FOR MASONRY AND FACTORY-
BUILT METAL FIREPLACE
If your log set cycles to pilot, but the room tem
-
perature 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 is available.
1. Locate the gas valve assembly and ther-
mostat sensing bulb (see Figure 32).
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 locat-
ed 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
34 for location. If you have a factory-built
metal fireplace, see Figure 35 for location.
If your fireplace has glass doors, position
sensing bulb directly behind door gap on
right bottom side (see Figure 36).
4. The mounting clip must be a minimum of 3"
from bottom of fireplace to prevent crimp
-
ing of capillary. Once you have decided
on a location, clean the area thoroughly.
Remove paper backing from adhesive on
back of mounting clip. Press clip into new
location so that the thermostat sensing
bulb will be positioned vertically with the
capillary at the bottom (see Figure 37).
Slide thermostat sensing bulb into clip.
IMPORTANT:
Do not crimp capillary.
