OPTIONAL POSITIONING OF THERMOSTAT SENSING BULB
FOR MASONRY AND FACTORY- BUILT METAL FIREPLACE
If your log set cycles to pilot, but the room temperature drops to a lower than ideal comfort level before the log set comes back on, you may want to reposition the thermostat sensing bulb.
The thermostat sensing bulb is located on the gas valve assembly. This location allows the thermostat to keep the room temperature at an ideal comfort level for most fireplace appli- cations. If positioning the thermostat sensing bulb elsewhere, follow these directions.
Tools needed: 5/16" hex driver or socket
1.Locate the gas valve assembly and ther- mostat sensing bulb (see Figure 30).

2.With 5/16” hex driver or socket, loosen the thermostat screw. Carefully slide the thermostat sensing bulb out of the retain- ing clamp (see Figure 31).
Note: Do not remove screw. Make sure you tighten screw after removing thermo- stat sensing bulb.
IMPORTANT: Do not force or bend ther- mostat sensing bulb or capillary.
3.The thermostat sensing bulb may be located to the lower right front side of fireplace. Place bulb in an area that will be close to room temperature when log set is operating
