INSTALLATION, SERVICE & PARTS M7806/M7809

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 recepticle. 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, Z21.41a (latest edition) and Z21.41b (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.

INSTALLATION, SERVICE & PARTS M7806/M7809

INSTALLATION INSTRUCTION I - UNCRATING

Carefully uncrate unit as close to final resting place as
possible. Remove all shipping wire, wood blocking, top

INSTALLING UNIT

Place appliance in exact position it is to occupy. If unit is
to be used in battery, it is recommended that it be
installed on either end of the battery due to the intense
heat and adequate ventilation. Using a carpenter’s level,
even up appliances 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 and appliances will not butt tightly.

Move next appliance into position and level up as above
(when used on end of battery or when two or more units
are being installed). Engage union nut on manifold pipe
with male fitting on next appliance and draw union hand
tight. Be sure appliances butt both front and rear. If
manifolds do not line up, units are not level. Do not adjust
manifold brackets to make manifold line up, except in
extreme cases because this will cause gas valves not to
line up properly with manifold cover holes.

If unit is installed on end of battery and top of front top
does not line up with adjacent unit, adjust front tops by
means of bolts on the underside before replacing the
manifold cover and installing the valve handles.

The gas manifold of this appliance or battery of which it
is a part must be connected to a pressure regulator with
a pre-set outlet pressure of 6 in. W.C. (water column) for
natural gas and 10" W.C. for propane gas.

The pressure regulator must be A.G.A. design certified.
The regulator must have a maximum regulation capacity
to handle the total connected load and must have an
adjustment range for manifold pressure marked on the
rating plate, if the manifold pressure of the connected

grid grates, burner radiants, burners, manifold cover.
Grease collector and lower panel.

appliances are not the same, a separate regulator must
be supplied for units operating under different manifold
pressures.

NOTE: The unit and its individual shut-off 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.).

The appliance must also be isolated from the gas supply
piping system by closing it’s individual manual shut-off
valves during any pressure testing of the gas supply
piping system at test pressures equal to or less than

1

⁄2 PSIG (3.45L Pa.) as stated by the American National
Standards Z83,1 11a-1987 Copies of this Standard are
available from the American Gas Association, 1515
Wilson Blvd., Arlington, Virginia 22209.

Pipe joint compounds used when connecting appliances
to gas should be resistant to the action of L.P. gases.

Pipe joints should be tested for leaks with a soap and
water solution before operating the unit.

Continue to level up and connect manifold pipe until all
appliances in the battery are connected. Then tighten
manifold unions gas tight and connect to gas supply in
accordance with applicable local code.

Be sure all burner and pilot valves are in a closed
position. Turn on gas supply and check for leaks using a
soap and water solution or other acceptable methods
WARNING matches, candles or other sources of ignition
should not be used for this purpose.

Adjust burners making sure they line up with burner
nozzles and that all burner baffle plates are hanging in
the proper position.
