Minimum supply pressure is 6" W.C. for natural gas and 12" W.C. for propane.
Orifice sizes are for units installed at altitudes between 0 and 2000 feet above sea level.
Installation
Installation must conform with local codes, or in the absence of local codes, with the National Fuel
Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane
Installation Code, CAN/CGA-B149.2, as applicable.
These installation procedures must be followed by qualified personnel or warranty will be void.
Local codes regarding installation vary greatly from one area to another. The National Fire Protection
Association, Inc. states in its NFPA 96 latest edition that local codes are the “authority having jurisdiction”
when it comes to installation requirements for equipment.
Step #1: Unpack
**IMMEDIATELY INSPECT FOR SHIPPING DAMAGE
All containers should be examined for damage before and during unloading. The freight carrier has
assumed responsibility for safe transit and delivery. If damaged equipment is received, either apparent or
concealed, a claim must be made with the delivering carrier.
Apparent damage or loss must be noted on the freight bill at the time of delivery. The freight bill must then
be signed by the carrier representative (Driver). If the bill is not signed, the carrier may refuse the claim.
The carrier can supply the necessary forms.

Page 5
A request for inspection must be made to the carrier within 15 days if there is concealed damage or loss
that is not apparent until after the equipment is uncrated. The carrier should arrange an inspection.
Be certain to hold all contents plus all packing material.
1. Uncrate carefully. Report any hidden damage to the freight carrier IMMEDIATELY.
2. Do not remove any tags or labels until unit is installed and working properly.
All Propane (LP) Gas Fryers MUST HAVE AN APPLIANCE REGULATOR INSTALLED in
addition to the tank or stage regulator. IF A PROPANE FRYER IS INSTALLED WITHOUT
THE CORRECT PRESSURE REGULATOR PARTS WILL BE DAMAGE AND THE
WARRANTY WILL BE VOID.
The appliance regulator must be set to gas pressure between 11” W.C. and 12” W.C.
Note: There is a pressure regulator “built in” to the combination gas valve, if the incoming
pressure is at 10” W.C. or lower this “built in” regulator will act as a restriction and cause
incomplete combustion and sooting. If the gas pressure is above 12” W.C. damage could occur
to the “built in” pressure regulator and in that case it would have to be replace, this would not be
covered by the warranty.
Step #2: Install the Legs (or Casters) and Restraints
A set of legs or casters is packed with the fryer. Mounting fasteners are pre-
mounted on the base plates.
1. Raise fryer sufficiently to allow legs or casters to be screwed into the base plate.
For safety, “shore up” and support the fryer with an adequate blocking
arrangement strong enough to support the load.
2. Screw the four legs or casters to the plate on the bottom of the fryer. When
casters have been ordered, the casters having a locking-brake should be
attached under the front of the fryer.
3. Lower the fryer gently. Never drop or allow the fryer to fall.
4. Use a level to make sure that the fryer is level. Each caster, or the tubular-end
of each leg, can screwed in or out to lower or raise each corner of the fryer.
5. Attach restraints as required by local codes.
Unit must be level to assure maximum performance and proper ventilation. Improper leveling may void warranty.
When this appliance is installed with casters, it must be installed with the casters supplied, a connector
complying with either ANSI Z21.69 CSA 6.16 and a quick-disconnect device complying with ANSI Z21.41

Page 6
CSA 6.9. It must also be installed with restraining means to guard against transmission of strain to the
connector, as specified in the appliance manufacturer instructions.
When this appliance is installed with casters, it must be installed with the casters supplied, a connector
complying with either ANSI Z21.69 or CAN/CGA-6.16 and a quick disconnect device complying with
either ANSI Z21.41 or CAN1-6.9. It must also be installed with restraining means to guard against
transmission of strain to the connector, as specified in the appliance manufacturer's instructions.
All fryers must be restrained to prevent tipping in order to avoid the splashing of hot liquid. The means of
restraint may be the manner of installation.
Step #3: Flue Installation
1. Unpack the flue box and flue wrap
2. Slide the flue box over the flue and secure it with the two self-tapping screws using a 5/16” socket

Page 7
3. Slide the flue wrap over the flue. 4. Secure it with four self-tapping screws, two on the
back and one on each side using a 5/16” socket.
Step #4: Check Clearances and Ventilation
Select a firm, level location for your fryer. Leave clearance, whenever possible, so that access from the
rear is possible to permit cleaning. If the unit is to be set on non-combustible flooring, such as a concrete
slab, 3 inches minimum toe room must be provided to prevent restriction of the air opening in the bottom of
the unit.
There must be adequate clearance between fryer(s) and construction. Clearance must also be provided
in front for servicing and for operation.
Minimum Clearances from Combustible Construction:
Sides: Six (6) Inches
Rear: Six (6) Inches
ALL FRYERS SHALL BE INSTALLED WITH AT LEAST A 16 INCH SPACE BETWEEN THE FRYER
AND SURFACE FLAMES FROM ADJACENT EQUIPMENT. A FLAME GUARD IS ACCEPTABLE IF
ALLOWED UNDER LOCAL CODE.
“SUITABEL FOR INSTALLATION ON COMBUSTIBLE FLOORS”
No additional side and rear clearance is required for service as the fryer is serviceable from the front.
Improper ventilation can result in personal injury or death. Ventilation that fails to properly remove flue
products can cause headaches, drowsiness, nausea, or could result in death.
Unit Must be installed under a ventilation hood.

Page 8
All units must be installed in such a manner that the flow of combustion and ventilation air is not
obstructed. Provisions for adequate air supply must also be provided. Do NOT obstruct the bottom front
of the unit, as combustion air enters through this area. Be sure to inspect and clean the ventilation
system according to the ventilation equipment manufacturer’s instructions.
Due to the variety of problems that can be caused by outside weather conditions, venting by canopies or
wall fans is preferred over any type of direct venting. It is recommended that a canopy extend 6" past the
appliance and the bottom edge be located 6'6" from the floor. Filters should be installed at an angle of 45°
or more from the horizontal. This position prevents dripping of grease and facilitates collecting the run-off
grease in a drip pan, unusually installed with a filter. A strong exhaust fan tends to create a vacuum in the
room and may interfere with burner performance or may extinguish pilot flames. Fresh air openings
approximately equal to the fan area will relieve such a vacuum. In case of unsatisfactory performance on
any appliance, check the appliance with the exhaust fan in the “OFF” position. Do this only long enough to
check equipment performance, then turn hood back on and let it run to remove any exhaust that may have
accumulated during the test.
The exhaust fan should be installed at least 2 feet above the vent opening at the top of the fryer. Make sure
all ventilation meet local code requirement
This unit is not intended to be connected directly to an outside flue.
Step #5: Gas Connection
A 3/4" male NPT line for the gas connection is located near the lower right rear corner of the fryer. The
serial plate (located inside the front door of the fryer) indicates the type of gas the unit is equipped to burn
(natural gas or propane). The fryer should be connected ONLY to the type of gas for which it is equipped.
A circuit diagram is located inside the front door of the fryer.
All equipment is adjusted at the factory; however, pilot height should be checked at installation and
adjusted, if necessary.
For orifice sizes and pressure regulator settings, see the chart on page 4. If the fryer is being installed at
over 2,000 feet altitude and that information was not specified when ordered, contact the appropriate
authorized Service Representative or the Service Department. Failure to install with proper orifice sizing
will result in poor performance and may void the warranty.
If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in
accordance with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI
Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code, CAN/CGA-
B149.2, as applicable.
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas
necessary for satisfactory performance. A combination gas valve and pressure regulator, which is provided
with each unit, is set to maintain a 4" W.C. manifold pressure for natural gas or 10.0" W.C. manifold
pressure for propane gas. However, to maintain these conditions the pressure on the supply line, when all
units are operating simultaneously, should not drop below 7" W.C. for natural gas or 11" W.C. for propane
gas. Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems and affect
burner operating characteristics. A 1/8" tap to measure the manifold pressure is located on the combination
gas valve and on the burner manifold, which is on the burner manifold located directly below the burners
inside the cabinet.

Page 9
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.
It is recommended that an individual manual shutoff valve be installed in the gas supply line to the unit.
Use pipe joint compound that is suitable for use with both natural and LP gas on all threaded connections.
ALL PIPE JOINTS AND CONNECTIONS MUST BE TESTED THOROUGHLY FOR GAS LEAKS. USE
ONLY SOAPY WATER FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO CHECK
FOR GAS LEAKS. ALL CONNECTIONS MUST BE CHECKED FOR LEAKS AFTER THE UNIT HAS
BEEN PUT INTO OPERATION. TEST PRESSURE SHOULD NOT EXCEED 12" W.C.
THIS APPLIANCE AND ITS INDIVIDUAL COMBINATION GAS VALVE MUST BE DISCONNECTED
FROM THE GAS SUPPLY PIPING SYSTEM DURING ANY PRESSURE TESTING OF THAT SYSTEM
AT TEST PRESSURES IN EXCESS OF 14”WC (1/2 PSIG or 3.45 kPa).
If the incoming gas pressure is in excess of 14"WC (1/2PSI, 3.45 kPa), a proper step-down regulator will
be required.
Step #5: Gas Connection (Continued)
Connect the gas supply directly to the 3/4" male NPT connector located near the lower left rear
corner of the fryer. When tightening the supply pipe, be sure to hold the mating connector
extending from the unit securely with a wrench. This will prevent any damage or distortion to the
internal piping and controls of the unit.
Checking For Gas Leaks: Using a gas leak detector or a soapy water solution is recommended
for locating gas leaks. Matches, candle flame, or other sources of ignition shall not be used for
this purpose. Check entire piping system including the internal piping and Pipe Union inside of
the fryer for leaks. DO NOT use an open flame to check for leaks. Check all gas piping for
leaks with a soap and water solution before operating the unit.
After connecting the gas supply, check again that the fryer is level. Use a long spirit level four
ways; across the front and rear of the frypot, and along each edge.

Page 10
Do not restrict the flow of gas. Use only commercially approved gas appliance
connectors OR Flexible Hoses! Non-commercial connectors or Flexible hoses
will void your warranty.
