effiCient HeAtinG SySteM oPeRAtion

The boiler is a high efficiency, condensing appliance which will
automatically adjust its output to match the demand for heat.
Therefore gas consumption is reduced as the heat demand is
reduced.
The boiler condenses water from the flue gases when operating
most efficiently. To operate your boiler efficiently (using less gas)
turn the central heating temperature knob (C) to the '
or lower. In winter periods it may be necessary to turn the knob
towards the 'max' position to meet heating requirements. This will
depend on the house and radiators used.
Reducing the room thermostat setting by 1ºC can reduce gas
consumption by up to 10%.

WeAtHeR CoMPenSAtion

When the Weather Compensation option is fitted to the system
then the central heating temperature knob (C) becomes a method
of controlling room temperature. Turn the knob clockwise to
increase room temperature and anti-clockwise to decrease room
temperature. Once the desired setting has been achieved, leave
the knob in this position and the system will automatically achieve
the desired room temperature for all outside weather conditions.

boileR fRoSt PRoteCtion

The boiler is fitted with frost protection that operates in all modes,
provided the power supply to the boiler is always turned on. If the
water in the boiler falls below 5ºC, the frost protection will activate
and run the boiler to avoid freezing . The process does not
guarantee that all other parts of the system will be protected.
If a system frost thermostat has been installed, the boiler must be
set in winter mode, ' ', for the system frost protection to run.
If no system frost protection is provided and frost is likely during a
short absence from home it is recommended to leave the system
heating controls or built in programmer (if fitted) switched on and
run at a reduced temperature setting. For longer periods, the entire
system should be drained.

boileR ReStARt

To restart the boiler, when directed in the listed fault codes (see
section 8), turn the mode knob (D) to 'restart' position and
IMMEDIATELY turn knob back to required setting. The boiler will
repeat its ignition sequence. If the boiler still fails to start consult a
Gas Safe Registered Engineer or in IE a Registered Gas Installer
(RGII).

MAinS PoWeR off

To remove all power to the boiler the mains power switch must be
turned off.

3. SySteM WAteR PReSSURe

The system pressure gauge (G - see page 3)
indicates the central heating system pressure.
If the pressure is seen to fall below the original
installation pressure of 1-2 bar over a period of
time and continue to fall then a water leak may
be indicated. In this event re-pressurise the
system as shown below. If unable to do so or if
' position
the pressure continues to drop a Gas Safe Registered Engineer or in
IE a Registered Gas Installer (RGII) should be consulted.

6. Wait for the pressure gauge to reach 1 to 1.5 bar.
7. Once pressure is reached turn valves

8. Disconnect the filling loop, replace cap and plug. Note there
can be some water spillage at this point.
