They do still agree. With this said, you can safely and within Code, upsize the AHU -1 from a 15HP motor to a 20 HP motor. The breaker in MCC -EM that currently feeds the motor starter will need to be upsized from a 3P -30A breaker to a 3P -50A breaker. With this change the wire between the MCC and the air handling unit will need to be upsized from what it is to #8 wire. It should still fit in the existing conduit. With this addition, the existing service that feeds MCC -EM is still within the 600A rating of the main breaker. With this addition, the system is still within NEC requirements. ENGINEERED AIR L HEDirect fired Make U p Air Heaters f Attachmen WHAT' Direct fired air heating occurs when the combustion of fuel takes place directly in the supply air stream. The products of combustion entrained in. the air stream represent a small portion (less than 0.02%) of the total volume of supp!y air and as such the air is completely safe for supply to occupied spaces. WHERE: Make up air is required to replace large or continuous quantities of exhaust air, where problems may occur due to a negative pressure in the space. Make up air applications include; kitchens, The proper application of make up air prevents excessive infiltration (drafts) and allows vented equipment and exhaust systeins to function properly, energy costs for make up air may be significant and therefore the most efficient system should be selected to provide it. Direct fired make up air treaters may I>e considered to be 100% ef-icient, because no heat is vented to the atmosphere. The theoretical 100% efficiency should be reduced to 92% due to water vapour being formed as a natural product of co--i-ibustion, Only 92% of -tie input is available for sensible heating, with the other 8% increasing the relative humidity of the air since the vapour formed cannot be condensed (see Table #I). Direct find heaters can provide substantial savings over indirect fired heaters (indirect fired heaters typically average up to 84'% efficiency. for example Eng A DJ /DJE series). It should be noted that in Canada direct fired heaters applied in occupied areas are limited to 75`F (24 "C) maximum discharge temperat °.:re and must use 100/0 outside air.

Control side 42 "(,1057 mm) Opposite side 1 "(25mm) Top 1 "(25nhr�h) Bottom 0 "(0rhhnh) INTERLOCKING -Where a direct fired make up air heater is installed in conjunction tenth a mechanical exhaust system, it is essential that the air hewer be interlocked with the exhaust system. - LIthoLrgh the exhaust system may operate without the make up air heater, the make up air heater should not be able to operate without the exhaust syster-1 functioning. The interlocK may be electrical (from the exhaust fan starter) or from an air flow proving switch in the exhaust system. WotE that some codes and authorities require the air flow proving switch and will not accept an electrical interlock. Where two exhaust systems are being satisfied by one dual capacity unit, additional interlocks will be required. The National Fuel Code determines field interlocking requirements for the USA. CSA 8149 natural gas and propane installation cone determines interlocking requirements for Canada, POWER SUPPLY - The most corllrnon power supply is a 3 phase 60 l,tz sozuce. Single phase andlor 50 Hz units are also available. Control circuit power requires a 120Vl1,160 Hz circuit or a unit mounted control transformer. GAS SUPPLY - The H' series direct fired make up air heaters are available to fire an "' or 14" w,c, riatural gas or 11" w.c, propane at unit inlet. Use of 14" w.c. natLiral gas is recommended where available. ':Abere higher pressure natural gas is desirable. high pressure manifolds up to 5 PSI or a pounds to inches regu'ator nyc'Unied externally are required, All vented valves and eaulators on indoor units must be piped to atmosphere. The HE series may be selected t0 bu'n other fuels. such as butane Or manufactured gas (Cortaci —Engineered Air Sales Office for assistance) INLET AIR SUPPLY - AlthaLigh the burner is of a safe comprehensive design, there are a number of conditions wtlicll should be considered regarding air supply to the unit, (1) The air flow ai the burner must be substantially laminar. Otherwise, poor combustion, an uneven flame and air temperature will result. Abrupt changes in direction of air flow or large obstructions immediately upstream of the burner should be avoided. ;2) USA standards. industrial and process applications allow the direct -1red burner to be used to heat recirculated air, Canadian standards do not a)low recirculated air for direct fired heaters in occupied spaces, (3) If dusty outdoor atmospheres prevait, a ifter bank should be employed in the air inlet hood, unit or duct system. (4) Tile outside air intake should not be located near exhaust equipment such as exhaust grilles, high humidity vents, plumbing vents or chimneys.

Kuck Mechanical of Loveland, CO is under contract to perform the installation, and the unit should be arriving on site on or around November 10, 2012. It is imperative to the operation of the plant that this project be completed by November 16. In addition, as a public entity, ERWSD respectfully requests a waiver of permit and plan review fees.
