2. THESE UNITS SHOULD NOT BE PLACED IN CABINETS OR ENCLOSED AT THE TOP. THE BURNER ASSEMBLY HAS AIR INTAKES AT THE ENDS AND THE FRONT LEADING EDGE. THESE AREAS MUST BE KEPT FREE FROM OBSTRUCTION.
3. IF STACKED – DO NOT ATTACH OR ENCLOSE.
4. CARE SHOLD BE TAKEN TO ROUTE WIRING AWAY FROM FLUE AREA.

INITIAL START UP

NOTICE
During the first few hours of operation you may notice a small amount of smoke coming from the unit, and a faint odor from the smoke. This is normal for a new unit and will disappear after the first few hours of use.

PRE-POWER ON
After the Melter is connected to power and gas, prior to turning on, verify the following:

• The manual gas valve opens and closed freely.
• The rack moves up and down freely
• All packing material has been removed from the Melter.
• The Melter has no gas leaks.

POWER ON & PILOT LIGHTING
Lighting Instructions:
The pilot burner must be lit with a match. Gas flows to the pilot as soon as all the gas valves are turned On. Be aware that it may take a few minutes, on new installations, for  gas to be present at the pilot burner, as air must first be purged from the gas line.
The pilot burner will remain lit even if the Cheese Melter is switched to Off.
Once the pilot burner is lit, allow one minute for pilot to heat enough to enable the main burner to light.
Set the Constant – Auto switch to Constant and allow the machine to run for five minutes. A small amount of smoke may emanate from the machine as it heats, do not be  alarmed as this is a normal condition related to the burning off of oils associated with the manufacturing process. Set the Constant – Auto switch to Auto to place the machine into the Stand-by mode.
Note: Electrical power is required to safely operate this cheese Melter. This unit will not operate in the event of a power failure, but pilot gas will continue.
TO SHUTDOWN UNIT
Turn off electrical supply to the unit and shut off the gas supply manual valve located in the gas supply line at the bottom of the unit at the rear gas entry.

OPERATION

CAUTION
ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE FROM COMBUSTIBLE MATERIALS.
CAUTION
KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND DRY. IFSPILLS OCCUR, CLEAN IMMEDIATELY, TO AVOID THE DANGER OF SLIPS OR FALLS.

GENERAL
The Lang gas Melter can be used to poach, sauté and brown. In addition to melting cheese on sandwiches, French onion soup, hot apple pie and casseroles, it may be used for finishing Italian, Mexican and au gratin dishes utilizing less energy than conventional broilers. The product is heated with 1650°F of infrared heat, which penetrates the product preventing burning and scorching. The rack is counterbalanced so that maximum heat is  supplied only when the product is placed in the rack.
Although the heating elements are not directly controlled to regulate heat, the exposure of the product to heat is adjustable. Heat adjustment may be obtained by raising and  lowering the rack position. The shelf positions provide a choice of cooking positions for a variety of applications. The top position is very hot, and can be used for quick  browning and toasting, with the heat decreasing at each lower position.
In order to change positions, simply slide the rack in and out of the slots provided. Make sure that the end of the rack engages the sliding mechanism located on the right front corner.

CONTROLS
There are very few controls that operate the gas cheese Melter. Below is a list of the various components with a description of their purpose.
Power Switch Turns the unit On and Off.

Constant /Auto Switch
When set to Constant, the burner(s) will light and stay on. When set to AUTO, the burner(s) will light whenever a product is placed onto the Tilting Product Rack.
Manual Gas Valve
This valve turns off the flow of gas to the burner(s). Once the machine is installed, this valve need not be turned off as the POWER SWITCH should be utilized to shut the  machine down. The manual gas valve cannot be used to regulate the heat output from the burner(s), it must be full ON or full OFF.
Tilting Product Rack
The Tilting Product  Rack is used to adjust the amount of heat a product is exposed to and to start the burner(s) when the machine is placed into the Auto mode. Raising the tilting  product rack increases the heat on the product while lower the rack decreases the heat.

OPERATING DO’S AND DON’TS
DO:
Insure all dishes placed in the Melter are oven safe.
Pre-heat pans in the Melter or on a stove.
Turn products halfway through cooking, as needed.
Use the unit in Automatic as much as possible, use Constant during peak periods.
DON’TS
Do not use the Melter as a cooking or baking device; it is best suited for finishing dishes immediately prior to serving.
Do not use the unit to heat or thaw chilled or frozen product.
Do not place aluminum foil on the rack or bottom shelf. This will reflect heat and expose components to unnecessary high temperatures.
Do not move rack from one position to another without hand protection.

MAINTENANCE & CLEANING

WARNING
KEEP WATER AND SOLUTIONS OUT OF CONTROLS. NEVER SPRAY OR HOSE CONTROL CONSOLE, ELECTRICAL CONNECTIONS, ETC.
CAUTION
MOST CLEANERS ARE HARMFUL TO THE SKIN, EYES, MUCOUS MEMBRANES AND CLOTHING. PRECAUTIONS SHOULD BE TAKEN TO WEAR  RUBBER GLOVES, GOGGLES OR FACE SHIELD AND PROTECTIVE CLOTHING. CAREFULLY READ THE WARNING AND FOLLOW THE  DIRECTIONS ON THE LABEL OF THE CLEANER TO BE USED.

CLEANING
The unit should be thoroughly cleaned once a day to insure against accumulation of foreign material.

• Always start with the unit cold & disconnect from its electrical source.
• The stainless exterior can easily be cleaned using stainless steel cleaner
• Always follow the cleaner manufacturer’s instructions when using any cleaner.
• Care should be taken to prevent caustic cleaning compounds from coming in contact with the blower wheel.
• The oven racks, rack slides, and interior may be cleaned using oven cleaner.
• Discoloration or heat tint may be removed using a Carbon Release oven cleaner.
• The oven interior should be cleaned using a mild soap and a non-metal scouring pad. DO NOT use caustic cleaners.

Always apply these cleaners when the oven is cold and rub in the direction of the metal’s grain.
MAIN BURNER ACCESS
The main burner is removed through the top of the machine.
Remove the stainless steel top-front first by removing six sheet metal screws from the ends.
Remove the entire top assembly by removing several sheet metal screws along the edge of the top.
Remove the gas line from the burner at the compression fitting on the orifice.
Remove the two nuts at the opposite end of the burner from the orifice.
Lift the main burner from the machine.
MAIN BURNER ORIFICE ACCESS
The main burner orifice can be access without taking the burner from the machine.
Remove the stainless steel top-front first by removing six sheet metal screws from the ends.
Remove the entire top assembly by removing several sheet metal screws along the edge of the top.
Remove the gas line from the burner at the compression fitting at the orifice.
Unscrew the orifice fitting from the burner.

PILOT BURNER ADJUSTMENT
Pilot flame adjustment is accomplished at the brass tube fitting on the main manifold.
The brass fitting located between the regulator and the solenoid valve which has the 1/8 inch tube connected to it is the adjuster.
Turn the hex head screw clockwise to shorten the pilot flame, and counterclockwise to lengthen the pilot flame.

• The pilot must light the main burner within 5 seconds of gas being available at the burner tiles (listen for the solenoid valve to open).
• The pilot must light the main burner without snuffing itself out.
• The pilot must continue to burn during an extended continues operation of the main burner.

RACK SWITCH ADJUSTMENT
The rack switch is located at the extreme right of the control compartment.
The Tilting Product Rack should energize the tilt switch at the mid-point in its travel.
To adjust the switch, bend the actuator arm.
