Workingonthesystem
&When using gas as fuel, also close
the main gas shut-off valve and
safeguard against unauthorised
reopening.
&Isolate the system from the power
supply 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
unauthorised reconnection.
!Please note
Electronic modules can be
damaged by electro-static dis-
charges.
Touch earthed objects, such as
heating or water pipes, to dis-
charge static loads.
Repair work
!Please note
Repairing components which
fulfil a safety function can com-
promise 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 which
have not been tested together
with the heating system can
compromise its function. Instal-
ling non-authorised compo-
nents and non-approved
modifications/conversion can
compromise safety and may
invalidate our warranty.
For replacements, use only ori-
ginal spare parts from
Viessmann or those which are
approved by Viessmann.

Filling the heating system from the heating water side
1. Close shut-off valve Ain the
return line.
2. When using a top-mounted Modu-
lar-Divicon (accessory):
Set the mixer lever to "OPEN"
(red).
3. Fill the system via on-site filling
connection Bon the heating
return, until it is fully vented.
4. Open shut-off valve Aagain.

Separating the neutralising system or active charcoal filter
(if installed) from the boiler and connecting the drain hose
1. Separate hose Ato the neutralis-
ing system from siphon B.
2. Remove siphon Bfrom the con-
densate drain.
3. Connect drain hose Con the con-
densatedrainandrunthehosetoa
drainage system.

Checking the neutralising system (if installed)
Check the pH value of the condensate
with a pH test strip. Replace the gran-
ulate if the pH value < 6.5.
Note
Part no. for pH test strips: 9517 678.
Observe the manufacturer's instruc-
tions regarding the neutralising sys-
tem.
Checking the active charcoal filter (if installed)
Observe the manufacturer's instruc-
tions regarding the active charcoal fil-
ter.
Checking the connections on the flue gas side for tightness
Note
Traces of condensate indicate a leak.
1. Remove insulation strip Aand
pull out thermal insulation mat Ba
little.
2. Check the heat exchanger for tight
fit.
3. Check the connector on the heat
exchanger for leaks.

Cleaning the heating surfaces
Note
Carry out the standard cleaning from
the front of the boiler (through the
combustion chamber).
In case of severe contamination (e.g.
through incorrect burner adjustment),
remove the heat exchanger to clean
the boiler.
1. Remove contamination from the
connector using a vacuum cleaner.
2. Thoroughly flush the heating sur-
face with water.
!Please note
Prevent components that are in
contact with hot gases from
being scratched or otherwise
damaged. Prevent components
that are in contact with hot
gases from coming into contact
with pure iron, otherwise corro-
sion damage can result.
Neveruseawirebrushor
sharp objects. Use plastic
brushes, if required.
For conventional cleaning, flush the
heating surfaces thoroughly with
water. However, youmayuseclean-
ing agents if you notice stubborn resi-
dues, surface discolouration or soot
deposits.
For this, observe the following:
&Only use solvent-free cleaning
agents. Ensure that no cleaning
agent enters between the boiler
body and the thermal insulation.
&Remove soot deposits with alkaline
agents containing surfactants (e.g.
Fauch 600*1).
&Combustion residues may create
thin, yellow-brown surface disco-
louration as well as hard deposits
that may only become visible after
removing the soot deposits. Use
slightly acidic, chlorine-free clean-
ing agents based on phosphoric
acid to remove surface discoloura-
tion and hard deposits (e.g. Antox
75 E*1).
&Remove loose deposits from the
heat exchanger; flush the heating
surface thoroughly with water.

Cleaning the condensate drain and siphon and reconnecting
to the drainage system
Check that the hoses are routed with-
out kinks and that the condensate can
freely drain off.
