MODEL CMR34 GAS CHEESEMELTER

KEEP THIS MANUAL FOR FUTURE REFERENCE

GENERAL

Your Vulcan-HartGas Cheesemelter is suitable for use in restaurant, commercial or institutional kitchens. The cheesemelter is produced with quality workmanship and material. Proper installation, usage and maintenance of your cheesemelter will result in many years of satisfactory performance.

Vulcan-HartCompany suggests that you thoroughly read this entire manual and carefully follow all of the instructions provided.

CMR34 Cheesemelter Broilers are available in two styles:

1.Elevated Model — mounts over Heavy Duty Gas Range or Gas Restaurant Range (34" width minimum).

2.Free Standing Model — mounts on a non-combustiblecountertop with a 4" base stand.

INSTALLATION

Before installing, verify that the type of gas (natural or propane) agrees with the data plate on the body top of the cheesemelter.

UNPACKING

The cheesemelter was carefully 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 cheesemelter is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

LOCATION

Do not obstruct the air flow into and around the cheesemelter. This air flow is necessary for proper combustion of gases and for ventilation of the cheesemelter.

Do not obstruct the flow of flue gases from the flue duct of the cheesemelter. It is recommended that the flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel.

If mounted over a range equipped with casters, the minimum width of the range is 60 inches and the following restrictions apply:

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 a quick-disconnectdevice that complies with the Standard forQuick-DisconnectDevices for Use With Gas Fuel, ANSI Z21.41 (latest edition).

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

If disconnection of the strain relief is necessary, turn off the gas supply before disconnection. Reconnect this restraint before turning the gas supply on and returning the range to its installation position.

Standard cheesemelters for use with natural gas are equipped with fixed orifices and a pressure regulator with a preset outlet pressure of 6" W.C. (water column).

Standard cheesemelters for use with propane gas are equipped with fixed orifices and a pressure regulator with a preset outlet pressure of 10" W.C.

Once the regulator is installed, connect to a 3/4" gas line.

WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.

After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.

TESTING THE GAS SUPPLY SYSTEM

When test pressures exceed 1/2 psig (3.45 kPa), the cheesemelter and its individual shutoff valve must be disconnected from the gas supply piping system.

When testing pressures are 1/2 psig (3.45 kPa) or less, the cheesemelter must be isolated from the gas supply system by closing its individual manual shutoff valve.
