Description of the rotisserie

Technical description
Heating takes place by means of gas that is burnt in a heat exchanger placed in the ceiling. A fan mixes the gas and air, and which mixture is ignited by means of an automatic ignition. The combustion takes place in the inner part of the heat exchanger and is therefore not visible. The flue gasses are discharged through a flue tube at the top or side off the rotisserie. Fans ensure an equally divided heat. To maintain the set temperature, the heat exchanger is modulated and repeatedly switched on and off during the grilling process.

During the entire process, the interior of the rotisserie will be illuminated by halogen lamps. The rotisserie control keeps the temperature inside the rotisserie fixed to the level set by the operator. The rotor is being wheeled by a maintenance-free motor and gearbox. The hardened glass panes are equipped with a heat-reflecting layer to keep the heat inside the grill. The plating of the rotisserie is made of stainless steel. The product contact parts are made of stainless steel AISI 304. The mains cable is provided with a plug.
Refer to the data plate for the applicable gas system.

Intended use
The rotisserie has been designed for grilling meat products and has a semi- self-cleaning feature. Any other use will not be regarded as intended use.

Electrical supply
Prior to installation, test the electrical service to assure that it agrees with the specifications on the machine data plate located on the right-side panel near the controls. The connecting cable for the rotisserie is equipped with an approved plug connection. If use is to be made of a permanent connection, the connecting cable must be connected to a manual on/off switch that is installed near the rotisserie in a clear visible manner. In all cases, a strain relief must be installed where the cable enters the rotisserie. The rotisserie must be connected according to the figure below. The electrical diagram is supplied with the documentation package inside the rotisserie. For a 1-phase 208 V ~ circuit with neutral, the rotisserie must be connected according to the figure below.

A ground (earth) connection must be provided and installed in accordance with state and local codes.

Gas connection
All gas supply connections and any pipe joint compound used must be resistant to the action of propane gases. Codes require a gas shutoff valve be installed in the gas line ahead of the rotisserie. The gas inlet is located on the bottom side, under the electric compartment. (marked 4 in drawing below) With a gas conduit (not included) you can lead the gas connection to the main gas supply. Connect the rotisserie to the gas line after leveling. Gas supply line must be at least the equivalent of 1/2“ (12.7 mm) iron pipe and capable of maintaining the required gas pressure during full power. Make sure the pipes are clean and free of obstructions, dirt, and piping compound.
Note : After the piping has been checked for leaks, fully purge gas pipes to remove air. Disconnect the rotisserie from t he gas supply piping system during any pressure testing on the gas supply piping system.
Note: Check all joints in the gas supply line for leaks prior to start up the rotisserie. You can use a soap and water solution. Do not use an open flame.

The gas inlet pressure has to be according to the table on the technical data page. (Chapter 1) The pressure can be checked on the gas block with a pressure meter like in the picture below.

• Gas inlet: Inlet of gas after gas pressure reduction valve (max. 22“ H2O). Pressure depending of gas type.
• Gas outlet: Outlet of gas into gas mixture blower.
• Coils: 2 Coils for the gas valves.
• Inlet pressure: Measuring tube for gas pressure after reduction valve. In order to measure loosen the screw on inside of the tube.

Measuring notes

•  Inlet pressure: During operation you measure the pressure of the setting of the reduction
•  Outlet pressure: During operation you measure a pressure of zero.
• You can use this measuring point also to check if the gas valves are opening. When you start up t he machine and the valve is not opened yet you measure a under pressure due to the suction of the gas mixture blower and this pressure will be zero when the valve is opened.

Flue gas analyzer
With the flue gas analyzer you can measure the exhaust gas on the rotisserie for toxicity. With the use of a Testo 330-1LL you get the following measurements:

Values below are references and factory defaults.

 | RPM [min-1]| CO2 [%]| Power Hs in

[kW]

| Power Hs in [BTU]
---|---|---|---|---
High load| 6350| 9,70 %| 24| 82000
Low load| 2500| 9,20 %| 8,9| 30368
Start load| 4640|  | 17,5| 59030

Gas consumption
With a flow meter you can measure the gas consumption/flow. See table on page 4.
To get an accurate consumption you have to do a measurement of 3-5 minutes. During this period the rotisserie may not be turned off and no other gas device on the same gas line may be active.

•  A descaling filter is advised when the hardness of the water is > 4° dH (4 Grains/Gal).
• A descaling filter is mandatory when the hardness of the water is > 20° dH (20 Grains/Gal).

Note that the cleaning capacity of the cleaning tablets will decrease with harder water.
The by-pass of the descaling filter, if applicable, needs to be adjusted to zero. Refer to the filters manual to determine the filter capacity. This filter capacity needs to be adjusted in the manager parameters.

Connecting the drain tube
An open draining system with a 110 mm (4 1/2”) funnel is recommended. The drain tube has an outside diameter of 33 mm (1 5/16”).

• It is not allowed to make a closed connection, the connection must be aerated!
•  Make sure that the tube is not kinked and is sloping downwards to the drain funnel.
•  The minimum inside diameter of the sewer pipe needs to be 40 mm (1 1/2”).
•  A siphon in the customers sewer is highly recommended to prevent odors from coming out of the sewer.
•  See below examples

Extraction of the rotisserie
The rotisserie must be located under an extraction hood which has adequate connection to an exhaust duct and extends 8” beyond the rotisserie sides. Clearance above the rotisserie flue should be adequate for the products to escape so that there is no interference with the heat circulation in the rotisserie. Refer to ANSI/NFPA 96, ” Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations” (latest edition). The LDR Gas produces about 600 cf water vapor per cycle.

Consider the following guidelines for the extraction hood:

• The minimum capacity of the extraction hood has to be 900 cfm
•  The extraction hood has to extend a minimum by 8” on all sides of the rotisserie
•  The extraction hood has to have a free height, above the rotisserie, of a minimum of 16”
•  The rotisserie has to be accessible for service purposes
•  Flue connections should never be made directly to the rotisserie.

Grease collection
