Preface

The 718LFG, 724FG, and 734FG 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.

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

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.

Controls

Initial Lighting

This procedure is required only after a
complete shut down or installation.

Light the fryer as follows:

1. Turn the thermostat knob to the OFF

position. Wait five minutes.

2. Rotate the gas control knob counterclockwise

to the PILOT position. Fully depress the
knob and hold it down while lighting the
pilot burner. Continue to hold down the
knob approximately one minute. Release the
knob and check to see that the pilot burner
remains lit. Turn the knob to ON.

3. Turn the thermostat knob to the desired

temperature to light the main burners.

Complete Shut Down

This procedure is only required before
servicing.

Turn the gas control knob clockwise from the
ON position to the PILOT position. Slightly
depress the knob and turn to OFF position.

The gas cock knob on the gas control has three
settings: Off, Pilot, and On.

Off: Prevents any gas from passing through the
valve to either main or pilot burner.

Pilot: Permits gas to flow to pilot burner only
(when gas cock knob is held depressed or when
generator is heated sufficiently to hold valve
open)

On: Permits gas to flow to both main and pilot
burners when the system is functioning correctly.

Frying Donuts

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. Make sure the drain valve is completely
closed.

2. 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

(EZ) attached to the fryer, use the EZ to
melt shortening and transfer it to the
kettle. See the EZ Melt manual.

WARNING

Hot shortening causes severe burns.

• Melt shortening in a pan on the stove

and pour it into the kettle.

The yellow pilot light near the on/off switch

and the red pilot light on the fryer cabinet
will both light up.

6. Turn the thermostat control knob to the
desired temperature. This will cause the
pilot to ignite. Also, the yellow pilot light
on the fryer cabinet will light up, indicating
that the thermostat is calling for heat.

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.

• Put solid shortening into the kettle,

packing it tightly around the burner
tubes.

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.

3. Move the on/off switch to the OFF position.

4. Rotate the gas control knob
counterclockwise to the ON position.

5. Move the on/off switch to the ON position.

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.

7. 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.

• 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.

8. Wait for the shortening to reach the desired
temperature.

10. Continue supplying shortening to the kettle
as required. Keep the kettle filled up to the
“Oil Level” marks on the side.

11. When you are done frying donuts, move the
on/off switch to the OFF position.

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.

9. 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.

CAUTION

To avoid damaging the machine, do not

operate the conveyor until all the

shortening has melted.

2 Cleaning

For your safety, observe the following warnings
throughout the entire cleaning process.

WARNING

Thoroughly clean and dry the floor if

shortening, water, or other materials are

spilled. Materials spilled on the floor can

cause serious injury or loss of life.

WARNING

To avoid electrocuting yourself or

damaging the machine, never allow water,

steam, shortening, cleaning solution, or any

other liquid to enter the electrical box.

WARNING

To avoid serious burns while cleaning, do

not touch the flue, exhaust manifold,

stacks, gas burners, or any part of the fryer

that is in contact with hot liquids.

Removing the Shortening

1. Let the shortening cool to 100°F/38°C.

2. Place a Belshaw Shortening Filter or a large
metal container under the drain valve of the
fryer.

WARNING

Do not use a plastic container. If the

shortening is not cool enough, the container

will melt, possibly causing you to be

burned, and causing shortening to get on

the floor.

3. Open the drain valve by turning the drain
valve extension knob on the side of the fryer
cabinet. Allow all the shortening to drain
into the Shortening Filter or metal container.

4. If you are using a metal container, watch it
to make sure the shortening does not
overflow. If the container becomes full,
close the drain valve, put another metal
container under the drain valve, and open
the drain valve again.

WARNING

There are four basic steps to cleaning the fryer:
removing the shortening, washing, rinsing, and
drying. You must perform all four steps and
perform them in the order listed.

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

4 MN-1147EN 718L/724/734FG Gas Fryers OM

Do not allow the shortening to overflow the

containers. Shortening will get on the

floor, and if the shortening is not cool

enough, you may be burned.

WARNING

Thoroughly clean and dry the floor if

shortening is spilled. Shortening on the

floor can cause serious injury or loss of life.

5. Using a non-abrasive, non-metallic spatula,
scrape the sediment and any remaining
shortening into the drain valve.

WARNING

To avoid fire, serious injury, and

equipment damage, do not attempt to burn

carbon off of the heat tubes.

6. Close the drain valve.

7. If your fryer has a Belshaw Shortening
Melter (FM) connected to it, install the plug
into the reservoir nipple.

2. Connect the fryer to the power source.
Move the on/off switch to ON. Set the
temperature control to 200°F/93°C. Keep
the cleaning solution at this temperature for
15-20 minutes.

3. Scrub the soiled parts while the solution is
hot. Do not use any abrasive cleaners or
scrapers.

WARNING

To avoid being burned, be very careful as

you work with hot cleaning solution. Never

put your hands in the solution. Wear

gloves and long sleeves in case any solution

splashes.

4. Shut off the fryer. Allow the cleaning
solution to cool to 100°F/38°C.

5. Place a large metal container under the drain
valve.

Washing

1. Pour hot water into the kettle, up to the
normal level of the shortening. Add
trisodium phosphate or another appropriate
cleaner.

CAUTION

To avoid severe damage to the kettle, never

turn on the heat unless the heat tubes are

completely covered by liquid.

WARNING

Do not use plastic containers. If the

cleaning solution is not cool enough, the

containers will melt; possibly causing you

to be burned, and causing cleaning solution

to get on the floor.

6. Open the drain valve and allow the cleaning
solution to drain into the container.

7. Watch the container to make sure the
cleaning solution does not overflow. If the
container becomes full, close the drain
valve, put another large metal container
under the drain valve, and open the drain
valve again.
