In Canada:
Local codes
CAN/CSA-B149.1 Natural Gas and Propane Installation Code (latest
edition),available from the Canadian Standards Association, 155 Queen Street,
Suite 1300, Ottawa, Ontario Canada K1P 6L1.
CSA C22.1 Canadian Electric Code (latest edition), available from the Canadian
Standards Association, 155 Queen Street, Suite 1300, Ottawa, Ontario Canada
K1P 6L1.
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 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.
GRMF SERIES GAS FRYERS
VULCAN-HART F-31233 Rev. T (12-15)
-8-
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 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, CAN/CGA-
6.16, and a quick-disconnect device that complies with the Standard for QuickDisconnect Devices for Use with Gas Fuel, ANSI z21.41 CSA 6.9 or QuickDisconnect Devices for Use with Gas Fuel,
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.
GRMF SERIES GAS FRYERS
VULCAN-HART F-31233 Rev. T (12-15)

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, to 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.
Lock the wheels after unit is level.
OPERATION
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.
