Installation, Operation and Care of

MODELS MGR36 & MGR36C GAS DELI RANGES

SAVE THESE INSTRUCTIONS FOR FUTURE USE

GENERAL

Your MGR36 or MGR36C Gas Deli Range is equipped with six open top burners. The MGR36 range has a standard oven and is supplied with one oven rack. The MGR36C has a convection oven and is supplied with three oven racks. An additional oven rack for either model may be ordered as optional equipment.

INSTALLATION

UNPACKING

Immediately after unpacking the range, check it for possible shipping damage. If this range is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

Unpack range carefully and place it in a work-accessible area as near to its final installed position as possible. Remove all shipping wire and wood blocking.

Prior to installation, verify that the electrical service (convection ovens only) and type of gas supply (natural or propane) agree with the specifications on the data plate, which is located on the inside of the lower kick panel. If the supply and equipment requirements do not agree, do not proceed with the installation. Contact your local Hobart service office.

LOCATION

The equipment area must be kept free and clear of combustible substances. The range, when installed, must have a minimum clearance from combustible and non-combustible construction

of 6" at the sides and 6" at the rear. The installation location must allow adequate clearances for servicing and proper operation. A minimum front

clearance of 40" is required. The range 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 must be provided. Make sure there is an adequate supply of air in the room to allow for combustion of gas at the burners.

ASSEMBLY

Ranges Mounted on Casters

When the range is mounted on casters, you must use a flexible connector (not supplied) that complies with the Standard for Connectors of Movable Gas Appliances, ANSI-Z21.69 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). In Canada: When the range is installed with casters, it must be installed with the casters supplied, a connector complying with CAN/CGA-6.16 (latest edition), and a quick-disconnect device complying with CAN 1-6.9 (latest edition).

Provide a restraining device for the gas line to limit movement of the range without depending on the connector and/or any quick-disconnect device or its associated piping to limit movement of the range. Attach the restraining device to the rear of the range (Fig. 1).

If it becomes necessary to disconnect the restraint, turn off the gas supply before disconnection. Reconnect the restraint before turning the gas supply on and returning the range to its installation position.
