OPERATION

Pilot Lighting Instructions

1 . The in-line service shut-off valve should be in the "ON"
position .
2 . With a lighted taper you can now light the pilots which
are located at the rear of the main burner .
3 . The Pilot flame should be approximately 7/8" long for
proper ignition of the burners . The pilot adjustment
valve can be located by sliding the drip tray forward .
Adjustment valves are located on the manifold pipe
which runs horizontally across the back of the unit,
behind the drip tray . One valve is at the left rear and the
other at the right rear .
To adjust the pilot light, turn the brass screw counter-
clock-wise to increase the pilot flame, and clock-wise to
decrease the pilot flame .
NOTE: No more than 7/8" pilot flame length should be
required . Too high a setting will cause the flame to lift off or
will create excessive carbon deposits . Do not adjust the pilot
flame lower than 7/8" long because this can cause delayed
ignition at the burner . The delayed ignition could cause the
burner tiles to crack; in that case the burner would have to be
replaced .

Main Burner Operation

Turn main burner knob to the "MAX" position and
immediately check ignition .
CAUTION Should ignition fail after five seconds, turn valve
off and wait five minutes before trying again . Pilot gas is
not interrupted automatically . It is the responsibility of the
operator to check the ignition of burners immediately after
the burner valve has been turned on .
When ignition has been accomplished, a blue flame will
cover the surface of the ceramics for 10-15 seconds . The haze
will disappear and the burner rod will glow red . After the
burners have operated for several minutes turn the valve to
"MIN . " The burner rods will no longer glow red and the flame
travels back and forth on the face of the burner ceramics .

Burn off Period

Many parts used in the manufacturing of commercial
equipment have a thin, protective coating of machine oil .
This oil should be burned off before the equipment is used
for food preparation .
Part # 4523974 Rev 1 (09/03/09)
After all start-up and safety checks have been completed,
turn burner valve to the "MAX" position . Smoke (a bluish
haze) will be produced . This process can take several hours
and can be completed over a few days .

Energy Conservation

Do not waste energy by leaving controls at high temperature
settings during idle periods . Lower settings will keep broiler
warm and ready for next use period . Reset burner valve knob
as required for heavy load periods .

Shut Down Instructions

Turn main burner valve knobs to the "OFF" position . If the
unit is to be shut down for an extended period of time, close
the manual in-line service valve (manual in-line service valve
is not factory supplied) .
FOR YOUR SAFETY never place any type of object on top of
the salamander broiler . The top of the broiler will exceed
1000° F . It could cause severe burns and/or fire and also
will obstruct ventilation .

Main Burner Adjustments

All salamanders are provided with fixed burner orifices to
provide 20,000 BTU/HR at the "MAX" setting on Natural
Gas supplied at 6 .0" WC (15 Mbar) pressure or propane gas
supplied at 10 .0" WC (25 Mbars) pressure .
The "MIN" setting is adjustable and should be set as follows:
1 . Set the burner valve knob to "MIN" setting and remove
the knob .
2 . Insert a thin bladed screwdriver into the valve stem
to engage the slot inside the stem . Turn clockwise to
decrease the rate and counter-clockwise to increase .
Proper adjustment is attained at the point where the burner
rods no longer glow and the flame travels back and forth on
the face of the ceramics .
This adjustment has been factory pre-set, however, with
changing pressures this adjustment and pilot adjustment
may need to be re-done after installation .
This is not considered a manufacturing defect and is not
warrantable .
NOTE: Burner adjustments should only be done by an
authorized service technician .
