2.4.2 Installation and approval of the heating system
The boiler should be operated in a closed heating system. The following standards
govern the installation:
ÖNORM / DIN EN 12828 Heating Systems in Buildings
NOTICE! Each heating system must be officially approved.
The appropriate supervisory authority (inspection agency) must always be informed
when installing or modifying a heating system, and authorisation must be obtained
from the building authorities:
Austria: Inform the civic/municipal building authorities.
Germany: Notify an approved chimney sweep and the building authorities.
2.4.3 General information for installation room (boiler room)
Boiler room characteristics
▪ There must not be a potentially explosive atmosphere in the boiler room as the
boiler is not suitable for use in potentially explosive environments.
▪ The boiler room must be frost-free.
▪ The boiler does not provide any light, so the customer must provide sufficient light‐
ing in the boiler room in accordance with national workplace design regulations.
▪ When using the boiler over 2000 metres above sea level you should consult the
manufacturer.
▪ Danger of fire due to flammable materials.
No flammable materials should be stored near the boiler. Flammable objects (e.g.
clothing) must not be put on the boiler to dry.
▪ Damage due to impurities in combustion air.
Do not use any solvents or cleaning agents containing chlorine in the room where
the boiler is installed.
▪ Keep the air suction opening of the boiler free from dust.
Ventilation of the boiler room
Ventilation air for the boiler room should be taken from and expelled directly outside,
and the openings and air ducts should be designed to prevent weather conditions (foli‐
age, snowdrifts, etc.) from obstructing the air flow.

2.4.5 Notes for using pressure maintenance systems
Pressure maintenance systems in hot-water heating systems keep the required pres‐
sure within predefined limits and balance out volume variations caused by changes in
the hot-water temperature. Two main systems are used:
Compressor-controlled pressure maintenance
In compressor-controlled pressure maintenance units, a variable air cushion in the ex‐
pansion tank is responsible for volume compensation and pressure maintenance. If
the pressure is too low, the compressor pumps air into the tank. If the pressure is too
high, air is released by means of a solenoid valve. The systems are built solely with
closed-diaphragm expansion tanks to prevent the damaging introduction of oxygen in‐
to the domestic hot water.
Pump-controlled pressure maintenance
A pump-controlled pressure maintenance unit essentially consists of a pressure-main‐
tenance pump, relief valve and an unpressurised receiving tank. The valve releases
hot water into the receiving tank if the pressure is too high. If the pressure drops below
a preset value, the pump draws water from the receiving tank and feeds it back into
the heating system. Pump-controlled pressure maintenance systems with open expan‐
sion tanks (e.g. without a diaphragm) introduce ambient oxygen via the surface of the
water, exposing the connected system components to the risk of corrosion. These
systems offer no oxygen removal for the purposes of corrosion control as required by
VDI 2035 and in the interests of corrosion protection should not be used.
2.4.6 Return lift
If the hot water return is below the minimum return temperature, some of the hot water
outfeed will be mixed in.
CAUTION
Risk of dropping below dew point/condensation formation if operated without re‐
turn temperature control.
Condensation water forms an aggressive condensate when combined with com‐
bustion residue, leading to damage to the boiler.
Take the following precautions:
❒ Regulations stipulate the use of a return temperature control.
➥The minimum return temperature is 60 °C. We recommend fitting some
sort of control device (e.g. thermometer).

2.4.7 Combination with storage tank
Observe the regional regulations for using a storage tank!
Certain subsidy guidelines prescribe compulsory requirements for the installation of
storage tanks. Up-to-date information about individual subsidy guidelines can be found
at www.froeling.com.
Channelling the heat generated by the Firewood boiler to a storage tank, can bring
major advantages, including:
❒better utilisation of fuel
❒ more user-friendly operation in terms of reloading intervals
❒ maximum independence from instantaneous heating requirements
❒ minimal dirt in boiler and flue gas system
As the boiler’s minimum continuous heat output is 30% above the nominal heat out‐
put, we as the boiler manufacturer are obliged under EN 303-5:2012, Section 4.4.6 to
advise that the Firewood boiler S3 Turbo must always be connected to a storage tank
with adequate storage capacity.
Certain countries have recommended storage capacities; these are listed below. The
specified values apply when the nominal heat output of the boiler corresponds to the
heating requirements of the building and a maximum of 50% of the nominal heat out‐
put can be dissipated to the building being heated under partial load conditions.
The storage tank capacity can be calculated according to EN 303-5:2012 using the fol‐
lowing formula:
VSp = 15TB x QN (1 - 0.3 x QH/Qmin)
VSp

QH
Qmin
Storage tank capacity in [l]
Nominal heat output of boiler in [kW]
Burn-off period of boiler in [h]1)
Heating load of building in [kW]
Minimum heat output of boiler in [kW] 2)
1.Sample combustion times for various fuels are provided in the technical data
2.The boiler’s minimum output is the lowest value of the output range in the technical data. If there is no minimum heat output specified, use
the nominal heat output (Qmin = QN)
NOTICE! EN 303-5:2012 stipulates that the storage tank capacity is at least 300l!
According to the relevant Austrian laws governing energy technology, which are based
on Art. 15a B-VG "Agreement on protective measures for small furnaces" (2012):
No storage tank is required on manually fed biomass boilers that have been positively
tested at both nominal load and partial load (below 50% of nominal load) to ensure
they adhere to the emissions limits specified in that agreement.

2.4.8 Chimney connection/chimney system
EN 303-5 specifies that the entire flue gas system must be designed to prevent, wher‐
ever possible, damage caused by seepage, insufficient feed pressure and condensa‐
tion. Please note in this respect that flue gas temperatures lower than 160K above
room temperature can occur in the permitted operating range of the boiler.
The flue gas temperatures (for clean systems) and additional flue gas values can be
found in the table below.
The connection between the boiler and the chimney system should be as short as
possible. The upward angle of the connection should not exceed 30° - 45°. Insulate
the connection. The entire flue gas system - chimney and connection - should be cal‐
culated in accordance with EN 13384-1.
Local regulations and other statutory regulations also apply.
NOTICE! The chimney must be authorised by a smoke trap sweeper or chimney
sweep.
Draught limiter
The installation of a draught limiter is recommended.
NOTICE! Install the draught limiter directly under the mouth of the flue line, as the
pressure is constantly low at this point.
