G18FB & G24FB SERIES GAS FRYERS

CHAPTER 1: GENERAL INFORMATION

Your fryer is equipped with automatic safety
features:

1. High temperature detection shuts off gas to
the burner assembly should the controlling
thermostat fail.

2. An optional safety switch built into the
drain valve prevents burner ignition with
the drain valve even partially open.

1.3 Equipment Description

The G18FB and G24FB Series of gas fryers
are designed as liquid-batter style units. They
are capable of producing up to 50 pounds/25
liters (G18FB) or 65 pounds/36 liters (G24FB)
per hour of uniformly cooked fish, shrimp,
chicken, tempura, and similar products. The
fryers in this series employ an infrared burner
system to generate 80,000 BTU/hr (20,000
kcal, 84.4 megajoules, 23.4 kW).

into the center of the frypot, with a front­operated manual ball valve. Heating is sup­plied by a pair of burner assemblies mounted
beneath the frypot. Combustion air for the
burners is supplied by a dedicated blower.

Each frypot is equipped with a temperature
probe for precise temperature control. The
probe is located on the centerline of the frypot
for rapid response to changes in loads, and to
provide the most accurate temperature meas­urement.

The fryers in this series can be configured for
natural gas or Propane (LP) gas, as required by
the customer.

All fryers come standard with electronic igni­tion. Control options include Computer Magic
III com put er s or sol id -st at e an alo g co ntr ol ler s.
Each type is covered in detail in Chapter 3,
Operating Instructions.

Fryers may be ordered without any built-in
filtration capability (G18FB/G24FB) or ready
for attachment to an existing Filter Magic II
filtration system (FG18FB/FG24FB). The fry­ers can also be ordered with a Filter Magic II
system positioned on either side of the fryer
(FMG18FB/FMG24FB). Additionally, up to
four units can be batteried to either side of a
Filter Magic II built-in filtration system to cre­ate a high-production frying station. In
January 1998, the FPG18FB variant entered
production, adding the advantages of the
FootPrint III built-in filtration system to the
earlier Filter Magic option.

All fryers in this series are of an open-pot,
flat-bottomed design with no tubes, which
makes cleaning the frypot quick and easy.

Frypots are constructed of welded heavy­gauge stainless steel. A drain valve is tapped

All fryers in this series require an external
source of AC electrical power. Units can be
configured for voltages ranging from 120
VAC to 220 VAC.

Fryer s eq uip ped wit h Foo tP rin t III bu ilt-in fil­tration systems are shipped completely
assembled. Fryers without the FootPrint III
require installation of legs or optional casters
at point of use. All fryers are shipped with a
package of standard accessories. Each fryer is
adjusted, tested, and inspected at the factory
before crating for shipment.

CHAPTER 2: INSTALLATION INSTRUCTIONS

2.1 General Installation
Requirements

PROPER INSTALLATION IS ESSENTIAL FOR
EFFICIENT, TROUBLE-FREE OPERATION OF
YOUR FRYER. ANY UNAUTHORIZED AL­TERATIONS MADE TO THIS EQUIPMENT WILL
VOID THE FRYMASTER

WARRANTY.

Upon arrival, inspect the fryer carefully for
visible or concealed damage. (See Shipping
Damage Claim Procedure in Chapter 1.)

CLEARANCE AND VENTILATION

The fryer(s) must be installed with a 6” (150
mm) clearance at both sides and back when
installed adjacent to combustible construction;
no clearance is required when installed adja­cent to noncombustible construction. A
minimum of 24” (600 mm) clearance should
be provided at the front of the fryer(s). Air for
combustion enters the fryer(s) below the cabi­net base.

One of the most important considerations of
efficient fryer operation is ventilation. Make
sure the fryer is installed so that products of
combustion are removed efficiently, and that
the kitchen ventilation system does not pro­duce drafts that interfere with proper burner
operation.

The fryer flue opening must not be placed
close to the intake of the exhaust fan, and the
fryer must never have its flue extended in a
“chimney” fashion. An extended flue will
change the combustion characteristics of the
fryer, causing longer recovery time. It also
frequently causes delayed ignition. To pro­vide the airflow necessary for good combus­tion and burner operation, the areas surround­ing the fryer front, sides, and rear must be kept
clear and unobstructed.

Fryers must be installed in an area with an
adequate air supply and adequate ventilation.
Adequate distances must be maintained from
the flue outlet of the fryer to the lower edge of
the ventilation filter bank. Filters should be
installed at an angle of 45º. Place a drip tray
beneath the lowest edge of the filter. For U.S.
installation, NFPA standard No. 96 states, “A
minimum distance of 18 in. (450 mm) should
be maintained between the flue outlet and the
lower edge of the grease filter.” Frymaster

recommends that the minimum distance be 24
in. (600 mm) from the flue outlet to the bottom
edge of the filter.

Information on construction and installation of
ventilating hoods can be found in the NFPA
standard cited above. A copy of the standard
may be obtained from the National Fire Pro­tection Association, Battery March Park,
Quincy, MA 02269.

DANGER

Do not attach an apron drainboard to a

single fryer. The fryer may become

unstable, tip over, and cause injury.

The appliance area must be kept free

and clear of combustible material at all

times.

NATIONAL CODE REQUIREMENTS

The type of gas for which the fryer is equipped
is stamped on the data plate attached to the
inside of the fryer door. Connect a fryer

stamped “NAT” only to natural gas, and
those stamped “PRO” only to propane gas.

Installation shall be made with a gas connector
that complies with national and local codes.
Quick-disconnect devices, if used, shall like­wise comply with national and local codes.

CHAPTER 2: INSTALLATION INSTRUCTIONS

2.3 Pre-Connection Preparations

DANGER

Do not connect fryer to gas supply

before completing each step

in this section.

After the fryer has been positioned under the
fry station exhaust hood, ensure the following
has been accomplished:

1. Adequate means must be provided to limit

the movement of fryers without depending
upon the gas line connections. If a flexible
gas hose is used, a restraining cable must
be connected at all times when the fryer is
in use. The restraining cable and installa­tion instructions are packed with the flexi­ble hose in the accessories box that was
shipped with your unit.

2. Single unit fryers must be stabilized by

installing restraining chains on fryers
equipped with casters or anchor straps on
fryers equipped with legs. Follow the in­structions shipped with the casters/legs to
properly install the chains or straps.

3. Level fryers equipped with legs by screw-

ing out the legs approximately 1 inch then
adjusting them so that the fryer is level and
at the proper height in the exhaust hood.

Frymaster

Frymaster

FrymasterFrymaster

recommends that the minimum
distance from the flue outlet to the bottom
edge of the filter be 24 in. (600 mm).

4. Test the fryer electrical system:

a. Plug the fryer electrical cord(s) into a

grounded electrical receptacle.

b. Place the power switch in the ON

position.

• For fryers equipped with analog

controls, verify that the power and
heat lights are lit.

• For fryers having computers, verify
that the display indicates CYCL.

c. Place the fryer power switch in the

OFF position. Verify that the power
and heat lights are out, or that the dis­play is blank.

5. Refer to the data plate on the inside of the
fryer door to determine if the fryer burner
is configured for the proper type of gas be­fore connecting the fryer to the gas supply
line.

6. Verify the minimum and maximum gas
supply pressures for the type of gas used in
accordance with the table below.

Before connecting new pipe to your unit, the
pipe must be thoroughly blown out to remove
any foreign particles. If these foreign particles
get into the burner and controls, they will
cause improper and sometimes dangerous op­eration.

1. Connect the fryer gas line, located at the left rear of the unit, to the building

gas line. Use a very small amount of pipe thread compound on male threads only.
Use a compound that is not affected by the chemical action of LP gases (Loctite
PST56765 Sealant is one such compound). DO NOT apply compound to the first
two threads. This will ensure that the burner orifices and control valve do not
become clogged.

2. Open the gas supply to the fryer and check

all piping, fittings, and gas connections for
leaks. A soap solution should be used for
this purpose.

DANGER

Never use matches, candles, or any

other ignition source to check for

leaks.

If gas odors are detected, shut off the

gas supply to the fryer

at the main shut-off valve and contact

the local gas company or an

authorized service agency for service.

3. Close the fryer drain valve and fill the fry­pot with water and boil-out solution to the
bottom OIL-LEVEL line at the rear of the
frypot. Light the fryer and perform the
boil-out procedures that are described in
the “Lighting Instructions” and “Boiling
Out the Frypot” topics found in Chapter 3
of this manual.

WARNING

“Dry-firing” your unit will cause

damage to the frypot. Always ensure

that melted shortening, cooking oil, or

water and boil-out solution is in the
frypot before firing your unit for any

extended period.

•

4. It is suggested that the burner manifold

pressure be checked at this time by the lo­cal gas company or an authorized service
agent. Refer to “Check Burner Manifold

.

1. Turn the fryer power switch to the OFF
position. Screw the drainpipe (provided
with your fryer) into the drain valve.
Make sure the drainpipe is firmly screwed
into the drain valve and that the opening is
pointing down.

DANGER

DO NOT insert anything into the drain

from the front to unclog the valve. Hot

oil/shortening will rush out, creating an

extreme hazard.

WARNING

DO NOT hammer on the drain valve

with the Fryer’s Friend. This will

damage the drain valve ball and

prevent the valve from sealing

securely, resulting in a leaky valve.

Draining the FPG18FB Fryer

The FPG18FB fryer is equipped with a quick­disconnect fitting for attaching a wand assem­bly, allowing the filter pump to be used to
transfer used oil to an oil disposal container.

1. Verify that the filter pan is positioned all

the way to the rear of the unit. The green

FILTER READY light will be illuminated

when the pan is properly positioned.

2. Position a metal container with a sealable
cover under the drainpipe. The metal
container must be able to withstand the
heat of the cooking oil/shortening and hold
hot liquids. If you intend to reuse the oil
or shortening, Frymaster recommends that
a Frymaster filter cone holder and filter
cone be used when a filter machine is not
available. If you are using a Frymaster
filter cone holder, be sure that the cone
holder rests securely on the container.

3. Open the drain valve slowly to avoid
splattering. If the drain valve becomes
clogged with food particles, use the
Fryer’s Friend (poker-like tool) to clear the
blockage.

2. Press the computer power switch to turn

the computer off. Slowly open the drain
valve, allowing the oil to drain into the
filter pan.

4-1

G18FB & G24FB SERIES GAS FRYERS

If the drain valve becomes clogged with
food particles, use a stiff wire or thin rod
to clear the blockage.

DANGER

DO NOT insert anything into the drain

from the front to unclog the valve. Hot

oil/shortening will rush out, creating an

extreme hazard.

WARNING

DO NOT hammer on the drain valve.

This will damage the drain valve ball

securely, resulting in a leaky valve.

3. P ull back on the orange collar of the wand

assembly and position the hose-end fitting
onto the quick-disconnect fitting of the
fryer. Release the collar and pull firmly on
the hose near the collar to ensure that the
hose is securely attached.

5. Holding the wand handle firmly, with the

end inserted well into the disposal con­tainer, press the Dispose Wand switch to
the ON position.

The filter pump will energize, pumping oil
from the filter pan through the wand and
into the disposal unit.

6. When the filter pan has been emptied,

press the Dispose Wand switch to the OFF
position and move the Filter/Wand valve
handle to the OFF (center) position.

4. P lace the end of the wand i nto the di sposal

container and move the Filter/Wand valve
handle as far as it will go to the right.

7. Make sure the wand assembly is com-

pletely drained by lowering the discharge
end to a level below the quick-disconnect
fitting, allowing any remaining oil in the
hose to drain into a metal container.

When sure that no oil remains in the hose,
remove the hose by pulling back on the or­ange collar to release the hose from the
quick-disconnect fitting.

After Draining (All Models)

1. After draining, clean all food particles and

residual oil from the frypot. BE CARE­FUL, this material may still cause severe
burns if it comes in contact with bare skin.

2. Close the drain valve securely and fill the

frypot with fresh cooking oil or solid
shortening to the bottom OIL-LEVEL line.

4-2

G18FB & G24FB SERIES GAS FRYERS

CHAPTER 4: FILTRATION INSTRUCTIONS

DANGER

When using solid shortening, pack the

shortening down into the bottom of the

frypot. DO NOT operate the fryer with

a solid block of shortening sitting in

the middle of the frypot. This will

cause damage to the frypot and may

cause a flash fire.

4.2 Built-In Filtration System

Operation

Your fryer’s built-in filtration system allows
the cooking oil or shortening in one frypot to
be safely and efficiently filtered while the
other frypots in a battery remain in operation.

The majority of reported problems with the
built-in filtration system are found to be the
result of improper operation. Careful attention
to the step-by-step instructions that follow will
ensure that your system operates as intended.

PREPARING THE FILTER UNIT FOR USE

1. Slide the filter unit from the cabinet and
remove the filter pan lid, if so equipped.

2. Remove the crumb tray and paper hold­down ring.

3. Ensure that the metal filter screen is in the

bottom of the pan.

4. Lay a sheet of filter paper over the top of

the filter pan, overlapping on all sides.
Position the hold-down ring over the filter
paper and lower the ring into the pan, al­lowing the paper to fold up around the ring
as it is pushed to the bottom of the pan.

OPERATION OF THE FILTER UNIT

CAUTION

Never operate the filter unit unless the

cooking oil in the fryers has been

brought up to cooking temperature.

1. To filter the cooking oil, turn the fryer

power OFF, then open the drain valve on
the fryer you have selected to be filtered.
Use the Fryer's Friend steel rod to clear
the drain from inside the frypot if neces­sary. Drain valve locations will vary de­pending upon the particular configuration
of your equipment (i.e., FMG18FB or
FMG24FB, FPH150-G18FB combination,
or FPG18FB).

DANGER

Never drain more than one fryer at a

time—the filter pan may overflow.

When unclogging a valve, DO NOT
insert anything into the drain from the
front of the fryer. Hot oil will rush out,

creating an extreme hazard.

WARNING

DO NOT hammer on the drain valve

with the Fryer’s Friend. This will

damage the drain valve ball and

prevent the valve from sealing

securely, resulting in a leaky valve.

2. When the frypot is empty, use a fryer

CHAPTER 5: PREVENTIVE MAINTENANCE

5.1 Fryer Preventive Maintenance
Checks and Services

DAILY CHECKS AND SERVICES

Inspect Fryer and Accessories for Damage

Look for loose or frayed wires and cords,
leaks, foreign material in frypot or inside
cabinet, and any other indications that the
fryer and accessories are not ready and safe for
operation.

Clean Fryer Cabinet Inside and Out

Clean inside the fryer cabinet with dry, clean
cloth. Wipe all accessible metal surfaces and
components to remove accumulations of oil or
shortening and dust.

Clean the outside of the fryer cabinet with a
clean, damp cloth soaked with dishwashing
detergent, removing oil/shortening, dust, and
lint from the fryer cabinet.

WEEKLY CHECKS AND SERVICES

Drain and Clean Frypot

During normal usage of your fryer, a deposit
of carbonized cooking oil or shortening will
gradually form on the inside of the frypot.
This deposit must be periodically removed to
maintain your fryer’s efficiency.

If your fryer is not equipped with a built-in
filtration system, the cooking oil or shortening
must be drained into another suitable con­tainer. (For safe, convenient draining and
disposal of used cooking oil or shortening,
Frymaster recommends using our Shortening
Disposal Unit (SDU). The SDU is available
through your local distributor.)

1. Place the fryer power switch in the OFF
position. Screw the drainpipe (provided
with your fryer) into the drain valve.
Make sure the drainpipe is firmly screwed
into the drain valve and that the opening is
pointing down.

DANGER

Never attempt to clean fryer during the

cooking process or when the frypot is

filled with hot oil/shortening. If water

comes in contact with oil/shortening

heated to cooking temperature, it can

cause the oil/shortening to splatter and

severely burn nearby personnel.

Filter Cooking Oil/Shortening

Filter cooking oil/shortening in accordance
with the instructions in Chapter 4 at least once
daily, just before the fryer is shut down for the
day. Additional filtering may be required
during the day depending upon amount and
type of product being fried.

2. Position a metal container with a sealable
cover under the drainpipe. The metal
container must be able to withstand the
heat of the cooking oil/shortening and hold
hot liquids. If you intend to reuse the oil
or shortening, Frymaster recommends that
our filter cone holder and filter cone be
used when a filter machine is not avail­able. If you are using a Frymaster filter
cone holder, be sure that the cone holder
rests securely on the metal container.

3. Open the drain valve slowly to avoid
splattering. If the drain valve becomes
clogged with food particles, use the
Fryer’s Friend (poker-like tool) to clear the
blockage.

5-1

G18FB & G24FB SERIES GAS FRYERS

CHAPTER 5: PREVENTIVE MAINTENANCE

DANGER

DO NOT insert the tool into the drain

from the front to unclog the valve. Hot

oil/shortening will rush out, creating an

extreme hazard.

WARNING

DO NOT hammer on the drain valve.

This will damage the drain valve ball

and prevent the valve from sealing

securely, resulting in a leaky valve.

4. After draining the oil/shortening, clean all
food particles and residual oil/shortening
from the frypot. BE CAREFUL, this ma­terial may still cause severe burns if it
comes in contact with bare skin.

5. Close the drain valve securely and fill the
frypot with a solution of detergent and
water to the bottom OIL-LEVEL line.
(Frymaster recommends the use of
Frymaster Boilout Solution, available
through your local distributor, for best
results.)

9. Drain the solution into a suitable container

(NOT the built-in filtration system filter
pan or the Shortening Disposal Unit)

and thoroughly wipe the frypot with a
clean towel.

10. Close the drain valve and fill the frypot
with clean, cold water and drain. Repeat
the rinse process again, and then wipe fry­pot with a clean, dry towel.

DANGER

Ensure that the frypot is completely

free of water before filling with cooking

oil or shortening. When the oil or

shortening is heated to cooking

temperature, water in the frypot will

CHAPTER 6: OPERATOR TROUBLESHOOTING

6.1 Introduction

This chapter provides an easy reference guide
to the more common problems that may occur
during the operation of your equipment. The
troubleshooting guides in this chapter are
intended to help you correct, or at least
accurately diagnose, problems with your
equipment. Although the chapter covers the
most common problems reported, you may
very well encounter a problem not covered. In
such instances, the Frymaster Technical
Service Department will make every effort to
help you identify and resolve the problem.

When troubleshooting a problem, always use a
process of elimination starting with the
simplest solution and working through to the
most complex. Never overlook the obvious.
Anyone can forget to plug a cord into a
receptacle or put a piece of filter paper into a
filter pan. Don’t assume that you are exempt
from such occurrences.

Most importantly, always try to establish a
clear idea of why a problem has occurred.
Part of your corrective action involves taking
steps to ensure that it doesn’t happen again. If
a controller malfunctions because of a poor
connection, check all other connections while
you’re at it. If a fuse continues to blow, find
out why. Always keep in mind that failure of
a small component may often be indicative of
potential failure or incorrect functioning of a
more important component or system.

Several of the corrective actions recommended
in this chapter involve removing a suspect
controller from the system and substituting

one that is known to be good. Whenever this
in indicated, refer to Section 6.4 for specific
instructions.

Each guide begins with a description of a
common problem in a six-sided figure.
Simply follow the arrows and answer the
questions to determine the corrective action to
take.

If you are in doubt as to the proper action to
take, do not hesitate to call the Frymaster
Technical Service Department or your local
Frymaster Factory Authorized Service Center
for assistance.

DANGER

Hot cooking oil or shortening causes

severe burns. Never attempt to move a

fryer containing hot cooking

oil/shortening or to transfer hot

cooking oil/shortening from one

container to another.

DANGER

Use extreme care when performing

electrical circuit tests. Live circuits

will be exposed.

WARNING

Inspection, testing, and repair of

electrical equipment should be

performed only by qualified service

personnel. The equipment should be

unplugged when servicing, except

when electrical tests are required.
