TO TURN OFF GAS
TO APPLIANCE
Shutting Off Heater
Turn control knob clockwise to the
OFF position.
Shutting Off Burners Only (pilot stays lit)
Turn control knob clockwise
to the
PILOT position.
THERMOSTAT CONTROL
OPERATION
The thermostat control knob can be set to any
comfort level between HI and LO. The ther
-
mostat will gradually modulate the heat output
and flame height from higher to lower settings
or pilot, in order to maintain the comfort level
you select. The ideal comfort setting will vary
by household depending upon the amount of
space to be heated, the output of the central
heating system, etc.
Note: Selecting the HI setting with the control
knob will cause the burner to remain fully on,
without modulating down in most cases.
MANUAL LIGHTING
PROCEDURE
1. Follow steps 1 through 5 under Lighting
Instructions, page 13.
2. Depress control knob and light pilot with
match.
3. Keep control knob pressed in for 30 seconds
after lighting pilot. After 30 seconds, release
control knob. Now follow step 8 in Lighting
Instructions, page 13.
INSPECTING BURNERS
Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 18 shows a correct pilot flame pattern.
Figure 19 shows an incorrect pilot flame pattern.
The incorrect pilot flame is not touching the
thermocouple. This will cause the thermocouple
to cool. When the thermocouple cools, the heater
will shut down.
If pilot flame pattern is incorrect, as shown in
Figure 19
turn heater off (see To Turn Off Gas to
Appliance
)

CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep con-
trol areas, burner and circulating
air passageways of heater clean.
Inspect these areas of heater
before each use. Have heater
inspected yearly by a qualified
service person. Heater may need
more frequent cleaning due to
excessive lint from carpeting, pet
hair, bedding material, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clear may result in
sooting and property damage.
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.
