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 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).
