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.

D.P.R. no. 412
NOTICE! Note on filling with make-up water: always bleed the filling hose before con‐
necting, in order to prevent air from entering the system.
Observe the standards and also follow the recommendations below:
❒Max. cumulative value for alkaline earth: 1.0 mmol/l or 100 mg/l (corresponds to
5.6 dH)
❒ Use softened water as the make-up water
❒ Avoid leaks and use a closed heating system to maintain water quality during op‐
eration
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 temperature control
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:
❒ We recommend using a return temperature control.
➥The minimum return temperature is 45 °C. We recommend fitting some
sort of control device (e.g. thermometer).

2.4.7 Use with storage tank
NOTICE
In principle it is not necessary to use a storage tank for the system to run smooth‐
ly. However, we recommend that you use the system with a storage tank, as this
ensures a continuous supply of fuel in the ideal output range of the boiler.
For the correct dimensions of the storage tank and the line insulation (in accordance
with ÖNORM M 7510 or guideline UZ37) please consult your installer or Froling.
⇨ See "Addresses" [page 29]
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.
NOTICE! TRVB H 118 (Austria only) stipulates that an explosion flap must be installed
in the connecting piece (flue pipe) directly next to the boiler. It should be situated in
such a way that is poses no risk to persons!
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.
