Therefore, during setup care should be exercised in obtaining an excess 0 reading of not less than 2% or more than 7%. All Power Flame burners are operationally fire tested at the factory. CAPACITIES & SPECIFICATIONS Model Number NPM15-10-24 NPM15-10-120 NPM30A-12-120 NPM30-12-120 NPM50-15-120 Natural/LP Gas Flow 300-720... - Page 3 If the burner is to be mounted in an existing boiler or furnace, ensure that all fireside surfaces are clean and in good condition. All doors, clean outs, cracks or other openings allowing excess air into the combustion chamber should be tightly sealed, whether the burner is to be fired under positive or negative Combustion Chamber conditions.

Typical UL Gas Piping Train (Modulating Burner) Install pressure regulator (not used with combination gas valve/pressure regulator) directly upstream of main automatic gas valve(s) and fit drip leg and main gas cock upstream of regulator or automatic valve(s). The pilot line should be piped into the upstream tapped nipple to minimize pilot line piping length.
- Page 6 WIRING Refer to wiring diagram shipped with burner. Electrical installation must be made in accordance with the NEC, NFPA 70 or Canadian Electrical Code, Part 1 and applicable local codes. If this burner is part of a boiler or furnace package system, check- wiring diagram as supplied by the boiler or furnace manufacturer.
- Page 7 Connect a microampmeter or voltmeter to the Primary Safety Control as directed in the PSC manufacturer’s instruction bulletin to determine flame detection system values. The meter is normally connected in series with the (SENSE) terminal on the S8680 series control. With the main and leak test cocks and pilot cock in OFF position, turn on the gas cock at meter.
- Page 8 Figure 5A. Pilot Assembly – Flame Rod Type – Natural Gas/LP Gas – NPM15 – NPM50 – 120 Volt With the leak gas cock closed and pilot gas cock open; turn the burner switch ON. The blower motor will 7.11 purge the heat exchanger of any accumulated combustibles.
- Page 9 After the burner has completed pre-purge and established a good pilot flame signal reading, the main automatic fuel valve will be energized. As when setting up the pilot, static air pressure will also be evident on the gas manifold. This pressure will increase as the main gas valves open. The main flame should light immediately.

Page 10: Combustion Arrangement Requirements
COMBUSTION ARRANGEMENT REQUIREMENTS The NPM burner has been designed to fire with high combustion efficiency into combustion chambers with positive, balanced or negative pressures using natural or PROPANE gas only. In order to fire efficiently, the burner requires an adequate supply of combustion air. Ventilation to any enclosed area should be provided on the basis of 1/2 square inch of opening for each 1,000 BTU/HR input. -
