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 fitted with automatic electronic ignition so there is no pilot to worry about.
Pull down cover to reveal control facia panel.
Make sure that the gas, water and electricity supplies to the boiler are turned on.
The boiler pressure gauge (6) should read at least 1 bar.
Low pressure will be indicated by the bottom red light on the left hand side of the facia illuminating (
bar
).
Hot Water Only - “SUMMER”
(
)
To obtain hot water only from the boiler, turn switch (3) to the on position. The top green light on the left
side of the control panel is illuminated (power on
).
Turn the temperature regulator (2) to the
position. Open a hot water tap, green light (tap symbol)
comes on, fan starts and burner will light. Indicated by flame symbol, green light coming on. The
temperature of the hot water can be adjusted by turning the hot water thermostat (1) clockwise to increase
and anti-clockwise to decrease the water temperature.
Heating and Hot Water - "WINTER”
(
)
To obtain heating from the boiler, turn the temperature regulator (2) clockwise to the maximum position,
ensure that any other heating controls e.g. room thermostats, clock etc. are in the on position.
The boiler may be in heating delay of three minutes as indicated by the red light (egg timer symbol) on
the left of the facia panel. When this light goes out the green light (radiator symbol) will come on. The
fan and pump will run and the burner will light indicated by the green flame symbol light. Adjust the
temperature regulator to the desired setting. (In winter do not run boiler below 50
°
C). If a hot water tap
is opened whilst the boiler is running for heating the pump will stop, suspending the heating phase and
the boiler will give priority to hot water production. When the tap is closed the boiler will go into a three
minute delay cycle before resuming for heating.
