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 maywant 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 elsewhere, an adhesive-backed mounting clip has been provided.

Tools needed: 1/4" hex driver or socket

l. Remove logs. Locate the gas valve assembly and thermostat sensing bulb (see Figure 27).

3, With 1/4" hex driver or socket, loosen the thermostat screw. Carefully slide the thermo- stat sensing bulb out of the retaining clamp (see Figure 29).

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,

4.The thermostat sensing bulb may be located to the lower fight front sid_ of fireplace. Determine location of sensing bulb, but do not mount sensing bulb until step 5. If you

have a masonry fireplace, see Figure 30 on page 30 for location. Continued I
