INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 25 shows a correct pilot flame pat-
tern. Figure 26 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 26
• turn heater off (see To Turn Off Gas to
Appliance, page 15)
• see Troubleshooting, pages 18 through 20

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 remote
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 re-
mote 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.
