3. Turn the control knob to “MIN” and wait for the burner temperature to drop and stabilize.
4. Insert a small blade screwdriver into the LOW SETTING screw of the gas valve to begin the
Hearth Burner adjustment.
5. Turn counter-clockwise to INCREASE the low heat flame, Clockwise to DECREASE.
6. Adjust the flames so the burner flame looks BLUE in color and is stable without empty areas
around the perimeter of the burner (See
Figure # 13
)
7. The flame should be between 1/8” and 3/16” in height when properly adjusted.
8. The door opening, door threshold and the cavity in general, will be hot after this adjustment. Let
the entire oven cool down to the touch before replacing the Hearth Stone removed in step 1.
9. Reattach the knobs by pushing them onto the stems of the gas valves.
The automatic burner igniter system will continue to glow even when the burner is at it’s lowest setting.
The hot surface igniter will continue glowing as a safety measure, while allowing the safety gas valves
to remain open flowing gas to the burner.
NOTE:
The Air Shutter (air mixer) on the Heart Stone Burner is already preset from the factory for your units’
fuel requirement (NG or LP). In high altitude conditions, there could there be poor combustion and soot
forming around the burner ports. If that is your situation, simply adjust the air-shutter by loosening the
set screw (underside of the burner) and open just slightly for a better air-mix. The flame should only be
slightly yellow at the base ports and have blue tips. The air shutter gap should be between 1/8” to 3/8”
maximum depending on your fuel.
