OWNER’S MANUAL

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 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 52). Slide the thermostat sensing bulb into the clip.

IMPORTANT: Do not crimp capillary.
