Warranty, guarantee and liability

General

1.3

Warranty, guarantee and liability

Requirements

We  can  only  accept  liability  for  the  function  of  our
products  if  they  are  correctly  installed  and  operated.
This  is  only  possible  if  the  conditions  below  are
complied with.

Maximum of 2,000 hours at full load per year 

The boiler described in this user manual may only be
used for heating and producing hot water, with no more
than 2,000 full-load hours annually.

Installation in a dry room 

For set-up, a dry room is required. In particular, only
condensation dryers may be used as clothes dryers in
the same room.

Observe local building and fire safety regulations

Local  building  and  fire  safety  regulations  must  be
observed.

Suitable fuel

The  boiler  is  suitable  for  use  with  wood  pellets
according to EN ISO 17225-2:2014, quality class A1,
ENplus-A1.  Operation  with  unsuitable  fuels,  in
particular those containing halogens (chlorine) or high-
slag pellets such as from grain waste, is not permitted.

Ensure supply air is free from aggressive
substances

The  air  supplied  to  the  boiler  must  be  free  from
aggressive substances  such as chlorine and  fluorine
from solvents, cleaning agents, adhesives and propel-
lants,  or  ammonia  from  cleaning  agents,  to  prevent
corrosion of the boiler and chimney.

Permissible water hardness

Water  is  the  intended  heat-transfer  medium.  For
special anti-frost requirements, up to 30% glycol may
be added. Softened water is required for the initial fill-
up of the heating system and for refilling after repairs.
Addition  of  hard  water  should  be  minimised  to  limit
limescale build-up in the boiler.

In order to protect the boiler from calcification, the
water  hardness  of  the  heating  water  must  be

taken into account. Observe the indications outlined in
ÖNORM H 5195-1. Details can be found in chapter 

7.3

"Water hardness"

.

pH value between 8 and 9 

The pH value of water used to fill the heating system
must be between 8 and 9. 

Use a sufficient number of shut-off valves

Set  enough  shut-off  valves  to  avoid  bleeding  large
amounts  of  water  during  repairs.  Any  leaks  in  the
system must be repaired at once.

Provide a sufficiently large expansion tank or a
pressure maintaining device

To prevent air from being drawn in while the system is
cooling, the heating system professional must provide
a  sufficiently  large  expansion  tank  or  a  pressure
maintaining device.
Open expansion tanks must not be used.

Sufficient power 

Continuous  operation  with  heat  consumption  below
the  minimum  specified  on  the  type  plate  is  only
permitted with a buffer storage tank of sufficient size.

Expanding the control system 

Only  components  provided  by  us  may  be  used  for
expanding  the  control  system,  unless  these  are
generally available standard devices, such as thermo-
stats.

Regularly perform cleaning and maintenance

Cleaning and maintaining the product is essential. The
required steps and intervals are either contained in this
documentation or included as a separate document. 

Repairs 

Repairs are only permitted using spare parts provided
by us. The only exceptions are common standardised
parts such as electrical fuses or fastening materials, as
long as they possess the required features and do not
restrict the functionality of the system. 

Proper installation 

The installing contractor is liable for proper installation
according to the corresponding installation instructions
and the relevant rules and safety regulations. If you as
customer  have installed  the  heating system partly or
entirely  without  relevant  training  and  in  particular
without up-to-date practical experience, without having
the installation checked by a trained and responsible
expert, we exclude defects in our delivery and conse-
quential  damages  resulting  from  this  cause  from  our
warranty, guarantee and liability.
