VARIABLE CONTROL

OPERATION

The variable control valve can be set to any heat setting and flame height de- sired, by simply turning the control knob until that setting is attained. Even the lowest setting provides realistic flames and glowing embers from two burners. Selecting higher settings produces greater heat output. This results in increased heating comfort.

INSPECTING WARNING: Do not operate heater between pilot and high positions.

PILOT FLAME PATTERN CAUTION: Do not try to adjust heating levels by using the manual shutoff valve.

INSPECTING

BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 44 shows a correct pilot flame pattern. Figure 45 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touch- ing the thermocouple. This will cause the thermocouple to cool. When the thermo- couple cools, the fireplace will shutdown.

If pilot flame pattern is incorrect, as shown in Figure 44

turn fireplace off (seeTo Turn Off Gas to Appliance, page 17 [Thermostat-con- trolled models] or column 1, this page, [Manually-controlled models])

see Troubleshooting, pages 21 through 23

FRONT BURNER FLAME PATTERN

Figure 46 shows correct front burner flame pattern. Figure 47 shows incorrect front burner flame pattern. The incorrect burner flame pattern shows yellow tipping at top of blue flame.

Manual background WARNING: If front burner flame pattern shows yellow tip- ping, your fireplace could pro- duce increased levels of carbon monoxide. Follow instructions at bottom of this page. Yellow flame on rear burner is normal.

NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles are burned by fireplace, causing brief patches of orange flame.

If front burner flame pattern is incorrect, as shown in Figure 47

turn fireplace off (seeTo Turn Off Gas to Appliance, page 17 [Thermostat-con- trolled models] or column 1, this page, [Manually-controlled models])
