This location allows the ther-mostat to keep the room temperature at an idealcomfort level for most fireplace applications. Forpositioning the thermostat sensing bulb elsewhere,an adhesive-backed mounting clip is available(see Figure 46).Tools needed: 5/16" hex driver or socket1. Locate the gas valve assembly and thermostatsensing bulb (see Figure 45).2. With 5/16" hex driver or socket, loosen thethermostat screw. Carefully slide the thermo-stat sensing bulb out of the retaining clamp(see Figure 47).Note: Do not remove the screw. Make sureyou tighten the screw after removing thethermostat sensing bulb.IMPORTANT: Do not force or bend thethermostat sensing bulb or capillary.3. The thermostat sensing bulb may be locatedto the lower right front side of fireplace. De-termine location of sensing bulb, but do notmount sensing bulb until step 4, page 34. Ifyou have a masonry fireplace, see Figure 48for location.If you have a factory-built metal fireplace, seeFigure 49 for location.If your fireplace has glass doors, positionsensing bulb directly behind door gap on rightbottom side (see Figure 50).Figure 45 - Location of Gas ValveAssembly and Thermostat Sensing BulbThermostatSensing BulbGas ValveAssemblyCapillaryScrew Retaining ClampThermostatSensing BulbFigure 46 - Adhesive-backed MountingClipFigure 47 - Removing ThermostatSensing BulbFigure 48 - Locating Thermostat SensingBulb on Masonry FireplaceFigure 49 - Locating Thermostat SensingBulb on Factory-built Metal FireplaceAdhesive-backedMountingClipThermostatSensing BulbAdhesive-backedMounting ClipThermostatSensing BulbFigure 50- Installing Thermostat SensingBulb behind Glass DoorsAdhesive-backedMounting ClipGlass DoorsThermostatSensing Bulb
