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.

w NFPA Standard #96 Vapor Removal from Cooking Equipment, latest edition,

available from the National Fire Protection Association, Batterymarch Park, Quincy,

MA.

WOLF WF FRYERS

WF Series Fryers WF-53700 Rev. A (7-23)

-8-

w 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:

w Local codes

w 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.

w CSA C22.1 Canadian Electric Code L4W 5N6.

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 EXHAUST

w 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.

w 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.

w Clearance above the fryer should be adequate for combustion byproducts

to be removed efficiently.

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.

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:

w The installation shall be made with a connector that complies with the

Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 or Connectors

WOLF WF FRYERS

WF Series Fryers WF-53700 Rev. A (7-23)

-10-

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.

w 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.

w The fryer must be installed with a connector (not supplied by Wolf) complying with

the above codes.

w The fryer must be installed with restraining means to guard against transmission

of strain to the connector. See illustration.

w The fryer must be installed with the casters provided.

w If the restraint is ever to be disconnected, first turn the gas supply off.

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.

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.

OVER-TEMPERATURE SHUTDOWN

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 Wolf authorized service office.

cleaning, and servicing the fryer.

w Filter shortening at least once a day. Refer to the instructions provided

with your filtering equipment.

w A cold fryer will not drain properly. Always filter shortening between 250°F

and 350°F. The shortening in the cold zone area will remain hard if the heat is only

on for a few minutes. If necessary, use the clean-out rod to carefully stir the hard

shortening to an area above the cold zone where it will melt. Use the tank brush to

help clear sides and tubes of debris.

CLEANING

Hot oil and hot parts can cause burns. Use care when operating,

cleaning, and servicing the fryer.

Daily

Clean your fryer regularly with the tank brush along with a damp cloth, and polish with a soft

dry cloth. If regular cleaning is neglected, grease will be burned on and discolorations may

form.

Fingerprints are sometimes a problem on highly polished surfaces of stainless steel. They

can be minimized by applying a cleaner that will leave a thin oily or waxy film.

w Clean all exterior surfaces of your fryer at least once daily.

w Use a damp cloth with warm water and a mild soap or detergent.

Do not use chlorine or sulfate/sulfide cleaners.

w Rinse thoroughly, and then polish with a soft dry cloth.

w Keep the fryer exterior clean and free of accumulated grease to prevent

stubborn stains from forming. If regular cleaning is neglected, grease will be burned

on and discolorations may form.

w Remove discolorations by washing with any detergent or soap and water.

w Use a self-soaping, non-metallic scouring pad for particularly stubborn

discolorations.

w Always rub with the grain of the stainless steel.

WOLF WF FRYERS

WF Series Fryers WF-53700 Rev. A (7-23)

-17-

w Do not use a metallic scoring pad or harsh cleaners.
