of injury.
!Please note
This symbol warns against the risk
of material losses and environmen-
tal pollution.
Note
Details identified by the word "Note"
contain additional information.
Target group
These instructions are exclusively inten-
ded for qualified contractors.
■Work on gas installations may only be
carried out by a registered gas fitter.
■Work on electrical equipment may only
be carried out by a qualified electrician.
■The system must be commissioned by
the system installer or a qualified per-
son authorised by the installer.
Regulations to be observed
■National installation regulations
■Statutory regulations for the prevention
of accidents
■Statutory regulations for environmental
protection
■Codes of practice of the relevant trade
associations
■Relevant country-specific safety regu-
lations
Safety instructions for working on the system
Working on the system
■Where gas is used as the fuel, close
the main gas shut-off valve and safe-
guard it against unintentional reopen-
ing.
■Isolate the system from the power sup-
ply, e.g. by removing the separate fuse
or by means of a mains isolator, and
check that it is no longer live.
■Safeguard the system against recon-
nection.
■Wear suitable personal protective
equipment when carrying out any work.

Danger
Hot surfaces and fluids can lead to
burns or scalding.
■Before maintenance and service
work, switch OFF the appliance
and let it cool down.
■Never touch hot surfaces on the
boiler, burner, flue system or pipe-
work.
!Please note
Electronic assemblies can be dam-
aged by electrostatic discharge.
Prior to commencing work, touch
earthed objects such as heating or
water pipes to discharge static
loads.
Repair work
!Please note
Repairing components that fulfil a
safety function can compromise the
safe operation of the system.
Replace faulty components only
with genuine Viessmann spare
parts.
Auxiliary components, spare and
wearing parts
!Please note
Spare and wearing parts that have
not been tested together with the
system can compromise its func-
tion. Installing non-authorised com-
ponents and making non-approved
modifications or conversions can
compromise safety and may invalid-
ate our warranty.
For replacements, use only original
spare parts supplied or approved by
Viessmann.

Safety instructions for operating the system
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.
■Notify your gas or electricity sup-
ply utility from outside the building.
■Have the power supply to the
building shut off from a safe place
(outside the building).
If you smell flue gas
Danger
Flue gas can lead to life threatening
poisoning.
■Shut down the heating system.
■Ventilate the installation site.
■Close doors to living spaces to
prevent flue gases from spread-
ing.
What to do if water escapes from the
appliance
Danger
If water escapes from the appliance
there is a risk of electrocution.
Switch OFF the heating system at
the external isolator (e.g. fuse box,
domestic distribution board).
Danger
If water escapes from the appliance
there is a risk of scalding.
Never touch hot heating water.
Condensate
Danger
Contact with condensate can be
harmful to health.
Never let condensate touch your
skin or eyes and do not swallow it.
Flue systems and combustion air
Ensure that flue systems are clear and
cannot be sealed, for instance due to
accumulation of condensate or other
external causes.
Ensure an adequate supply of combus-
tion air.
Inform system users that subsequent
modifications to the building characteris-
tics are not permissible (e.g. cable/pipe-
work routing, cladding or partitions).
Danger
Leaking or blocked flue systems, or
an inadequate supply of combus-
tion air can cause life threatening
poisoning from carbon monoxide in
the flue gas.
Ensure the flue system is in good
working order. Vents for supplying
combustion air must be non-seala-
ble.
Extractors
Operating appliances that exhaust air to
the outside (extractor hoods, extractors,
air conditioning units, etc.) can create
negative pressure. If the boiler is oper-
ated at the same time, this can lead to a
reverse flow of flue gas.

Danger
The simultaneous operation of the
boiler and appliances that exhausts
air to the outside can result in life
threatening poisoning due to a
reverse flow of flue gas.
Fit an interlock circuit or take suita-
ble steps to ensure an adequate
supply of combustion air.

Intended use
The burner must only be operated when installed in
the boiler. "Appliance" here refers to the boiler with
burner fitted.
The appliance is only intended to be installed and
operated in sealed unvented heating systems that
comply with EN 12828, with due attention paid to the
associated installation, service and operating instruc-
tions as well as the details in the datasheet.
It is only designed for the heating up of heating water.
Commercial or industrial usage for a purpose other
than the heating up of heating water shall be deemed
inappropriate.
Intended use presupposes that a fixed installation in
conjunction with permissible components designed for
this purpose has been carried out.
Every other use will be deemed to be inappropriate.
Any resulting losses are excluded from the manufac-
turer's liability.
Any usage beyond this must be approved by the man-
ufacturer for the individual case.
Intended use also includes the adherence to mainte-
nance and inspection intervals.
The burner must be installed in compliance with the
applicable regulations. The burner must be operated
only in well ventilated areas. Observe instructions for
installation and operation of the burner.

Product contains ceramic fibres
Danger
When working with high temperature insulating
materials that contain zirconium or aluminium
silicate ceramic fibres, fibre dust may
develop. This fibre dust can be harmful to
health.
Only trained personnel may adjust or replace
the insulation. Wear suitable protective clothing,
especially breathing equipment and safety gog-
gles.
Boiler inspection and maintenance
Steps that relate to the boiler are described in separate
instructions.

Checking the gas type
1. Check with your gas supply utility regarding the
gas type and Wobbe index (Wo).
The boiler can be operated in the following Wobbe
index ranges:
■With natural gas E:
12.0 to 16.1 kWh/m3 (43.2 to 58.0 MJ/m3)
■With natural gas LL: 10.0 to
13.1 kWh/m3(36.0 to 47.2 MJ/m3).
2. In the delivered condition, the burner is set up for
natural gas E. If required, convert the burner to a
different gas type in accordance with details provi-
ded by the gas supply utility. See the following
chapter.
3. Record the gas type in the report in the appendix.
