Safety instructions for operating the system
Damage to the appliance
Danger

safety hazard.
Check the appliance for external
damage. Never start up a damaged
appliance.
If you smell gas
Danger
Escaping gas can lead to explo-
sions which may result in serious
injury.
■Do not smoke! Prevent naked
flames and sparks. Never switch
lights or electrical appliances on
or off.
■Close the gas shut-off valve.
■Open windows and doors.
■Evacuate any people from the
danger zone.

If you smell flue gas
Danger
Flue gas can lead to life threatening
poisoning.
■Shut down the heating system.
■Ventilate the installation site.
■Close all doors in the living space.
If there is a fire
Danger
Fire presents a risk of burns and
explosion.
■Shut down the heating system.
■Close the shut-off valves in the
fuel supply lines.
■Use a tested fire extinguisher,
class ABC.
What to do if water escapes from the
appliance
Danger
If water escapes from the appliance
there is a risk of electric shock.
■Switch off the heating system at
the external isolator (e.g. fuse
box, domestic distribution board).
■Notify your heating contractor.
If the heating system develops a fault
Danger
Fault messages indicate faults in
the heating system. If faults are not
rectified, they can have life threat-
ening consequences.
Do not acknowledge fault mes-
sages several times in quick suc-
cession. Inform your heating con-
tractor so the cause can be ana-
lysed and the fault rectified.
Installation room requirements
Danger
Sealed vents result in a lack of
combustion air. This leads to incom-
plete combustion and the formation
of life threatening carbon monoxide.
Never cover or close existing vents.
Do not make any subsequent modi-
fications to the building characteris-
tics that could affect safe operation
(e.g. cable/pipework routing, clad-
ding or partitions).
Danger
Easily flammable liquids and mate-
rials (e.g. naphtha/petrol, solvents,
cleaning agents, paints or paper)
can cause deflagration and fire.
Never store or use such materials
in the boiler room or in direct prox-
imity to the heating system.
!Please note
Incorrect ambient conditions can
lead to heating system damage and
can put safe operation at risk.
■Ensure ambient temperatures are
above 0 °C and below 35 °C.
■Prevent air contamination by halo-
genated hydrocarbons (e.g. as
contained in paints, solvents or
cleaning fluids) and excessive
dust (e.g. through grinding/polish-
ing work).
■Avoid continuously high humidity
levels (e.g. through continuous
drying of washing).
Extractors
The operation of appliances that extract
air to the outside (cooker hoods, extrac-
tors, air conditioning units, etc.) can cre-
ate negative pressure. If the boiler is
operated at the same time, this can lead
to a reverse flow of flue gas.

Danger
The simultaneous operation of the
boiler and appliances that extract
air to the outside can result in life
threatening poisoning due to a
reverse flow of flue gas.
Take suitable steps to ensure an
adequate supply of combustion air.
If necessary, contact your contrac-
tor.

Terminology
To provide you with a better understanding of the func-
tions of your control unit, some terminology is
explained. This information can be found in chapter
"Terminology" in the Appendix.
Intended use
The appliance is intended solely for installation and
operation in sealed unvented heating systems that
comply with EN 12828, with due attention paid to the
associated installation, service and operating instruc-
tions. It is only designed for heating up heating water
that is of potable water quality.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for a purpose other
than heating the building or DHW shall be deemed
inappropriate.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.
