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 thermo-
stat 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
applications. For positioning the thermostat
sensing bulb elsewhere, an adhesive-backed
mounting clip is available.
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
retaining clamp (see Figure 32).
Note:
Do not remove the screw. Make
sure you tighten the screw after remov-
ing the thermostat sensing bulb.
IMPORTANT:
Do not force or bend the
thermostat sensing bulb or capillary. A
crimped capillary will not allow ther-
mostat to operate properly. It cannot be
repaired, the valve must be replaced.
3. The thermostat sensing bulb may be
located to the lower right front side of
fireplace. Determine location of sens-
ing bulb, but do not mount sensing bulb
until step 5. If you have a masonry fire-
place, see Figure 33 for location.
If you have a factory-built metal fire-
place, see Figure 34 for location.
If your fireplace has glass doors, posi-
tion sensing bulb directly behind door
gap on right bottom side (see Figure 35).

4. The mounting clip must be a minimum
of 3" from bottom of fireplace to pre-
vent crimping of capillary. Once you
have decided on a location, clean the
area thoroughly. Remove the paper
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 bot-
tom (see Figure 36). Slide the thermo-
stat sensing bulb into the clip.
IMPORTANT:
Do not crimp capillary.
