This location allows the thermostat to keepthe room temperature at an ideal comfort level for most fireplaceapplications. For positioning the thermostat sensing bulb else-where, an adhesive-backed mounting clip is available.Tools needed: 1/4" hex driver or socket1. Remove logs. Locate the gas valve assembly and thermostatsensing bulb (see Figure 43).2. With 1/4" hex driver or socket, loosen the thermostat screw.Carefully slide the thermostat sensing bulb out of the retainingclamp (see Figure 45).Note: Do not remove the screw. Make sure you tighten thescrew after removing the thermostat sensing bulb.IMPORTANT: Do not force or bend the thermostat sensingbulb or capillary.3. The thermostat sensing bulb may be located to the lower rightfront side of fireplace. Determine location of sensing bulb, butdo not mount sensing bulb until step 5. If you have a masonryfireplace, see Figure 46 for location. If you have a factory-builtmetal fireplace, see Figure 47 for location. If your fireplacehas glass doors, position sensing bulb directly behind door gapon right bottom side (see Figure 48).4. The mounting clip must be a minimum of 3" from bottom offireplace 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. Pressthe clip into the new location so that the thermostat sensing bulbwill 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.Figure 44 - Adhesive-backed Mounting ClipFigure 45 - Removing Thermostat Sensing BulbThermostatSensing BulbGas ValveAssemblyMountingBracketThermostatScrewRetainingClampThermostatSensing BulbCapillaryOPTIONAL POSITIONING OF THERMOSTAT SENSING BULBAdhesive-backedMountingClipThermostatSensing BulbFigure 49 - Positioning theThermostat Sensing Bulb inthe Vertical Position with theCapillary at the BottomCapillaryThermostatSensing BulbDo Not CrimpCapillaryAdhesive-backedMounting Clip
