Do not use the door or its handle to lift the fryer.
Before installing the fryer, verify that the type of gas (natural or propane) agrees with the
specifications on the fryer data plate, which is located on the inside of the door panel.
Make sure the fryer is configured for the proper elevation.
Record your fryer model, device, and serial numbers for future reference in the space
provided below. This information can be found on the fryer data plate.
Fryer Model No: ___________________________
Device: ___________________________________
Serial No: ________________________________
Clearances
Minimum clearance from combustible construction:
6” (15 cm) from the sides of the fryer
6” (15 cm) from the back of the fryer
The fryer may be installed on combustible floors
Minimum clearance from noncombustible construction:
0” from the sides of the fryer
0” from the back of the fryer
Between the fryer and any open-top flame units:

Allow space for servicing and operation.
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
open windows next to sides or back.

GRDF / GRCF SERIES GAS FRYERS
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. 02169-7471.
National Electrical Code, ANSI/NFPA-70 (latest edition). Copies may be obtained
from The National Fire Protection Association, Batterymarch Park, Quincy,
MA. 02169-7471.
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 Installation (latest edition).
CAN/CSA-B149.2 Propane Installation Code (latest edition), available from the
Canadian Gas Association 178 Rexdale Blvd., Etobicoke, Ontario Canada
M9W 1R3.
CSA C22.1 Canadian Electric Code L4W 5N6.
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.

GRDF / GRCF SERIES GAS FRYERS
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.
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.
Electrical diagram located on inside of door.
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.

GRDF / GRCF SERIES GAS FRYERS
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:
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 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.
VULCAN-HART F-32933 Rev. J (August 2012)

GRDF / GRCF SERIES GAS FRYERS
In Australia, use only the caster supplied by the manufacturer for the fryer
device. The fryer must be installed using a hose assembly restraining device to
limit the movement of the appliance in accordance with AS1869.
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.
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 power up 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.
