CODES AND STANDARDS

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.

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

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.

GAS CONNECTION
NOTICE
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.
WARNIING
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.
A Rear of Fryer
B Strain Relief Chain Connection ( Chain supplied by others)
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.

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

WARNING

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 Vulcan-Hart authorized service office.

BEFORE FIRST USE

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.
NOTICE

Filter shortening at least once a day. Refer to the instructions provided with your filtering equipment.
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

WARNING
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.

Clean all exterior surfaces of your fryer at least once daily.
Use a damp cloth with warm water and a mild soap or detergent.

NOTICE

Do not use chlorine or sulfate/sulfide cleaners.
Rinse thoroughly, and then polish with a soft dry cloth.
Keep he 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.
Remove discolorations by washing with any detergent or soap and water.
Use a self-soaping, non-metallic scouring pad for particularly stubborn discolorations.
Always rub with the grain of the stainless steel.
Do not use a metallic scoring pad or harsh cleaners.
