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
