Inspecting Burners - Desa R series Owner's Manual

OPERATING HEATER
Continued
Note: Do not leave the hand-held remote in the
AUTO mode close to the fireplace. The radiant
heat from the fireplace will turn off the fireplace.
Ideally, place the hand-held remote in the center
of the room facing towards the fireplace.
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 fireplace, 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 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. This will occur in 8
or more minutes depending upon location of
remote transmitter and strength of batteries.

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.

INSPECTING bURNERS

Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 39 shows a correct pilot flame pattern.
Figure 40 shows an incorrect pilot flame 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 flame pattern is incorrect, as shown in
Figure 40
• turn heater off (see To Turn Off Gas to Appli-
ance, page 20 [Thermostat-Controlled Models],
page 22 [Manually-Controlled Models] or page
24 [Remote-Ready Models])
• see Troubleshooting, page 29
Note: The pilot flame on natural gas units will
have a slight curve, but flame should be blue and
have no yellow or orange color.
