1.2Technical safety equipment

1.2.1 Gas control valve

The water heater is equipped with a gas control wich regulates the flow of gas to the burner. The gas block is equipped with a safety valve, gas valve and burner control (on a standard natural gas setting). To ensure improved ignition the gas control valve opening mechanism is fitted with a delay (softlite).

The gas control block is suitable for gasses from the first, second and third gas family. The maximum inlet pressure is 60 mbar.

The automatic incandescent ignition (hot surface) ensures that the burner ignites as soon as there is a demand for heat.

1.2.2Control panel

Temperature control for the water heater is housed in the control panel (See figur 2). For safety purposes, heaters are always fitted with two thermostats: a control thermostat is adjustable between 40 °C and 80 °C and a safety thermostat 90 °C. The control panel is fitted with an ON/OFF switch (I/0). At setting ”I”, the gas control is activated on the basis of heat demand from the control thermostat. At setting ”0” the heater is switched off.
