Thermostatic Control
The thermostat control knob can be set to any comfort level between “HI” and “LO”. The thermostat will gradually modulate the heat output and flame height from higher to lower settings in order to maintain the comfort level you select. The ideal comfort setting will vary by household depending upon the amount of space to be heated, the output of the central heating system, etc.
NOTE: Selecting the “HI” setting with the control knob will cause the burner to remain fully on, without modu- lating down in most cases.
Positions of Thermostat Sensing Bulb
The thermostat sensing bulb can be found on the gas valve assembly. Instructions follow for placement of this bulb to achieve proper thermostatic operation.
1.Locate the gas valve assembly and thermostat sensing bulb. (Fig. 8)
2.The thermostat sensing bulb has been placed in the best location by the manufacturer.
NOTE: If the room temperature drops to a lower than ideal comfort level even at the highest setting, you may want to use some sort of mounting clip or bracket (not provided) to reposition the thermostat sensing bulb in the locations listed below.

Determining Sensing Bulb Location
The thermostat sensing bulb can be attached to a new position by mounting a bracket or mounting clip (not provided) in the following locations and placing the sensing bulb into this bracket.
1.The thermostat sensing bulb may be located to the lower right front side of the fireplace. Determine location of sensing bulb depending on which kind of fireplace you have.

2.The best way to mount the sending bulb is to position it vertically with the capillary at the bottom.
NOTE: Do not crimp capillary.
3.If you have a masonry fireplace, refer to Figure 9.
4.If you have a factory built metal fireplace, refer to Figure 10.
5.If your fireplace has glass doors, position sensing bulb directly behind door gap on right bottom side. (Fig. 11)
