I. INITIAL STEPS

1. Placing the Machine

Barbecue products are often bought on impulse. The continuous style rotisserie models have been designed for maximum viewing by both the customers as well as the operator. The unit usually has a front glass surface and should be placed where it will get the best and most exposure. Wherever the unit is placed, remember that the operator will need continual access through the glass doors.

WARNING: THESE MACHINES ARE OVENS AND SHOULD NEVER BE PLACED

WITHIN PUBLIC ACCESS. FOLLOW MINIMUM CLEARANCE REQUIREMENTS FOR ALL UNITS AS PER SPECIFICATION GUIDES.

2. Assembling the Machine

The N/45G come fully assembled except for the glass, spits, skewers, baskets and thumb screws, which are individually packed. Check all parts and accessories with your packing list. Remove all tape on glass and vinyl coating on stainless steel before operating the machine.

3. Electrical Connection

The electrical connections on the N/45G is less than 15 amps, 120V, so just connect the plug supplied with the unit into a regular outlet.

4. Gas Connection

The N/45G gas connection must be performed by a licensed gas fitter. All units are supplied with a main shut off valve (gas cock) and a pressure regulator.

5. Venting

The N/45G is fully opened along the top for air evacuation and must be placed under a canopy type hood.

II Installation Instructions

1.1 General Information

The Operating Instructions are to be given to the operator of the rotisserie. All unit operators are to be familiar with the functions of the rotisserie.

The Operating Instructions should be kept in a location close to the rotisserie. It should be easily recognizeable and easily accessible.

These rotisseries can be used with both natural and LPG gases. The rotisseries can be converted or adjusted to any type of the locally distributed natural and LPG gases.

It is recommended that a repair and maintenance contract be signed with the manufacturer's agent, distributor, or service agency .

1.4 Conversion and Adjustment Instructions

Before converting or adjusting the machine, it is imperative that the manual gas cock be turned to the "off" position. The electrical power to the machines should also be turned off. When converting from one type of gas to another, the main gas orifice (or injector), the pilot burner orifice (or injector), and the primary air adjustment must be changed according to the table on page 9. In addition, the spring in the pressure regulator must be changed so that it can operate at higher pressures.

1.6 Verification for use with Natural Gas

The highest flame setting ("on" position on the manifold gas valves) for each of the pipe burners can be confirmed by using the volumetric method in conjunction with the main gas meter. From the "pilot" position, turn the Gas Control Lever clock-wise, towards "on", until the lever goes no further.

T o carry out this verification procedure, it is necessary to obtain the heating value (BTU/ft3) of the local gas from the local gas company .

If the measured gas volume does not correspond to the values in the following table, the first item which should be checked is the incoming (connected) gas pressure. If the pressure is correct, it must be verified that the proper size gas orifices are in place.

E = Flow rate in ft3/minute

FP = High Flame Power setting in BTU/hr

Hi= Heating value in BTU/ft

Thus, for natural gas:

E = 60,000 BTU/hr = 57.75 ft3/hr = 0.96 ft3/min. 1040 BTU/ft

E = 0.96 ft3/min.

Calculation of the natural gas needed in 1 hour by a 45WDG (3 burners) at full power:

57.75 * 3 = 173.25 ft3/hr = 2.89 ft3/min.

The time and the flow measurements should be taken at the gas (flow) meter with a chronometer (stop watch).

T o run the test, open the manual gas cock valve, start up the unit according to the start-up instructions on page 24 and set the manifold valves to the high flame setting ("on" position).

Allow the unit to pre-heat (burn) for 10 to 15 minutes. Verify that the flow rate is calibrated to the appropriate flow rate indicated in the table.

1.9 Changing Gas Orifices

1.9.1 Changing the Main Gas Orifice

1. The venturi tubes and manifold valves are on the same side as the spit handles.

2. On each venturi, loosen the lock nuts (7/8" wrench) and then move the nut and the air intake cap all the way to the top of the nipple.

3. With a 3/4" wrench, loosen the nipple so that it can be removed from the venturi.

4. With the nipple/orifice assembly off, separate the main orifice from the nipple with a pipe wrench or a pair of pliers.

1.9.2 Changing the Pilot Orifice

1. T o reach the pilot burner , open the sliding glass doors, the sliding or hinged metal door, remove all spits, as well as all ceramics.

2. Before removing, mark the position of the support bracket on the side wall.

3. Loosen the pilot burner assembly by removing the two screws which attach each pilot burner (support bracket) to the main body of the machine.

4. With the assembly loose, carefully pull the entire assembly forward about 6".

5. Loosen the gas line connection to the pilot orifice with a 7/16" wrench. Carefully separate the gas line from the pilot burner . From the pilot burner, carefully remove the pilot orifice using a 1/2" wrench.

6. Reassemble the pilot burner using the new pilot orifice and place the support bracket in its original position. The following pilot orifices are to be used with each type of gas.

1.10 Checking the Connected Gas Pressure (Nominal Pressure)

Close the gas cock where the gas line is connected to the machine and attach a manometer to the tap (allen screw) on the gas cock. With the manometer connected, open the gas cock, ignite all burners, and set the manifold valves to "on" or maximum setting. Along with

all other gas appliances at the location in operation, measure the gas pressure.

This nominal pressure should be 5.5" W.C. for natural gas and 11" W.C. for LPG.

If the measured pressure falls below the range mentioned above, the installer should try to find the cause of the problem and resolve it. A typical source of this problem is that the gas line (pipe) diameter leading up to the unit is too small. If it is not possible to resolve the problem, the local gas company or gas supplier should be contacted so that they can resolve the problem.

If the nominal pressure is below 5.5 " W.C. for natural gas or below 11 " W .C. for LPG, the unit should not be operated. These should be adjusted to the ideal settings using the pressure regulating screw on the pressure regulator.

Hickory Industries, Inc.

If the pressure is too high and can not be adjusted downward, check to see if the proper adjusting spring is in place. If this is correct, the regulator membrane may have been ruptured by excessive gas pressure and may have to be replaced. Do not operate the rotisserie if the gas pressure is too low .

If the pressure is too low and can not be adjusted upward, also check the regulator. If this is correct, verify the pressure coming out of the main gas meter or the diameter of the gas pipe feeding gas to the unit. If the gas line is under-sized, the appropriate pressure may not be reached. Do not operate the unit if the pressure falls below 5.5" W.C.

After the pressure has been set, close the gas cock once again, remove the manometer, seal the pressure regulator, and then re-open the gas cock.

WARNING: After an installation, repairs, or maintenance, make sure that there are

no gas leaks anywhere in the gas lines or system.

1.11 Maintenance, response to technical problems, reasons for problems and solutions

Should a technical problem arise for any reason, shut off the machine and call for technical service.
