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 allows the 

thermostat to keep the room temperature at 

an ideal comfort level for most fireplace appli-

cations. If positioning the thermostat sensing 

bulb elsewhere, follow these directions.
Tools needed: 5/16" hex driver or socket
1.  Locate the gas valve assembly and ther-

mostat sensing bulb (see Figure 30).

2.  With  5/16”  hex  driver  or  socket,  loosen 

the thermostat screw. Carefully slide the 

thermostat sensing bulb out of the retain-

ing clamp (see Figure 31).

 

 

IMPORTANT: Do not force or bend ther-

mostat sensing bulb or capillary.

3.  The thermostat sensing bulb may be 

located  to  the  lower  right  front  side  of 

fireplace. Place bulb in an area that will 

be close to room temperature when log 

set is operating
