Page 15: The Appliance's Heating Cycle
The appliance’s heating cycle The gas required for combustion flows into the manifold via the gas control l. Orifices are located within the manifold. Via these orifices, the gas enters the bar burners C. The bar burners together form the burner tray. As the gas is injected into the bar burners, the primary air required for combustion is also drawn in . -
Page 16: Water Temperature Protection
Functioning of the appliance 2.4.1 Water temperature protection By means of the frost, high-limit and safety thermostats, the burner control monitors three temperatures related to safety. See Table 2.1.
