5.
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 verti-
cally with the capillary at the bottom
(see Figure 43). Slide the thermostat
sensing bulb into the clip.
IMPORTANT:
Do not crimp capillary.

POSITIONING OF
THERMOSTAT
SENSING BULB
For Masonry and
Factory-built
Metal Fireplace
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 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 applica-
tions. For positioning the thermostat sens-
ing bulb elsewhere, an adhesive-backed
mounting clip is available.
Tools needed: 1/4" hex driver or socket
Figure 37 - Location of Gas Valve Assem-
bly and Thermostat Sensing Bulb
1.
Remove logs. Locate the gas valve as-
sembly and thermostat sensing bulb
(see Figure 37).
2.
The adhesive-backed mounting clip
(see Figure 38) is attached to the ther-
mostat sensing bulb. Remove the ad-
hesive-backed mounting clip.
3.
With 1/4" hex driver or socket, loosen
the thermostat screw. Carefully slide
the thermostat sensing bulb out of the
retaining clamp (see Figure 39).
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.
4.
The thermostat sensing bulb may be lo-
cated to the lower right front side of fire-
place. Determine location of sensing
bulb, but do not mount sensing bulb until
step 5. If you have a masonry fireplace,
see Figure 40 for location. If you have
a factory-built metal fireplace, see Fig-
ure 41 for location. If your fireplace has
glass doors, position sensing bulb di-
rectly behind door gap on right bottom
side (see Figure 42).
