Installation, Operation and Care Of
MODEL GH SERIES HEAVY DUTY GAS RANGES
PLEASE KEEP THIS MANUAL FOR FUTURE REFERENCE
GENERAL
Vulcan ranges and ovens are produced with quality workmanship and material. Proper installation,
usage and maintenance of your range will result in many years of satisfactory performance.
The manufacturer suggests that you thoroughly read this entire manual and carefully follow all of the
instructions provided.
INSTALLATION
UNPACKING
This range was inspected before leaving the factory. The transportation company assumes full
responsibility for safe delivery upon acceptance of the shipment. Immediately after unpacking, check
for possible shipping damage. If the range is found to be damaged, save the packaging material and
contact the carrier within 15 days of delivery.
Carefully unpack range(s) and place in the approximate installation position, whether as a battery or
single stand-alone range. Remove all shipping wire and wood blocking. Remove parts (packed in a
cardboard box) from oven cavity, or cabinet body, or on top of modular range(s).
Before installing, check the electrical service (Convection Oven Models only) and type of gas supply
(natural or propane) to make sure they agree with the specifications on the rating plate located on the
lower left-hand corner of the front frame behind the bellcrank. If the supply and equipment
requirements do not agree, do not proceed with the installation. Contact your dealer or Vulcan-Hart
Company immediately.
LOCATION
CAUTION: The equipment area must be kept free and clear of combustible substances.
The following ranges, when installed, must have a minimum clearance from combustible construction
of 6" (15 cm) at the sides and 6" (15 cm) at the rear. Clearance from non-combustible construction can
be 0" (0 cm) at the sides and rear:

Ranges must not be included in back-to-back setups.
The following ranges are to be installed only on non-combustible floors:

GHM45 GHXM45 GHM45/72 GHM3/72 GHM6
GHM30 GHXM60 GHM60/72
The installation location must allow adequate clearances for servicing and proper operation. A
minimum front clearance of 35" (88 cm) is required.
The range(s) 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(s) must be provided. Make sure
there is an adequate supply of air in the room to allow for combustion of the gas at the burners.

ASSEMBLY
Ranges Mounted on Casters
When ranges are mounted on casters, you must use a connector (available from Vulcan-Hart) that
complies with the Standard for Connectors of Movable Gas Appliances, ANSI-Z21.69 (latest edition),
and a quick-disconnect device that complies with the Standard for Quick-Disconnect Devices
Complying With Gas Fuel, ANSI-Z21.41 (latest edition) or CAN 1-6.9 (latest edition).
Provide a gas line strain relief to limit movement of the range(s) without depending on the connector
and/or any quick-disconnect device or its associated piping to limit movement of the range(s). Attach
the strain relief to the rear of the range (Fig. 1).

Should it be necessary to disconnect the strain relief, turn off the gas supply before disconnection.
Reconnect the strain relief before turning the gas supply on and returning the range(s) to their
installation position.
Bumper Bars
CAUTION: Failure to install bumper bars may cause motor damage and will void the warranty.
Remove existing #10 screws. Position bumper bars as shown in Fig. 2. Replace #10 screws and secure
bumper bars.
