THE INSTALLATION, OPERATING AND MAINTENANCE

INSTRUCTIONS THOROUGHLY BEFORE INSTALLING OR

SERVICING THIS EQUIPMENT.

Clearances listed in this manual apply to combustible and non-combustible materials. H Series Gas Range clearances are now 9" at the sides and 6" at the rear.

If machine is equipped with casters, the installer must provide a restraining device for the gas line to limit movement of the equipment without depending on the connector and/or any quick-disconnect device or its associated piping to limit movement of the equipment. Attach the restraining device to the rear of the machine where shown below.

IMPORTANT NOTES FOR ALL VULCAN APPLIANCES

1. These units are produced with the best possible workmanship and material. Proper installation is vital if best performance and appearance are to be achieved. Installer must follow the installation instructions carefully.

2. Information on the construction and installation of ventilating hoods may be obtained from the "Standard for the installation of equipment for the removal of smoke and grease laden vapors from commercial cooking equipment," NFPA No. 96 (latest edition) available from the National Fire Protection Association, Battery March Park, Quincy MA 02269.

3. For an appliance equipped with a flexible electric supply cord, the cord is equipped with a three prong (grounding) plug. This grounding plug is 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. If the appliance is not equipped with a grounding plug, and electric supply is needed, ground the appliance by using the ground lug provided (refer to the wiring diagram).

(FOR GAS APPLIANCES ONLY)

4. Do not obstruct the air flow into and around the appliance. This air flow is necessary for proper combustion of gases and for ventilation of the appliance. Provisions for ventilation of incoming air supply for the equipment in the room must be in accordance with National Fuel Gas Code ANSI Z223.1 (latest edition).

5. Do not obstruct the flow of flue gases from the flue duct (when so equipped) located on the rear (or sides) of the appliance. It is recommended that the flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel.

6. For an appliance equipped with casters, (1) the installation shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 (latest edition), and Addenda, Z21.69a (latest edition), and a quick-disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI Z21.41 (latest edition), and Addenda, Z21.41 a (latest edition) and Z21.41 b (latest edition), and (2) adequate means must be provided to limit the movement of the appliance without depending on the connector and the quick-disconnect device or its associated piping to limit the appliance movement. If disconnection of the restraint is necessary, reconnect this restraint after the appliance has been returned to its originally installed position.

7. The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 k Pa).

8. The appliance must be isolated from the gas supply system by closing its individual manual shutoff valve during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psig (3.45 k Pa).

CAUTIONS

FOR YOUR SAFETY DO NOT STORE OR USE GASOLINE OR OTHER FLAMMABLE VAPORS AND LIQUIDS IN THE VICINITY OF THIS EQUIPMENT OR ANY OTHER APPLIANCE.

1. KEEP THE APPLIANCE FREE AND CLEAR FROM ALL COMBUSTIBLE SUBSTANCES.

2. IN THE EVENT A GAS ODOR IS DETECTED, SHUT UNIT(S) DOWN AT THE MAIN SHUTOFF VALVE AND CONTACT THE LOCAL GAS COMPANY OR GAS SUPPLIER FOR SERVICE.

3. POST IN A PROMINENT LOCATION, INSTRUCTIONS TO BE FOLLOWED IN THE EVENT THE SMELL OF GAS IS DETECTED. THIS INFORMATION MAY BE OBTAINED FROM A LOCAL GAS SUPPLIER.

UNCRATING INSTRUCTIONS

NOTES:

A. Pipe joint compounds used when connecting appliances to gas should be resistant to the action of L.P. Gases. B. Pipe joints should be tested for leaks with a soap and water solution before operating the unit. C. SG 7800 Ranges are 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.

D. Snorkel Range Ovens require a minimum of 6" clearance at the rear Snorkel Range Ovens may not be included in a back to back set up.

1. Uncrate units carefully and place in the approximate location they will occupy in the battery. Remove all shipping wire and wood blocking.

2. On hot, even heat, and open top ranges, remove top castings (A) and rear top plates (B). Identify top castings so they are replaced in the same positions and on same range as when received from factory.

MATERIALS. PROPER INSTALLATION IS VITAL IF BEST PERFORMANCE AND APPEARANCE IS T0 BE ACHIEVED. PLEASE FOLLOW THESE INSTRUCTIONS CAREFULLY. LETTERS (A, B, ETC.) IN THE FOLLOWING INSTRUCTIONS REFER TO THE INSTALLATION DRAWING. SEE INSERT A.

3. Remove oven bottom and baffles (C).

4. Remove upper manifold panel (D).

5. Removal of the shipping bracket (E) is necessary on the corner of the range where a high shelf support casting is to be bolted. On units equipped with a back guard it is not necessary to remove either shipping bracket as they will be used for support when remounting the rear top plate and back guard splasher back (step 12).

6. Place first appliance in exact position in battery and line up. If on "Standard " legs adjust leg heights by turning leg feet (P) until all contact the floor. If "Less Legs" or "On Toe Base" screw leveling bolts (F) down until bolts contact the floor. Using carpenter level, level up appliance from front to rear, also from side to side. This operation is one of the most important installation practices. No floor is level and variations of from one to three inches in a room is common. Unless appliances are level, difficulty will be encountered in lining up the manifold pipe (G) and appliances will not butt tightly.

UNIT INSTALLATION PROCEDURES

1. Move next appliance into position and level up as explained above. Engage union nut on manifold pipe with male fitting on next appliance and draw up union nut hand tight. Be sure appliances butt both front and rear. If manifolds do not line up, then ranges are not level. Do not adjust manifold brackets (H) to make manifolds line up, except in extreme cases, because this will cause gas valves not to line up perfectly with manifold cover holes. Bolt top frames together using 10-24 x 1/2" bolts (R) (Packed in cloth bag in range oven.)

2. Continue leveling up, connecting manifold pipe and bolting top frames of ranges together until all appliances in battery are connected, then tighten manifold unions gas tight. Use wrench to keep section of union assembled to pipe from rotating. Failure to do this may result in misalignment of valve stems.

3. Uncrate high shelves or back guards and remove splasher backs (J).

4. Place high shelf or back guard in position and bolt

5. Bolt high shelves together by bolting through shelf

6. Replace back tops (B) and splasher backs (J).

7. If front plates (N) do not line up perfectly, adjust be

Snorkel Range Ovens are supplied with a cord and grounding plug assembly and must be plugged into the proper receptacle before turning on gas.
