GETTING STARTED
Before switching ON
Before switching the boiler on please familiarize yourself with:
- how to isolate the boiler from the gas, water, and electricity
supplies;
- how to check and top-up – if necessary – the system water
pressure;
- the time clock or programmer;
- any external thermostats and their functions;
- the boiler controls.
Boiler controls (see Fig. 2)
The boiler controls are situated on the lower front of the boiler. The
boiler controls include:
- Pressure gauge
- Green led (burner ON)
- 2-digit LED display
- Red led (fault indicator)
- Temperature selector space heating
- Mode selector switch
- Temperature selector Domestic Hot Water
The pressure gauge shows the current pressure of your heating
system, the gauge should be typically set between 15-22 psi (1-
1.5 bar). When the boiler is operating the gauge may rise or fall
slightly, this is quite normal. The minimum permissible level for the
safe and efficient operation of the boiler is 7 psi (0.45 bar). Should
the pressure fall below 7 psi (0.45 bar), the boiler may lockout.
The boiler mode selector is used to switch the boiler to the
various operating modes:
NOTE
THE BOILER FREEZE PROTECTION IS ACTIVE IN ALL OF
THE ABOVE MODES.
The temperature selector DHW can be used to adjust the
temperature of the water in the storage tank. The temperature
range is adjustable between 95°F and 140°F (35°C and 60°C)
for the tank storage temperature.
The temperature selector CH can be used to adjust the
temperature of the radiators or floor heating. The temperature
range is adjustable between 104°F and 176°F (40°C and 80°C)
for standard heating systems.
Moreover if floor heating mode is selected (by using the relative
jumper), the temperature range for heating mode can be modified
between 68°F and 113°F (20°C and 45°C).
The 2-digit LED display normally shows the operating tempera-
ture of the boiler (or storage tank temperature if fitted and the mode
selector in the proper position), however it can also display
additional characters or flashing numbers to signify specific
operating modes or fault codes.

example:
When the status indicator (Green) is lit it indicates that the flame
is detected and the burner is fully in ON status.
When the
fault indicator (Red) is lit it indicates that the boiler has
identified a possible fault and performed a safety shut-down.
Lighting the boiler
Ensure the gas and electrical supply to the boiler are turned on.
When power is restored to the boiler and/or the boiler is powered
for the first time, the boiler start a series of checking and on the
display appears a series of letters and numbers. If the checking
is ok, the boiler start an automatic purge cycling for 2 minutes, the
display will show as per Fig. 4.
After this cycling the boiler is ready to be used.
Turn the mode selector switch to the
ON position. When there is
a request for heating or hot water, the boiler will begin an ignition
sequence. When the boiler reaches the set temperature, the
burner will go off for a minimum period of approximately 3 minutes.
WHEN THE ROOM THERMOSTAT HEATING REQUEST HAS
BEEN SATISFIED, THE BOILER WILL SWITCH OFF
AUTOMATICALLY.
Adjusting the operating temperature
Rotate the temperature selector – clockwise to increase, counter-
clockwise to decrease – to the desired temperature setting. The
temperature can be set between 104°F and 176°F (40°C and
80°C) standard heating systems and between 68°F and 113°F
(20°C and 45°C) under-floor heating systems.
NOTE
If the boiler fails to ignite during the ignition sequence, it will enter
a lockout condition. Should this occur, please allow a period of at
least two minutes before resetting the boiler.
Adjusting the hot water temperature
Rotate the temperature selector – clockwise to increase, counter-
clockwise to decrease – to the desired temperature setting. The
storage temperature can be set from a minimum of 95°F (35°C)
to a maximum of 140°F (60°C) if the tank has a temperature
sensor; in the case of a tank with thermostat the storage tempe-
rature is set directly on the tank thermostat.
