1.2 Design Information
It is forbidden to carry out modifications to the boiler or to change or
deactivate safety equipment.
Always comply with all fire, building, and electrical regulations when
installing or operating the boiler system, in addition to following the
operating instructions and mandatory regulations that apply in the
country in which the boiler is operated.
1.2.1 Approval and obligation to report
NOTICE
Each heating system must be officially authorised.
The appropriate supervisory authority (inspection agency) must always be
informed when installing or modifying a heating system, and authorisation
obtained from the building authorities.
Austria: Inform the civic/municipal building authorities.
Germany: Register with an approved chimney sweep/the building
authorities.
1.2.2 Requirements for central heating water
The requirements pertaining to the water used to fill the boiler are
based on the following standards and guidelines:
Applicable standards and guidelines:
Austria: ÖNORM H 5195-1
Germany: VDI 2035
Switzerland: SWKI 97-1
There are no other special requirements for central heating water.
Note on filling with make-up water: bleed the filling hose before
connecting to prevent air from getting into the system.

1.2.3 Ventilation of boiler room
The openings for the supply air and the exhaust air should be arranged
as close to opposite each other as possible to achieve a good thermal
draught effect.
The supply air must be drawn in directly from outside. Exhaust air
must be discharged directly outside.
Unless otherwise stipulated by the building regulations applicable to the
room where the boiler is to be installed, the following standards shall
apply:
Applicable standard:
- ÖNORM H 5170
1.2.4 Installing the heating system / Standards
The following standards govern the installation of heating systems:
Applicable standards:
ÖNORM / DIN EN 12828 Heating Systems in Buildings
The following prior standards still apply:
Austria: - Closed systems as per ÖNORM B 8131
- Open systems as per ÖNORM B 8130
Germany: - Closed systems as per DIN 4751 Part 2
- Open systems as per DIN 4751 Part 1
Return feed lift
If the hot water return feed is below the minimum return feed
temperature, some of the hot water outfeed will be mixed in.
CAUTION
Risk of dropping below dew point/condensation formation if operated
without return feed lift.
Condensation water forms an aggressive condensate when combined
with combustion residue, leading to damage to the boiler.
Regulations stipulate the use of a return feed lift.
The minimum return feed temperature is 55 °C. We recommend fitting
some kind of control device (e.g. thermometer).

Combination with storage tank
In accordance with the relevant Austrian laws governing energy
technology, which are based on Art. 15a B-VG “Agreement on protective
measures for small furnaces” dated November 1994, no buffer storage
tank is required on manually fed biomass boilers that have been
positively tested at both rated load and partial load (below 50% of rated
load) to ensure they adhere to the emissions limits specified in that
agreement.
Germany has specified its own emissions limits in the “First Ordinance
on Implementation of the Federal Emissions Control Act (1st BImSchV)”.
Provided that commissioning is carried out by our customer services or
an authorised partner company, it can be assumed that these
requirements will also be complied with under partial load conditions in
accordance with § 6 (3) of the 1st BImSchV. This means that the
complete range of firewood boilers can be used in Germany without
requiring a mandatory buffer storage tank.
Combining the system with a buffer storage tank does however offer
significant advantages when using a firewood boiler, such as better
utilisation of the fuel, more user-friendly operation in terms of reloading
intervals (which means the greatest possible independence from
instantaneous heating requirements), and less soiling of the boiler and
flue gas system. In addition to the above, as the manufacturer of the
boiler we have to advise on how the heat generated can be dissipated.
This is because compliance with the emissions limits and minimum level
of efficiency at a minimum heat output of 30% of the rated heat output,
as specified in Section 4.2.5 or EN 303-5, has not been demonstrated
for all variants of the system.
The opportunities for heat dissipation are particularly good if the central
heating system has sufficient capacity for heat uptake, for example
through underfloor heating circuits with a suitable water volume or hot
water tanks with appropriate reserve capacity. It should also be noted
that the integral thermal discharge safety device ensures that the boiler
will operate safely even if it is overfilled or has too little load reduction.
If, however, the amount of heat that can be temporarily dissipated
within the building being heated is limited, then additional heat
dissipation can be provided by a buffer storage tank.
The recommend storage volume for each boiler is given in the technical
specifications. The specified value applies under the following
conditions: the rated heat output of the boiler corresponds to the
heating requirements of the building and a maximum of 50% of the
rated heat output can be dissipated to the building being heated under
partial load conditions.
Certain subsidy guidelines also prescribe compulsory
requirements for the installation of buffer storage tanks:
Some guidelines relate to minimum storage volume in accordance with
EN 303-5, as given in the technical specifications.
... In Austria: some subsidy guidelines of Austrian federal states
(e.g. those of the Vorarlberg state government)
... In Switzerland: The “Quality Seal for Wood Burning Systems”
scheme from Holzenergie Schweiz

Standards, Design, Assembly

Other guidelines are based on tank size, e.g.
... In Austria: Specific subsidy guidelines for Austrian states (e.g.
Styrian state government guidelines: buffer storage
tanks of at least 800 L)
... In Germany: “BAFA Förderung” guidelines on measures to promote a
better use of renewable energies of the Federal Office
of Economics and Export Control (BAFA): buffer storage
tanks of at least 55 L/kW
Up to date information relating to specific subsidy guidelines for various
regions can be found on our website at www.froeling.com.
1.2.5 Chimney connection/chimney system
EN 303-5 specifies that the entire flue gas system must be designed to
prevent, wherever possible, damage caused by seepage, insufficient
feed pressure and condensation.
It should be noted here that flue gas temperatures of less than 160 K
above room temperature can occur within the permitted operating range
of the boiler.
The flue gas temperatures (for clean systems) and additional flue gas
values can be found in the technical specification sheets.
See “Boiler data relating to design of the flue gas system”
Connect to the chimney via the shortest path, preferably with a vertical
gradient of less than 30–45°. Insulate the connecting piece.
The entire flue gas system (chimney and connection) must be calculated
as per ÖNORM/DIN EN 13384-1 or prior standards
ÖNORM M 7515/DIN 4705-1.
Local regulations and other statutory regulations also apply.
The chimney must be authorised by a smoke trap sweeper or
chimney sweep.
Draught limiter
We recommend that a draught limiter is fitted (1)
Install the draught limiter directly under the mouth of the flue line,
as the pressure is lower at this location.

and the largest boilers. The boiler manufacturer must ensure that all boilers, including those that have not been tested in a
range, whose values have been determined depending on rated heat output by interpolation, fulfil the requirements of the
norm.
3) Values for the type S4 Turbo 50 are interpolated between the test protocol 07-UWC/Wels-EX-094/3 and 08-UW/Wels-EX-074.
