2b. Press the AUTO/ON/OFF button on the hand-held remote
control (see Figure 26). 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 re-
mote unit controls the room temperature. To increase the
room temperature, press the top arrow of the TEMP but-
ton. 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 en-
gineered to take an air temperature sample every 5.5
minutes in the AUTO mode. It will not respond immedi-
ately to the temperature 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 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 con-
trol knob on the heater to the OFF position.

INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
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
touching the thermocouple. When the thermocouple 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
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.
