Chapter 1: HOW DOES IT WORK?
The McDonalds Gas II fryer components function in
specific order of operation. Knowing and understanding
the sequence of fryer and components operation will
enable you to diagnose equipment failure more
accurately.
Heating System
Power to the machine is turned ON:
• If Fuse F1 on the Relay board is good, the A.C.
indicator will illuminate and the controller will be
supplied with 24 VAC and, if the drain valve handle
is closed, the proximity switch will supply 24 VAC
to the DVI (drain valve interlock) input at the
controller.
• The computer control is turned ON:
• The side on relay will be energized, closing the
circuit and the S.O. indicator on the Relay Board
will illuminate. If the hi limit is NOT tripped the
ignition module will receive 24VAC at terminal 6 (24
VAC).
• The ignition module will have a 24 VAC output from
terminal 3(PV) to the PV terminal on the gas valve
and the ignitor will spark. When the pilot has lit and
the module has proven the pilot flame, it will have a
24 VAC output at terminal 1(MV) and put 24 VAC
on pin #2 at connection J/P32 on the relay board.
The heat demand relay on the relay board will
interrupt the 24 VAC supply to the gas valve until
the controller calls for heat.
Note: When the controller is on, the pilot should
always remain lit.
• Controller calls for heat:
• The heat demand relay will energize supplying the
gas valve with 24 VAC and the H.D. indicator on
the Relay Board will illuminate. This will also supply
the computer with a heat feedback signal.
Hi Limit System:
• If the hi limit trips, it interupts the 24 VAC supply to
the ignition module. When the controller calls for
heat, it will not receive a 24 VAC heat feed back.
With approximately 90 seconds of heat feed back
loss, the controller will indicate an ignition failure or
heat failure.After the hi limit is reset (unit cools to
400°F + 20°F) the computer will have to be turned
off and back on for the unit to heat.
Hood Relay System: U.S./Canada units only
• There is one Hood Relay (K6) per "battery" of
fryers (located on rear bottom brace of left hand
fryer), it is wired in parallel to every computer
(both sides of a twin). When any side of any
computer is turned on this relay energizes
(turning on the hood) and will stay energized
until all of the computers are turned off.
Filter System:
• Opening the RED return valve handle will close
the proximity switch causing the "pump run" relay
to be energized. The pump motor will begin to
run.Closing the return valve handle will de-ener-
gize the relay and the pump motor will stop run-
ning.
• The pump system is equipped with a circuit breaker
which will de-energize the system and the heat tape
in the event of over current. The circuit breaker
switch must be in the ON position for the pump
and heat tape to operate.
• The return piping system may be equipped with
optional heat tape to prevent solidification of solid
shortening. The heat tape is low wattage and is on
constantly to maintain liquid shortening in the line.
Chapter 2: COMPONENT
TROUBLESHOOTING:
Probe:
The resistance of the probe will change as the tem-
perature changes. The resistance will decrease as the
temperature rises.
If the probe is suspect, check its resistance and the oil
temperature at which it was taken. Compare these
values on the probe resistance chart.
If the probe returns an open circuit or 0 Ohms read-
ing, it should be replaced. If the resistance varies more
than 30 Ohms when being checked between 325-
375°F the probe will give a false temperature reading
on the computer and should be calibrated (up to 10°F)
or replaced. However, it will continue to operate at a
slightly higher or lower temperature.
Allow the oil to cool and check the probe resistance

5L22-236 Rev 0 (04/03)
at a lower temperature. As can be seen from the chart a
greater variation can be tolerated at a lower tempera-
ture.
Gas Valve:
The gas valve has a dual 24 VAC operator and will
open when the correct voltage is supplied to the
operator. With 24 VAC applied to the PV (24 VAC)
connection, the pilot valve operator will open, allowing
gas to flow to the pilot.
With 24 VAC applied to the MV (24 VAC)
connection, the main valve operator will open,
allowing gas to flow to the main burners.
Hi Limit:
The hi - limit switch is a normally closed switch until
the temperature at the hi-limit bulb reaches 450°F ±
15°F.
WARNING!
This test should be performed by a qualified
technician only! Monitor the fryer closely. This
test will cause the oil to heat past the normal
operating temperature and can cause damage
to the machine and its operator if care is not
taken.
WARNING!
This test will cause the burners to run
continuously.
In order to test this switch it will be necessary to utilize
the temperature control hi-limit feature. Refer to PM
Card FR015 for instructions on how to perform this
test.
If the switch does not trip between the prescribed limits
it is defective and should be replaced. Once tripped, the
switch cannot be reset until the oil has cooled to
approximately 400°F + 20°F. If the switch does not
reset after oil has cooled it is defective.
Drain Valve & Return Valve Switches:
These switches are a magnetically operated proximity
switches. When the Drain Valve handle is moved to the
open position, the Actuator will move away from the
switch causing the switch to open. When the Drain Valve
is closed the switch will close.
Opening the RED return valve handle will close the
proximity switch causing the "pump on" relay to be
energized. The pump will begin to pump. Closing
the return valve handle will open the proximity switch
causing the relay to de-energize and the pump will stop
pumping. These switches can also be checked with an
Ohm meter. When the switch is closed, you should have
continuity. The normal gap between theActuator and the
Sensor switch on the valve handle is 1/8" - 1/4" (3 -
6mm).
Transformer:
The transformer is a multiple AC input voltage 24 VAC
output voltage and can be checked by reading the input
and output voltages. A quick check for 24 VAC can be
done at the relay board behind the front panel. TheAC
indicator will be illuminated if the F1 fuse is good and the
board is receiving 24 VAC.
Ignition Module:
With a 24 VAC input at pin #6, the ignition module will
have a 24 VAC output from terminal 3(PV) and the ignitor
will spark until the module senses pilot flame or for ap-
proximately 90 seconds at which time the module will lock
out, whichever occurs first. When the module has proven
the pilot flame, it will have a 24 VAC output at terminal
1(MV) and put 24 VAC to pin 2 at connection J/P32 on
the relay board. The relay board will interrupt the 24 VAC
to the gas valve until the controller calls for heat.

L22-236 Rev 0 (04/03) 6
Note: When the controller is on, the pilot should
always remain lit.
Relay Board:
Note: J connectors are marked on the relay board.
•With 24 VAC supplied to pin #2 at connector J35 and a
good F1 fuse, the relay board will have a 24 VAC output
at pin #2 on connectors J33 and J34 and the A.C. indi-
cator will be illuminated.
Note: The fryer is equipped with a computer con-
troller, at connection J33 there will be a jumper from
pin #2 to pin #10 to supply 24 VAC to pin # 2 at
connection J31 to supply the controller with 24VAC.
•When the board receives a 24 VDC side on input at pin
#7 on connectors J31 or J33, the S.O. indicator will illu-
minate, the side on relay (S.O.) will energize and there
will be a 24 VAC output at pin #4 on connector J32.
•When the board receives a 24 VDC heat demand input
at pin #6 on connectors J31 or J33, the H.D. indicator
will illuminate, the heat demand relay (H.D.) will energize
and there will be continuity between pin #1 and pin #2 at
connector J32.
Computer Control:
Note:All controller test points are at connector P/J1 (clos-
est connector to the controller).
•With 24 VAC supplied to pin #1(24VAC supply) and
pin # 5(24VAC input from DVI), the display should read
"OFF".
•With the controller turned on, there will be a 24 VDC
output at pin #9 (side on).
•When the controller calls for heat, there will be a 24
VDC output at pin #8 (heat demand) and a 24 VAC in-
put at pin #6 (heat feed back). If the controller does not
receive the 24 VAC input at pin #6 in approximately 90
seconds, the controller will display "HEAT FAIL" or "IG-
NITION FAILURE". This would indicate a break in the
heat demand or heat feed back circuit.
1. Check the hi-limit switch (is it open or tripped).
2. Check the ignition module (sensing pilot flame,
locked out, 24 VAC at MV terminal).
3. Check the heat demand relay (H.D.) on the relay
board (is heat demand relay energized, continuity
through COM and NO contacts).
•If display reads "PROBE OP" "OPEN", ohm test the
temperature probe. Check the wires and connectors be-
tween the probe and controller for continuity.
•If display reads "SYSTEM" "FAILURE", test the tem-
perature probe and the wires and connectors between the
probe and controller for a short.
•If display reads "DRAINING" "TURN OFF", verify that
the drain valve is closed, check the proximity switch on
the drain valve, turn the fryer off, then turn the fryer on.

CONVERSION INSTRUCTIONS FOR SG
MODEL FRYERS
1) Following the Fryer Start-up and Shut Down
instructionsfollowing inthismanual, shutthe appliance
off and allow the appliance to cool to room temperature.
Insure that gas supply shut-off valve (located on the gas
supply pipe before the fryer operating gas valve) is in the
“OFF”position.Remove main burners.
2) Remove all burner orifices and replace them with the
appropriate orifices for the new gas type (refer to Table
1 for proper orifice size, that will match gas type conver-
sion). Make sure that an approved gas sealant is
appliedtothe orifice threads before installingtheorifices
tothemainburnermanifold(removeburners if neces-
sary to replace orifices).
3). Burners must also be replaced if changing from LP
to NAT or NAT to LP according to the chart below.
Any gas type marked as NAT uses burner part
#B8037303 vertical slotted face burner, any gas type
marked as LP uses part #B80320001 screen mesh face
burner.
NOTE: If unit is being converted from LP to
Natural gas or Natural to LP gas, the pilot orifice
and regulator (on gas valve) must also be re-
placed with appropriate orifice and gas type regula-
tor.
4) If burners were removed, reinstall them and turn gas
supply shut-off valve to the “ON” position. Refer to
lightinginstructions andrelightthe appliance. With
burners on, check for any gas leakage around the
orifices.
5) Withmainburnersoperating,checkburnermanifold
pressure and insure that proper gas pressure is supplied
to the burner system (refer to Table 2 for pressure
settings). Adjustifnecessary.
6) Finally, apply the gas type conversion label, pro-
vided with the conversion kit, just below the fryer data
plate on the fryer door inside panel.
