Manual HI-LO Control Knob
Fig. # 15
OPERATION
The heater comes equipped with an "ON-OFF" rocker switch.
This switch is conveniently located on the control panel just
behind the access door.
Once a pilot light has been established, and the gas valve
knob turned to the "ON" position, the burner may be turned on
or off simply with the switch. An optional wall thermostat may
be installed to operate the burner automatically.
Manual HI-LO Flame Adjustment:
The HI-LO burner control knob can be rotated in both
directions, providing infinite control of gas flow rate to the
burner and therefore greater comfort control. The HI
setting provides a maximum gas input (flame height), and
rotating the knob clockwise toward the LO setting will
reduce the gas input (flame height) to a minimum setting.
Wall Thermostat (optional part# GASC.THERMO):
Set the wall thermostat to a comfortable temperature. Turn
the HI-LO burner control knob to a desired setting. As heat
is required, the heater will turn on or off automatically, as
needed.
Extend Shutdown:
To shutdown the appliance including the pilot, partially
depress and turn gas valve knob clockwise past “PILOT”
to “OFF” position. DO NOT FORCE.
NOTE: The SIT control has an interlock device which does not
allow the pilot to be lit when the appliance is at operating
temperature. Let the appliance cool down (approx. 60 sec.)
before attempting to relight the pilot. DO NOT use force to
rotate the control knob.
PRIMARY AIR ADJUSTMENT
This appliance is provided with primary air adjustment, which
affects flame height and quality.
Adjustment is possible to compensate for varying field
conditions, such as vent system configuration or altitude.
Adjustment should be done after the appliance has reached
operating temperature.
Caution! Firebox may be hot.
The air shutter adjustment rod is located behind the control
panel, to the left of the gas valve, (see fig #17). Pulling the rod
down opens the shutter and decreases the flame height.
Pushing the rod up closes the shutter and increases the flame
height.
To Adjust:
1)
With appliance at operating temperature, open control
door to access control panel.
2)
Pull control knob extensions off.
3)
Remove the two screws at the top edge of the control
panel and remove panel to gain access to the adjustment
rod. Depressing the igniter while moving the control
panel may be necessary on units with the pedestal
option.
4)
Move air shutter adjustment rod up or down until proper
flame is obtained.
5)
Reassemble control panel.

Caution: Proper air shutter setting is a must.
The flame should be just yellow, “lazy” and just below the
baffle. It should NEVER be set to create sooting on internal
parts and glass. Open air shutter gradually until sooting stops.
