PILOT FLAME PATTERN
Figure 27 shows a correct pilot flame pattern.
Figure 28 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not touch-
ing the thermocouple. When the thermo-
couple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 28
• 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 ev-
ery 5.5 minutes in the AUTO mode.
It will not respond immediately to
the temperature 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.
