CONNECTING UNIT TO GAS/MAIN BURNER ADJUSTMENT
CONNECT UNIT TO GAS
1. Each unit is factory equipped for use with the type of
gas indicated on the range rating plate located on the
lower panel. Check type of gas supply available.
NOTE:
A. Pipe joint compounds used when connecting
appliances to gas should resist the action of L.P.
gases.
B. Pipe joints should be tested for leaks with a soap and
water solution before operating the unit. Do not use
matches or flame to test.
C. Standard units for use on natural or mixed gases are
equipped with fixed orifices and a pressure regulator
with a preset outlet pressure of 3.7" W.C. Units for
use on propane gas are equipped with fixed orifices
and pressure regulator with preset outlet pressure of
10.0" W.C.
2. When connecting the oven to the gas supply, the pres-
sure regulator must be mounted vertically as shown in
Detail A2 to insure the proper preset outlet pressure.
If the regulator is mounted in any other position, the
outlet pressure must be reset.
NOTE:
The unit and its individual shut-off valve must be disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in
excess of 1/2 psig (3.45 L PA.) The appliance must also
be isolated
from the gas supply piping system by closing its
individual manual shut-off valves during any pressure
testing of the gas supply piping system at test pressures
equal to or less than 1/2 psig (3.45 L PA.) as stated by
the American National standards Z83.11-1986. Copies of
this standard are available from the American Gas
Association, 1515 Wilson Blvd., Arlington, VA 22209.
NOTE:
Do not obstruct the leak limiter on the gas pressure regulator.
3. MAIN BURNER ADJUSTMENT
Standard units, equipped with a pressure regulator and
fixed orifices, have been adjusted at the factory and
should require no further adjustment. The efficiency of
the oven depends on a rather delicate balance between
the supply of air and volume of gas so that complete
combustion is achieved. Whenever this balance is
disturbed, poor operating characteristics and excessive
gas consumption occur.
AIR SUPPLY is controlled by an air shutter on the front
of the burner. The air shutter openings should be increased until the flame on the burner begins to "lift". The
air shutter should then be closed slightly and locked in
place. A yellow streaming flame is an indication of insufficient air. This condition can be corrected by increasing
the air shutter opening.
