ASSEMBLY
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.
FLUE CONNECTION
Make the flue connection as follows:
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 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 flue of combustibles or ventilation exiting from the fryer flue. DO NOT put
anything on top of flue area.
ELECTRICAL CONNECTION
Electrical Grounding Instructions:
This appliance is equipped with a three prong (grounding) plug for your protection
against shock hazard and should be plugged directly into a properly grounded
three-prong receptacle. Do not cut or remove the grounding prong from this plug.
Fryer must be electrically grounded in accordance with local codes, or in the
absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the
Canadian Electrical Code, CSA C22.2, as applicable.

GAS CONNECTION
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 and 1-1/4” (31.75 cm) iron pipe for batteries.
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 measured exiting the gas valve should be set at 3.5” W.C. (Water Column)
(0.87kPa) for natural gas and 10”W.C. (2.49 kPa) for propane gas. The supply pressure
should be 7-9” W.C. for natural gas and 11-12” W.C. for propane gas. If incoming pressure
exceeds 14” WC (½ psig -3.45 kPa), a step-down pressure regulator must be installed.
TESTING THE GAS SUPPLY PIPING SYSTEM:
When test pressures exceed ½ psig (3.45 kPa), the fryer and its individual shutoff valve
must be disconnected from the gas supply piping system.
When test pressures are ½ psig (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:
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, 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.CSA 6.9 or Quick-
Disconnect Devices for Use with Gas Fuel.

VHG SERIES GAS FRYERS
VULCAN F-47678 Rev. A (3-20)

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 quick disconnect
from being strained. The restraining device should be attached to the cutout on the
back panel. See illustration for location.
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. If
disconnection of the restraint is necessary, reconnect this restraint after the fryer
has been returned to its originally installed position.
LEVELING THE FRYER
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.
