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.

control 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.
