Page 14: Theory Of Operation
Gas Cooktop (CTG) Series Gas Cooktop (CTG) Series Theory of Operation OPERATION INFORMATION A service technician should understand how a gas appliance operates before attempting to service the appliance. This section provides descriptions of the different types of fuel gases and explains gas heating values. A definition of specific gravity of gas is given along with its characteristics and effects. - Page 15 Gas Cooktop (CTG) Series Gas Cooktop (CTG) Series Theory of Operation PRINCIPLES OF GAS COMBUSTION: Combustion - When oxygen acts with a substance to produce large amounts of heat rapidly. Requirements for Combustion - There are three required elements for combustion to occur; Fuel (Gas), Oxygen (Air) and Heat (Ignition Temperature, which for gas is between 1100°F/593°C and 1200°F/649°C).
- Page 16 Gas Cooktop (CTG) Series Gas Cooktop (CTG) Series Theory of Operation BURNER COMPONENTS for 15”, 30” and 36” Burner Head - The component containing the burner ports where the gas/air mixture ignites. The burner ports are distributed in a useful pattern to optimize heat transfer. The flames should be spread so they can be easily reached by secondary air and provide a stable blue flame.
- Page 17 A distinguishing feature of Wolf’s low Btu/hr control is its constant, low heat output without continuous ignitions. Flame diameter remains full size, only the heat output is lowered. This is the ultimate control for simmering food.
