WARNING

Turn off gas before servicing fireplace. It is recommended that a qualified service technician perform these

check-ups at the beginning of each heating season.

The appliance area must be kept clear and free from combustible materials, gasoline and other flammable

vapors and liquids. The flow of combustion and ventilation air must not be obstructed.

Burner, Pilot and Control Compartment:

Keep the control compartment, logs, and burner areas surrounding the logs clean by vacuuming or brushing at least twice a year. Make sure the pilot air intake is free of obstructions at all time.

Standing-Pilot Flame Only:

The flames from the pilot should be visually checked as soon as the heater is installed and periodically during normal operation. The pilot flame must always be present when the fireplace is in operation. Refer to Figure 23: Pilot Flame Appearance. The pilot flame has three distinct flames, one engulfing the thermopile, one engulfing the thermocouple (which is not connected to the valve), and the other reaching to the main burner.

Burner Flame:

Thermopile

Figure 23: Pilot Flame Appearance

The flames from the burner should be visually checked as soon as the heater is installed and periodically during normal operation. In normal operation, at full rate, and after approximately 15-30 minutes, the flame appearance in Figure 24: Burner Flame Appearance should be observed.

NOTE

The type of installation, vent system configuration, and wind effects may cause the flame patterns to vary.
