INSTRUCTIONS
NOTICE: During initial operation
of new heater, burning logs will
give off a paper-burning smell.
Orange flame will also be present.
Open damper or window to vent
smell. This will only last a few hours.

STOP! Read the safety information
on page 15.
2. Make sure manual shutoff valve is
fully open.
3.
Turn control knob clockwise
to the OFF position.

Wait five (5) minutes to clear out any
gas. Then smell for gas, including

Note: You may be running this
heater for the first time after hook-
ing up to gas supply. If so, the con-
trol knob may need to be pressed in
for 30 seconds or less. This will allow
air to bleed from the gas system.
• If control knob does not pop out when
released, contact a qualified service
person or gas supplier for repairs.

With control knob pressed in, press
and release ignitor button. This will

Note: If pilot does not stay lit, contact
a qualified service person or gas sup-
plier for repairs. Until repairs are made,
light pilot with match. To light pilot with
match, see Manual Lighting Procedure.

Shutting Off Burners Only (pilot
stays lit)
Turn control knob clockwise

THERMOSTAT
CONTROL OPERATION
The thermostat control knob can be set to
any comfort level between Hi and Lo. The
thermostat 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.

BURNERS
Pilot Burner
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 29 shows a correct pilot flame pattern.
Figure 30 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not prop-
erly heating 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 30
• turn heater off (see To Turn Off Gas to
