Maintenance

7.1

General
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
AGENTS.

7.2

Maintenance Instructions
1. The central heating installation should be checked regularly.
Proceed as follows:
• Check the water pressure in the central heating installation.
If the water pressure is lower than 0.7 bar, the water
must be topped up. If necessary: top up the CH
installation (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.

Maintenance

7.3

Re-pressurising the System
1. If the water pressure is too low, the installation must be
re-pressurised.
2. The normal operating water pressure is between 1 and 2 bar.
If the pressure exceeds 3 bar the safety pressure valve will
operate and a fault is indicated (E117 displayed). Contact your
installer.
3. It may be necessary to repressurise the system occasionally
(when the water pressure falls below 0.7 or E118 displayed). A
filling device (the filling loop) will be fitted on the system. This
will be on the boiler itself, or on pipework near to the boiler.
If the water pressure requires regular re-pressurising a
fault or leak is indicated. Seek advice from your installer.
4. If you are unsure of its position, or cannot identify it, consult
the installer who fitted the boiler.

Pressure Gauge

5. The filling loop consists of two isolating taps and a separate
filling pipe with connection fittings.
6. Only when repressurising should the filling pipe be connected
between the two taps. Ensure that the nuts on the pipe ends
are tightened onto the taps.

7. Fully open one of the taps first, and then while watching the
pressure gauge, carefully open the second tap.

Environmental

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 boiler external controls.
Turn down room thermostats by 1°
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 thermostat are available. The
thermostat type and setting affect the total energy consumption.
A few tips:
Fully opening or closing thermostatic radiator valves results
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 holidays.
