Preface

The 718LCG, 724CG, and 734CG Gas Fryers are
designed to fry cake and yeast-raised donut
products. Each must be bolted to a flat, dry
floor. The operator should stand opposite the
flue stack.

The operator must work safely at all times and
read this manual and follow its instructions and
warnings. A thorough understanding of how to
install, maintain, and safely operate the fryer will
prevent production delays and injuries.

warnings that appear in this manual:

• Make sure the machine is bolted securely to

the floor. Doing so will prevent the machine
from moving, tipping, or falling, which could
cause serious injury.

• Never let water and hot shortening come in

contact with each other. Moisture causes hot
shortening to spatter, which may cause
serious burns.

• Do not overfill the kettle with shortening. If

shortening overflows the kettle, it could
cause serious burns or could cause someone
to slip on the floor and be seriously injured.

get spilled on the floor, mop it up
immediately. Materials on the floor can
cause people to slip or fall, resulting in
serious injury or loss of life.

• To prevent unintentional startup and possible

fire, unplug the machine if there is a local
power outage. When the power is restored, it
is safe to plug the machine in again.

• To avoid electrocution, make sure that all

electrical cords are not frayed or cracked and
that they do not pass through any water or
shortening.

• Make sure that all electrical cords are routed

so that no one will trip over them.

• Make sure you are aware of the following:

This product contains chemicals known to
the State of California to cause birth defects
or other reproductive harm. Operation,
installation and servicing of this product

1 Operation

Taking Safety Precautions

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.

WARNING

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

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.

3. Put enough shortening in the kettle to
completely cover the burner tubes,
thermocouple, and high-temperature limit
control probe.

Put shortening in the kettle using one of

these methods:

* 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.

WARNING

Hot shortening causes severe burns.

* Melt shortening in a pan on the stove and

pour it into the kettle.

* 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. 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.

2. Make sure the drain valve is closed.

Belshaw Bros., Inc. • www.belshaw.com • Phone [phone] • Fax [phone]

718L/724/734CG Gas Fryers OM MN-1142EN 1

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.

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.

7. 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.

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.

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.

* Melt shortening in a pan on the stove and

pour it into the kettle.

* Very carefully put solid shortening into

the kettle.

WARNING

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.

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.

3 Donut-Making Helps

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 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.

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.

• Maintain the proper shortening level. We

recommend a distance of 1 1/4” between the
cutter and the shortening.

If the shortening is too deep, the donuts may

not turn over when they reach the turner,
causing them to cook unevenly.

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.

• 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.

Belshaw Bros., Inc. • www.belshaw.com • Phone [phone] • Fax [phone]

718L/724/734CG Gas Fryers OM MN-1142EN 7

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

Installing the Fryer

To avoid serious burns, other injury, or

death, make sure the fryer is securely

fastened to the floor so it will not tip or fall

over.

6. If you want to perform pressure testing on
the building’s gas supply system at pressures
greater than 0.5 psig/3.45 kPa, do so now,
before you connect the fryer to the gas
supply.

CAUTION

To avoid damaging the fryer, do not

perform pressure testing on the building’s

gas supply system at pressures greater than

0.5 psig/3.45 kPa when the fryer is
connected to the that system.

7. Connect the fryer to the gas supply, as
follows:

1. Make sure the power requirements of the
machine, found on the data plate, match
your power source.

2. Using a fork lift or pallet jack, lift the fryer
cabinet and screw each leg in as far as it will
go.

3. Set the fryer cabinet on a flat, dry floor.

4. Level the fryer. Follow these steps:

a. Check to see if the fryer is level. To do

so, place a level across the top of the
fryer cabinet.

b. If the fryer is not level, lift the fryer

using a fork lift or pallet jack, and turn
the legs to adjust them.

718L/724/734CG Gas Fryers TS MN-1143EN 3

a. Make sure the gas line to the fryer is the

right size. If it is too small, the gas
pressure at the burner manifold will be
too low, resulting in slow heat recovery,
delayed ignition, and pilot outage. (The
gas supply line on the fryer itself is
1/2”/1.3 cm I.P.S.)

b. Connect the fryer to the building’s gas

supply.

c. Seal all threaded joints between gas

pipes with pipe joint compound. You
must use a compound that resists the
action of liquefied petroleum (LP) gases.

d. Bleed the gas lines of all air.

e. Check all gas connections and fittings

for leaks using a gas leak detector, a
soap solution, or a similar substance.
When such a substance is applied to
connections and fittings, bubbles
indicate gas leaks.

WARNING

To avoid a fire or an explosion which

would cause serious burns or death, never

use an open flame to check connections for

gas leaks.

8. If you want to perform pressure testing on
the building’s gas supply system at pressures
at or below 0.5 psig/3.45 kPa, you may do so
now. Before testing, make sure the fryer’s
individual manual shutoff valve is closed.

WARNING

Do not touch hot shortening. It can cause

serious burns.

4. Remove the shortening from the fryer as
explained in “Removing the Shortening” in
Section 3.

WARNING

To avoid burns, falls, other injury, or

death, never attempt to move the fryer

when it has shortening or other liquid in it.

WARNING

9. Connect the fryer to a properly grounded
power source.

WARNING

This appliance is equipped with a three-

prong (grounding) plug for your protection

against shock hazard and should be

plugged directly into a properly grounded

three-prong receptacle. Do not cut or

remove the grounding prong from this

plug.

Moving the Fryer

If you ever want to move the fryer to a different
workstation, follow this procedure:

1. Turn off the fryer and disconnect it from the
power source.

2. Disconnect the machine from the gas supply.

Thoroughly clean and dry the floor if

shortening is spilled. Materials on the floor

can cause people to slip or fall, resulting in

serious injury or loss of life.

5. Remove the bolts that secure the fryer to the
floor.

6. Using a fork lift, transport the machine to
the new workstation.

7. Level the fryer, bolt it to the floor, connect it
to the gas line, and connect it to the power
source, as explained in “Installing the Fryer”
above.

4 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

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.

Figure A-1 summarizes this information.

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

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.

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.

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.

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.

Step 5: Check Normal
Operation

1. Set the fryer’s thermostat above
200°F/93°C.

2. Watch to see whether the pilot lights
smoothly when the gas reaches the pilot
burner.

3. Watch to see whether the main burner lights
smoothly without flashback.

4. Watch to see whether the main burner
operates smoothly without floating, lifting,
flame rollout, or heat buildup.

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.

models must be reset by setting the
thermostat below 200°F/93°C for at least
one minute before continuing. On retry
models, wait for retry or reset at the
thermostat.

* If any component does not function

properly, make sure it is correctly
installed and wired before replacing it.

* The ignition module cannot be repaired.

If it malfunctions, it must be replaced.

* Only trained, experienced service

technicians should service intermittent
pilot systems.

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

Step1:CheckIgnitionCable

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.

Troubleshooting—General

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

Belshaw Bros., Inc.  www.belshaw.com  Phone [phone]  Fax [phone]

16 MN-1143EN 718L/724/734CG Gas Fryers TS

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.

Step2:CheckIgnitionSystemGrounding

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.

Step3:CheckSparkIgnitionCircuit

You will need a short jumper wire made from
ignition cable or other heavily insulated wire.

1. Close the manual gas valve.

Arc Length What To Do

No arc, or arc less
than 1/8"/3 mm

Arc 1/8"/3 mm or
longer.

Step4:CheckPilotandMainBurner
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:

* The ignition spark continues after the

pilot is lit

Check external fuse, if
provided.
Verify power at
module input
terminal.
Replace module if
fuse and power are
okay.

Nothing. (Voltage
output is okay.)

2. Disconnect the ignition cable at the SPARK
terminal on the module.

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. 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.

4. Pull the jumper slowly away from the
terminal and note the length of the gap when
sparking stops.

5. Check the table below.

* 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)

3. 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.

Belshaw Bros., Inc.  www.belshaw.com  Phone [phone]  Fax [phone]

718L/724/734CG Gas Fryers TS MN-1143EN 17

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.

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.

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.

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.
