instructions.
2. Check to ensure there are no gas leaks. If you are unsure,
turn gas off to the heater and call a service person or your gas
utility.
Clothing or other flammable material should not be placed
on or near the appliance.
Children and adults should be alerted to the hazard of high
surface temperature and should stay away to avoid burns
or clothing ignition. Young children should be carefully
supervised when they are in the same room as the appliance.
3. Tampering is DANGEROUS and voids all warranties. Any
component that is found to be faulty, must be replaced with an
approved component.
Initial Lighting
Upon completing the gas line or turning the gas valve "ON" after it
has been in the "OFF" position, a small amount of air will be in the
lines. When first lighting the appliance, it will take a few minutes
for the lines to purge themselves of this air. Once the purging is
complete, the appliance will light and operate satisfactorily.
Subsequent lightings of the appliance will not require such purging
if the gas valve is not turned to "OFF."

Standing Pilot Operation
1. Follow the SAFETY and LIGHTING INSTRUCTIONS for standing
pilot controls found in this manual and on labels found attached
to the appliance.
During the initial purging and subsequent lightings, never
allow the gas valve control knob to remain depressed in the
"pilot" position without pushing the piezo ignitor button at
least once every second.
2. During the heating season, leave the control valve knob in the
"ON" position. This will allow the pilot flame to remain lit. Turn
the burner flame on or off with the appliance REMOTE/OFF/ON
rocker switch, wall switch, remote control kits or 750 millivolt wall
thermostat.
NOTICE: The gas control valve allows you to increase or decrease
the height of the main burner flame. The control valve has a pressure
regulator with a knob as shown in Figure 9. Rotate the knob clockwise
to "HI" to increase the flame height and counterclockwise to "LO"
to decrease the flame height.
3. When the heating season is over, turn the REMOTE/OFF/ON
switch to "OFF" and the control valve to "OFF". The system,
including the pilot light, will be shut down.
Maximum and Minimum Input
The gas valve on the appliance allows the input to adjust between
a maximum input of 25,000 Btuh to a minimum input of 17,500
Btuh. Please be advised, the maximum input provides the greatest
amount of yellow flame and ember glow on the log set. The minimum
input substantially decreases the yellow flame and ember glow on
the log set.
