vapors, liquids or sources of hydrocarbons in the
vicinity of the boiler or any other appliance.
3. Do not store or use halogen-containing products
(bleaches, cleaners, fabric softeners, refrigerants,
chemicals, etc.) in the vicinity of the boiler.
B. Inspect Inlet Air and Vent System (Monthly). Check
the following. If corrective action is required contact
qualied 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.
7. Condensate drain (if used) must have minimum 6
inch trap and allow condensate to ow freely. To
clean:
a. Disconnect condensate drain from drain tting.

c. Securely fasten condensate drain to drain tting,
providing gas-tight and water-tight seal.
C. Inspect Pilot and Main Burner Flames (Monthly).
1. Remove jacket front panel.
2. View ames through combustion area enclosure.
See Figure 1.
3. Adjust thermostat to highest setting.
4. Check pilot ame. See Figure 4. The pilot produces
