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 thermo- stat sensing bulb.

The thermostat sensing bulb is located on the gas valve 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.

Tools needed: 5/16" hex driver or socket

1.Locate the gas valve assembly and ther- mostat sensing bulb (see Figure 30).

2.With 5/16" hex driver or socket, loosen the thermostat screw. Carefully slide the thermostat sensing bulb out of the retaining clamp (see Figure 32).

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. A crimped capillary will not allow ther- mostat to operate properly. It cannot be repaired, the valve must be replaced.

3.The thermostat sensing bulb may be located to the lower right front side of fireplace. Determine location of sens- ing bulb, but do not mount sensing bulb until step 5. If you have a masonry fire- place, see Figure 33 for location.

If you have a factory-built metal fire- place, see Figure 34 for location.

If your fireplace has glass doors, posi- tion 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 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 vertically with the capillary at the bot- tom (see Figure 36). Slide the thermo- stat sensing bulb into the clip.

IMPORTANT: Do not crimp capillary.
