ADJUSTMENTS
Burner Adjustments – All Units
1. Before making any adjustment, turn all gas valves
to “OFF”. Remove the burner tie wires, if not already
removed. Be sure all piping is gas tight and that air is
purged from lines.
2. All units are shipped from factory at burner ratings set
for the gas specified on the rating plate at normal gas
pressure. The only adjustment necessary is for that
governing air.
Air Adjustment: If necessary, the air is adjusted by rotating
the air shutter on burner. The burner must have enough air
that the tips of the flames are not yellow, but not so much air
that the flames will lift off the burner ports. Securely tighten
air shutter screw so air shutter cannot be moved.
Hot Plates
IMPORTANT: The flue must be installed prior to start-up.
Pilot Burner Adjustment
Each burner in the hot plate is equipped with a pilot. The
burner pilot is ignited by the piezo ignitor located behind the
front door.
The pilot has been adjusted at the factory; however, it may
require adjustments once installed. The pilot adjusting valve
is located under each burner valve.
Open the bottom door and use a long thin straight blade
screwdriver to adjust the valve. Refer to Flame Size Chart.
Burner Operation
The burner will light automatically from the pilot. Turn the
valve to the full “ON” position. Once the flame has ignited,
adjust the valve to the desired setting.
Fryers
Before Operating the Fryer
1. Before leaving the factory, the fryer was tested and the
thermostat calibrated with oil in the fry tank; therefore, it
is necessary to clean the fry tank before filling with frying
compound. Use detergent or other cleaning agents, with
hot water. Thoroughly rinse and dry fry tank.
2. BEFORE LIGHTING THE PILOT, fill the fry tank. NEVER
OPERATE THE PILOT OR BURNER WITH AN EMPTY FRY
TANK. It only takes a few minutes to completely ruin a fry
tank and void the warranty.
3. WARNING: When fryers are in use, fryer restraint chains/
cables must be installed in order to prevent the fryer from
tipping and splashing hot liquid. Hot shortening causes
severe burns. Never attempt to move a fryer when the
frypot is full. Drain frypot completely before moving fryer.
Pilot Burner Adjustment
1. Turn thermostat knob to lowest position.
2. Depress and turn automatic gas valve knob to “OFF”
position. Caution: Wait 5 minutes before lighting or
relighting pilot.
3. Turn automatic gas valve knob to “Pilot” position.
4. Push knob in, light pilot, and continue to hold knob in for
about 60 seconds after pilot light is lit.
5. Adjust pilot flame to 3/4” (19 mm).
6. If pilot does not continue to burn after releasing button,
repeat above procedure or…
7. Have a qualified Serviceman check the system. DO NOT
ALLOW ANYONE ELSE TO ATTEMPT REPAIRS.
To Operate Main Burner
1. If liquid frying compound is used, the main burner may
be turned on.
2. To ignite burner, turn automatic gas valve
counterclockwise to the “ON” position.
3. If a Hydrogenated (SOLID) frying compound is used,
pack the tank with compound and turn the main burner
on for approximately five seconds and turn it off for
approximately ten seconds. Repeat until compound
is melted. If any smoke is seen during the process, the
heating action is being carried out too fast and the
frying compound is being scorched as well as possibly
damaging the fry tank.
