3 Notes for operating a heating system
Carrying out modifications to the system and changing or disabling safety equipment
is prohibited.
Always comply with all fire, building and electrical regulations when installing or
operating the system, in addition to following the operating instructions and mandatory
regulations that apply in the country in which the tank is operated.
3.1 Installation site
Requirements for the load bearing substrate:
▪ Flat, clean and dry
▪ Non-combustible and with sufficient load-bearing capacity
Conditions at the installation site:
▪ Frost-free
▪ Sufficiently well lit
▪ Free of explosive atmospheres such as flammable substances, hydrogen halides,
cleaning agents and consumables
▪ Installation at altitude higher than 2000 metres above sea level only after
consultation with the manufacturer
▪ The system must be protected against gnawing and nesting by animals (such as
rodents)
▪ No flammable materials in proximity to the system
3.2 Domestic hot water
Unless contrary to other national regulations, the latest versions of the following
standards and guidelines apply:
Austria:
Germany:
ÖNORM H 5195
VDI 2035
Switzerland:
Italy:
SWKI BT 102-01
UNI 8065
Observe the standards and also follow the recommendations below:
rAim for a pH value of between 8.2 and 10.0. If the central heating water comes into
contact with aluminium, the pH value must be between 8.2 and 9.0
rUse prepared water which complies with the standards cited above for filling and
make-up water
rAvoid leaks and use a closed heating system to maintain water quality during
operation
rWhen filling with make-up water, always bleed the filling hose before connecting, in
order to prevent air from entering the system
rThe heating water must be clear and free from substances that lead to sediments.
rWith regard to corrosion protection, the use of fully demineralised filling and make-
up water with an electrical conductivity of up to 100 µS/cm is recommended in
accordance with EN 14868

3 | Notes for operating a heating system
16 B1650222_en | Operating instructions PE1e Pellet
Advantages of low-salt or fully demineralised water:
▪ Complies with the applicable standards
▪ Less of a drop in output due to reduced limescale build-up
▪ Less corrosion due to fewer aggressive substances
▪ Long-term cost savings thanks to improved energy efficiency
Filling and make-up water as well as heating water in accordance with VDI 2035:

> 200 to ≤ 600 ≤ 1.5 (8.4) < 0.05 (0.3)
> 600 < 0.05 (0.3)
1. For calculating the specific system volume, the smallest individual heating capacity is to be used for systems with several heat generators.
2. In systems with several heat generators with different specific water contents, the smallest specific water content is decisive in each case.
Additional requirements for Switzerland
The filling and make-up water must be demineralised (fully purified)
▪ The water must not contain any ingredients that could settle and accumulate in the system
▪ This makes the water non-electroconductive, which prevents corrosion
▪ It also removes all the neutral salts such as chloride, sulphate and nitrate which can
weaken corrosive materials in certain conditions
If some of the system water is lost, e.g. during repairs, the make-up water must also be
demineralised. It is not enough to soften the water. The heating system must be professionally
cleaned and rinsed before filling the units.
Inspection:
▪ After eight weeks, the pH value of the water must be between 8.2 and 10.0. If the central
heating water comes into contact with aluminium, the pH value must be between 8.0 and
8.5
▪ Yearly. Values must be recorded by the owner

B1650222_en | Operating instructions PE1e Pellet 17
3.3 Pressure maintenance systems
Pressure maintenance systems in hot-water heating systems keep the required
pressure 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
expansion 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
into the heating water.
Pump-controlled pressure maintenance
A pump-controlled pressure maintenance unit essentially consists of a pressure-
maintenance 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 expansion 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.
3.4 Storage tank
NOTICE
In principle it is not necessary to use a storage tank for the system to run smoothly.
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 Fröling.
Additional requirements for Switzerland in accordance with LRV Appendix 3, section 523
Automatic boilers for wood pellets with a rated thermal output of more than 70 kW
must be equipped with a heat accumulator of a volume of at least 25 litres per kW
rated thermal output. These dimensioning specifications apply up to 500 kW nominal
heat output.

3 | Notes for operating a heating system
18 B1650222_en | Operating instructions PE1e Pellet
3.5 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. 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.
NOTICE!Please see the technical data contained in the assembly instructions
for further information about standards and regulations as well as the flue gas
temperatures when clean and the other flue gas values!
3.6 Condensate drainage
The condensate must be continuously drained into the waste water system in
accordance with local regulations for heating systems with condensing boiler
technology.
In respect of the condensate drainage, ensure:
▪ Line of raw material resistant to condensate
▪ Diameter at least 50 mm
▪ Lengths of line as short as possible
▪ Fall gradient at least 3°
▪ Frost-free
▪ Easily accessible for disassembly and cleaning
▪ Inspection at regular intervals
NOTICE!The condensate connection may not be changed or closed.
NOTICE!If the pipework to the drain cannot be installed in a correct fashion, the
use of waste water pumping system is recommended. Suitable systems are
available on request from Fröling GesmbH.
