OPERATING FIREPLACE
Continued
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.
Figure 34 shows a correct pilot ame pattern.
Figure 35 shows an incorrect pilot ame pattern.
The incorrect pilot ame is not touching the ther-
mocouple. This will cause the thermocouple to
cool. When the thermocouple cools, the replace
will shut down.
If pilot ame pattern is incorrect, as shown in
Figure 35
• turn replace off (see To Turn Off Gas to Ap-
pliance, page 20 or 22, depending on your
model.)
• see Troubleshooting, page 27
Note: The correct pilot ame on natural gas units
will have a slight curve, but ame should be blue
and have no yellow or orange color.
MAIN BURNER
Periodically inspect all burner ame holes with the
heater running. All slotted burner ame holes should
be open with yellow ame present. All round burner
ame holes should be open with a small blue ame
present. Some burner ame holes may become
blocked by debris or rust, with no ame present. If
so, turn off heater and let cool. Remove blockage.
Blocked burner ame holes may create soot.
Figure 36 shows correct front burner ame pat-
tern. Figure 38 shows incorrect front burner ame
pattern. The incorrect burner ame pattern shows
yellow tipping at top of blue ame.
If front burner ame pattern is incorrect, as
shown in Figure 37
• turn replace off (see To Turn Off Gas to Ap-
pliance, page 20 or 22, depending on your
model.)
• see Troubleshooting, page 27
