Operation
Taking Safety Precautions
3.
In a prominent location, post information about
what to do if there is a gas leak. Make sure that
all employees know what to do.
Put shortening in the kettle using one of
these methods:
WARNING
* If you have a Belshaw Shortening Melter
(FM) attached to the fryer, use the FM to
melt shortening and transfer it to the
kettle. See the FM manual.
To avoid the possibility of fire, explosion,
property damage, serious burns, and even
death, never store gasoline or any other
flammable liquid or vapor near the fryer.
WARNING
Hot shortening causes severe burns.
WARNING
* Melt shortening in a pan on the stove and
pour it into the kettle.
To avoid serious injury or death, if you
smell gas or suspect a gas leak, proceed as
follows: 1. Turn off the gas. 2. Evacuate
the building. 3. Do not touch any electrical
switch or telephone until you are sure no
spilled gas remains.
* Put solid shortening into the kettle,
packing it tightly around the burner
tubes.
WARNING
Frying Donuts
Air spaces can cause the shortening to
overheat and catch on fire.
WARNING
To avoid serious injury or death, before
you begin working, make sure that there is
no combustible material in the area of the
fryer.
Read each step completely before doing what it
tells you to do.
1.
2.
If you are frying yeast-raised donuts, install
the proofer or feed table. Refer to the
proofer or feed table manual for complete
installation and operation instructions.
Put enough shortening in the kettle to
completely cover the burner tubes,
thermocouple, and high-temperature limit
control probe.
CAUTION
To avoid severe damage to the kettle, never
turn on the heat unless the heat tubes are
completely covered by liquid.
4.
Move the on/off switch to the OFF position.
5.
Rotate the gas control knob counterclockwise to the ON position.
6.
Move the on/off switch to the ON position.
Make sure the drain valve is closed.

7.
The yellow pilot light near the on/off switch
and the red pilot light on the fryer cabinet
will both light up.
* Use a Belshaw Shortening Melter (FM)
to melt shortening and transfer it to the
kettle. See the FM manual.
Push the
button on the digital controller,
“SP1” will light up. This is the set point.
Push the up and down arrows to adjust the
convection heat set point. See Figure 4-4.
Push “R” button to return to operational
mode.
* Melt shortening in a pan on the stove and
pour it into the kettle.
* Very carefully put solid shortening into
the kettle.
WARNING
If the pilot fails to ignite within a certain
length of time, the gas system will go into
safety lock-out. If this happens, move the
on/off switch to OFF, wait at least one
minute, and then move the on/off switch to
ON again.
To avoid serious burns, be very careful not
to splatter hot shortening when you add
shortening to the kettle.
Because shortening expands as it increases
in temperature, put shortening in the kettle
gradually. Let the shortening in the kettle
heat up before you add more.
WARNING
Failure to wait at least one minute for the
gas to dissipate could result in a fire or an
explosion when the pilot is lighted again.
If the shortening temperature exceeds
435°F/224°C, the high-temperature limit
control will break the circuit, and the
electrical and gas systems will shut off.
If this happens, follow these steps to reset
the system:
a. Move the on/off switch to the OFF
position.
b. Wait for the shortening to cool to
385°F/196°C or below. You will not be
able to ignite the pilot until the
shortening reaches this temperature.
c. Move the on/off switch to the ON
position.
8.
Continue adding shortening to the kettle
until it reaches the proper depth for frying.
Use one of the following methods. For
safety reasons, we recommend the first
method, and discourage you from using any
other method.
9.
Wait for the shortening to reach the desired
temperature.
WARNING
To avoid serious burns, when the fryer is
operating, do not touch the flue, exhaust
manifold, stacks, gas burners, or any part
of the fryer that is in contact with hot
shortening. Keep clear from the area
above the flue outlet.
10. If you are frying cake or French donuts,
move the cutter into place over the fryer.
Refer to the cutter manual for complete
installation and operation instructions.
If you are frying yeast-raised donuts using a
feed table, load proofing cloths on the feed
table. Refer to the feed table manual for
complete installation and operation
instructions.
CAUTION
To avoid damaging the machine, do not
operate the conveyor until all the
shortening has melted.

Donut-Making Helps
If the shortening is too cold, the donuts will
spread too rapidly, will form large rings, will
tend to crack open, will be too light in
appearance, and will absorb too much
shortening.
Tips on Making Quality
Cake Donuts
•
Use the correct batter temperature.
In general, the correct batter temperature is
75°-80°F/24°-27°C. Check the mix
manufacturer’s instructions, as the
recommended temperature range may vary.
•
If the shortening is too deep, the donuts may
not turn over when they reach the turner,
causing them to cook unevenly.
If the batter is too warm, the donuts will lack
volume and may “ring out” or be misshapen.
If the batter is too cold, the donuts will stay
under the shortening too long, fry too
slowly, and crack open or ball up. They
may also absorb excess shortening and lose
volume.
•
Use the correct floor time.
A floor time of 10 minutes between mixing
and cutting allows the baking powder to
react with the water. This helps the donuts
attain the proper volume the proper level of
shortening penetration.
If the floor time exceeds 30 minutes, the mix
will gas off, the donuts will lose volume and
shape and will absorb too much shortening.
•
Use the correct frying temperature.
The correct shortening temperature for
frying is 370°-380°F/188°-193°C.
If the shortening is too hot, the donuts will
fry too quickly on the outside and will lose
volume. The donuts may also become dense
inside.
Maintain the proper shortening level. We
recommend a distance of 1 1/4” between the
cutter and the shortening.
If the shortening is too shallow (too far
below the cutter), the donuts may not drop
flat, may turn over while submerging and
surfacing, and may become irregular,
cracked, or rough-crusted.
•
Ensure that the donuts absorb the right
amount of shortening.
Donuts should absorb 1-1/2 to 3 oz/42 to 85
g of shortening per dozen, depending on
their weight. You can achieve proper
absorption by following tips 1-3.
•
If the donuts do not absorb enough
shortening, they will not keep well.
If they absorb too much shortening, they will
lose volume and may become misshapen. If
this happens, follow tips 1-3, mix the batter
a little longer than usual, turn the donuts as
soon as they become golden brown, and turn
the donuts only once.

Calculating Correct Water
Temperature
The following is an example of how to calculate
the correct water temperature to use. You must
use your own room temperature, dry mix
temperature, desired batter temperature, and, if
you are making yeast-raised donuts, estimated
temperature increase during mixing.

Temperature Conversion
To convert temperatures from Fahrenheit to
Celsius, subtract 32 from °F and divide the result
by 1.8. For example, 212°F-32/1.8 = 100°C.
To convert temperatures from Celsius to
Fahrenheit, multiply °C by 1.8 and add 32 to the
result. For example, (100°C x 1.8) + 32 = 212°F.

Pilot Module
This section contains supplemental information
about the Honeywell S8600 Intermittent Pilot
Module. The Belshaw 718LCG, 724CG, and
734CG gas fryers all use this module. Fryers
using natural gas use the S8600F-1000. Fryers
using propane use the S8600H-1014.
Belshaw provides this appendix as a courtesy to
our customers. We deny any liability for the use
of the information contained herein. All of the
procedures explained below should be performed
by qualified technicians.

WARNING
To avoid fire or explosion, resulting in
property damage, injury, or loss of life, if
you smell gas or suspect a gas leak, turn off
the gas at the manual service valve and
evacuate the building. Do not try to light
any appliance or touch any electrical
switch or telephone in the building until
you are sure no spilled gas remains.
Step 1: Perform Visual
Inspection
1.
Make sure the fryer’s on/off switch is in the
OFF position. Make sure all wiring
connections are clean and tight. If they are
not, correct them.
2.
Move the on/off switch to ON.
3.
Open the manual shutoff valves in the gas
line to the fryer.
4.
If the piping has been disturbed, perform a
gas leak test ahead of the gas control, as
follows:
a. Paint the pipe joints with a rich solution
of soap and water. Bubbles in the
solution indicate gas leaks.
b. If there are leaks, tighten the joints.
c. Test again for leaks.
d. Repeat this procedure until no leaks
exist.
Step 2: Review the Normal
Operating Sequence
Figure A-1 summarizes this information.
WARNING
To avoid fire or explosion, resulting in
property damage, injury, or loss of life,
perform gas leak tests as explained in Steps
1 and 5 below at the time of initial
installation and at any time work is done
involving the gas piping.
Trial for Ignition
When the fryer’s thermostat calls for heat, the
module energizes the first main valve operator.
The first main valve opens, allowing gas to flow
to the pilot burner. At the same time, the
electronic spark generator in the module
produces a spark pulse output of over 10,000
volts. The voltage generates a spark at the
igniter-sensor that lights the pilot.
If the pilot does not light, or if the pilot flame
current is not at least 1.0 A and steady, the
Belshaw Bros., Inc.  www.belshaw.com  Phone 206-322-5474  Fax 206-322-5425

MN-1143EN
13
module will not energize the second main valve,
and the main burner will not light. The S8600F,
which is used on natural gas fryers, will continue
to spark as long as the fryer’s thermostat calls for
heat or until the pilot lights.
The S8600H, which is used on propane fryers,
provides 100 percent shutoff and safety lockout.
Its ignition sparks only for a pre-set length of
time (15 or 90 seconds, as stamped on the
module). If the pilot does not light within the
timed trial for ignition period, the module goes
into safety lockout, de-energizing the first main
valve operator, closing the first main pilot valve
in the gas control, and stopping the flow of gas to
the pilot. You must then set the fryer’s
thermostat below 200°F/93°C, move the on/off
switch to OFF, and wait at least one minute
before trying again to light the pilot.
Watch to see whether there is a spark at the
pilot burner immediately.
3.
Time the spark from the time it starts to the
time it shuts off.
4.
Compare this time with the shutoff time that
is stamped on the module. They should be
the same.
5.
Open the manual gas cock and make sure
that no gas is flowing to the pilot or main
burner.
6.
Set the fryer’s thermostat below 200°F/93°C
and wait at least one minute before
continuing.
Main Burner Operation
When the pilot flame is established, a flame
rectification circuit is completed between the
sensor and the burner ground. The flame sensing
circuit in the module detects the flame current,
shuts off the spark generator, and energizes the
second main valve operator. The second main
valve opens and gas flows to the main burner,
where it is ignited by the pilot burner. On the
S8600H, the safety lockout timer is held in the
normal operating mode.
When the thermostat no longer calls for heat,
both valve operators are de-energized, and both
valves in the gas control close.
Step 3: Reset the Module
1.
Turn the thermostat to its lowest setting.
2.
Wait at least one minute.
Step 4: Check Safety Shutoff
Operation
This step applies only to the S8600H, which is
used on propane fryers.
1.
Turn the gas supply off.
2.
Set the fryer’s thermostat above
200°F/93°C.

operates smoothly without floating, lifting,
flame rollout, or heat buildup.
* Only trained, experienced service
technicians should service intermittent
pilot systems.
5.
If the gas line has been disturbed, perform a
gas leak test, as follows:
a. Paint the gas control gasket edges and all
pipe connections downstream of the gas
control, including pilot tubing
connections, with a rich solution of soap
and water. Bubbles in the solution
indicate gas leaks.
b. If there are leaks, tighten the joints or
screws, or replace the component.
c. Test again for leaks.
d. Repeat this procedure until no leaks
exist.
6.
Set the thermostat below 200°F/93°C.
Watch to see whether the main burner flame
and the pilot flame go out.
Troubleshooting—General
As the first step in troubleshooting, perform the
checkout procedure. Then check the block
diagram. If you think there is an ignition
problem, see “Troubleshooting the Ignition
System” below to isolate and correct the
problem.
Following troubleshooting, perform the checkout
procedure again to be sure system is operating
normally.
Troubleshooting the
Ignition System
Step1:CheckIgnitionCable
1. Make sure the ignition cable does not run in
contact with any metal surfaces.
2.
Make sure the ignition cable is no more than
36”/0.9 m long.
3.
Make sure the connections to the ignition
module and to the igniter-sensor are clean
and tight.
4.
Make sure the ignition cable provides good
electrical continuity.
The following service procedures are provided as
a general guide.
For electrical troubleshooting, refer to the
diagrams included with this manual or to the
diagram on the inside of the fryer door. Heed all
warnings and cautions.
* On lockout and retry models, meter
readings between gas control and
ignition module must be taken within the
trial for ignition period. Once the
ignition module shuts off, lockout
Step2:CheckIgnitionSystemGrounding
Nuisance shutdowns are often caused by a poor
or erratic ground.
A common ground, usually supplied by the pilot
burner bracket, is required for the module and the
pilot burner/igniter-sensor.

1.
Check for good metal-to-metal contact
between the pilot burner bracket and the
main burner.
2.
Check the ground lead from the GND
(BURNER) terminal on the module to the
pilot burner. Make sure the connections are
clean and tight. If the wire is damaged or
deteriorated, replace it with #14-18 gauge,
moisture-resistant, thermoplastic-insulated
wire with a 221°F/105°C minimum rating.
3.
Check the ceramic flame rod insulator for
cracks or evidence of exposure to extreme
heat, which can permit leakage to the
ground. Replace the pilot burner/ignitersensor and provide a shield if necessary.
If the flame rod or the bracket are bent out of
position, restore them to the correct position.
Step3:CheckSparkIgnitionCircuit
You will need a short jumper wire made from
ignition cable or other heavily insulated wire.
Arc Length
What To Do
No arc, or arc less
than 1/8"/3 mm
Check external fuse, if
provided.
Verify power at
module input
terminal.
Replace module if
fuse and power are
okay.
Arc 1/8"/3 mm or
longer.
Nothing. (Voltage
output is okay.)
Step4:CheckPilotandMainBurner
Lightoff
1. Set the thermostat above 200°F/93°C to call
for heat.
2.
Watch the pilot burner during the ignition
sequence. Look for the following:
1.
Close the manual gas valve.
* The ignition spark continues after the
pilot is lit
2.
Disconnect the ignition cable at the SPARK
terminal on the module.
* The pilot lights and the spark stops, but
the main burner does not light
* The pilot lights, the spark stops and the
main burner lights, but the system shuts
down (S8600H only)
WARNING
To avoid electric shock, when performing
the following steps, do not touch the
stripped end of the jumper or the SPARK
terminal. The ignition circuit generates
over 10,000 volts.
3.
4.
5.
Energize the module and immediately touch
one end of the jumper firmly to the GND
terminal on the module. Move the free end
of the jumper slowly toward the SPARK
terminal until a spark is established.
Pull the jumper slowly away from the
terminal and note the length of the gap when
sparking stops.
Check the table below.

If any of the these things happens, make sure
the flame current is adequate. Follow these
steps:
a. Turn off the fryer and disconnect it from
the power source.
b. Clean the flame rod with emery cloth.
c. Make sure the electrical connections are
clean and tight. Replace damaged wire
with moisture-resistant #18 wire rated
for continuous duty up to 221°F/105°C.
d. Check to see if ceramic insulator is
cracked. A cracked insulator can cause a
short to ground. Replace the ignitersensor if necessary.

e. At the gas control, disconnect the main
valve wire from the TH or MV terminal.
f. Connect the fryer to the power source
and move the on/off switch to the ON
position.
Appearance
Cause
small blue flame
lack of gas due to
clogged orifice filter
lack of gas due to
clogged pilot filter
g. Turn on the power and set thermostat
above 200°F/93°C to call for heat. The
pilot should light, but the main burner
will remain off because the main valve
actuator is disconnected.
h. Check the pilot flame. Make sure it is
blue, steady, and envelops 3/8-1/2”/
10-13 mm of the flame rod. See the
table below for possible flame problems
and their causes.

low gas supply
pressure
pilot adjustment is at
minimum
lazy yellow flame
lack of air due to large
orifice
pilot adjustment is at
minimum
i. If necessary, adjust the pilot flame by
turning the pilot adjustment screw on the
gas control clockwise to decrease or
counterclockwise to increase the pilot
flame. Following adjustment, always
replace the pilot adjustment cover screw
and tighten it firmly to assure proper gas
control operation.
waving blue flame
noisy lifting blowing
flame
high gas pressure
j. Set the thermostat below 200°F/93°C to
end the call for heat.
hard sharp flame
high gas pressure
Recheck the ignition sequence as follows:
excessive draft at pilot
location
products of
combustion are
recirculating
orifice too small
a. Reconnect the main valve wire.
b. Set the thermostat above 200°F/93°C to
call for heat.
c. Watch the ignition sequence at the
burner.
If the spark still does not stop after the
pilot lights, replace the ignition module.
If the main burner does not light, check
for 24V AC across MV-MV/PV
terminals. If there is no voltage, replace
the module. Also, check the electrical
connections between the module and the
gas control. If they are okay, replace the
gas control or the gas control operator.
