If your fireplace has glass doors, position
sensing bulb directly behind door gap on
right bottom side (see Figure 49).
4. The mounting clip must be a minimum
of 3" from bottom of fireplace to prevent
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 bottom (see Figure 50). Slide the
thermostat sensing bulb into the clip.
IMPORTANT:
Do not crimp capillary.
