OVEN TUBULAR GAS BURNER ADJUSTMENT (See Illustration #1)
Check the gas supply, and set the regulator to proper supply of gas. A properly adjusted burner should be stable and
quiet. The flame should have a sharp, well defined blue inner cone with no yellow tipping. The flame should also be
stable and uniform with no flames lifting off the burner ports.
To gain access to the oven burner adjustments:
1. Remove oven bottom panel.
2. Remove U-shaped burner venturi cover.
3. Locate the air shutter and loosen the set screw that holds the air shutter in place.
4. Light the burners by rotating the thermostat to a baking temperature.
5. Using a 1/2" (1.3 cm) open-end wrench, adjust orifice hood to obtain a sharp, well defined blue inner cone
approximately 1/2" (1.3 cm) long. The flame should be contacting the burner at each port opening. THE FLAME
SHOULD NOT EXTEND INTO THE OVEN BOTTOM VENT SLOTS.
6. With a proper flame height, adjust the air shutter to obtain a blue flame with no yellow tipping that contacts the
burner at the burner ports.

to prevent a noisy flame
that lifts off the burner.

adjustment for proper gas
flow.

screw being careful to not
change the adjusted
