Proof of Fire Switch

This switch needs to be removed and cleaned after every 100 bags of fuel burned.

Cleaning Procedure:

1)UNPLUG STOVE!

2)Locate the switch behind the right side panel, mounted on the com- bustion blower.

3)Using a flat-head screwdriver, remove the 2 screws which secures the switch to the blower housing.

4)Using a dry cloth, wipe off any flyash build-up on the sensor portion of the switch.

5)Reinstall switch. Ensure wires are properly connected to the switch and the connectors are not making contact with the blower housing. Close side panel.

Note: Failure to clean the proof of fire switch when needed may result in nui- sance shut-downs because the fly-ash build-up insulates heat from reaching the switch.

(Recommended Frequency of 1 year or after every 100 bags of fuel used)

Window Wash

Soot and Flyash:

Formation and need for removal - The products of combustion will contain small particles of flyash. The flyash will collect in the exhaust venting system and restrict the flow of the flue gases. Incomplete combustion, such as occurs during startup, shutdown, or incorrect operation of the room heater will lead to some soot formation which will collect in the exhaust venting system. The exhaust venting system should be inspected at least once every year to determine if cleaning is necessary.
