    Operation Operation Guide CAUTION: • THIS APPLIANCE IS FOR PROFESSIONAL USE AND IS ONLY TO BE USED BY QUALIFIED PEOPLE. • ONLY QUALIFIED SERVICE PERSONS ARE TO CARRY OUT INSTALLATION, SERVICING OR GAS CONVERSION OPERATIONS. • COMPONENTS HAVING ADJUSTMENTS PROTECTED (E.G. PAINT SEALED) BY THE MANUFACTURER SHOULD NOT BE ADJUSTED BY THE USER/OPERATOR.
  • Page 10 Operation WARNING: SURFACE TEMPERATURE OF THE CHAR-BROILER CAN REACH OVER 300°C WHEN THE APPLIANCE IS OPERATED AT FULL SETTING. 1. Lighting the Main Burners The burners are fitted with individual standing pilots which allows the main burners to be turned ON- OFF without the need to manually re-light the burner each time that it is turned ON, as the burner will be automatically lit itself by the pilot burner.
  • Page 11 Operation Main burner air supply: 1. 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. Primary air supply is controlled by an air shutter on the front of the burner. 2.
  • Page 12 Operation OPERATION: Turn the burners on about 15-20 minutes before cooking for preheating. Set the knobs to the desired flame height 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 13: Cleaning And Maintenance

    Trouble shooting This section provides an easy reference guide to the more common problems that may occur during the operation of your equipment. The fault finding guide in this section is intended to help you correct, or at least accurately diagnose problems with your equipment.
  • Page 16 Trouble shooting GENERAL INFORMATION 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 17 Trouble shooting BURNER PROBLEMS LIFTING BURNER FLAMES: Excessive primary air can cause flames to lift and blow off the burner ports which can be noisy as well as inefficient. More importantly however is the production of dangerous carbon monoxide under this condition.
  • Page 18 Trouble shooting BURNER PROBLEMS– cont’d. FLOATING FLAMES: The difference between floating flames and lifting (or blowing) flames should be clearly understood. Both conditions are undesirable, but the causes and corrective steps are different. Floating flames are lazy looking. They do not have well defined cones, and appear to be “reaching” for the air. They are long, ill- defined, quite flames which roll around in the combustion chamber sometimes completely off the ports.
