Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 37 shows a correct pilot flame pat-
tern. Figure 38 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 38
• turn heater off (see To Turn Off Gas to
Appliance, page 17)
• see Troubleshooting, pages 20 through 22

INSPECTING
BURNERS
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the
holes in the fitting at the burner entrance.
These holes may become blocked with dust
or lint. Periodically inspect these holes for
any blockage and clean if needed. Blocked
air holes will create soot.
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 be-
come blocked by debris or rust, with no flame
present. If so, turn off heater and let cool.
Either remove blockage or replace burner.
Blocked burner flame holes will create soot.

2b. Press the AUTO/ON/OFF button on
the hand-held remote control (see Fig-
ure 36). The lights to the left of the
button will show AUTO, ON, or OFF.
• In the ON mode, the burners will
ignite. The heater is in manual
mode when ON is lit.
• In the AUTO mode, the thermostat
in the hand-held remote unit con-
trols the room temperature. To in-
crease the room temperature, press
the top arrow of the TEMP button.
To lower the room temperature,
press the bottom arrow of the
TEMP button. At higher settings
the heater will run longer.
IMPORTANT: This remote control
has been specially engineered to take
an air temperature sample every 5.5
minutes in the auto mode. It will not
respond immediately to the tempera-
ture setting being turned up or down.
IMPORTANT: The hand-held re-
mote control unit must be near the
heater. Do not keep the hand-held
remote control unit too close to the
heater. The thermostat on the hand-
held remote control unit will heat up
too quickly and turn the heater off.
3. To turn the burner off, press the
AUTO/ON/OFF button until OFF
lights. The pilot will remain lit.
IMPORTANT: To turn the pilot off,
manually turn the control knob on the
heater to the OFF position.
BURNER FLAME PATTERN

tern. Figure 40 shows an incorrect burner
flame pattern. If burner flame pattern is
incorrect,
