WARNING
During operation there is an open flame inside this appliance. The unit may get hot
enough to set near by materials on fire. Keep the area around the appliance free from
combustibles.
Lighting Instructions
For manual pilots, refer to the following instructions.
WARNING
If pilot extinguishes, wait 5 minutes before attempting to relight the pilot to allow any built
up gas to dissipate.
a. Open gas supply valves to the appliance.
b. Turn the thermostat control knob counterclockwise to the OFF position.
c.
Turn the gas valve knob counterclockwise to the PILOT position. Push knob in
and hold a flame to the pilot until the pilot ignites; this may take a little while
the first time you light the pilot because of the air in the lines. Once lit, hold
the knob in for approximately one minute and then release.
d. If the pilot goes out, wait 5 minutes and repeat step C. If after three tries the
pilot will not remain lit, refer to the operator troubleshooting section of this
manual.
e. Once a pilot flame has been established, turn the gas valve knob
counterclockwise to the ON position.
f. Set the thermostat control knob to the desired temperature setting, The main
burners will ignite and be controlled by the thermostat.
Pilot Flame Adjustment
For manual pilots, refer to the following instructions. Perform this procedure once the pilot is lit and
ensure that the thermostat is turned to the OFF position.
NOTE: This procedure requires a DC millivolt meter set to a scale of 0-1000 mV.
Using test leads with sharp probes will help in taking the required readings.
a. Locate the thermopile wires coming from the pilot to the
gas valve.
b. Using the positive (+) test probe, connect the probe to
the top PP terminal with the red wire.
c. Connect the negative (-) test probe to the bottom PP
terminal with the white wire.
d. The output level should be 550mv ± 50mV. If this level
is not correct, remove the cap screw and adjust the
screw in and out to achieve the proper millivolt level.
Replace cap screw.
Note: Allow 3 to 5 minutes between flame adjustments to allow the reading to stabilize.
