PILOT ADJUSTMENT:
Begin by lighting up the Pilot according the procedure explained on Page 16:
•
Push and turn the gas control knob to the
PILOT position.
•
Push the ignition (spark) button.
•
Push the Gas Control Knob
The Pilot should lit instantly. Continue hold-
ing the gas knob for at least 5 ~ 10 seconds
and release the gas control knob.
The Pilot should remain lit. If the Pilot does
not remain lit, adjustment might be neces-
sary. This procedure will apply to both the
Hearth Stone IR Burner as well as the Log
burner.
The Pilot is equipped with a Thermocouple designed to sense the presence of a flame and relay this in-
formation to the gas valve. If the Thermocouple does not sense the flame, the valve will cut of the flow
of gas to the Pilot and the Burner as a safety measure.
Light the Pilot again and using a small flat blade screwdriver, adjust the Pilot flame size to approximately
1” to 1½” in overall length. (See Figure # 11 on page 17 and Figure # 12 on this page)
TURN CLOCKWISE
►
LESS FLAME
TURN COUNTER-CLOCKWISE ► MORE FLAME
If the flame is too small the Pilot will not remain lit when you release the knob, readjust to a longer
flame.
LOW HEAT SETTING ADJUSTMENT (LOG BURNER):
NOTE:
THE LOW HEAT SETTING ON YOUR OVEN IS PRESET AT THE FACTORY. ADJUST ONLY IF ALTI-
TUDE OR ENVIRONMENTAL FACTORS ARE CAUSING POOR, LOW HEAT, PERFORMANCE.
ADJUSTMENT STEPS:
1. Follow lighting instructions and set the control knob
on “HI” and allow the burner to preheat for 5
minutes.
2. Turn the control knob to “LOW” and wait for the
burner temperature to drop and stabilize.
3. Insert a small blade screwdriver into the LOW SET-
TING screw of the valve to begin the adjustment.
4. Turn counter-clockwise to INCREASE the low heat
flame, Clockwise to DECREASE.
5. Adjust the flames so the burner flame is approxi-
mately 1½” to 2” in length in the LOW position.
