VCM72 / CMJ72 2 48,000 (2 @ 24,000)

INSTALLATION

Before installing, verify that the type of gas (natural or propane) and the clearance
dimensions (see page 4) agree with the specifications on the rating plate which is located
under the crumb tray on the right side. If the supply and equipment requirements do not
agree, do not proceed with the installation. Contact your dealer immediately. It is
recommended that a trained gas service technician with the necessary tools, instruments
and skills perform the installation of the cheesemelter

UNPACKING

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.

Before using, remove all packaging material and protective plastic from the surfaces of
the unit. Carefully unpack your cheesemelter and make sure that no parts are discarded
with the packaging material. A pressure regulator designed to operate with the
cheesemelter has been supplied and must be installed before the cheesemelter is placed
into service. (Refer to GAS PRESSURE REGULATOR INSTALLATION in this manual).

LOCATION

The equipment area must be kept free and clear of combustible substances.

Minimum Clearances
Combustible Construction Non-Combustible Construction
Back 2" 0"
Sides 20" 0
Bottom 10" 4"

The installation location must allow adequate clearances for servicing and proper
operation. While another gas-fired cheesemelter can be placed adjacent to this
Cheesemelter, there must be no obstruction to the front of the Cheesemelter. A minimum
front clearance of 36" (91 cm) is required.

It is recommended that the cheesemelter not be installed directly over or directly adjacent
to charbroilers, griddles or fryer banks. Infrared burners can be susceptible to the effects
of grease laden smoke and installation in these locations may shorten burner life. The
cheesemelter must be installed so that it is level side to side and front to back.

Do not obstruct the flow of combustion and ventilation air. 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 replace air taken out by the ventilating system.

Do not permit fans to blow directly at the Cheesemelter. Avoid wall-type fans which
create air cross currents within the room. Avoid open windows next to the Cheesemelter.
Maintain an 18" (46 cm) clearance from the top of the flue vent to the filters of the hood
venting system or any other obstruction.

ASSEMBLY

Cheesemelters Mounted on a Counter

Cheesemelters mounted on a counter must be equipped
with 4" (10 cm) legs(sold separately). Screw the legs
into the threaded attachment points on the bottom of the
unit. The countertop must be of noncombustible
construction. Place Cheesemelter in position, then level
by adjusting the bullet feet.

Cheesemelters Mounted on a Wall

1. Make sure brackets are level and properly spaced
so that bracket holes will align with the threaded
attachment points on the bottom of the unit.

2. Mount the brackets only in the upside-down “L”
position as shown. 24 thru 48 models require two
brackets while 60 and 72 models require three
brackets for proper support.

3. Secure brackets to wall by means of lag screws or
bolts. Make sure the lag bolts or screws engage
wall studs.

4. Place unit into position on the brackets, making sure
that the unit’s bottom threaded attachment points
are aligned with the holes in the brackets.

5. Secure unit into position with four (24 to 48 models)
or six (60 and 72 models) 3/8” bolts. Thread the bolts
through the holes in the brackets and into the threaded
attachment points on the bottom of the unit.

Cheesemelter Mounted on Special Hi-Shelf

If the Cheesemelter is to be mounted over a Gas Range,
a reinforced hi-shelf designed for that range is required.

1. Place and align Cheesemelter on top of shelf brackets;
place the back of the unit flush with the rear of the shelf.

2. Align holes in the shelf with the threaded attachment
points on the bottom of the cheesemelter.

3. Secure cheesemelter into place with four 3/8” bolts .
Thread the bolts through the shelf and into the threaded
attachment points at each corner of the cheesemelter.

GAS CONNECTIONS

Gas supply connections and any pipe joint compound must be resistant to the

action of propane gases.

Location of the gas inlet is at the top right rear corner of the top panel. Codes require that
a gas shutoff valve must be installed in the gas line ahead of the Cheesemelter.

Use a ¾” NPT gas supply line for the cheesemelter inlet. All flexible and semi-rigid gas
supply lines must comply with the applicable ANSI standard. To ensure maximum
operating efficiency this appliance must be connected with a gas supply line of solid pipe
or a commercial type Flexible Connector with the net inside diameter (I.D.) as large as or
larger than the gas pipe inlet on this appliance.

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 checking for leaks all lines receiving gas should be fully purged to remove air.

Maximum line pressure for natural and propane gas is 14" W.C. Minimum line pressure is
7" W.C. for natural gas and 11" W.C. for propane gas.

TESTING THE GAS SUPPLY SYSTEM

When gas supply pressure exceeds ½ psig (3.45 kPa), the Cheesemelter and its
individual shutoff valve must be disconnected from the gas supply piping system.

When gas supply pressure is ½ psig (3.45 kPa) or less, the Cheesemelter should be
isolated from the gas supply system by closing its individual manual shutoff valve.

FLUE CONNECTIONS

Do not obstruct flow of flue gases from the flue located on the rear 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.

Information on the construction and installation of ventilating hoods may be obtained from
the standard for "Vapor Removal from Cooking Equipment," NFPA No. 96 (latest edition),
available from The National Fire Protection Association, Batterymarch Park, Quincy, MA

02269.

GAS PRESSURE REGULATOR INSTALLATION

Gas regulator pressure is preset at 5” Water Column (W.C.) for natural gas, and 10” W.C.
for propane gas. Minor adjustments may be required based on site specific gas pressure.

Install the regulator as close to the cheesemelter on the gas supply line as possible.
Make sure that the arrow on the underside of the regulator is oriented in the direction of
gas flow to the cheesemelter (Fig. 2) and the regulator is positioned with the vent plug
and adjustment screw upright (Fig. 3).

Fig. 2

The minimum supply pressure (upstream of the regulator) should be 7-9” W.C. for natural
gas and 11-12” W.C. for propane gas. At no time should the cheesemelter be connected
to supply pressure greater than ½ psig (3.45 kPa) or 14” W.C.

Gas supply connections and any pipe joint compound must be resistant to the

action of propane gases.

Prior to lighting, check all joints in the gas supply line for leaks.

Use soap and water solution. Do not use an open flame.

PREHEATING

Place the rack in its highest position. Turn the burner valve knob completely
counterclockwise and preheat for 15 minutes.

RECIPE AND RACK ADJUSTMENT

Positioning the Cheesemelter rack is an important factor in the desired product end
results. Position the rack farther away from the burners for thick casseroles and for
melting cheese or butter to avoid drying the product. Position the rack closer to the
burners for bacon, toast and quick heating, but watch carefully to avoid burning.

CLEANING

The cheesemelter and its parts are hot. Use care when operating,

cleaning or servicing the cheesemelter

Interior

When the Cheesemelter is cool, remove rack. Clean the rack and crumb tray daily by
soaking in warm detergent water. Scrub with a stiff-bristled brush. Do not use harsh
abrasives.

After scrubbing, wash with soapy water, rinse and dry. Soap and water will normally do
the job. Heavy spattering or spillovers may require cleaning with mild cleaner or soapy
wet pads.

Exterior

When the Cheesemelter is cool, knobs and stainless steel surfaces may be cleaned with
mild soap and water applied with a damp cloth. Wipe the surface with clean water and
dry with a soft clean cloth. Do not use abrasive cleaners or strong liquid cleaners on
stainless steel surfaces as they may damage the finish.

Spray-On Cleaners

Be careful when using spray-on cleaners. Some cleaners may contain caustics. Please
follow cleaner manufacturer's instructions.
