Electronic Ignition System
Certain procedures in
this section require electrical test or
measurements while power is applied
to the machine. Exercise extreme
caution at all times and follow Arc Flash
procedures. If test points are not easily
accessible, disconnect power and
follow Lockout/Tagout procedures,
attach test equipment and reapply
power to test.
1. Access burner electrode.
2. Remove ignition wire from burner electrode.
3. Fasten metal end of ignition wire about ¼ away
from a grounded metal surface on fryer.
4. Try to light the burner.
5. You should be able to see a spark. If no spark,
check ignition module in power supply box.
MODULATING GAS VALVE
ADJUSTMENTS
Disconnect the
electrical power to the machine and
follow lockout / tagout procedures.
Shut off the gas before servicing the
unit.
All gas joints disturbed during
servicing must be checked for leaks. Check with a
soap and water solution (bubbles). Do not use an open
flame.
The modulating gas valve is adjusted at the factory
and requires no adjustments. If the modulating gas
valve needs to be replaced, the new gas valve from
the parts depot will be adjusted property and will only
need to have the gas pressure verified coming into the
gas valve.
All fryers built after 12/1/12 will have gas regulators
installed on the incoming gas line. The gas pressure
on the new gas vales will not have to be checked.
BASKET LIFT ARM ADJUSTMENT
1. With shortening at room temperature, verify the
shortening level is between MIN & MAX lines in
fry tank. Add shortening as needed.
NOTE: Shortening will expand when heated. Do not
fill the fry tank past the MAX line.
2. Turn power switch on and set temperature to
350°F. Allow the shortening to reach set
temperature.
3. Check basket lift operation.
A. If necessary, adjust as outlined below.
4. When basket is in the up position, the bottom of
the basket should be out of the shortening. When
basket is in the down position, the bottom of the
basket should clear the crumb screen and the
product should be submerged.
A. To adjust, remove basket arm from lift shaft,
loosen stop nut and turn height adjustment
bolt to raise or lower basket arm as required.
Both baskets should be same height.
B. Tighten stop nut when complete.
NOTE: If adjustment is to low, when the basket is
lowered, it will disengage from basket arm
