F P - “10
Boiler frost protection-boiler will re if temperature is below 5ºC.
= temperature shown for example purposes only
During normal operation the burner on indicator (F) will remain
illuminated when the burner is lit.
Note: If the boiler fails to light after ve attempts the fault code
will be displayed (refer to Fault Code page).
OPERATION MODES
Winter Conditions -
(Central Heating and Domestic Hot Water required)
Set the mode knob (C) ‘ (winter).
The boiler will re and supply heat to the radiators but will give
priority to domestic hot water on demand.
The domestic hot water preheat will operate with the
preheat
button pressed so that the reheat indicator (G) is on.
Summer Conditions - (Domestic Hot Water only required)
Set the mode knob (C) to ‘
(summer).
Set the central heating demand on the external controls to OFF.
The domestic hot water preheat will operate with the
preheat
button pressed so that the preheat indicator (E) is on.
Boiler Off
Set the mode knob (C) to ‘OFF’. The boiler mains power supply
must be left on to enable frost protection (see Frost Protection).
PREHEAT - DOMESTIC HOT WATER
The domestic hot water heat exchanger within the boiler can be
kept preheated to provide faster delivery of hot water at the tap.
This is achieved by pressing the ‘
preheat
button
(G)
so that
the
preheat indicator (E) is on
.
The boiler will operate periodically for a few seconds to maintain
the domestic hot water heat exchanger in a preheated condition.
The average time period between operation is 90 minutes. This
may vary considerably due to the surrounding ambient temperature
of the boiler. The boiler will operate whenever there is a demand
for domestic hot water.
If standard hot water delivery is satisfactory press the ‘
preheat
button (G) so that
the preheat indicator (E) is off
.
CONTROL OF WATER TEMPERATURE
Domestic Hot Water
The domestic hot water temperature is limited by the boiler
controls to a maximum temperature of 65
º
C, adjustable via the
domestic hot water temperature knob (A).
Approximate temperatures for domestic hot water:
Knob Setting Hot Water Temperature (approx.)
Minimum 40ºC
Maximum 65ºC
Due to system variations and seasonal temperature uctuations
domestic hot water ow rates/temperature rise will vary, requiring
adjustment at the tap : the lower the ow rate the higher the
temperature, and vice versa.
Central Heating
The boiler controls the central heating radiator temperature to a
maximum of 80
o
C, adjustable via the central heating temperature
knob (B).
Approximate temperatures for central heating:
Knob Setting
Central Heating Radiator Temperature (approx.)
Minimum 30ºC
Maximum 80ºC

3. SYSTEM WATER PRESSURE
The system pressure gauge (K - 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. If unable to do so or if the pressure
continues to drop a Gas Safe Registered Engineer or in IE a
Registered Gas Installer (RGII) should be consulted.
THE BOILER WILL NOT OPERATE IF THE PRESSURE
HAS REDUCED TO LESS THAN 0.3 BAR UNDER THIS
CONDITION.
4. CONDENSATE DRAIN
This appliance is tted with a siphonic condensate trap
system that reduces the risk of the appliance condensate
from freezing. However should the condensate pipe to this
appliance freeze, please follow these instructions:
a. If you do not feel competent to carry out the defrosting
instructions below please call your local Gas Safe
Registered installer for assistance.
b.
If you do feel competent to carry out the following instructions
please do so with care when handling hot utensils. Do not
attempt to thaw pipework above ground level.
If this appliance develops a blockage in its condensate pipe,
its condensate will build up to a point where it will make a
gurgling noise prior to locking out an “L2” fault code. If the
appliance is restarted it will make a gurgling noise prior to it
locking out on a failed ignition “L2” code.
To unblock a frozen condensate pipe;
1. Follow the routing of the plastic pipe from its exit point on
the appliance, through its route to its termination point.
Locate the frozen blockage. It is likely that the pipe is
frozen at the most exposed point external to the building
or where there is some obstruction to ow. This could be
at the open end of the pipe, at a bend or elbow, or where
there is a dip in the pipe in which condensate can collect.
The location of the blockage should be identied as
closely as possible before taking further action.
2. Apply a hot water bottle, microwaveable heat pack or a
warm damp cloth to the frozen blockage area. Several
applications may have to be made before it fully defrosts.
Warm water can also be poured onto the pipe from a
watering can or similar. DO NOT use boiling water.
3. Caution when using warm water as this may freeze and
cause other localised hazards.
4.
Once the blockage is removed and the condensate can ow
freely, restart the appliance. (Refer to “To Start the Boiler”)
5. If the appliance fails to ignite, call your Gas Safe
Registered engineer.
Preventative solutions
During cold weather, set the central heating temperature knob
(B) to maximum, (Must return to original setting once cold
spell is over).
Place the heating on continuous and turn the room
thermostat down to 15ºC overnight or when unoccupied.
(Return to normal after cold spell).
EFFICIENT HEATING SYSTEM OPERATION
The boiler is a high efciency, 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 ue gases when operating
most efciently. To operate your boiler efciently (using less gas)
turn the central heating temperature knob (B) to the ‘
e ‘ position
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 tted to the system then
the central heating temperature knob (B) 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 tted 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 tted) 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 9) press the restart button (H). The boiler will repeat its
ignition sequence. If the boiler still fails to start consult a Gas Safe
Registered Engineer or an IE Registered Gas Installer (RGII).
MAINS POWER OFF
To remove all power to the boiler the mains power switch must be
turned off.
