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

Heed the following warnings and all other
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.

• Hot shortening can cause serious burns.

Make sure that the system and the
shortening are cool before attempting
any cleaning, adjustment, disassembly,
or repair.

• To avoid electrocution or other injury,

unplug the machine before attempting
any cleaning, adjustment, disassembly,
or repair.

• To avoid damaging the machine, never

use force to assemble, disassemble,
operate, clean, or maintain it.

• Be careful never to get shortening,

water, or other materials on the floor. If
anything does 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

Selecting a Workstation

The room in which the fryer is to be used should
provide enough air for combustion. A
ventilation hood with grease filters must be used
with the fryer. The hood must be installed and
operated in conformance with all applicable fire
codes and emissions standards.

Maintain these clearances between the sides and
back of the fryer to combustible materials:

• Sides—2 inches; and

• Back—2 inches.

The workstation should allow at least 2”/5 cm
clearance between the machine and all
construction, whether combustible or
noncombustible. In addition, it should allow
access to the rear of the fryer for cleaning and
servicing.

Unpacking the Fryer

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.

c. Using the fork lift or pallet jack, lower

the fryer to the floor. Be sure that all the
legs rest on the floor when the fryer is
level.

5. Bolt the fryer to the floor. The foot of each
leg has two holes in it for this purpose.

WARNING

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.

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

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.

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.

installation and operation instructions.

2. Make sure the drain valve is closed.

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

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

WARNING

Air spaces can cause the shortening to

overheat and catch on fire.

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.

ON again.

button on the digital controller,

WARNING

Use one of the following methods. For
safety reasons, we recommend the first
method, and discourage you from using any
other method.

• Use a Belshaw Shortening Melter (FM)

to melt shortening and transfer it to the
kettle. See the FM manual.

• 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.

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.

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.
