INFRAREDCHEESEMELTER

OPERATION

VENTILATION

WARNING

Improper ventilation can result in personal injury or death. Ventilation, which fails to properly remove flue products, can cause headaches, drowsiness, nausea, or could result in death.

The flue vent, located at the top of the unit, must not be blocked or covered at any time.

All gas appliances must be installed in such a manner that the flow of combustion and ventilation air is not obstructed. Provisions for adequate air supply must be provided.

NOTICE

Proper ventilation is the owner’s responsibility. Any problem due to improper ventilation will not be covered by the warranty.

Do not obstruct the front of the Cheese Melter since combustion air enters through this area. Be sure to inspect and clean the ventilation system according to the ventilation equipment manufacturer’s instructions.

If a ventilation canopy is used, it is recommended that the canopy extend 6" past the Cheese Melter and that the bottom edge be located 6'6" from the floor. Filters should be installed at an angle of 45° or more from the horizontal. This position prevents dripping grease and facilitates collecting the run-offgrease in a drip pan under the filter.

A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance or may extinguish pilot flames. Fresh air openings approximately equal to the fan area will relieve such a vacuum. The exhaust fan should be installed at least 2" above the vent opening on the top of the Cheese Melter.

If the Cheese Melter is connected directly to an outside flue, a CSA design-certifieddown draft diverter must be installed.

In case of unsatisfactory performance by any gas appliance, check the appliance with the exhaust fan turned OFF. Do this only long enough to check whether doing so corrects any problems with equipment performance. Then turn the exhaust fan back on and let it run to remove any exhaust that may have accumulated during the test.

GASSUPPLY

The Cheese Melter is design-certifiedfor operation on natural or propane gases. The Cheese Melter is shipped configured and adjusted for the type of gas specified by the purchaser, which is indicated on the serial plate (see Figure 1 on page 4). Connect the Cheese Melter ONLY to the type of gas for which it is configured and adjusted.

A model that mounts on the flue riser of a range will have a 3/8" rear gas connection (with a 3/8" male NPT connector) extending through the rear of the flue riser (see Figure 2 on page 6).

Wall-mountand countertop models will have a 3/8” rear gas connection (with a 3/8” male NPT connector). The gas connection can extend directly out the rear of the Cheese Melter (near the bottomright-rearcorner).

Minimum supply pressure is 7" W.C. for natural gas, 11" W.C. for propane. An internal pressure regulator and shutoff valve are provided. If using a flexible-hosegas connection, the I.D. of the hose must not be smaller than the connector on the Cheese Melter, and must comply with ANSI Z21.69. Provide an adequate means of restraint to prevent undue strain on the gas connection. Test pressure should not exceed 14" W.C.

If applicable, the vent line from the gas appliance pressure regulator must be installed to the outdoors in accordance with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or thePropane Installation Code CAN/CGA-B149.2, as applicable.

An adequate gas supply is imperative. Undersized or low-pressurelines will restrict the volume of gas required for satisfactory performance. Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems and affectburner-operatingcharacteristics. A 1/8" pressure tap is located on the manifold to measure the manifold pressure. The supply line to the Cheese Melter should be no smaller than the inside diameter of the pipe on the Cheese Melter to which it is connected.

INFRAREDCHEESEMELTER

OPERATION

DANGER

EXPLOSION HAZARD

In the event a gas odor is detected, shut down equipment at the main shutoff valve. Immediately call the emergency phone number of your gas supplier.

CAUTION

If the Cheese Melter pilots should go out the flow of gas to the Cheese Melter burners is NOT interrupted. Consequently, it is the responsibility of the operator to check the ignition of the burners immediately EVERY TIME the Cheese Melter is turned on. Should ignition fail after 10 seconds, turn off burners, wait 5 minutes, and then try again.

NOTICE

Blodgett Range infrared Cheese Melters cook food in about half the time of conventional Cheese Melters, so adjust cooking times.

Blodgett Range infrared Cheese Melters are unique in design. They incorporate our exclusive ceramic tile burners, which generate infrared rays that provide better quality products in about one-halfthe usual broiling time, and with less gas input than ordinary Cheese Melters. Very little energy is wasted in heating secondary surfaces, which is necessary forconventional-typeCheese Melters.

Since the surface of the ceramic tiles becomes red hot in less than one-halfminute, the Cheese Melter is ready to start broiling with a very short preheat time, thereby saving time, labor and energy. These glowing surfaces emit intense infrared rays, which are transmitted directly onto the product, thereby yielding better tasting broiled food in less time.

The Cheese Melter design supplies 100% clean primary air to the burners, ensuring efficient combustion and maintaining full production capacity and maximum recovery, even in the most severe conditions of grease vapors and smoke atmospheres, which are created during any broiling process.

Blodgett Range infrared Cheese Melters provide such rapid speed and recovery that broiling techniques may require some modification in order to take full advantage of their productive capabilities.

The location of the Cheese Melter controls and other components are shown in Figure 3 below.

INFRAREDCHEESEMELTER

OPERATION

LIGHTINGAFTERGASHASBEENSHUTOFF

When turning on the main gas supply to an appliance or a group of appliances, do the following:

1.Make sure that all the control valves and power switches of all the appliances are in the OFF position.

2.Turn on the main gas supply valve.

3.Light the standing pilots of each connected appliance.

OPERATION OFINFRAREDCHEESEMELTER

Blodgett Range infrared Cheese Melters finish product in half the time of ordinary Cheese Melters. The burners reach operating temperature in just 90 seconds, and their intense infrared energy quickly heats the food, not the surrounding air. The rack adjusts to five heights on rack guides.

The cooking area has removable racks and drip trays for cleaning. As food cooks, drippings drain into a collection tray on the bottom of the Cheese Melter cavity. To operate the Cheese Melter, do the following:

1.Light the constant-burningpilots located near the front of the Cheese Melter burners (unless the pilots are already lit).

2.If necessary, pull out and empty the bottom grease drawer.

3.Turn the burner control to HIGH and visually check that the burners have ignited. When the burners ignite, a blue haze-typeflame will cover the surface of the ceramics, but will gradually disappear within two minutes. When the burner control is set to HIGH, the ceramics will glow red and the flame on the surface of the ceramics should be barely visible, with little or no blue haze. When the burner control is set to LOW, the surface of the ceramics will glow very dull red and the flame will have ablue-hazecolor. (If the flame flutters or “pops, increase the temperature setting.)

4.Turn the burner control to HIGH or LOW (as appropriate for the food to be finished).

5.Raise or lower the Cheese Melter rack to the height appropriate for the food to be finished.

6.Finish the food for the desired appearance. Periodically check the Cheese Melter grease drawer and empty it when necessary.

7.When done broiling, turn the burner control to OFF

LIGHTINGCHEESEMELTERPILOTS

The pilots should burn continuously unless the Cheese Melter is to be completely shut down. The Cheese Melter cavity has two or three pilots, each near the front of a pair of burners. If the pilots are extinguished, the pilot gas supply is NOT automatically interrupted. To light the pilots, do the following:

1.Turn the control valves on the front of the Cheese Melter to OFF.

2.Turn on the gas supply to the Cheese Melter (if not already on).

3.Light the pilots.

SHUTDOWN OFCHEESEMELTER

To place the Cheese Melter in a standby state (ready for use), turn the burner control valves to OFF. The pilots will remain lit.

To completely shut down the Cheese Melter for an extended period (or prior to disconnecting the gas supply), turn OFF the manual shutoff valves of all gas supply connections. (This will extinguish all pilots.)

CLEANING& MAINTENANCE

INFRAREDCHEESEMELTER

CLEANING& MAINTENANCE

WARNING

Shut off the gas supply to the appliance before cleaning or performing maintenance on any gas appliance.

The appliance may be equipped with a restraint device to limit its movement in order to prevent damage to the gas connection. If disconnection of this restraint is necessary to move the appliance for cleaning or maintenance, reconnect the restraint when the appliance is moved back to its original installed position.

Blodgett Range equipment is sturdily constructed of the best materials and is designed to provide durable service when treated with ordinary care. To provide the best performance, your equipment must be maintained in good condition and cleaned daily. Naturally, the periods for this care and cleaning depend on the amount and degree of usage.

Following daily and periodic maintenance procedures will enhance long life for your equipment. Climatic conditions (such as salt air) may require more thorough and frequent cleaning or the life of the equipment could be adversely affected.

Keep exposed, cleanable areas of Cheese Melter clean at all times. (See next page for instructions on cleaning stainless steel and baked-enamelsurfaces.)

DAILYCLEANING ANDMAINTENANCE

To prevent excess smoking, the Cheese Melter grid, bottom grease drawer, and the other Cheese Melter components must be kept clean of food remnants. Use a wire brush or similar scraping utensil. DO NOT use steel wool or a similar scrub pad that will leave small particles, which can get into food. The daily cleaning procedure is as follows:

1.Remove the Cheese Melter grids and clean them with a wire brush or non-toxicsolvent.

2.Remove the bottom grease drawer and clean it.

3.Check that nothing has been placed on top of the Cheese Melter (which will block the escape of combustion exhaust).

4.Check that the air-intakeopenings on the rear of the Cheese Melter are not obstructed.

MONTHLYCLEANING ANDMAINTENANCE

The following tasks should be performed monthly:

1.Check for proper pilot operation. The flame on each pilot should be just large enough to extend along the flame carrier to the burner surface. If adjustment is necessary, call for service.

2.Check for proper burner operation. When the burner control is set to HIGH, the ceramics should glow red and the flame on the surface of the ceramics should be barely visible, with little or no blue haze. When the burner control is set to LOW, the surface of the ceramics should glow very dull red and the flame should have a blue-hazecolor. If flame should flutter or “pop”, adjust to higher temperature setting.

SEMIANNUALCLEANING ANDMAINTENANCE

At least twice a year the venting system should be examined and cleaned.

STAINLESS-STEELSURFACES

To remove normal dirt, grease and product residue from stainless steel surfaces that operate at LOW temperature, use ordinary soap and water (with or without detergent) applied with a sponge or cloth. Dry thoroughly with a clean cloth.

To remove BAKED-ONgrease and food splatter, or condensed vapors; apply cleanser to a damp cloth or sponge and rub cleanser on the metal in the direction of the polishing lines on the metal. Rubbing cleanser, as gently as possible, in the direction of the polished lines will not mar the finish of the stainless steel. NEVER RUB WITH A CIRCULAR MOTION. Soil and burnt deposits, which do not respond to the above procedure, can usually be removed by rubbing the surface withSCOTCH-BRITEscouring pads or STAINLESS scouring pads. DO NOT USE ORDINARY STEEL
