HOW YOUR WATER HEATER WORKS
Water is stored in a vitreous enamel lined steel cylinder and heated by a gas burner located under the cylinder. The heat produced by the burner is transferred to the water through the base of the cylinder and through the wall of a flue pipe which passes through the centre of the cylinder. A flue baffle in this flue ensures the efficiency of the water heater is correct. The gas supply to the burner is controlled by the thermostat so the water is heated to a constant temperature. Automatic safety controls are fitted to the water heater to provide safe and efficient operation.
MAINS PRESSURE
The water heater is designed to operate at mains pressure by connecting directly to the mains water supply. If the mains supply pressure in your area exceeds that shown on page 14, a pressure limiting valve must be fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
PIEZO IGNITION
The “Piezo” push button igniter makes lighting the pilot flame of your water heater very easy. Simply follow the instructions on the label attached to the front of the water heater. There is no need for matches to light the water heater.
PILOT IGNITER
A permanent pilot flame burns to ignite the main burner automatically. Heat from the pilot is absorbed by the water.
GOING ON HOLIDAYS
If you are going on holiday for more than a few days the thermostat can be set to the “·” (pilot) position to conserve energy (refer to point 1 of “Close Down Procedure” on page 27). If it is necessary to turn off the water heater, refer to “To Turn Off The Water Heater” on page 5.
