  • fixtures;
  • casing with temperature and power adjustments as well as an LED display.

The heat exchanger is treated with a special anti-corrosion coating. Heating up is done automatically:

  • the tap is opened;
  • heat exchanger receives the cold heat carrier;
  • the burner is started;
  • heat carrier is heated up and flows out.

Before installing the Zanussi gas appliances, a plan for their location is drawn up. It is coordinated with the gas utility. The Zanussi gas heater is to be connected only by employees of the appropriate service. According to the instructions for the water heaters, the following demands are placed on the premises:

  • volume over 8 m³;
  • good ventilation;

The burner switches off automatically if the no draught, water overheating sensors are triggered. The ignition is powered by finger-size batteries, which must be changed regularly.

A small window is located on the case so that the flame can be observed. Perfect combustion is uniform, with a blue color fire. If yellow tongues or soot appear, the burner is cleaned. To do this, turn off the burner, disassemble it. The burner is cleaned from soot, dust, washed with soap solution. At the same time the electrodes are checked. All elements are dried and assembled.

It triggers in case of poor draft, high water temperature, high gas pressure, water pressure, sudden flame out. Models up to 24 kW are able to heat at a rate of up to 12 l/min.

In order to prolong the life of the heater the manufacturer recommends:
