User Maintenance
A. General Housekeeping (Continuous).
1. Keep boiler area clear and free of combustible
materials and obstructions to the free flow of
combustion and ventilation air to the boiler.
2. Do not store or use gasoline or other flammable
vapors or liquids in the vicinity of the boiler or any
other appliance.
3. Do not store or use sources of hydrocarbons in
the vicinity of the boiler. Sources of hydrocarbons
include bleaches, cleaners, chemicals, sprays, paint
removers, fabric softeners and refrigerants.
B. Inspect Inlet Air and Vent System (Monthly). Check
the following. If corrective action is required contact
qualified service agency.
1. Inlet air terminal and vent terminal must be free of
obstruction, undamaged, with screens securely in
place.
2. Inlet air terminal, vent terminal, and wall thimble (if
used) must be weather-tight.
3. Inlet air pipe and vent pipe must be full round
shape, showing no damage from impact or excessive
temperature.
4. Inlet air pipe and vent pipe must be supported at
minimum 5 foot intervals and must not sag.
5. All inlet pipe joints must be secure and airtight.
6. All vent pipe joints must be secure and watertight.
C. Inspect Condensate Drain Trap and Drain Line
(Monthly).
1. Inspect condensate trap water level. If low, add
water to bring level to trap discharge.
2. Ensure condensate can flow freely to drain.
D. Inspect Pilot and Main Burner Flames (Monthly).
1. Remove jacket front panel. See Figure 2.
2. View flames through Flame Observation Port. See
Figure 1.
3. Adjust thermostat to highest setting.
4. Check pilot flame. See Figure 5. The pilot produces
three (3) flames. The center flame should be steady,
medium hard blue enveloping 3/8to ½ inch of
sensing probe. If flame is yellow and lazy, follow
instructions TO TURN OFF GAS TO APPLIANCE
(see Figure 3), and contact qualified service agency.
5. Check main burner flames. See Figures 6 and 7.
Flame should have clearly defined inner cone with
no yellow tipping. Orange-yellow streaks caused
by dust should not be confused with true yellow
tipping. If yellow flames are observed, follow
instructions TO TURN OFF GAS TO APPLIANCE
(see Figure 3), and contact qualified service agency.
6. Adjust thermostat to normal setting.
E. Schedule Inspection by Qualified Service Agency
(Annual or at Beginning of Heating Season). For
continued safe operation a qualified service agency
must provide a more detailed inspection of burners, heat
exchanger and vent system, and provide maintenance
as specified in Installation, Operating and Service
Instructions.
