Table of Contents

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

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 burner porting, pilot air opening and burner air opening are free of obstructions at all times.

PILOT FLAME

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. See Figure 61. The pilot

flame has three distinct flames, one engulfing the thermopile, one engulfing the

thermocouple, and the other reaching to the main burner.

BuRNER

Inspect area around the injector. Remove any lint or foreign material with a

brush or vacuum.

BuRNER FLAME

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 operating for about

15 to 30 minutes, the flame should be yellow and slightly taller

than the rear log. See Figure 62.

If the flame is blue and only in the center, turn off unit and let

cool. After unit is cool, remove logs and check to make sure the

back holes in the burner are not covered with rock wool. If the

back holes are clear, add more rock wool to the center of the

burner. Replace logs.

NOTE: The type of installation, vent system

configuration, and wind effects may cause the flame

patterns to vary.
