Installation Guide III. Installation Requirements Only qualified and/or authorized persons must carry out the installation, gas conversion, and servicing/repair of this equipment. Components having adjustments protected by the manufacturer are not to be adjusted by the installation person. They must only be adjusted by an authorized Service Engineer. This equipment must be installed in an area with sufficient ventilation to prevent the occurrence of unacceptable concentrations of substances harmful to health. - Page 7 Do not put the equipment in an area where the equipment’s flue may be obstructed. Also, do not directly connect the equipment’s flue to any ventilation equipment or system. Any gas burning appliance requires adequate clearance and ventilation for optimum and trouble- free operation.
- Page 8 Install the Flue Remove the Flue from the packaging, then remove all protective film from the flue. Install the flue at the back of the unit by pushing it down. Flue Install the cast radiants (for units with cast radiants) Remove the cast radiants from the packaging.
- Page 9 Install the Lava Rock Kit (for units with Lava Rock Kit) Remove the lava rocks and support racks from the packaging. Then, position the support racks over the burner tubes. The support racks should rest firmly on the front and back support flange. See image below. Support Rack Place the lava rocks over the support rack as shown in the photo below.

Page 13: Operation Guide
Operation Guide This equipment is only for professional use and that it shall be used by qualified persons. Parts or components that have adjustments which are protected by the manufacturer or his agents shall not be adjusted by the user/ operator. Equipment Controls OFF Position Flame Viewing Hole... - Page 14 Lighting the Pilot Burners The burners of this Gas Char-Grill are fitted with individual standing pilots which allows the main burners to be turned ON or OFF without the need to manually re-light the burner each time that it is turned OFF, as the burner will automatically light itself by the pilot burner. Flame Failure Protection is incorporated for each burner by way of a thermo-electric system which will shut off the gas supply to that burner in the event that the pilot burner flame goes out, so that un-burnt gas is not expelled to the surrounding area.
- Page 15 Main burner air supply: For efficient burner operation, a proper balance of gas volume and primary air supply must be maintained which will result in complete combustion. Insufficient air supply results in a yellow streaming flame. The primary air supply is controlled by an air shutter on the front of the burner. Loosen the lock screw on the front of the burner and adjust the air shutter to just eliminate the yellow tips of the burner flame.
- Page 16 Start-up operation or operation from cold start Turn the burners on about 5 minutes before cooking for preheating. Set the knobs to the desired temperature setting or temperature. Each valve will control the gas flow to the burner to bring that area of the unit up to the set temperature. If different temperature settings are to be used, adjoining areas should be set at progressively higher temperatures using the lowest temperatures on the outside burners.

Page 23: Vii. Troubleshooting Guide
VII. Troubleshooting Guide GENERAL INFORMATION ON TROUBLESHOOTING: Burning speed: The velocity at which flame travels through an air-gas mixture. Burning speeds vary with types of gases, and the amount of air mixed with the gas. This air to gas ratio is very important in that it is directly related to flame stability. - Page 24 Burner problems LIFTING FLAMES: How to recognize: When lifting flames occur, part of the flame lifts from the burner port. Lifting flames rise from the ports to burn some distance above the port. In some cases, these flames will drop back to the port and lift again intermittently.
- Page 25 How to correct: Yellow tipping is caused by a lack of enough primary air. This condition may be due simply to an incorrect air shutter adjustment. If this is the case, open air shutters to get rid of the yellow tips.
- Page 26 established. When the appliance heats up it should operate in a normal manner. GAS ODOR AT PRIMARY AIR OPENINGS: Under normal burner operation, a negative pressure (vacuum) should exist inside the primary air openings of a burner, drawing in air. If all gas fed to the burner by the orifice does not flow to the burner head, some gas may spill from the primary air openings.
