INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 37 shows a correct pilot flame pattern.
Figure 38 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not touch-
ing the thermocouple. This will cause the
thermocouple to cool. When the thermo-
couple 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 16)
• see Troubleshooting, pages 19 through 21

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.
CGHRCTA Series Operation:
2b. Press the AUTO/ON/OFF button on
the hand-held remote control (see
Figure 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 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.
