INITIAL OPERATION CHFXKr
Models 17OA, 171A, 27OA,
17OD,
171D, 270D
The suffix aA" indicates that a centrifugal switch within the motor controls a gas solenoid. The unit
can not be operated without power to the unit.
The s&ix "D" indicates that there is no centrifugal switch or gas solenoid valve. These units employ
the Southbend exclusive burners which can operate with or without the blower. For optimum
performance, however, the blower should be on.
I.
When all gas and electrical connections have been checked out, proceed as follows to put the
unit into operation:
A.
B.
C.
Turn broiler burner valve to "OFF."
Turn blower switch to "OFF."
Turn on the main gas supply.
D.
E.
F.
Turn on manual service valve located on inlet supply line in the blower compartment.
SufRx "A" models have a pair of burners and each have a pilot at its front. Light these 3
pilots. These pilots are controlled by a small valve located behind the plug button, just below
the left burner valve. The pilot flame should be 3/4" high, adjust if necessary.
For suffix "D" models, each burner has a pilot at its front. Light these 3 pilots. These pilots
are controlled by a small valve located behind the plug button. This button will be located in
the very center at the top of the unit. The pilot flame should be 3/4" high; adjust if
necessary.
These pilots should burn continuously unless the broiler is to be completely shut down. When
extinguished the pilot gas supply is NOT INTERRUPTED automatically. For complete shut
down the large manual service valve on the inlet gas supply line, referred to in I.(D) above,
must be turned to "OFF."
II. Press the blower switch to 'ON."
A. For "A" sufbx units:
1. The motor (blower) will start.
2. As it accelerates, its centrifugal switch will close.
3. This allows current to flow to the gas solenoid and the indicator light.
4. When the gas solenoid is energized, it opens, allowing gas to flow to the main burner
valves.
5. When the red light glows it indicates that the gas solenoid is 'OPEN."
B. For "D" suffix units:
1. The motor (blower) and red indicator light will be energized immediately. The electrical
circuitry does not control the gas.
2. Gas is always available to the main burner valves, even with the motor off.
NOTE: Should an odor of gas be detected, check for leaks on all fittings within the blower
compartment, using the soapy water method. NEVER USE A FLAME.
III. Turn the broiler valve to HIGH. As each valve is opened, immediately check ignition of burners.
When the burners ignite, a blue flame will cover the surface of the ceramics for lo-15 seconds.
This haze will disappear and within 30 seconds the ceramics will glow red. The flame on the
surface of the ceramics should be barely visible, with practically no blue haze. Should this con-
dition not be obtained, it may be necessary to regulate the air supply to the manifold compart-
ment. This air is supplied by a blower, with a shutter for regulation. There is NO primary air
adjustment on the burner itself. (See ADJUSTMENTS)
