information.
Target group
These instructions are exclusively intended for author-
ised contractors.
■Work on electrical equipment must only be carried
out by a qualified electrician.
■The system must be commissioned by the system
installer or a qualified person 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
■All relevant safety regulations as defined by DIN, EN,
DVGW, VDE and locally applicable standards
aÖNORM, EN and ÖVE
cSEV, SUVA, SVTI and SWKI
Safety instructions for working on the system
Working on the system
■Isolate the system from the power supply (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 reconnection.
Danger
Hot surfaces can cause burns.
■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 pipework.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing work, touch earthed
objects such as heating or water pipes, to dis-
charge static loads.
Repair work
!Please note
Repairing components that fulfil a safety func-
tion 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 tes-
ted together with the system can compromise its
function. Installing non-authorised components
and making non-approved modifications or con-
versions can compromise safety and may inva-
lidate our warranty.
For replacements, use only original spare parts
supplied or approved by Viessmann.

Safety instructions for operating the system
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 spreading.
What to do if water escapes from the appliance
Danger
When water escapes from the appliance there is
a risk of electrocution.
Switch off the heating system by means of an
external isolator (for example fuse box, domestic
power distribution).
Flue systems and combustion air
Ensure that flue systems are clear and cannot be
sealed, for instance due to accumulation of conden-
sate or other causes. Ensure an adequate supply of
combustion air.
Instruct system users that subsequent modifications to
the building characteristics are not permissible (e.g.
cable/pipework routing, cladding or partitions).
Danger
Leaking or blocked flue systems, or an inade-
quate supply of combustion 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-
closable.
Extractors
Operating appliances that extract air to the outside
(cooker hoods, extractors, air conditioning units, etc.)
can create negative pressure. If the boiler is operated
at the same time, this can lead to reverse flow of the
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
reverse flow of the flue gas.
Fit an interlock circuit or take suitable steps to
ensure an adequate supply of combustion air.

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.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and will result in an exclusion of liability. Incorrect
usage also occurs if the components in the heating
system are modified from their intended use (e.g. if the
flue gas and ventilation air paths are sealed).

Operating instructions, service instructions –
control unit and burner
1. Check that the ventilation air aperture in the instal-
lation room is open.
2. Check the pre-charge pressure of the expansion
vessel.
If the pre-charge pressure of the expansion vessel
is lower than the static system pressure, top up
with sufficient nitrogen to raise the pre-charge
pressure higher (0.1 to 0.2 bar/10 to 20 kPa) than
the static system pressure.
The static pressure corresponds to the static head.
3. Open the check valves.
4.

AFilling/draining
Fill the heating system with water and vent it until
the charge pressure is higher (0.1 to 0.2 bar/10 to
20 kPa) than the pre-charge pressure of the
expansion vessel (see page 17).
Permiss. operating pressure: 3 bar (0.3 MPa)
Note
Let the heating circuit pump run whilst filling in
order to vent the indirect coils.

Mark the charge pressure at pressure gauge A.
6. Return the check valves to their operating position.
7. Open the oil shut-off valves.
8. Fill trap with water (see page 16).
Fill water
According to EN 1717 with DIN 1988-100, as a heat
transfer medium for DHW heating, the heating water
must meet fluid category ≤ 3. This requirement is met if
water of potable quality is used as heating water. For
example, if additives are used, the additive manufac-
turer must specify which category the treated heating
water comes under.

!Please note
Unsuitable fill water increases the level of
deposits and corrosion and may lead to appli-
ance damage.
■Flush the heating system thoroughly before
filling.
■Only use fill water of potable water quality.
■Special antifreeze suitable for heating systems
can be added to the fill water. The antifreeze
manufacturer must verify its suitability.
■Fill and top-up water with a water hardness in
excess of the following values must be soft-
ened, e.g. with a small softening system for
heating water.
Total permissible hardness of the fill and top-up water
Total heating output Specific system volume
kW < 20 l/kW ≥ 20 l/kW to < 50 l/kW ≥ 50 l/kW
≤ 50 ≤ 3.0 mol/m3 (16.8 °dH) ≤ 2.0 mol/m3 (11.2 °dH) < 0.02 mol/m3 (0.11 °dH)
> 50 to ≤ 200 ≤ 2.0 mol/m3 (11.2 °dH) ≤ 1.5 mol/m3 (8.4 °dH) < 0.02 mol/m3 (0.11 °dH)
