Air Shutter Settings for Broiler Burner
1. Use a screwdriver to loosen the air shutter screw.
2. Adjust the air shutters for NAT gas by rotating the shutter to
the fully open position. Your final settings may vary.
3. Retighten the air shutter screw.
Bake and broiler flame must be checked with the door closed to
properly check flame characteristics.
4. Turn on the gas.
5. Turn on the electricity.
6. Retighten the air shutter screw.
7. Turn on the bake and broiler burner.
8. As you watch the flame with the oven door closed, check the
following through the oven door window:
a. If the flames are yellow, open the air shutter more.
b. If the flames blow away or flutter from the burner, close
the air shutter more.
9. Open the oven door and check the inner cone of the bake
and broiler burner flame. It should be approximately 1/2” to
3/4” long for the bake and broil burners. The combustion
quality of the burner flames needs to be determined visually.
10. When all adjustments are made and the results are
satisfactory then replace the oven bottom cover.
In some cases, foreign particles in the gas line may cause an
orange flame at first but this will soon disappear.
Note: To convert the oven back to LP gas, reverse the instructions
given for making the NAT gas adjustments.
Note: When the NAT conversion is finished, complete the
enclosed conversion label and place it next to the rating label.
