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 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.

1.Locate the gas valve assembly and thermostat 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 fireplace. De- termine 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 capil- lary at the bottom (see Figure 36). Slide the thermostat sensing bulb into the clip.

IMPORTANT: Do not crimp capillary.
