ASSEMBLY AND LEVELING

When you receive your fryer, it is completely assembled with the possible exception of the legs (or
casters) and the heat shield. In some cases, if you have purchased a multi-fryer unit, you may need to
assemble the system.

1.3.1

Leg/Caster Installation and Adjustment

Installing the legs and leveling the fryer is done with a 7/16" wrench, socket, and a large pair of water
pump pliers. The legs/casters must be installed to provide the necessary height to meet sanitation
requirements and assure adequate air supply to the burner. Attach the legs by performing the following
procedure.

a. Lay the fryer on its side being careful not to damage the flue

by pulling on it. Protect the outside of the fryer with
cardboard or a drop cloth when laying it down.

b

. Attach each leg/caster with the hex head cap screws sup-

plied with the fryer. Each leg/caster requires four 1/4-20 x
5/8" cap screws.

c

. Mount the screws from the inside of the fryer with the nut

on the outside. The nuts have lock washers attached to
them, therefore it is not necessary to use lock washers.

d

. When all four legs/casters are mounted, stand the unit up

being careful not to put too much weight on any one leg/
caster.

Adjust the height and level the fryer by adjusting the
leveling devices on the leg/caster with the water pump
pliers.

1.4

INSTALLATION

Although it is possible for you to install and set up your new fryer, it is STRONGLY recommended
that you have it done by qualified professionals. The professionals that install your new fryer will know
the local building codes and ensure that your installation is safe.

WARNING

The fryer must be properly restrained to prevent movement or tipping.

This
restraint must prevent the fryer from movements that would splash hot liquids
on personnel. This restraint may be any means (alcove installation, adequate
ties, or battery installation).

1.4.1 Installation Clearances

The fryer needs clearance around it for proper operation. Adequate clearances allow for servicing and
proper burner operation. The clearances shown below are for cooker installation in combustible and
non-combustible construction.

1.4.2

Gas Connection

Your fryer will give you peak performance when the gas supply line is of sufficient size to provide the
correct gas flow. The gas line must be installed to meet the local building codes or National Fuel Gas
Code (NFPA 54-Latest Edition) and ANSI Z223.1-Latest Edition Latest Edition. In Canada, install
the fryer in accordance with CAN/CGA-B149.1 or .2 and local codes.

1-3

L20-251 R3

Gas line sizing requirements
Fuel Gas Code, Appendix C,

can be determined by your local gas company by referring to National

Table C-4 (natural gas) and Table C-16 (propane). The gas line
needs to be large enough to supply the necessary amount of fuel to all appliances without losing
pressure to any appliance. Other factors that are used to determine the piping requirements are
BTU requirements of the appliances being connected and the length of pipe between the meter
(main shut off) and the appliances.

WARNING

NEVER supply the fryer with a gas that is not indicated on the data plate. Using
the incorrect gas type will cause improper operation. If you need to convert the
fryer to another type of fuel, contact your dealer.

1.4.2.1

Fuel Types - Each fryer is equipped to work with one type of fuel. The type of fuel with

which the appliance is intended to operate is stamped on the data plate attached to the inside of the door.

WARNING

DO NOT use an open flame to check for gas leaks!

1.4.2.2

Gas Line Connection - Connect the fryer to the gas supply line with a connector that
complies with the Standard for Connectors for Movable Gas Appliances (ANSI Z21.69-Latest
Edition)

. If you are installing a fryer with casters use a quick disconnect refer to the Quick Disconnect
installation instruction, 1.4.2.3. Connect the gas line to the fryer using a pipe joint sealant that is resistant
to liquefied petroleum. If the fryer was disconnected during the fuel line testing, use a solution of soap
and water to leak test the new connection.

NOTICE

NEVER use an adaptor to make a smaller gas supply line fit the cooker
connection.

This may not allow proper gas flow for optimum burner operation,

resulting in poor cooker performance.

1.4.2.3

Quick Disconnect Gas Connection - Gas fryers equipped with casters must be installed
with connectors that comply with the Standard for Connectors for Movable Gas Appliances, ANSI
Z21.69-Latest Edition, and Addenda Z21.69A-Latest Edition. This connection should include a
quick disconnect device that complies with the Standard for Quick Disconnect Devices for Use
With Gas Fuel , ANSI Z21.41-Latest Edition. When installing a quick disconnect you must also
install a means for limiting the movement of the fryer. This device will prevent the gas line or the
quick disconnect from being strained. The restraining device should be attached to the cooker on
the back panel as shown in the illustration. The quick disconnect, hose, and restraining device can
be obtained from your dealer.

L20-251 R3

1.4.2.4

Fuel Supply Line Leak and Pressure Testing - The fuel supply system must be tested before

fryer is used.
If the fuel line is going to be tested at a pressure greater than (>)1/2 PSIG (3.45 kPa),

the fryer is disconnected from the fuel line. If the fuel line is to be tested at a pressure
less than (<) 1/2 PSIG (3.45 kPa), the fryer can be connected but the unit's gas valve must

make sure that

equal to or

be shut

Test all gas line connections for leaks with a solution of soap and water when pressure is applie d .

1.4.3

Ventilation and Fire Safety Systems

Your new fryer must have proper ventilation to function safely and properly. Exhaust gas temperatures
can reach as high as 1200°F (648°C). Therefore, it is very important to install a fire safety
system. Your ventilation system should be designed to allow for easy cleaning. Frequent cleaning
of the ventilation system and the fryer will reduce the chances of fire. Table 1-2 provides a list of
reference documents that provide guidance on ventilation and fire safety systems. This table is not
necessarily complete.
8501 East Pleasant Valley

Additional information can be obtained from the American Gas Association,

Road, Cleveland, OH 44131.

Excessive ventilation causes drafts, which will interfere with the proper operation of the pilot and
the burner. Leave at least 18 inches (45cm) of open space between the fryer's flue vent opening
and the intake of the exhaust hood.

CAUTION

Ensure that your ventilation system does not cause a down draft at the fryer's
flue opening. Down drafts will not allow the fryer to exhaust properly and will
cause overheating which may cause permanent damage. Damage caused by
down drafts will not be covered under equipment warranty. NEVER allow
anything to obstruct the flow of combustibles or ventilation exiting from the
fryer flue. DO NOT put anything on top of the flue area.

NOTICE

NEVER connect the blower directly to the flue openings. The direct flow of
air will cause poor temperature recovery, poor ignition, inefficient operation of
the fryer, and could extinguish the pilot.

1.5

INITIAL ADJUSTMENTS

After your fryer has been installed as described in section 1.4, it needs to be adjusted to ensure that it
will perform as designed. These adjustments must be performed by a qualified person. To perform
these adjustment the following tools will be needed:

• Manometer (low pressure gauge) • Digital Thermometer (Temperature probe)

• DC Millivolt Meter

Visual Checks

After the fryer is in its permanent location, lock the casters and check for levelness. Any additional
leveling that is necessary can be performed as described in section 1.3.

1.5.2

Burner Ignition Systems

CAUTION

Before going any further, fill the fryer with WATER. Water is used for the
installation adjustments because the temperature will never exceed 212°F
(100°C) thereby allowing plenty of adjustment time. Never let the water level
go below the MIN LEVEL mark on the rear of the tank.

WARNING

There is an open flame inside the fryer. The unit may get hot enough to set near
by materials on fire. Keep the area around the fryer free from combustibles.

1.5.2.1

Pilot Flame Adjustment - The pilot flame should be adjusted to produce the proper millivolt
output from the pilot sensing device. Millivolt output for the thermopile should be between 300 and
500 millivolts. This procedure is only necessary on the manual pilot ignition system. Figure 1-1 shows
the pilot assembly with examples of the incorrect and correct pilot s ize. Example A illustrates a pilot
flame size that is too small to produce sufficient millivolt output. Example B is the correct size for proper
millivolt output.

a

. This test requires a DC millivolt meter set to a scale of 0-1000mv.

b

. Locate the thermopile wires coming from th e thermostat/High Limit box going to the gas

shut off valve. The wire insulation size decreases near the gas valve connections.
