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 patterns often.
PILOT FLAME PATTERN
Figure 34 shows a correct pilot flame pattern. Figure 35, shows an
incorrect pilot flame pattern. The incorrect pilot flame is not
properly heating the thermocouple. When the thermocouple cools,
the heater will shut down. If pilot flame pattern is incorrect, as
shown in Figure 35
• turn heater off (see To Turn Off Gas to Appliance, page 16)
• see Troubleshooting, pages 20 through 22
Note:
The pilot flame on natural gas units will have a slight curve,
but the flame should be blue and have no yellow or orange color.

Auto (Thermostatic) Mode
1.
Press the POWER and LOCK buttons together to turn on
the hand-held remote control.
2.
Press AUTO button to select this mode.
3.
Set the desired room temperature by pressing the TEMP
+ or - buttons.
4.
Press the POWER and LOCK buttons together to turn off
the fireplace
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 fire-
place, the receiver ON/OFF/REMOTE switch should be in the
OFF position.
Auto Shutoff Feature
1.
If the average room temperature exceeds 82 degrees Fahr-
enheit (28 degrees Centigrade), the hand-held remote con-
trol 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.
