General information
Safety instructions
Please follow these safety instructions closely to prevent accidents and
material losses.
If you smell gas
HDo not smoke! Do not use naked
flames or cause sparks (e.g. by
switching lights or electrical
appliances ON or OFF)
HOpen windows and doors
HClose gas shut−off valve
HNotify your heating engineer/
installation contractor from outside
the building
HObserve the safety regulations of
your gas supplier (see gas meter)
and of your local heating
contractor (see commissioning/
training report).
In an emergency
HImmediately switch OFF emergency
stop switch (outside boiler room)
(except if you smell gas).
HClose the shut−off valves of the
main fuel lines.
HFor fire, use an appropriate fire
extinguisher.
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 equipment/ heating
system, isolate its 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
main gas shut−off valve and safeguard
against unauthorised reopening.
Installation of additional components
Installation of additional components
which have not been tested together
with the boiler can adversely affect the
boiler function.
Our warranty does not cover and we
accept no liability for damage caused
by the installation of such components.
Boiler room conditions
HDo not use where air is polluted
with halogenated hydrocarbons
(e.g. as in aerosols, paints,
solvents and cleaning agents)
HPrevent very dusty conditions
HAvoid rooms with permanently
high levels of humidity
HRoom should be frost protected
HEnsure good ventilation, and never
close any vents.
Work on gas equipment
This must only be carried out by an
approved contractor.
Please observe all commissioning
work for gas installations specified
according to TRGI or TRF, or local
regulations.
Repair work
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
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.

Initial start−up, inspection and maintenance
Further details regarding the individual steps
Maintenance instructions
We recommend that your boiler system is maintained regularly by a heating
specialist to ensure fault−free, energy−conscious and environmentally safe
operation of your heating system.
Your boiler must be cleaned at regular intervals, otherwise the flue gas
temperature rises with increasing contamination, which leads to higher
energy losses.
We recommend the use of a flue gas thermometer.
Monitoring the flue gas temperature highlights incorrect burner settings and
the level of boiler contamination.
Excessive flue gas temperatures through boiler contamination or incorrect
burner setting reduces the system efficiency. Where necessary, clean the
boiler or adjust the burner settings.
Adjusting the pressure regulator and pressure limiter
1. Adjust the pressure limiter
response pressure a little higher
than that of the pressure regulator.
2. Secure the protective cap again on
the pressure limiter to prevent any
unauthorised adjustment at a later
time.
3. During commissioning, adjust the
pressure regulator to the required
operating pressure.
Do not alter this setting later.
Adjust the pressure regulator for
stage 1 a little higher and a little
lower for stage 2.
Note
Each pressure regulator is
equipped with a setting screw
each for adjusting the switching
point (e.g. 0.45bar) and for
selecting the switching differential
(e.g. 0.02bar), i.e., the pressure
regulator starts the burner at
0.43bar and switches it OFF at
0.45bar.

Initial start−up, inspection and maintenance
Further details regarding the individual steps (cont.)
According to the [German] Health & Safety at Work Act, steam boilers with a
safety pressure in excess of 0.5bar must be monitored. In accordance with
the conformity assessment diagram no.5 of the EU Pressure Equipment
Directive, these boilers must be categorised as classIII. Prior to
commissioning, this system must be tested by an authorised body (e.g. TÜV).
System start−up
Observe the information
provided by the suppliers of
burner and accessories.
1. Check that turbulators are fully
pushed into hot gas flues
(against their end stop)
(open boiler door).
2. Check that the boiler room
ventilation is unobstructed.
3. Check the function of the water
treatment system.
4. Fill the steam boiler with water
higher than the NW indicator.
Note
Only operate steam boilers with
suitable water; see also water
quality requirements on page26.
5. Check all fitted components, such
as pipework, valves, regulators,
pumps etc. for function and
leaks.
6. Check the fuel oil level or the gas
supply pressure.
7. Open the flue gas damper (where
appropriate).
8. Check whether cleaning aperture
on the flue outlet is closed.
9. Open the shut−off valves in oil
supply pipes (at the oil tank and
filter) or open the gas shut−off
valve, whichever is applicable.
10. Switch ON the mains electrical
isolator, the switch for the feed
water pump and the burner
ON/OFF switch, in that order.
Burner manufacturer’s
operating instructions
11. Start the boiler with a low output
(burner stage1 or partial load)
and slowly ramp up to the
required operating pressure.
12. Slowly open the steam valve
after the required operating
pressure has been reached.
13. Only enable the full burner load
at that point.
14. While the system heats up, check
the correct function of all control
and safety equipment.
15. Observe the pressure and
temperature test equipment.
16. Check the fittings for leaks and
tighten, if necessary.
17. Check the boiler door and
clean−out cover after approx.
50hours and retighten all
screws.
Note
We would recommend that you
operate the boiler constantly at the
required operating pressure.
The boiler may still be operated at
pressure, even if no heat demand
occurs for a longer period of time.
In systems comprising several
boilers, of which one is constantly
used as standby boiler, only change
the operation over in longer
intervals, e.g. during the annual
inspection of the total system.

Further details regarding the individual steps (cont.)
System shutdown
¨Safety instruction
Only open the water and steam
connections and the inspection ports
after the boiler has been completely
depressurised.
1. Close the shut−off valves in the oil
supply pipes (at the oil tank and
filter) or the gas shut−off valve,
whichever is applicable.
2. Switch OFF the burner and the
feed water pump. Pull the
connecting plug from the burner.
3. Isolate the system from the mains
power supply.
4. Close all valves.
Information regarding system shutdowns
If you do not require to use your
boiler system temporarily, maintain
the boiler water temperature by
means of the thermostat (standby) at
95ºC, to prevent corrosion through
ingress of oxygen into the boiler
water.
If you want to shut down your
heating system for longer periods of
time (several months), shut it down
completely.
HBefore taking the system out of use
for longer periods, we recommend
you take certain measures, e.g.
protecting the system against frost
or preserving the heating surfaces.
HThoroughly clean the surfaces on
the flue gas side to preserve the
heating surfaces. Then conserve
these surfaces with a preserving oil
mixed with graphite.
HFor the protection of the water
side, we recommend you flood the
boiler with degassed, oxygen−free
and treated water with low salt
content and added oxygen binders
(e.g. sodium sulphite).
Then close the steam shut−off
valve.
Check the concentration of the
oxygen binder at least every month
and replenish, if necessary. When
doing this, ensure that the binder is
well−mixed with water inside the
boiler.
HAnother option is that of dry
preservation, which is
recommended for shutdown
periods longer than 4weeks.
HWhen there is a risk of frost, drain
the boiler and the heating system
via the drain plug.
Open the shut−off and regulating
valves as well as the air vents.
