Working on the system
When using gas as fuel, also close the
main gas shut-off valve and safeguard
against unauthorised reopening.
Isolate the system from the power sup-
ply and check that it is no longer 'live',
e.g. by removing a separate fuse or by
means of a main isolator.
Safeguard the system against unau-
thorised reconnection.
!Please note
Electronic modules can be dam-
aged by electrostatic dis-
charges.
Touch earthed objects, such as
heating or water pipes, to dis-
charge static loads.
Repair work
!Please note
Repairing components that fulfil a
safety function can compromise
the safe operation of your heating
system.
Replace faulty components only
with original Viessmann spare
parts.
Ancillary components, spare and
wearing parts
!Please note
Spare and wearing parts that
have not been tested together
with the heating system can com-
promise its function. Installing
non-authorised components and
non-approved modifications or
conversions can compromise
safety and may invalidate our
warranty.
For replacements, use only orig-
inal spare parts supplied or
approved by Viessmann.

Installation information
!Please note
To prevent material losses, install
the combi cylinder in a draught-
free room free from the risk of
frost.
Otherwise the combi cylinder will
have to be drained if there is a risk
of frost and it is not in use.
!Please note
The thermal insulation must not
be able to come into contact with
naked flames.
Exercise caution when welding
and soldering.
Provide adequate clearance from the
wall so that the thermostat can be oper-
ated (if installed).

Information regarding the safety
valve
The system must be equipped with a
type-tested diaphragm safety valve as
protection against overpressure.
Permiss. operating pressure: 10 bar.
The connection diameter of the safety
valve must be R ¾ (DN 20).
Consequently, the max. permissible
heat input would be 150 kW. If the heat
input of the Vitocell exceeds 150 kW,
select a larger safety valve that is able to
cope with the respective heat input (see
DIN 4753-1, issue 3/88, section 6.3.1).
Install the safety valve in the cold water
pipe. It must not be able to be isolated
from the DHW cylinder.
The pipework between the safety valve
and the DHW cylinder must not be
restricted in any way.
The safety valve discharge pipe must not
be able to be closed. Expelled water
should be safely and visibly drained into
a sewer. Place a sign close to the safety
valve discharge pipe or on the safety
valve itself with the following inscription:
"For safety reasons, water may be dis-
charged from the discharge pipe during
heating. Never seal off!"
Install the safety valve above the top
edge of the DHW cylinder.
Connecting the heating water side
Adjust the thermostat and high limit
safety cut-out so that the DHW tem-
perature in the cylinder never exceeds
95 ºC.
Connect all pipework with detachable
fittings.
Permissible temperatures
on the solar side: 140 °C
on the heating water side: 110 °C
Permissible operating pressure
on the solar side: 10 bar
on the heating water side: 3 bar
Test pressure
on the solar side: 16 bar
on the heating water side: 4.8 bar
1. Install the flow pipes with an incline
and fit an air vent valve at the highest
point.
2. Install control equipment that
ensures the permissible tempera-
tures on the heating side are main-
tained.
3. Install an additional type-tested high
limit safety cut-out, if none has been
installed so far in the system. For this,
use a twin thermostat (temperature
limiter and high limit safety cut-out).
4. Seal all unused connections with
plugs or caps.
