Fryers Mounted on Optional Casters
Fryers mounted on casters must use a flexible
connector (NOT SUPPLIED BY VULCAN) that
complies with the Standard for Connectors of
Movable Gas Appliances, ANSI-Z21.69 • CSA6.16
and a quick-disconnect device that complies with
the Standard for Quick-Disconnect Devices for
Use With Gas Fuel, ANSI-Z21 • CSA6.9.
In addition, adequate means must be provided to
limit the movement of the appliance without depending
on the connector and the quick-disconnect device
or its associated piping to limit the appliance
movement. Attach the restraining device to the rear
Fig. 1
of the fryer as shown in Fig. 1.
If it is necessary to disconnect the restraint, turn off the gas supply before disconnection. Reconnect
the restraint before turning the gas supply on and returning the fryer to its installation position.
Instructions for installing casters to the fryer are included with the casters.
LEVELING THE FRYER
Stand Alone Installations
Once gas connections have been made, place a spirit level on top of the fryer. Adjust the legs to ensure
that the fryer is level front-to-back and side-to-side in the final installed position.
Battery Installations
When the fryer is part of a battery lineup, line the fryer up front-to-back and side-to-side with adjacent
battery equipment. Equipment front tops and manifold pipes must be aligned with adjacent equipment.
Once the fryer is in its exact location in the battery lineup, place a spirit level on top of the fryer. Adjust
the legs to ensure that the fryer is level front-to-back and side-to-side in the final installed position.
GAS CONNECTIONS
CAUTION: All gas supply connections and any pipe joint compound used must be resistant
to the action of propane gases.
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR
LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
Rear Gas Connection for Stand Alone Installations
The gas inlet is located at the lower left rear.
Codes require that a gas shutoff valve be installed in the gas line ahead of the fryer.
The gas supply line must be at least the equivalent of
disconnect flex hose,
3
/4" (19 mm) iron pipe must be used unless 3/4" (19 mm) to 1/2" (12.7 mm) reducing
1
/2" (12.7 mm) iron pipe. If using the optional quick-
fittings are used. Make sure the pipes are clean and free of obstructions, dirt, and piping compound.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.

Front Gas Connection for Battery Installations
Codes require that a gas shutoff valve be installed in the gas line ahead of the fryer and battery of
equipment.
The gas manifold of a battery lineup of which the fryer is a part, must be installed using a regulator
design-certified by a nationally recognized testing lab to the applicable ANSI standard (regulators
available from Vulcan-Hart). The pressure regulator must have a maximum regulation capacity to
handle the total connected load and must have an adjustment range for manifold pressure marked on
the equipment rating plate(s). If the manifold pressure of the connected equipment is not the same, a
separate regulator must be supplied for all devices operating under different manifold pressure ratings.
Set all fryers in line with each other and adjacent ranges (16" [40 cm] clearance required between fryer
and open top flame units). Remove control panels for access to union connections or manifold pipes.
Screw each union finger-tight to adjoining connection. Do not overtighten. Tighten each union,
ensuring that the gas manifold is not pulled to the left or right by overtightening the unions. When all
fryers in the battery are connected finger-tight, then tighten with a pipe wrench. Always use pipe joint
compound that is resistant to the action of liquid petroleum gases on unions.
TESTING THE GAS SUPPLY SYSTEM
When test pressures exceed
1
/2 psig (3.45 kPa), the fryer and its individual shutoff valve must be
disconnected from the gas supply piping system.
1
When test pressures are
/2 psig (3.45 kPa) or less, the fryer must be isolated from the gas supply
system by closing its individual manual shutoff valve.
FLUE CONNECTIONS
DO NOT obstruct the flow of flue gases from the flue located at the rear of the fryer. It is recommended
that the flue gases be ventilated to the outside of the building through a ventilation system installed by
qualified personnel.
Adequate ventilation must be provided and must comply with NFPA Standard #96 (latest edition), and
with local codes.
Never make flue connections directly to the fryer.
The fryer must be located under a hood which has an adequate connection to an exhaust duct. The
hood must extend 6" (152.4 mm) beyond fryer sides.
Clearance above fryer should be adequate for products of combustion to be removed efficiently. An
18" (457 mm) minimum clearance should be maintained between the flue vent and the filters of the hood
venting system.
Information on the construction and installation of ventilating hoods may be obtained from the standard
for "Vapor Removal from Cooking Equipment," NFPA No. 96 (latest edition), available from the National
Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
Adequate air should be provided in the kitchen to replace air taken out by the ventilating system. This
will prevent fryer function from being affected by a reduced atmospheric pressure.

OPERATION
WARNING: HOT OIL AND PARTS CAN CAUSE BURNS. USE CARE WHEN OPERATING,
CLEANING AND SERVICING THE FRYER.
WARNING: SPILLING HOT OIL CAN CAUSE SEVERE BURNS. DO NOT MOVE FRYER
WITHOUT DRAINING ALL OIL FROM THE TANK.
Tank warranty may be voided by improper operation. Turn gas valve off when draining or filling.
BEFORE FIRST USE
Cleaning
Using a non-corrosive, grease-dissolving commercial cleaner, clean the protective metal oils from all
surface parts and the fry tank interior. Follow the cleaner manufacturer's directions. Drain through the
valve in the bottom. Rinse thoroughly and drain. Be sure to remove all traces of cleaner; it can affect
the food taste. Wipe fry tank completely dry with a soft clean cloth.
Clean all fryer accessories. Rinse all parts thoroughly and wipe dry.
Seasoning
Light seasoning of the backsplash area is required to avoid possible surface corrosion. With a soft,
lint-free cloth, apply a thin layer of cooking oil over entire backsplash area. This should also be done
after every cleaning.
FILL FRY TANK WITH LIQUID SHORTENING
CAUTION: Before turning the burners on, the fry tank must be filled with liquid shortening.
If this is not done, the tank walls can be damaged. Warpage can cause leaks.
DO NOT melt solid shortening in the fry tank. The fry tank will be damaged and the shortening will
be scorched. Melt solid frying compound in a separate container, being careful to just melt and not
overheat it; then carefully pour into fry tank.
Keep shortening between the MIN and MAX lines in the fry tank. DO NOT add shortening beyond the
MAX line.
Shortening expands when heated. Adding shortening beyond the MAX line may cause an overflow of
hot shortening.
Add fresh liquid frying compound as needed.
