To inspect base insulation:
The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials. See WARNING above. Failure to comply could result in severe personal injury.
Make sure base insulation is secure against base front and back panels. If base insulation is damaged or displaced, do not operate boiler. Replace or reposition insulation.
Failure to replace damaged insulation or reposition insulation can result in a fire hazard, causing severe personal injury, death or substantial property damage.
To place in operation:
1.Make sure boiler is filled with water.
2.Follow lighting/operating instructions on boiler.
PROPANE BOILERS ONLY – Your propane supplier mixes an odorant with the propane to make its presence detectable. In some instances, the odorant can fade, and the gas may no longer have an odor.
Propane gas can accumulate at floor level. Smell near the floor for the gas odorant or any unusual odor. If you suspect a leak, do not attempt to light the pilot.
•Use caution when attempting to light a propane pilot. This should be done by a qualified service technician, particularly if pilot outages are common.
•Periodically check the odorant level of your gas.
•Inspect boiler and system at least yearly to make sure all gas piping is
•Consult your propane supplier regarding installation of a gas leak detector. There are some products on the market intended for this purpose. Your supplier may be able to suggest an appropriate device.

b)High limit setting below boiler water temperature?
c)Thermostat setting below room temperature?
d)Gas not turned on at meter?
e)Gas not turned on at boiler?
f)If above fails to eliminate the trouble, refer to Control Supple- ment.
