The boiler is designed for use with two types of gas: natural gas NG or propane (LPG). The type of gas can be selected
when purchasing the boiler or the appliance can be converted later on site by a competent person. It operates with
technologically advanced systems such as electronic adjustment, safety and control devices.
The boiler is fi tted with automatic electronic ignition so there is no pilot to worry about.

Turn up the cover to reveal the control panel.
a e sure that the gas, water and electricity supplies to
the boiler are turned on.
To obtain heating from the boiler, turn the temperature
regulator ( ) cloc wise to the desired position, ensure that
any other heating controls e.g. room thermostats, cloc
etc. are in the on position.
The boiler fl ow temperature is adjusted by from panel nob
(see fi g. 4 ) from 60°C to 8 °C.
Once the fl ow temperature reached set value, the burner
goes out and the electronic system imposes a delay of
minutes before allowing re-ignition. Once heat demand is
fi nished, pump and burner go out.
In "gravity circulation system" (see paragraph
pump signal is an input for electronic device. If the pump
is not running and there is heat demand the temperature
control is set on 50°C and after
time, this level switches to a fi xed value of 70°C. With the nob in "OFF" position the call for heat is disabled;
but if the temperature in the ambient comes below 5°C, a frost protection overrules the off-state and a heat
demand is generated.
