General information
Safety instructions
Please follow these safety instructions closely to prevent accidents and
material losses.
Work on the equipment
Installation, initial start-up,
inspection, maintenance and repairs
must only be carried out by a
competent person (heating
engineer/installation contractor).
Before working on the equipment/
heating system, isolate the mains
electrical supply (e.g. by removing a
separate mains fuse or by means of
a mains electrical isolator) and
safeguard against unauthorised
reconnection.
When using gas as fuel, also close
the main gas shut-off valve and
safeguard against unauthorised
reopening.
Work on gas equipment
This must only be carried out by an
approved contractor.
Please observe all commissioning
work specified for gas installations to
TRGI or TRF and all local regulations.
Please observe all commissioning
work specified for gas systems.
Repair ork
It is not permitted to carry out
repairs on parts that fulfil a safety
function.
Use only original Viessmann spare
parts, or equivalent parts that have
been approved by Viessmann.
Initial start-up
The initial start-up must be carried
out by the system installer or a
designated commissioning engineer.
All actual values should be recorded
in a commissioning/service report.
Instructing the system user
The system installer must hand the
operating instructions to the system
user and instruct him/her in the
operation of the system.
¨ĂSafety instruction
Denotes information which must be
observed to prevent accidents and
material losses.

Initial start-up, inspection and maintenance
Initial start-up
Operating instructions, service instructions ć control unit and burner
1. Check that the boiler room
ventilation aperture is open.
2. Check the inlet pressure of the
diaphragm expansion vessel.
If the inlet pressure of the
diaphragm expansion vessel is
lower than the static system
pressure, top up with enough
nitrogen to raise the inlet pressure
higher than the static system
pressure (0.1 to 0.2Ăbar).
3. Open the check valves.
4. Top up your heating system with
water and vent until the filling
pressure is higher (0.1 to 0.2Ăbar)
than the inlet pressure of the
diaphragm expansion vessel.
Permiss. operating pressureĂ Ă Ăbar
. . .
5. Mark this pressure on pressure
gaugeĂA.
6. Return the check valves to their
operating position.
7. Open the oil or gas shut-off valves.
Operating and service documents
1. Complete and detach the
customer registration card:
HHand the system user this part
for safe-keeping.
HRetain the heating engineer part.
2. File all parts lists, operating and
service instructions in the folder
and hand this over to the system
user.

9. Checking diaphragm expansion vessel and system pressure
Observe the diaphragm expansion vessel manufacturer s instructions.
Carry out this test on a cold system.
1. Drain the system or close the cap
valve on the diaphragm expansion
vessel and reduce the pressure
until the pressure gauge
indicatesĂ"0".
2. If the inlet pressure of the
diaphragm expansion vessel is
lower than the static system
pressure, top up with enough
nitrogen to raise the inlet pressure
higher than the static system
pressure (0.1 to 0.2Ăbar).
The static pressure corresponds to
the static height.
3. Top up the heating system with
water, until the filling pressure of a
cool system is higher (0.1 to
0.2Ăbar) than the inlet pressure of
the diaphragm expansion vessel.
Permiss. operating pressure: Ăbar.
10. Checking the tight fit of thermal insulation and cable

11. Checking mixer for easy operation and leaks
1. Remove the motorised lever from
the mixer handle, and check the
mixer for ease of movement.
2. Check the mixer for leaks.
Replace the OĆrings if the mixer
leaks.
3. Snap the motorised lever into
place.
12. Checking the draught stabiliser (if installed)
Release the latch on the control disc.
The control disc must swing freely
during burner operation.
13. Burner settings
Burners up to 63ĂkW Burner service instructions
Burners from 80ĂkW
Adjust the max. burner oil or gas
throughput so that the stated
maximum rated boiler output will
not be exceeded.
Note that, for multi-stage or
modulating burners, the flue gas
system must be suitable for the low
flue gas temperatures which may
arise during partial load operation.
Select the lowest partial load stage,
also taking the respective flue gas
system design into consideration.
Two stage
The following minimum output is
required for the base load stage to
protect the system against dew point
