Figure 26 - Incorrect Pilot Flame Pattern
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 properly heating the thermocouple.
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 17 through 19

INSPECTING
BURNERS
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 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.
Thermocouple
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 the
heater. The thermostat on the hand-
held remote control unit will heat up
too quickly and turn the heater off.
3. Use the STATUS button on the hand-
held remote control unit to see the
operation mode being used and the
temperature setting selected. A red
light will come on beside the opera-
tion mode being used when the sta-
tus button is pressed.
4. To turn the burner off when operating
in the manual mode, press the OFF
button. If operating in the auto mode,
press the MAN button, then press the
OFF button. The pilot will remain lit.
IMPORTANT:
To turn the pilot off,
manually turn the control knob on the
heater to the OFF position.
