UNVENTED (VENT-FREE) GAS LOG HEATER

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 thermostat sensing bulb.

The thermostat sensing bulb is located on the gas valve assembly. This location al- lows the thermostat to keep the room tem- perature at an ideal comfort level for most fireplace applications. For positioning the thermostat sensing bulb elsewhere, an adhe- sive-backed mounting clip is available.

Tools needed:

•5/16" hex driver or socket

1.

Locate the gas valve assembly and ther-

 

mostat sensing bulb (see Figure 31).

2.

With 5/16" hex driver or socket, loosen

 

the thermostat screw. Carefully slide

 

the thermostat sensing bulb out of the

 

retaining clamp (see Figure 33).

 

Note: Do not remove the screw. Make

 

sure you tighten the screw after remov-

 

ing the thermostat sensing bulb.

 

IMPORTANT: Do not force or bend the

 

thermostat sensing bulb or capillary. A

 

crimped capillary will not allow ther-

 

mostat to operate properly. It cannot be

 

repaired, the valve must be replaced.

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 vertically with the capillary at the bot- tom (see Figure 37). Slide the thermo- stat sensing bulb into the clip.

IMPORTANT: Do not crimp capillary.

located to the lower right front side of

fireplace. Determine location of sens-

ing bulb, but do not mount sensing bulb

until step 5. If you have a masonry fire-
