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 quick­disconnect 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)

CONNECTING UNIT TO GAS
BURNER & PILOT ADJUSTMENT

1. CONNECT UNIT TO GAS

Each unit is factory equipped for use with the type of gas
indicated on the range rating plate. Check type of gas supply
available.

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

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

4. If the pilot fails to light, turn off the gas, wait 5 minutes and
repeat steps 1 thru 3.

NIGHTLY SHUTDOWN

1. Turn the burner valve off, the pilot will remain lit.

SEASONAL SHUTDOWN

1. Turn the burner valve off, the pilot will remain lit.

2. Extinguish the pilot.

3. Turn the main gas supply off.

C. Standard units for use on Natural or Mixed Gases are
equipped with fixed orifices and pressure regulator with a pre­set outlet pressure of 3.7" W.C. (Water Column) Units for use on
propane gas are equipped with fixed orifices and pressure
regulator with a pre-set outlet pressure of 10.0" W.C.

2. PRESSURE REGULATOR
When connecting unit to gas supply, pressure regulator must be

mounted vertically as shown in Detail A to insure the proper
preset outlet pressure. If regulator is mounted in any other
position, the outlet pressure must be reset.

NOTE:
Do not obstruct leak limiter on gas pressure regulator.

3. BURNER AND PILOT ADJUSTMENTS
Standard units are equipped with a pressure regulator and

should require no further adjustments.

4. LIGHTING BROILER/GRIDDLE PILOT

1. Turn the main gas supply on.

2. Turn the burner valve on and purge air from lines
Turn the valve off.

3. Using a taper, light the pilot.

5. Pilot Adjustment—Turn one burner on to remove air from
the line. Turn burner off when gas begins to flow. Light top pilots

and adjust, if necessary, by rotating adjusting screw in pilot
valve on manifold. (Clockwise to decrease and counter­clockwise to increase flame.)

6. Burner Adjustment—The efficiency of the unit depends on
a rather delicate balance between the supply of air and volume
of gas so that complete combustion is achieved. Whenever this
balance is disturbed poor operating characteristics and ex­cessive gas consumption occur.

7. Air Supply—Is controlled by an air shutter on the front of the
burner. The air shutter on the front of the burner. The air shutter
openings should be increased until the flame on the burner
begins to "lift". The air shutter should then be closed slightly and
locked in place. A yellow streaming flame is an indication of
insufficient air. This condition can be corrected by increasing the
air shutter opening.
