2.0 INSTALLATION

WARNING: Do not connect the appliance to the electrical supply until after the gas connection has been made.

Installation must conform to local codes, or in absence of local codes, with the National Fuel Gas Code - ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code, CSA B149.1, as applicable.

1.The appliance and its individual shut off valve must be disconnected from the gas supply piping system during any pressure testing of that system at pressures in excess of ½ psi (3.5 kPa).

2.The appliance must be isolated from the gas supply piping system by closing its individual manual shut off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ psi (3.5 kPa).

Electrical grounding must be provided 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.

Ventilation must be provided in accordance with local codes, or in the absence of local codes, with ANSI/NFPA 96 Standard for Ventilation and Fire Protection of Commercial Cooking Operations.

WARNING: 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. (120V units only).

2.0INSTALLATION (Continued)

2.1EXHAUST FANS AND CANOPIES:

Canopies are set over ranges, ovens, kettles, etc., for ventilation purposes. It is recommended that a canopy extend 6" past the appliance and be located 6'-6" from the floor. Filters should be installed at an angle of 45 degrees or more with the horizontal. This position prevents dripping of grease and facilitates collecting the run-off grease in a drip pan, usually installed with the filter. A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance or may extinguish pilot flames. Makeup air openings approximately equal to the fan area will relieve such vacuum. In case of unsatisfactory performance on any appliance, check with the exhaust fan in the “OFF” position.

2.2 WALL EXHAUST FAN:

The exhaust fan should be installed at least two feet above the vent opening at the top of the unit.

2.3 CLEARANCES:

Adequate clearance must be provided in aisle and at the side and back. Adequate clearances for air openings into the combustion chamber must be provided, as well as for serviceability for use on noncombustible floors. Minimum clearance from combustible and noncombustible construction, 0" on left side, 0" on right side and 6" from back.

WARNING: These procedures must be followed by qualified personnel or warranty will be voided. An open gap floor drain is required immediately below the appliance drain.

2.0 INSTALLATION (Continued)

To Install:

1.Uncrate carefully. Report any freight damage to the freight company immediately.

2.Set the unit in place. Be certain to maintain the minimum clearances from combustibles and non-combustibles.

3.For an appliance supplied with legs, level the appliance using a spirit level. Should flanged adjustable feet be provided, anchor to floor using proper anchoring devices.

4.Seal bolts and flanged feet with Silastic or other equivalent compound.

5.Be certain to leave adequate clearances for cleaning, maintenance and service.

WARNING: For an appliance equipped with casters, the installation shall be made with a connector that complies with the standard for connectors for moveable gas appliances, ANSI Z21.69-CSA 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; adequate means must be provided to limit the movement of the appliance without depending on the connector and the quickdisconnect device or its associated piping to limit the appliance movement; the location where the restraining means may be attached to the appliance is on bottom of unit directly below relief valve.

If the unit is also equipped with an optional water fill valve it too must be installed with a flexible water supply tube, a quick disconnect and strain relief.

GAS CONNECTION:

CAUTION: The pipe thread compound used when installing pipes must be a type that is resistant to the action of liquified petroleum or propane gases.

NOTICE: If this equipment is being installed at over 2,000 feet altitude and was not so specified on order, contact service department. Failure to install with proper orifice sizing may void the warranty.
