4. Press the POWER and LOCK buttons
together to turn off the replace.
Note: Do not leave the hand-held remote in the
AUTO mode close to the replace. The radiant
heat from the replace will turn off the replace.
Ideally, place the hand-held remote in the center
of the room facing towards the replace.
Note: Do not hold the hand-held remote for
a long time. Body temperature will affect its
operation in the AUTO mode.
Safety Features
When away from home for an extended period
of time or as a child safety feature to prevent
accidental ignition of the replace, the receiver
ON/OFF/REMOTE switch should be in the
OFF position.
Auto Shutoff Feature
1. If the average room temperature exceeds 82°
Fahrenheit (28° Centigrade), the hand-held
remote control will perform a safety override
and shut the replace 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 replace after 8 minutes.

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.
INSPECTING BURNERS
Check pilot ame pattern and burner ame pat-
terns often.
PILOT FLAME PATTERN
Figure 23 shows a correct pilot ame pattern.
Figure 24 shows an incorrect pilot ame pattern.
The incorrect pilot flame is not touching the
thermocouple. This will cause the thermocouple
to cool. When the thermocouple cools, the heater
will shut down.
If pilot ame pattern is incorrect, as shown in
Figure 24
turn heater off (see To Turn Off Gas to Appli-
ance, page 17)
see Troubleshooting, page 22
Note: The pilot ame on natural gas units will
have a slight curve, but ame should be blue and
have no yellow or orange color.
