Optional Positioning Of Thermostat Sensing Bulb - Desa CDR3924NT 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 tem-
perature 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 on
the left side of the base assembly. This loca-
tion allows the thermostat to keep the room
temperature at an ideal comfort level for most
fireplace applications. For positioning the ther-
mostat sensing bulb elsewhere, an adhesive-
backed mounting clip is available.
1. Locate the gas valve assembly and ther-
mostat sensing bulb (see Figure 31).
2. Gently pull thermostat sensing bulb free
from the retaining clamp.
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 fire-
place. Determine location of sensing bulb,
but do not mount sensing bulb until step 4.
If you have a masonry fireplace, see Figure
33 for location.
If you have a factory-built metal fireplace,
see Figure 34 for location.
If your fireplace has glass doors, position
sensing bulb directly behind door gap on
right bottom side (see Figure 35).
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 36). Slide
the thermostat sensing bulb into the clip.
IMPORTANT: Do not crimp capillary.
