Operating Principle
4.2.1
in Operation
1. Whilst the boiler is in operation cooled flue gases are
discharged through the flue gas discharge pipe. This may
appear as a cloud of steam which is normal.
2. Condensed water is discharged from the boiler heat
exchanger into a pipe (the condensate drain). This pipe must
never be altered or re-routed except by a qualified professional.

indicator Lights (Fig. 5)
The colour of the status light
on the boiler control panel and
the number of times that it flashes indicates whether the boiler is
working normally, has a problem or requires servicing.
See Section 8.1. for details of the fault conditions.
Boiler Operating The
light will flash orange at EVERY
heating demand. The number of flashes will correspond with the
heat output of the boiler. This is normal and does not indicate a
fault condition. During normal running
illuminates green and
blinks off momentarily every seven seconds approximately to
show the boiler is running normally and supplying heat (Fig. 6).

1. The boiler does not require any special maintenance.
However, the boiler must be serviced annually in accordance
with the Installation and Service Manual and the relevant
section of the Benchmark Service Record completed in order to
maintain the warranty.
Taking out a maintenance contract is recommended.
CaUTiOn
Maintenance operations must be performed by a
qualified competent person.
Use only genuine spare parts.
2. The painted panels should be wiped with a damp cloth and
then dried completely. DO nOT USE aBRaSiVE CLEaning

7.2
Maintenance instructions
1. The central heating system should be checked regularly.
Proceed as follows:
For Sealed Systems
If the water pressure is lower than 0.7 bar, the water
must be topped up. If necessary: top up the CH system
(recommended water pressure between 1 and 2 bar).
• Check radiators for leaks and (especially in damp areas) for
rust.
• Open and close the radiator valves several times a year to
ensure they can still be rotated.
• Only clean the outside of the boiler with a damp cloth. Do not
use abrasive cleaning agents.
CaUTiOn
Only a qualified installer may clean the inside of the
boiler.

7.3
Filling the System
The boiler will be installed on either an open-vented or sealed
(pressurised) heating system. If you are unsure which type of
system you have consult your installer.
Sealed systems may require periodic re-pressurisation. If this is
required on a regular basis a fault or leak is indicated. Seek
advice from your installer.

Switch off or disconnect the boiler’s electrical isolation point.
Wait until all the radiators are cold.
Connect a drain hose to the lowest draining point. Place the
end of the hose in a drain or at a place where drained
water will not cause any damage.
Open the CH system drain valve. Drain the system.

Troubleshooting
8.2
Fault Finding
1. If the boiler is not working, check section 5.1 Operation Checking Procedure & Basic Fault
Identification or the fault finding table. Contact your Installer.
Problem
Possible Causes
There is no domestic hot water
and/or the radiators are cold.
Check that the boiler is being supplied with power
(all controls set to ON).
Check the fuses and the switches.
If possible check whether the gas cock is properly
open.
If the property has a prepayment meter ensure it
has sufficient credit.
The boiler is not working.
Check if the Fault - Lock-out is illuminated. See
Section 8.1 to reset.
The domestic hot water is not
hot enough.
The boiler temperature setting is below the
cylinder thermostat setting.
The radiators are not hot
enough.
The radiator valves are not open.
The temperature set point for the heating is too
low (check boiler & room thermostat).

CaUTiOn
Only qualified professionals are authorised to
work on the appliance and system to decommission.
1. If your the boiler needs to be decommissioned either
temporarily or permanently the following should be performed:
•
Switch off the boiler.
•
Switch off the boiler’s electrical connection.
•
Close the boiler gas valve.
•
Drain the CH system.
Seek the advice of your installer.

Removal and disposal of the boiler must be carried
out by a qualified installer in accordance with local
and national regulations.

11.1 Energy Saving
Tips on saving energy:
Do not cover radiators. Do not hang curtains in front of
radiators.
Install reflective panels behind the radiators to prevent heat
losses.
Insulate the pipes in rooms that are not heated (cellars and
lofts).
Install loft insulation & double glazing.
Use draught excluders where necessary.
Upgrade any older external controls.
Turn down room thermostats by 1°C
Turn off radiators in rooms not in use.
Do not run hot (or cold) water pointlessly.
Fit a water-saving shower head to save up to 40 % energy.
Take showers rather than baths. A bath consumes twice as
much water and energy.
11.2 Room Thermostats and Settings
Various models of room thermostats are available. The
thermostat type and setting affect the total energy consumption.
A few tips:
Fully opening or closing thermostatic radiator valves result
in unwanted temperature fluctuations. Turn the thermostat knob
or valve higher or lower in small steps.
Lower the thermostat to approximately 20°C. This reduces
heating costs and energy consumption.
When rooms are to be aired, lower the thermostat well in
advance.
When setting thermostats or programmers take account of
days when nobody will be in and of holidays.
