Built Metal Fireplace; Optional Positioning Of Thermostat Sensing Bulb - Desa CRL3124PA/NA Owner's Operation And Installation Manual

OPTIONAL 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 applications. For positioning
the thermostat sensing bulb elsewhere, an
adhesive-backed mounting clip is available.
Tools needed: 1/4" hex driver or socket
1. Remove logs. Locate the gas valve as-
sembly and thermostat sensing bulb (see
Figure 37).
2. With 1/4" hex driver or socket, loosen the
thermostat screw. Carefully slide the ther-
mostat sensing bulb out of the retaining
clamp (see Figure 39).
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 4. If you
have a masonry fireplace, see Figure 40
for location. If you have a factory-built
metal fireplace, see Figure 41 for location.
If your fireplace has glass doors, position
sensing bulb directly behind door gap on
right bottom side (see Figure 42).
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
