2. Remove the thermostat sensing bulb out
of the plastic clip (see Figure 22).
IMPORTANT: Do not force or bend the ther-
mostat 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 5. If
you have a masonry fireplace, (see Figure
21 for location). If you have a factory-built
metal fireplace, see Figure 20 for location.
If your fireplace has glass doors, position
sensing bulb directly behind door gap on
right bottom side (see Figure 23).
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, thoroughly clean the
area. Remove the paper backing from the
adhesive on back of mounting clip (pro-
vided with the heater in hardware pack-
age) (see Figure 19). 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
24). Slide the thermostat sensing bulb into
the clip.
