MAIN BURNER
Periodically inspect all burner flame holes with
the heater running. All slotted burner flame holes
should be open with yellow flame present. All
round burner flame holes should be open with a
small blue flame present. Some burner flame holes
may become blocked by debris or rust, with no
flame present. If so, turn off heater and let cool.
Remove blockage, blocked burner flame holes
will create soot.
INSPECTING BURNERS
Check pilot flame pattern and burner flame pat-
terns often.

Safety Features
Safety Features
When away from home for an extended period
of time or as a child safety feature to prevent
accidental ignition of the fireplace, the receiver
ON/OFF/REMOTE switch should be in the
OFF position.
Auto Shutoff Feature
Auto Shutoff Feature
1. If the average room temperature exceeds
82 degrees Fahrenheit (28 degrees Centi-
grade), the hand-held remote control will
perform a safety override and shut the
fireplace off. This feature is not available
in the MANU mode.
2. The receiver continuously receives signals
from the hand-held remote to control the
room temperature. If the hand-held remote
is misplaced, obstructed or for any reason
cannot transmit to the receiver, the receiver
will shut off the fireplace after 8 minutes.
Key Pad Lock Feature
This feature allows the user to lock/unlock
the keypad on the hand-held remote in the
MANU or AUTO mode to prevent inadvertent
operation (i.e. children operating the hand-held
remote control, etc.). The keypad is locked in
either on or off. Press the POWER and LOCK
buttons together to turn the unit on or off.
