Cleaning
When the fireplace is first activated, there may be some smoking and
a visible film may be left on the glass. This is a normal condition, and
is the result of burning of protective coatings on new metal.
■ Glass must be cleaned periodically to remove any film (which
is a normal by-product of combustion) which may be visible.
Film can easily be removed by removing the door, as shown in
section. Handle the door carefully, and clean it with non-abrasive,
non-ammonia based glass cleaners. One of the most effective
products is Kel-Kem.
■ Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and firebox free from dust and lint.
Procedure for Checking The Flue Gas Switch and
Thermal Switch
1). Remove the safety screen and outer glass, see appropriate
sections.
2). Disconnect the power vent harness from the plug in the control box.
3). Turn wall switch to 'ON' position.
4). Monitor the flue gas LED indicator for 2 minutes and ensure
that neither the LED indicator nor the ignitor illuminate. If LED
indicator or ignitor illuminates the flue gas switch is not functioning
properly. Disconnect the power to the unit, follow the trouble
shooting section or contact your technical support representative.
5). Using a heat gun, warm up the heat sensor located between
two glass panels until heat sensor LED turns off.
6). Confirm LED resets within 10 minutes.
7). Reconnect power vent wire harness and reinstall the outer
glass panel and safety screen.
