Figure 35 shows a correct pilot ame pattern.
Figure 36, shows an incorrect pilot ame pat-
tern. The incorrect pilot ame is not properly
heating the thermocouple. When the ther-
mocouple cools, the heater will shut down.
If pilot ame pattern is incorrect, as shown
in Figure 36
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 21)
• see Troubleshooting, page 25
Note: The pilot ame on natural gas units will
have a slight curve, but the ame should be
blue and have no yellow or orange color.

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 reaches
a range of 82° F (28° C) to 92° F (33° C),
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 sig-
nals 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. This will
occur in 8 or more minutes depending
upon location of remote transmitter and
strength of batteries.

eration (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.
