For position-ing the thermostat sensing bulb elsewhere, an adhesive-backedmounting clip is available.Tools needed: 5/16" hex driver or socket1. Locate the gas valve assembly and thermostat sensing bulb(see Figure 40).2. With 5/16" hex driver or socket, loosen the thermostat screw.Carefully slide the thermostat sensing bulb out of the retainingclamp (see Figure 42).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 43 for location.If you have a factory-built metal fireplace, see Figure 44 forlocation.If your fireplace has glass doors, position sensing bulb directlybehind door gap on right bottom side (see Figure 45).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 (seeFigure 46). Slide the thermostat sensing bulb into the clip.IMPORTANT: Do not crimp capillary.Figure 40 - Location of Gas Valve Assembly and ThermostatSensing BulbThermostatSensing BulbGas Valve AssemblyFigure 41 - Adhesive-backedMounting ClipFigure 42 - RemovingThermostat Sensing BulbFigure 43 - Locating ThermostatSensing Bulb on MasonryFireplaceFigure 44 - Locating ThermostatSensing Bulb on Factory-builtMetal FireplaceQQQ¢¢¢Adhesive-backedMountingClipThermostat Sensing BulbFigure 45 - Installing ThermostatSensing Bulb behind GlassDoorsFigure 46 - Positioning theThermostat Sensing Bulb inthe Vertical Position with theCapillary at the BottomQQQQ¢¢¢¢Q¢QQQQ¢¢¢¢Adhesive-backedMountingClipGlass DoorsThermostat Sensing BulbCapillaryThermostat Sensing BulbDo NotCrimpCapillaryAdhesive-backedMountingClipAdhesive-backedMountingClipThermostat Sensing BulbOPTIONAL POSITIONING OF THERMOSTAT SENSING BULB(THERMOSTAT-CONTROLLED MODELS ONLY)For Masonry and Factory-Built Metal Fireplace
