Plate and Chimney System
Before installing your B-Vent to the Mason-Lite Firebox you
must install a steel vent plate. The vent plate mudt be installed
in the vertical (open) position on the outside of the vent pipe
and is designed to close-off the chimney in the event the pipe
is removed or fails, thus alerting the operator of a problem.
Next, attach the masonry anchor plate (supplied). The
anchor plate is pre-drilled with holes for four (4) cement wedge-
anchors.
Place the plate and mark the top of the ® rebox. Then remove
the plate to carefully pre-drill holes for the wedge anchors.
Using the supplied vent plate, apply a 1/4 (one quarter
inch) bead of gasket cement around the base damper lead
pipe. Apply ceramic rope gasket on to the gasket cement.
Apply balance of gasket cement in a 1/4 (one quarter
inch) bead on top of smoke dome top approx. 3 (3 inches)
outside of outlet hole. Install damper on top of unit pressing
damper into cement. Attach using four (4) #8 cement
wedge-anchors.

A B-type venting system must be connected to the
appliance for venting to outside of building. The following
section is provided as a guide to a standard B-type vent
installation.
Standing codes requirements concerning B-type vent
installations may vary within your state, province or local codes
jurisdiction. Therefore, it is recommended that you check with
your local building codes for speci® c requirements or in absence
of local codes, follow Section 7.0 of the current National Fuel
Gas Code ANSI Z223.1/NFPA 54 for Category I systems using
double wall B-1 vent pipe.
This gas appliance must be vented to the outdoors only
and may not be terminated into an attic space or into a chimney
¯ ue servicing a solid fuel burning appliance.
This appliance may be vented through a manufactured
chimney system or a masonry chimney using a B-vent adapter
or a chimney liner system if the system is listed, inspected
and approved by local codes and/or building authorities. The
examples shown in Fig. 2 are typical of most B-vent installations
and codes practices.
Example 1: Shows the minimum allowable system height and
lateral offset for an inclination of 60° or greater.
Code speci® es that offsets of 60° or greater are considered
horizontal and must follow the 75% rule for lateral to total
vertical system height.
Codes also allows only one offset in the total system when
at 60° or greater.
The total vertical height in this example represents the
minimum height of 8 ft. and therefore the allowable lateral is 6
ft. when the 75% rule applies.
If the lateral length must exceed 75% then the system must
be sized in accordance with the Category I venting tables.
Example 2: Shows a multiple offset each at a 45° inclination.
Multiple offsets are permitted if they do not exceed a 45°
inclination. The total lengths of the two offsets are not required
to meet the 75% allowable rule.
Example 3: Shows a single offset at 45° of inclination and
therefore the lateral length at 10 ft. of offset does not have to
meet the 75% rule.
In each case the offsets must be supported and ® restops
must be positioned wherever the vent must pass through a
sub-¯ oor, ceiling joist or an attic overhang.
The vent pipe must terminate vertically into a listed type
vent cap and extend a suf® cient height through an approved
roof ¯ ashing, roof jack or a roof thimble. At all points the listed
clearances must be maintained.
Vent terminations must be located in accordance with
height and proximity rules of NFPA No. 54.
These rules apply to vents at 12 diameter or less and
require a minimum height in accordance with the roof pitch and
a minimum of 8 ft. distance from a vertical wall or obstruction
(see Fig. 3).
If venting horizontally through a side wall becomes
necessary, a listed thimble approved for use with B-type vent
must be used. Check with your local codes before venting
through a side wall.
Some codes areas allow the use of existing B-type vent
systems if the system is at or above the recommended diameter
of the ¯ ue.
The ¯ ue connection must be made using listed B-type
connectors and the existing system must be code inspected
for damage and proper installation.
It is not recommended that this appliance be common
vented with an existing gas burning appliance. However, if it
becomes necessary to common vent this appliance, the venting
system must be sized and con® gured in accordance with the
common venting guides Appendix G of the current National
Fuel Gas Code NFPA No. 54/ANSI Z223.1.
Note: Before connecting this appliance to an existing vent
system or a common venting system, consult with your local
architect, planner, or building of® cial.
Venting Installation
Figure 2
17
Specifying Chim ney HeightsSpecifying Chimney Heights
If the horizontal distance from the mid-point of the chimney
to the peak of the roof ridge is less than 10 feet, the top of the
chimney must be at least 2 feet above the roof ridge. This is
called the 2 foot in 10 foot rule.
If the horizontal distance from the chimneys center
measured across to the ridge of the roof is more than 10 feet,
the top of the chimney still needs to be at least 2 feet above a
point measured from a distance of 10 feet horizontally along
the roof.
Figure 3
Though there are many con® gurations in meeting these
requirements, chimney height cannot be less than 3 feet above
the roof at the edge of the chimney.
If the roof is ¯ at, the chimney must extend no less than 3
feet from where it intersects the roof. If the chimney is entering
the roof at an angle, measure the shorter angle where the
chimney intersects the roof which should be at least 3 feet.
Note: The previous guidelines do not take into consideration
outside conditions which may require a higher chimney due
to foliage, other buildings, power lines and weather conditions
in your area. Follow the chimney manufacturers installation
guide for further information.
Chimney Termination Units
You will be installing at or possibly near the top of the
chimney chase ¯ ashing. A top termination unit is the essential
piece of equipment in keeping sparks out of the atmosphere.
Before installing this important piece of equipment, you will have
to make a judgment call as to whether or not the termination
unit like all the other exterior exposed chimney components,
for that matter should be painted in order to protect it/them
from rusting and weathering. Particularly if you are installing
the ® replace and chimney near water or in a high humidity area,
the manufacturer recommends a top quality, rust-proof paint
especially formulated for metal. Follow the paint manufacturers
directions, applying the paint well before you are scheduled to
install the round top termination unit or any of the ¯ ashings or
¯ ues that will be exposed to outside weather conditions.
Venting terminals shall not be recessed into walls or siding.
This appliance, when installed, must be electrically grounded
in accordance with local codes and in the absence of local
codes, with the National Electrical Code, ANSI NFPA 70, or the
Canadian Electrical Code, CSA C22.1.
Important Pre-installation Information
Before you begin, review the information and safeguards
below regarding the installation and operation of the gas
Fireplace.
This fi replace may only be connected to the gas supply
listed on the label. Never use propane gas in a gas ® replace
designed for natural gas or natural gas in a gas ® replace
designed for use with propane gas.
The gas ® replace must be installed by an MFI Certi® ed or
other quali® ed professional installer. The installation, including
provisions for combustion and ventilation air, must conform

Owner’s Operation & Precautions
Installers of the Mason-Lite are urged to call the attention of
® replace owners to the following precautions.
The installer should hand-deliver this owners manual to the
owner or leave behind with the unit after it the installation is
complete.
Warning: Use only the included ® replace grate or manufacturer
approved replacement.
Warning: Do not attempt to operate your ® replace without a ® re
safety screen installed.
19
CAUTION: Use only the logs that come with this gas ® replace.
The manufacturer cautions against using chemical chimney
cleaners. Never burn solid fuel in this fi replace under any
circumstance.
First Lighting of the Mason-Lite After construction is
completed, all elements of the ® replace and chimney
system must be completely dry. This means that the unit
must stand without any ® ring for a minimum of 28 days.
Only after that period of time can a ® rst lighting take place.
Do not let the ® re burn for more than one hour. After this ® rst
lighting when the ® replace has started to cure Do not set
another fi re for at least 24 hours.
Second Lighting With the second lighting you can let the
® re burn two hours no more.
After First and Second Lighting When the ® replace has
been properly cured with careful maiden ® rings, you will
be able to run the burner for as long as you like.
Attaching the Burner and the Grate
Unpack the burner assembly and place the rear legs of
the burner into the brackets in the back of the ® rebox (see
Figure 23).
Thread the pilot lines from the burner pilot assembly and
through the hole in the lower side of the ® rewall to the valve/
control box assembly and attach to the valve.
Connect the supplied ¯ ex connector from the output of the
valve, through the hole and to the burner.
Connect the second ¯ ex connector from the input of the
valve to the gas stub down stream from the required
manual shut-off valve.
Note: The required 1/8 NPT up stream pressure tap is built
into the valve (Figure 33).
CAUTION: CHECK ALL CONNECTIONS FOR GAS LEAKS
USING A HALF-AND-HALF SOAPY WATER SOLUTION.
IF A LEAK IS DETECTED TIGHTEN CONNECTIONS AND
TEST AGAIN.
NEVER USE AN OPEN FLAME TO CHECK FOR GAS
LEAKS.
Insert a one-way screw into the hole in the front of each
bracket and tighten with a long (min. 12) screw driver until
contact is made with the grate leg and the grate is permanently
locked in place (see Figure 23).
IMPORTANT: Once installed the burner cannot be
removed.
Fill in the holes you have drilled around the gas piping with
the regular MASON-LITE mortar.

TO LIGHT THE FIREPLACE WITH THE WALL
SWITCH
Move the ON-REMOTE-OFF wall switch to the ON position
(Figure 41). This transmits a rapid series of sparks at the pilot
head and will ignite the gas.
TO SHUT DOWN THE GAS FIREPLACE USING THE WALL
SWITCH
Move the switch to the OFF position (Figure 41). The gas ¯ ow
will cease, and all ¯ ames (main burner and pilot) will go out (see
important note below).
OPERATING THE BURNER USING THE REMOTE
Move the wall switch to the REMOTE position and follow the
instructions included in the remote kit for lighting and shutting
down the attached burner.
IMPORTANT: Do not allow the ® replace opening to be
blocked in any way while operating the ® replace. The
® replace may be operated with a Mason-Lite screen installed
and drawn.OUT INPILOTINFigure 41

MAINTAINING THE PILOT
Your gas ® replace is equipped with a safety pilot that will shut
off the gas supply in case the pilot is not burning or functioning
properly. Regularly verify that the pilot is adjusted properly with
the pilot ¯ ame hitting the electrodes as shown in Figure 42. If the
pilot will not stay lit, call your local gas utility or gas supplier.
TO CHECK UPSTREAM GAS PRESSURE
Unscrew the four (4) screws above and below the control panel
face, then pull the control panel out far enough to expose the
test ports on the valve (Figure 41). Unscrew the port marked IN
part way and test.
CAUTION: Do not kink the ¯ ex connectors coming from the
valve while accessing it.
Note: Pilot ¯ ame should encircle top of electrodes.
See instructions cover for example of proper main burner ¯ ame
pattern.
FOR YOUR SAFETY, READ BEFORE LIGHTING
Do not use this gas ® replace if any part has been underwater. Immediately call for a quali® ed professional service technician to
inspect the ® replace and to replace any part of the control system and any gas control which has been under water.
The Mason-lite burner system has a pilot which can be lit by hand using a match or lighter. When lighting the pilot, follow these
instructions exactly.
BEFORE LIGHTING, smell all around the burner area for gas. Be sure to smell next to the ¯ oor as some gas is heavier than air
and will settle on the ¯ oor. IF YOU SMELL GAS, FOLLOW THE INSTRUCTIONS ON THE COVER (P. 1).
Lighting and Operating Instructions
WARNING: If you do not follow these instructions exactly, a ® re or explosion may result causing property
damage, personal injury or loss of life.

Maintenance
Once installed and operating properly, the Mason-lite gas
® replace requires very little maintenance.
You should inspect the ® replace, chimney, burner and control
annually for the following:
Excessive Sooting - Some sooting of the logs is normal
and adds to the natural appearance of burned wood. If soot
accumulates, you may brush the soot off with a stiff brush.
Logs may also be cleaned by allowing them to heat up, then
spraying them with water where soot has accumulated.
Debris around the control - Inspect the control and pilot to
be sure it is free of any dirt or debris.
Insects and burner blockage - Check the burner ports
and the air-mixer, if present, to make sure they are free
from debris. Blocked burner ports and ori® ces may
result in poor ¯ ame distribution or ¯ ame at air mixer (if
equipped). Reference SOLUTION, to symptoms 2-4, of
Troubleshooting.
