INSTALLATION INSTRUCTIONS UNPACKING

IMMEDIATELY INSPECT FOR SHIPPING DAMAGE
Immediately after unpacking the appliance, check for possible shipping damage. If the gas fired tilting skillet is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery. Prior to installation, verify that the type of gas supply (natural or propane) and electrical service agree with the specifications on the rating plate located on the left side panel as you face the front of the appliance. If the supply and equipment requirements do not agree, contact your dealer immediately.

Installation Codes and Standards
Installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1INFPA 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 1/2 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 1/2 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.

Flue Connections
Do not obstruct the flow of flue gases from the flue duct located on the rear of the gas-fired tilting skillet. It is recommended that the flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel. Information on the construction and installation of ventilating hoods may be obtained from the standard for “Vapour Removal from Cooking Equipment”, NFPA No. 96 (latest edition), available from the National Fire Protection Association, Batterymarch Park, Quincy, MA, 02269.

Location
The equipment must be kept free and clear of combustible substances. The appliance, when installed, must have minimum clearance from combustible and non-combustible construction of 0” (0 mm) from the sides and 6” (152 mm) from the rear. The appliance is intended for use on non-combustible floors. The installation location must allow adequate clearances for servicing and proper operation. A minimum front clearance of 36” (914 mm) is required. The appliance must be installed so that the flow of combustion and ventilation air will not be obstructed. Adequate clearance for air openings into the combustion chamber must be provided. Make sure there is an adequate supply of air in the room suitable for the amount of combustion gas feeding the braising pan burners. Do not permit fans to blow directly at the appliance, and wherever possible, avoid open windows next to the appliance. Avoid wall-type fans which create air cross-currents within the room.

Leveling and Anchoring

1. Set the appliance in place and level left to right and front-to-back using a spirit level.
2. Mark hole locations on the floor through anchoring holes provided in flanged adjustable feet.
3. Remove the appliance and drill holes in locations marked on the floor and insert proper anchoring devices (not supplied).
4. Set unit back in position and re-level left to right and front to back.
5. Bolt and anchor appliance securely to the floor.
6. Seal bolts and flanged feet with Silastic or equivalent compound.

Gas Connections

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

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. All gas supply connections and any pipe joint compound used must be resistant to the action of propane gases.
The gas inlet is located under the control panel on the left-hand side.
Connect gas supply to the tilting braising pan. The gas supply line must be at least the equivalent of 3/4” iron pipe with an incoming pressure of approximately 7” W.C. (Water Column) for natural gas or 11” W.C. (Water Column) for propane gas. Make sure the pipes are clean and free of obstructions, dirt and piping compound. Codes require that a gas shutoff valve be installed in the gas line ahead of the tilting braising pan. Natural gas and propane gas braising pans are equipped with fixed orifices and no adjustment is necessary. Gas burner manifold is set at 3.5” W.C. (Water Column) for natural gas, and 10” W.C. (Water Column) for propane gas.

WARNING
Never use an open flame to check for gas leaks. Check all connections for leaks using soapy water before use. After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
