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 left side of the base
assembly. This location allows the thermostat to keep the room
temperature at an ideal comfort level for most fireplace applica-
tions. For positioning the thermostat sensing bulb elsewhere, an
adhesive-backed mounting clip is available.
1. Locate the gas valve assembly and thermostat sensing bulb
(see Figure 49).
2. Gently pull thermostat sensing bulb free from the retaining
clamp.
IMPORTANT: Do not force or bend the thermostat sensing
bulb or capillary.
3. 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 4. If you have a masonry
fireplace, see Figure 51 for location.
If you have a factory-built metal fireplace, see Figure 52 for
location.
If your fireplace has glass doors, position sensing bulb directly
behind door gap on right bottom side (see Figure 53).
4. The mounting clip must be a minimum of 3" from bottom of
fireplace to prevent crimping of capillary. Once you have de-
cided on a location, clean the area thoroughly. Remove the pa-
per backing from the adhesive on back of mounting clip. Press
the clip into the new location so that the thermostat sensing bulb
will be positioned vertically with the capillary at the bottom (see
Figure 54). Slide the thermostat sensing bulb into the clip.
IMPORTANT: Do not crimp capillary.
