SENSING BULB

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 near the gas valve assembly on the mounting
bracket. This location allows the thermostat to keep the room temperature at an ideal
comfort level for most fireplace applications. For positioning the thermostat sensing bulb
elsewhere, an adhesive-backed mounting clip has been provided.
Tools needed: 1/4" hex driver or socket
Figure 27 - Location of Gas Valve Assembly and Thermostat Sensing Bulb
1. Remove logs. Locate the gas valve assembly and thermostat sensing blub (see Figure 27).
2. The adhesive-backed mounting clip (see Figure 28) is attached to the thermostat sensing
bulb. Remove the adhesive-backed mounting clip.

3. With 1/4" hex driver or socket, loosen the thermostat screw. Carefully slide the thermo-
stat sensing bulb out of the retaining clamp (see Figure 29).
Note: Do not remove the screw. Make sure you tighten the screw after removing the
thermostat sensing bulb.
IMPORTANT: Do not force or bend the thermostat sensing bulb or capillary.
4. The thermostat sensing bulb may be located to the lower right front side of fireplace.
Determine location of sensing bulb, but do not mount sensing bulb until step 5. If you
have a masonry fireplace, see Figure 30 on page 30 for location.
