Control ceiling plenum inlet damper with duct mounted discharge thermostat. • Install line size electrically operated solenoid valve in boiler return water piping at boilers 5-1 and &2. Provide and install Tekm2r 262 Lead-Lag boiler staging controller (or equal) to alternate boiler operation as required to provide heat for space and domestic water temperatures. Arrange boiler controls and piping to shut- off boiler return valve whenever boiler is not calling for heat. Arrange to allow homeowner selection of lead and lag boiler/pump combination. We recommend that the following general service operations be conducted to insure proper installation and operation of the existing mechanical systems: ■ Adjust factory provided controls on boilers &1 and 0-2 to prevent operation of domestic hot water heating circulating pumps (P-6) when building heat is not required but domeWm,hot water heater is calling for hniler heat. • Program domestic hot water circulating pumps for continuous 24/7 operation. Do not shut off domestic hot water circulating pumps for proper operation of the installed Symmons hot water tempering valve. ■ Take sample of all heating water/glycol solutions from each residential unit. Arrange of measure water ph and glycol type and percentAge by qualified water treatment company. Confirm that water/glycol solution meets all ph and chemical composition requirements stated by Weil McLain (boiler manufacturer) within standard installation manuals for Ultra 2 boilers. servicing, ■ Provide suitable access to all valves and coils requiring periodic P, observation or balancing. • Clean all strainers within hydronic piping systems. • Inspect and replace existing in-line boiler condensate neutralization device to insure proper on-going operation. ■ Purge entrapped air from all closed loop hydronic piping systems. • Repalr/replace covitating pumps and/or impOlars for P-6 (two locations). Perform full hydronic water balance by qualified Test, Adjust and Balancing contractor. Insure that all boilers, valves and controls are operating in accordance with manufacturer's standard installation requirements. • Perform re-balance of all Symmons domestic hot water tempering valves under dircction of Symmons factory representative. umma Uncontrolled heat is being delivered to rooms/areas outside of the boiler rooms within Several dwelling units at Gore Creek. Plane. The boilers are of high-efficiency sealed combustion design. The lack of traditional combustion and ventilation air results in hot and stuffy boiler rooms. Numerous metal pipe and ductwork surfaces are non-insulated or poorly insulated. This increases the neat transfer from/to these surface* under normal heating operations. The boiler primary circulating pumps are running during the summer months on a call for domestic hot wster heating in all but two dwelling units. This over-pressurizes the associated snow melt and radiant floor heating piping systems, causing these to heat up, wasting energy and contributing to the overheating of the boiler rooms and surrounding spaces. Two boilers tire and operate when the load required does not justify the opcrotion of two boilers. The quality of installation of pipes and associated insulation in some units is poor.

Reco en o s it is necessary to ventilate the boiler room to reduce the boiler room air, ceiling and wall temperature's, insulate the fan coil supply duct, install a thermal break iii the supply ducts, and prevent gravity thermo-siphoning of air through the dormant but heated supply ducts. We suggest dial strong consideration be given to modifying the controls and piping to accommodate lead-tag boiler operation (According to the schedule on sheet UM1.0, the hoat loss from a unit A is merely 87,400 btu/hour and the heat loss from a unit B is 78,500 btu/hour. Assuming that the radiant heating quantities match the design heat loss from these residential units, the individual unit heat losses represent roughly 40% of a single boilers altitude derated capacity). The factory boiler controls are capable of allowing the domestic hot water heating circulator operation without the primary boiler operating pumps on. These controls should be adjusted for this mode of operation at all units (currently observed at two units only). The hydronie piping systems should be balanced by a qualified test, adjust and balance firm to insure operation at desired flows, as indicated on the drawings (dnd in some cases verified by the design engineer). We recommend the following system modifications be employed to negate boiler room overheating: • Perform a diligent job making certain that all heating piping and domestic hot water piping and valves are well insulatPri. • insulate exposed supply ducts within boiler rooms and ceiling cavities with 3 inch thick fiberglass duct wrap, 3/a pcf density or equivalent • Install flexible duct connector on exposed fan coil unit supply ducts M near as possible to boiler room side of demising wall between boiler room and adjacent room. Leavc a minimum of 2 inchps of slack in flexible duct (fire retardant neoprene, or equal). * Install a gravity backdraft damper in fan coil supply duct near discharge from fan coil unit. Insure that backdraft damper opens upon fan energizing and closes via gravity when fan is dormant (gravity backdraft damper blades should provide suitable resistanoe to natural air flow and resultant convective heat transfer during dormant fan coli conditions.) • Install nominal 300 cfm inline duct fan within boiler room. Connect fan inlet with 8 inch diameter conical spin-in fitting wtth manual volume dampcr (mvd) to existing outside air intake duct. This existing outside air duct is exposed in comer of unit A boiler rooms and is niAnide boiler room notch at south side of unit B boiler rooms. Install 8 inch diameter fan inlet duct with a 6 inch diameter tee fitting in fan inlet duct. Connect 6 inch diameter open end duct with motorized normally closed 2 4A position damper into ceiling plenum above boiler room where suspended ceiling is installed, and open to boiler room where suspended ceiling is not installed in boiler room to tee fitting branrh duct. Install 8 inch diameter fan outlet duct to ceiling plenum where ceiling is installed or open to boiler room where ceiling is not installed. Install 18" x 6" transfer grille in suspended ceiling of boiler room if suspended ceiling is installed in boiler room. Arrange W maximize air circulation above suspender) ceiling. Control duct fan with an adjustable reverse acting thermostat installed on wall above susrionded boiler room ceiling, or on boiler room wall high in room where no suspended ceiling is installed.
