Pyrotec Installation & Operating
Operation
Commissioning
Initial startup
Only a Viessmann or another trained specialist may put
a newly installed system into operation for the first time.
Before the system is commissioned, the system must be
filled with water, and the fuel for the commissioning and
the installation itself must be inspected.
Note: It is mandatory to complete the Viessmann biomass
project pre-commissioning form.
Be absolutely sure to follow the instructions. No
warranties may be claimed for damages in cases of initial
start-ups carried out improperly at one’s own initiative.
First check:
- Is there enough water in the heating system?
- Has the heating system been bled of air?
- Are the slide valves open for the heating-system’s
supply and return flow?
- Can enough fresh air get into the heating room?
- Is the ash bin empty?
- Are the doors and lids on the boiler closed leak-tight?
- For safety, keep firing and ash pit doors tightly closed.
Filling the heating system
The first filling is usually performed with chemically
untreated filtered water free of any suspended solids.
Ensure that the air is carefully bled out while filling the
boiler. Use appropriate water treatment specific to the
local water conditions.
Note: The system fill pressure when the system is cold
should be approximately 1.5 psi (0.1 bar) greater
than the supply pressure of the closed expansion tank.
Commissioning and hand over
A qualified person from the owner’s side must be present
for the commissioning and hand over.
The heat dissipation from the boiler plant has to be
assured by the operating organization or by the heating
contractor.
The heating contractor must confirm that the installation
has passed inspection and signed off.
Compliance with these Installation Instructions and the
Operating Instructions will ensure a safe and convenient
heating with wood.
These Installation and Operating Instructions should be
kept near the system on a permanent basis.
CAUTION
Ensure that a Viessmann or another trained specialist
is present for the boiler start-up and that it is done in
a timely manner.
The warranty becomes null and void if this procedure
is not followed.

IMPORTANT
Fuel for the commissioning
For the commissioning, sufficient dry fuel (max. W 20%)
should be stored for approx. 10-24 full operating hours:
PYROTEC 390 approx. 5100 lb.
PYROTEC 530 approx. 6600 lb.
PYROTEC 720 approx. 8800 lb.
PYROTEC 950 approx. 11660 lb.
PYROTEC 1250 approx. 14960 lb.
Since the boiler plant will be cold, and residual moisture
will be drawn from the refractory concrete during the
initial operation, the material to be burned for the initial
operation has to be at least air dry. For the first three hours,
the heating-up process should be carried out at low output.
To ensure that the silo extraction system is functioning
properly, only place a minimal amount of fuel in the silo
in case there is a problem. This enables the extraction
system to be cleaned out quickly and the problem to be
identified and corrected.
