OPTIONAL POSI- TIONING OF THER- MOSTAT 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 repositionthethermostatsensingbulb.

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.

4.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 44). Slide the thermostat sensing bulb into the clip.

IMPORTANT: Do not crimp capillary.

1. Remove logs. Locate the gas valve as-

sembly and thermostat sensing bulb

(see Figure 38).

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 40).

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.

3. The thermostat sensing bulb may be

located to the lower right front side of

fireplace. Determine location of sens-
