IMPORTANT: This remote control
has been specially engineered to take
an air temperature sample every 5.5
minutes in the auto mode. It will not
respond immediately to the tempera-
ture 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 re-
mote control unit will heat up too
quickly and turn the heater off.

OWNER'S MANUAL
INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.

PILOT FLAME PATTERN

Figure 35 shows a correct pilot flame pat-
tern. Figure 36 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 36
• 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.
