Location
Install fryer in an area with sufficient air supply for gas combustion at fryer burners.
Do not obstruct the flow of combustion and ventilation air.
Provide adequate clearance for air openings into the combustion chamber.
Do not permit fans to blow directly onto fryer.
Avoid wall-type fans, which create cross-currents within a room. Avoid

4. Secure it with four self-tapping screws two on the back and one on each side using a
5/16” socket
The fryer must be installed in accordance with:
In the United States:
State and local codes, or in the absence of local codes, with:
National Fuel Gas Code, ANSI-Z223.1/NFPA #54 (latest edition). Copies may
be obtained from The American Gas Association Accredited Standards Committee
Z223, @ 400 N. Capital St. NW, Washington, DC 20001 or the Secretary Standards
Council, NFPA, 1 Batterymarch Park Quincy, MA 02169-7471.
NFPA Standard #96 Vapor Removal from Cooking Equipment, latest edition,
available from the National Fire Protection Association, Batterymarch Park, Quincy,
MA.
In the commonwealth of Massachusetts all gas appliances vented through a
ventilation hood or exhaust system with a damper or with a power means of exhaust
shall comply with 248 CMR.
In Canada:
Local codes
CAN/CSA-B149.1 Natural Gas and Propane Code Installation (latest edition),
available from the Canadian Gas Association 350 Sparks Street, Ottawa, Ontario
Canada K1R 7S8.
CSA C22.1 Canadian Electric Code L4W 5N6.
CODES AND STANDARDS

VULCAN LG FRYERS
The fryer must be restrained to prevent tipping and the splashing of hot liquid. The means
of restraint may be the manner of installation, such as connection to a battery of appliances,
installing the fryer in an alcove, or by separate means such as adequate ties.
Comply with Vapor Removal from Cooking Equipment, ANSI-NFPA
Standard #96 (latest edition), available from the National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269.
Locate the fryer under a hood with adequate connection to an exhaust
duct. The hood must extend 6” (15 cm) beyond fryer on both sides.
Clearance above the fryer should be adequate for combustion byproducts
to be removed efficiently.
An 18” (46 cm) minimum clearance should be maintained between the flue vent and
the filters of the hood venting system.
Never make flue connections directly to the fryer.
Do not obstruct the flow of the gases from the appliance. Proper air balance should
be maintained in the room.
Ensure that your ventilation system does not cause a down draft at the fryer’s flue
opening. Down draft will not allow the fryer to exhaust properly and will cause
overheating which may cause permanent damage. Damage caused by down draft
will not be covered under equipment warranty. Never allow anything to obstruct
the flue or ventilation exiting from the fryer flue. Do not put anything on top of flue
area.
All gas supply connections and any pipe joint compound must be
resistant to the action of propane gases.
The gas inlet is located on the lower rear of the fryer. 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 ½” (12.7 mm) iron pipe for single units
and 1-1/4” (31.75 mm) for batteries. If using the optional quick-disconnect flex hose, ¾” (19
mm) iron pipe for single units.

GAS CONNECTION

VULCAN LG FRYERS
Make sure the pipes are clean and free of obstructions, dirt, and piping compound. A
battery requires one or two connections of appropriate size for the gas requirement.
Prior to lighting, check all joints in the gas supply line for leaks.
Use soap and water solution. Do not use an open flame.
After piping has been checked for leaks, fully purge gas pipes to remove air.
GAS PRESSURES (ALL MODELS):
The gas pressure should be set at 4” W.C. (Water Column) (0.8 kPa) for natural gas and 10”
W.C. (2.75 kPa) for propane gas. If incoming pressure exceeds ½ PSI (3.45 kPa), an
additional pressure regulator must be installed.
TESTING THE GAS SUPPLY PIPING SYSTEM:
When test pressures exceed ½ PSI (3.45 kPa), the fryer and its individual shutoff valve must
be disconnected from the gas supply piping system.
When test pressures are ½ PSI (3.45 kPa) or less, the fryer must be isolated from the gas
supply piping system by closing its individual shutoff valve.
Fryers with Casters: (Restraining device does not come supplied with fryer or casters).
Separate instructions for installing casters are included with the casters:
The installation shall be made with a connector that complies with the
Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 or Connectors
for Moveable Gas Appliances, CAN/CGA-6.16, and a quick-disconnect device that
complies with the Standard for Quick-Disconnect Devices for Use with Gas Fuel,
ANSI z21.41 or Quick-Disconnect Devices for Use with Gas Fuel, CANI-6.9.
When installing a quick disconnect you must also install a means for limiting the
movement of the fryer. This restraining device will prevent the gas line or quick
disconnect from being strained. The restraining device should be attached to the
cutout on the back panel. See illustration for location. If disconnection of the
restraining device is necessary for service or cleaning, reconnect the restraining
device after the fryer is placed back into its original position.

VULCAN LG FRYERS
The fryer must be installed with a connector (not supplied by Vulcan) complying with
the above codes.
The fryer must be installed with restraining means to guard against transmission
of strain to the connector. See illustration.
The fryer must be installed with the casters provided.
If the restraint is ever to be disconnected, first turn the gas supply off.
Check the level of the fryer by placing a level on top of the fryer after gas connections have
been made.
Ensure that the fryer is level front-to-back and side-to-side in the final installed position.
If using casters, lock the wheels after unit is level.
Hot oil and parts can cause burns. Use care when operating,
cleaning and servicing the fryer.
Spilling hot frying compound can cause severe burns. Do not move
fryer without draining all frying compound from the tank.
LEVELING THE FRYER
OPERATION

VULCAN LG FRYERS
If the shortening becomes overheated, a high-temperature shutoff device will turn the gas
valve off and extinguish the pilot.
If the fryer shuts down due to overheating, DO NOT relight the pilot until the shortening
temperature is below 300° F (149 C).
If an overheating situation persists, contact your local Vulcan-Hart authorized service office.
Cleaning
New units are wiped down at the factory to remove any visible signs of dirt, oil, grease, etc.
remaining from the manufacturing process.
Before any food preparation, thoroughly wash the protective oil from all surface parts and
the tank interior with hot soapy water to remove any film residue and dust or debris.
Do not use chlorine or sulfate/sulfide cleaners.
Wash any accessories shipped with unit.
Rinse fryer and accessories thoroughly and drain the fryer.
Wipe tank completely dry with a soft, clean cloth.
Solid shortening should NOT be used with LG300 or LG400 fryers. Melting solid
shortening will damage the tank and void your warranty.
