CHAPTER 1: INSTALLATION
1-1
1.1 Gas Connections
DANGER
Before connecting new pipe to this appliance the pipe must be blown out thoroughly
to remove all foreign material. Foreign material in the burner and gas controls will
cause improper and dangerous operation.
NATIONAL CODE REQUIREMENTS
This equipment is to be installed in compliance with the Basic Plumbing Code of the Building
Officials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation
Manual of the U.S. Food and Drug Administration.
This equipment is manufactured to use the type of gas specified on the rating plate attached to the
door. Connect equipment stamped "NAT" only to natural gas and that stamped "PRO" only to LP
(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.
DANGER
The fryer MUST be connected to the gas supply specified on the rating and serial number
plate located on the back of the fryer door.
DANGER
If gas odors are detected, the gas supply MUST be shut off at the main shut-off valve. The
local gas company or FASC should be contacted immediately to rectify the problem.
A. The gas supply (service) line must be the same size or greater than the fryer inlet line. This
fryer is equipped with a 3/4" (22 mm) male inlet. The gas supply line must be sized to
accommodate all the gas-fired equipment that may be connected to that gas supply. Consult
your contractor, gas company, supplier, or other knowledgeable authorities.
Recommended Gas Supply Line Sizes
Gas Types Number of Fryers
1 2 to 3 4 or more (*)
Natural Gas 3/4" (22 mm) 1" (28 mm) 1-1/4" (35 mm)
Propane Gas 1/2" (15 mm) 3/4" (22 mm) 1" (28 mm)

1.1 Gas Connections (cont.)
DANGER
All connections must be sealed with a joint compound suitable for the gas being
used and all connections must be tested with a solution of soapy water before
lighting any pilots.
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 appliance at the main shut-off
valve and immediately contact the local gas company or an authorized service
agency for service.
DANGER
"Dry-firing" your unit will cause damage to the frypot and can cause a fire. Always
ensure that melted shortening, cooking oil or water is in the frypot before firing the
unit.
B. Rigid Connections: Check any installer-supplied intake pipe(s) and clean threading chips, or
any other foreign matter before installing into a service line. If the intake pipes are not clear
of all foreign matter, the orifices will clog when gas pressure is applied. Seal pipe joints
with a sealant resistive to LP gas. When using thread compound on gas piping, use very
small amounts and only on male threads. Use a pipe thread compound that is not affected
by the chemical action of LP gases. DO NOT apply thread compound to the first two pipe
threads—doing so will cause clogging of the burner orifices and control valve.
C. Manual shut-off valve: This gas service supplier-installed valve must be installed in the gas
service line ahead of the fryers in the gas stream and in a position where it can be reached
quickly in the event of an emergency.
D. Regulating Gas Pressure: The fryer and shut-off valve must be disconnected from the gas
supply during any pressure testing of the system.
1. External gas regulators are not normally required on this fryer. A safety control valve
protects the fryer against pressure fluctuations. If the incoming pressure is in excess of
½PSI (3.45 kPa/35 mbar), a step-down regulator will be required.
DANGER
When pressure-testing incoming gas supply lines, disconnect the fryer from the gas
line if the test pressure is ½ PSI [3.45 kPa (14 inches W.C.)] or greater to avoid
damage to the fryer’s gas piping and gas valve(s).

1.1 Gas Connections (cont.)
E. Manifold Pressure: Only qualified personnel should check the manifold pressure with a
manometer.
1. Check the rating plate for manifold gas pressures. Natural gas units normally require 4"
W.C., and propane units normally require 11" W.C. gas pressure.
2. Double check the arrow forged into the bottom of the regulator body, which indicates
gas flow direction. It should point downstream towards the fryers. The air vent cap is
also part of the regulator and should not be removed.
3. If a vent line from the gas pressure regulator is used, it should be installed in
accordance with local codes or in the absence of local codes, with the National Fuel
Gas Code, ANSI Z223.1-(latest edition).
WARNING
Use a diluted soap solution to find potentially dangerous gas leaks when making
new connections.
F. Regulators can be adjusted in the field, but it is recommended that they not be tampered with
unless the part is known to be out of adjustment or serious pressure fluctuations are found to
exist and can be solved no other way.
G. Only qualified service personnel should make adjustments to the regulators.
H. Orifices: The fryer can be configured to operate on any available gas. The correct safety
control valve, appropriate gas orifices, and pilot burner are installed at the factory. While the
valve can be adjusted in the field, only qualified service personnel should make any
adjustments with the proper test equipment.
I. Flexible Couplings, Connectors and Casters:
1. If the fryer is to be installed with flexible couplings and/or quick-disconnect fittings, the
installer must use a heavy-duty AGA design-certified commercial flexible connector of
at least 3/4" NPT (with suitable strain reliefs), in compliance with the Standard for
Connectors for Movable Gas Appliances, ANSI Z21.69-(latest edition) and Addenda
Z21.69a-(latest edition). Quick disconnect devices must comply with the Standard for
Quick-Disconnect Devices for Use with Gas Fuel, ANSI Z21.41-(latest edition).
WARNING
Do not attach accessories to this fryer unless fryer is secured from tipping. Personal
injury may result.
2. The fryer must be restrained by means independent of the flexible coupling or
connector in order to limit the movement of the fryer. Clips are located on the back
panel of the fryer for the attachment of restraints.

2.1 Initial Start-up
WARNING
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent hazards of operating a hot oil frying system, particularly the aspects of
system operation, oil filtration, draining and cleaning procedures.
A. Cleaning: New units are wiped clean with solvents at the factory to remove any visible signs
of dirt, oil, grease, etc. remaining from the manufacturing process, then coated lightly with
oil. Before any food preparation, wash thoroughly with hot, soapy water to remove any film
residue and dust or debris then rinse out and wipe dry. Also wash any accessories shipped
with the unit. Close the drain valve completely and remove the crumb screen covering the
heating tubes. Ensure the screws holding the thermostat and high-limit control sensing bulbs
into the frypot are tight.
WARNING
Do not bang fry baskets or other utensils on the fryer’s joiner strip. The strip is
present to seal the joint between the frypots. Banging fry baskets on the strip to
dislodge shortening will distort the strip, adversely affecting its fit. It is designed for
a tight fit and should only be removed for cleaning.
DANGER
Never operate this appliance with an empty frypot. The frypot must be filled with
water or cooking oil/shortening before lighting the burners. Failure to do so will
damage the frypot and may cause a fire.
WARNING
When checking for burner ignition or performance, do not get too close to the
burners. Slow ignition can cause possible flashback, increasing the potential for
facial and body burns.

2.2 Final Preparation
WARNING
Do not go near the area directly over the flue outlet while the fryer is operating.
Always wear oil-proof, insulated gloves when working with the fryer filled with hot
oil.
Always drain hot oil into a metal container. Hot oil can melt plastic buckets and
crack glass containers.
WARNING
NEVER set a complete block of solid shortening on top of the heating tubes. To do
so will damage the heating tubes and frypot, and void the warranty.
A. When using a liquid shortening (cooking oil), fill the fryer to ¼" below the top OIL LEVEL
line scribed into the back of the frypot.
B. When using a solid shortening, first melt it in a suitable container, or cut it into small pieces
and pack it below the heat tubes, between the tubes and on top of the tubes, leaving no air
spaces around the tubes. Do not disturb or bend the sensing bulbs. Never set a complete
block of solid shortening on top of the heating tubes. To do so will damage the heating
tubes and frypot, and void the warranty.
C. Press the switch to turn fryer on. The burners will initially operate in the MELT CYCLE
mode until the shortening reaches 180°F (82°C). It will then automatically switch to normal
operation.
D. When the frypot is filled and the shortening is melted, carefully replace the frypot crumb
screen over the heat tubes. Wear oil-proof insulated gloves to avoid the potential for burn
injury when replacing crumb screen.
E. Before starting operation, program the computer to the probable working temperature and
wait for the temperature to stabilize.

WARNING
Drawings and photos used in this manual are intended to illustrate operational,
cleaning and technical procedures and may not conform to on-site management
operational procedures.
WARNING
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent hazards of operating a hot oil filtration system, particularly the aspects
of oil filtration, draining and cleaning procedures.
WARNING
When operating the filtration system, never leave the filter unattended. The action of
the oil moving through the hose lines could jolt a flexible return hose (where
applicable) out of the filter pan, spraying hot oil and causing severe burns.
DANGER
The crumb tray in fryers equipped with a filter system must be emptied into a
fireproof container at the end of frying operations each day. Some food particles
can spontaneously combust if left soaking in certain shortening material.
IMPORTANT
Cooking oil/shortening should be filtered at least daily, or more frequently if cooking
is heavy. This assures the longest life possible for the oil and minimizes flavor
transfer.
