OPTIONAL POSITIONING OF
THERMOSTAT SENSING BULB

(Thermostat-Controlled Models Only)

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
applications. For positioning the thermostat sensing bulb else-
where, an adhesive-backed mounting clip is available.

Tools needed: 1/4" hex driver or socket

1.

Remove logs. Locate the gas valve assembly and thermostat
sensing bulb (see Figure 43).

2.

With 1/4" hex driver or socket, loosen the thermostat screw.
Carefully slide the thermostat sensing bulb out of the retaining
clamp (see Figure 45).

Note:

  Do not remove the screw. Make sure you tighten the

screw after removing the thermostat sensing bulb.

IMPORTANT:

 Do not force or bend the thermostat sensing

bulb or capillary.

3.

The thermostat sensing bulb may be located 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 46 for location. If you have a factory-
built metal fireplace, see Figure 47 for location. If your fire-
place has glass doors, position sensing bulb directly behind
door gap on right bottom side (see Figure 48).

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, clean the area thoroughly. Remove the pa-
per 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 49). Slide the thermostat sensing bulb into the clip.

IMPORTANT:

 Do not crimp capillary.
