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 on the left side of the base assembly. This location allows the thermostat to keep the room temperature at an ideal comfort level for most fireplace applica- tions. For positioning the thermostat sensing bulb elsewhere, an adhesive-backed mounting clip is available.

1.Locate the gas valve assembly and thermostat sensing bulb (see Figure 44).

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 fireplace. Determine location of sensing bulb, but do not mount sensing bulb until step 4. 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 fireplace 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.
