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.
1.3Equipment 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.

2.1General 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 ShippingDamage 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.

2.3Pre-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.

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.
