INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 23 shows a correct pilot flame pattern.
Figure 24 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 24
• turn heater off (see To Turn Off Gas to
Appliance, page 15)
• see Troubleshooting, pages 17 through 19
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.

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 become blocked by
debris or rust, with no flame present. If so, turn
off heater and let cool. Remove blockage.
Blocked burner flame holes will create soot.

(GHRCTA Series Only)
GHRCTA Series Operation:
2b. Press the AUTO/ON/OFF button on
the hand-held remote control (see
Figure 22, page 17). 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.
IMPORTANT:
To turn the pilot off,
manually turn the control knob on the
heater to the OFF position.
