Bake Burner Adjustment

The appearance of a properly adjusted gas flame is one
having an inner core of bluish-green and an outer mantle
of dark blue. The length of the inner cone on the flame
will be about 3/8" when correctly adjusted. Flame
characteristics should be clean but soft.

To adjust the bake burner air shutter:
1. Remove storage drawer to gain access to air shutter.
2. Remove oven bottom to observe burner flame.
3. Turn oven on to 350°F setting.
4. Loosen air shutter retaining screw and adjust shutter
to provide an air opening of approximately 3/8" or to
provide a burner flame as shown above.
5. After adjustment is complete, tighten shutter retaining
screw and replace oven bottom and storage drawer.

To avoid possible electrical shock, personal injury, or death,
disconnect power and turn off gas supply before servicing,
unless testing requires it.

Gas Pressure and Measurement

Equipment for measurement of gas pressure varies from
pressure meters and gauges to the relatively simple and
most commonly used manometer. If a pressure gauge
or meter other than a manometer is used, follow the
directions supplied with the unit. The following
information covers the use of a manometer.
A manometer is simply a u-shaped tube of clear plastic
or glass. A scale in inches is located between the two
legs of the U. In use, the tube is filled with sufficient
water to achieve a level at "0" inches. One end of the
tube is then connected to the range manifold or gas
valve orifice while the other end of the tube or leg is
open. When gas pressure is applied, the water on the
gas side of the tube is pushed down and the water in the
other rises up against the atmospheric pressure on the
open end. The sum of the readings below the zero level
and above the level will provide the gas pressure in
inches water column, or the water column height which
the gas pressure will support against the atmospheric
pressure on the top of the water column. The
manometer therefore indicates gas pressure in inches
water column. This conforms with the gas specifications
for gas appliances which are given as inches WCP or
inches water column pressure.
The example below shows four inches WCP, (two inches
above and two inches below the zero level).
