M. MAINTENANCE INSTRUCTIONS

1.CLEANING THE BURNER AND CONTROL COMPARTMENT

Keep the burner and control compartment clean by brushing and vacuuming at least once a year. Failure to do this may shorten the fan’s life (where applicable). Always turn off the wall switch (or remote control) and gas valve before cleaning.

2.CHECKING FLAME PATTERNS

Visually check the flame of the burner periodically, making sure the flames are steady, not lifting or floating. The flame color should be blue with yellow tips. The sensor (intermittent pilot) or thermopile and thermocouple (standing pilot) tips should be covered with flame. See Figures 26 and 27.

If the vent configuration is installed incorrectly, the vent may cause the flames inside the appliance to lift or “ghost”, which is a dangerous situation. Inspect the flames after installation to ensure proper performance. See Figure 28. If the vent configuration is correct, yet the flames are lifting or ghosting, shut off gas to the appliance and contact the dealer you purchased the appliance from.

Note: The look of the flames and embers may differ based on the type of fuel and venting assembly that is required.
