If your log set cycles to pilot, but room tem
-
perature drops to a lower than ideal comfort
level before log set comes back on, you may
want to reposition thermostat sensing bulb.
Thermostat sensing bulb is located near gas
valve assembly on mounting bracket. This
location allows the thermostat to keep room
temperature at an ideal comfort level for most
fireplace applications. For positioning thermo
-
stat sensing bulb elsewhere, an adhesive-
backed mounting clip is available.
Tools needed: 1/4" hex driver or socket
1. Remove logs. Locate gas valve assem-
bly and thermostat sensing bulb (see
Figure 26).
2. With 1/4" hex driver or socket, loosen ther
-
mostat screw. Carefully slide thermostat
sensing bulb out of retaining clamp (see
Figure 28).
Note: Do not remove the screw. Make
sure you tighten screw after removing
thermostat sensing bulb.
IMPORTANT:
Do not force or bend ther-
mostat sensing bulb or capillary.
3. Thermostat sensing bulb may be located
in lower right front side of fireplace. De
-
termine location of sensing bulb, but do
not mount sensing bulb until step 4. If you
have a masonry fireplace, see Figure 29
for location. If you have a factory-built
metal fireplace, see Figure 30 for location.
If your fireplace has glass doors, position
sensing bulb directly behind door gap on
right bottom side (see Figure 31).
