OPTIONAL POSITIONING OF THERMOSTAT SENSING BULB
(Thermostat-Controlled Models Only)
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 thermostat 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 applications. For positioning the thermostat sensing bulb else- where, an

1. | Remove logs. Locate the gas valve assembly and thermostat |
| sensing bulb (see Figure 40). |
2. | With 1/4" hex driver or socket, loosen the thermostat screw. |
| Carefully slide the thermostat sensing bulb out of the retaining |
| clamp (see Figure 42). |
| Note: Do not remove the screw. Make sure you tighten the |
| screw after removing the thermostat sensing bulb. |
| IMPORTANT: Do not force or bend the thermostat sensing |
| bulb or capillary. |
3. | The thermostat sensing bulb may be located to the lower right |
| front side of fireplace. Determine location of sensing bulb, but |

do not mount sensing bulb until step 5. If you have a masonry |
fireplace, see Figure 43 for location. If you have a factory- |
built metal fireplace, see Figure 44 for location. If your fire- |
place has glass doors, position sensing bulb directly behind |
door gap on right bottom side (see Figure 45). |

4. The mounting clip must be a minimum of 3" from bottom of |
fireplace 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. Press |
the clip into the new location so that the thermostat sensing bulb |
will be positioned vertically with the capillary at the bottom |
(see Figure 46). Slide the thermostat sensing bulb into the clip. |
IMPORTANT: Do not crimp capillary. |
