Important information for system operators
1.5 Start-up and maintenance
Please permit Windhager Customer Service or have one of our customer service Partners put your new boiler into
service. In this way, all functions of the new unit will be thoroughly checked; you will also benefit from the detailed
information provided by the system installer. Installation by a qualified technician as well as the maintenance
required by the guarantee limitations and undertaken by Windhager Customer Service or a customer service
partner will guarantee the optimal use and service life of your boiler system. This is the only way to assure the
benefits of this technologically advanced boiler and guarantee safe, environmentally friendly and energy-saving
system operation.
The following preconditions must be met before you order the initial start-up:
1.) Boiler installed correctly.
2.) System fully wired up electrically.
3.) System rinsed, filled and vented – heat consumption must be possible.
4.) Boiler connected to domestic water and filled.
5.) Sufficient quantity of fuel available (pellets, split logs, oil or gas).
6.) The customer must be present during start-up.
The initial start-up cannot be carried out if any of these points are neglected. The customer will be charged for
any unnecessary costs arising as a result.
Start-up and maintenance by Windhager Customer Service or a customer service partner are part of the gua-
rantee requirements of the enclosed “guarantee limitations”.
Note!
During the first few weeks after start-up, condensation can occur in the combustion chamber, ash
pan and on the heating surfaces. This has no effect on the function and service life of the boiler.
1.6 Functional test
EN 12828 and ÖNORM B8131 require that the function of the system and related safety equipment be checked
and certified yearly by a qualified technician (installer, heating system contractor).
At two-year intervals, the heating water condition must be checked (ÖNORM H 5195) by a heating expert (installer)
(see BioWIN assembly instructions – Heating water); this is to prevent corrosion and sediment accumulation in
the heating system and boiler. For systems using more than 1,500 litres of water (e.g., systems with accumulator
tanks), this inspection is required on an annual basis.
In the event of repair work requiring a change of water in the heating system, the heating water is to be checked
within 4 to 6 weeks after such work.
Corrosion and sediment resulting from improper heating water are not covered by the guarantee and warranty.
