2.5 Temperature regulation
The appliance is under water supply
pressure (maximum 8 bar). The amount
of cold water that is added is equal to
the amount of hot water used. The gas
control block automatically regulates the
gas supply. The main burner will ignite as
soon as a reduction in water temperature
is sended by the thermostat. The main
burner will shut down as soon as the
preset temperature is achieved.
At high water temperatures there is more
scale buildup in the appliance. It is for
this reason that it is recommended to
place the temperature control knob in
position of
60 °C as the accumulation of scale will
be reduced.
2.6 converting to another
type of gas
For conversion of the appliance from
natural gas to another type of gas, or
visa versa, it is necessary to exchange
the pilot injector and the main injector.
The conversion may only be executed by

Procedure:
1. Shut the heater down. Close the main
inlet gas valve and switch off the
electricity supply at the main switch;
2. Remove the burner assembly;
3. Replace the injectors with the correct
injectors from the conversion set.

Remark:
- When conversion of the appliance
from natural gas to another type of
