THERMOSTAT

CONTROL OPERATION

The thermostatic control used on this heater differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat used on this heater senses the room temperature. The thermostat adjusts the amount of gas flow to the burner. This increases or de- creases the burner flame height. At times the room may exceed the set tempera- ture. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set tem- perature. The control knob can be set to any heat level between HI and LO.

Note: The thermostat sensing bulb mea- sures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, installation loca- tion, room size, open air temperatures, etc.). Frequent use of your heater will let you determine your own comfort levels.

MANUAL LIGHTING

PROCEDURE

1.Remove front panel (see Figure 2, page 4).

2.Follow steps 1 through 5 under Light- ing Instructions, page 15.

3.With control knob pressed in, strike match. Hold match to pilot until pi- lot lights.

4.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob.

5.Replace front panel.

6.Turn control knob counterclockwise

C-clockwiseto desired heating level. The main burner should light. Set control knob to any heat level between HI and LO.

INSPECTING

BURNER

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 26 shows a correct pilot flame pattern. Figure 27 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 heater will shut down.

BURNER FLAME PATTERN

Figure 28 shows a correct burner flame pattern. Figure 29 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows yellow tipping of the flame. It also shows the flame higher than one inch above the log.

Note: When using the heater the first time, the flame will be yellow for approximately one hour until the log cures.

WARNING: If yellow tipping occurs, your heater could pro- duce increased levels of carbon monoxide. If burner flame pattern shows yellow tipping, follow in- structions at bottom of this page.

NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn causing brief patches of orange flame.
