3.4.1 Connection line to the chimney
Requirements got the connection line:
▪ This should be as short as possible and follow an upward incline to the chimney (30 -
45° (recommended)
▪ Leak-tight against overpressure
▪ Thermal insulation recommended
Distance from flammable components:
▪ 100 mm if at least 20 mm thermal insulation is installed
▪ 375 mm if no thermal insulation is present
Recommendation: three times the diameter of the connection line
3.4.2 Measuring port
For emissions measurement on the system, a suitable measuring port must be installed in the connection line between the boiler and chimney system.
D
2 x D
M
D
Upstream of the measuring port (M) there should be a straight run-in section with a length about twice the diameter (D) of the connection line. Downstream of the measuring port
(M) there should be a straight run-out section with a length about the diameter (D) of the connection line. The measuring port must remain closed whenever the system is in operation.
The diameter of the measuring probe used by Froling customer service is 14 mm. To avoid measuring errors due to the ingress of false air, the diameter of the measuring port must not exceed 21 mm.
3.4.3 Draught limiter
We generally recommend the installation of a draught limiter. A draught limiter must be installed if the maximum permissible feed pressure as given in the boiler data for planning the flue gas system is exceeded.
NOTICE! Install the draught limiter directly under the mouth of the flue line, as the pressure is constantly low at this point.
3.4.4 Explosion flap
TRVB H 118 (only Austria) stipulates that an explosion flap must be installed in the connection line to the chimney, directly next to the boiler. It should be situated in such a way that is poses no risk to persons!

Boiler in room air-dependent operation
Air extraction system (such as centralised dust extraction system, room ventilation)
Under-pressure monitoring system
Combustion air supply from outside
3.5.1 Combustion air supply at the installation room
The system is operated in open flue mode, i.e. the combustion air required to operate the boiler is drawn from the installation room.
Requirements:
▪ Opening to the atmosphere
– Weather conditions must not affect the air flow in any way (e.g. snow and foliage)
– Cross-section area free of obstructions such as cover gratings and slats
▪ Air supply lines
– For air supply lines longer than 2 metres and where mechanical means are used to feed combustion air, the flow rate must be calculated (maximum flow rate = 1 m/ s)
Note on standards
ÖNORM H 5170 - Construction and fire protection requirements
TRVB H118 - Technical directives on fire protection/prevention
3.5.2 Simultaneous operation with other air-drawing systems
Where the boiler is operated in room air-dependent mode with simultaneous operation of other air-drawing systems (such as room ventilation), safety devices are necessary:
▪ Air pressure monitor
▪ Flue gas thermostat
▪ Window-tilting drive system, window-tilting switch
NOTICE! Clarify the safety devices with appropriate flue sweep / chimney sweep
Recommendation for room ventilation:
Use “intrinsically-safe” room ventilation systems with F classification
12 M0931621_en | Installation instructions Pellet boiler P4 Pellet
Design Information | 3
As a basic rule:
▪ Room under-pressure max. 8 Pa
▪ Air-drawing systems must not exceed the room under-pressure value
– If the room under-pressure value is exceeded, safety equipment (under-pressure monitoring system) is necessary
In Germany, the following additional requirement must be observed:
DiBt requires that an approved under-pressure monitoring system (such as air pressure monitor P4) which monitor the maximum under-pressure to 4 Pa must be installed in the installation room.
In addition, at least one of the following three requirements must be met:
(Source: Section 4 MFeuV 2007 / 2010)
▪ Dimension the cross-section of the combustion air opening so that when the boiler is in operation the maximum under-pressure is not exceeded (simultaneous operation)
▪ Use safety equipment that prevents simultaneous operation (alternate operation)
▪ Monitor the flue gas outlet using safety devices (such as a flue gas thermostat)
Simultaneous operation
An approved safety system (such as an air pressure monitor) ensures that during simultaneous operation of the boiler and the air-drawing appliance the pressure conditions are maintained. In the event of a fault, the safety system will switch off one of the air-drawing systems.
Alternating operation
An approved safety system (such as a flue gas thermostat) ensures (e.g. by switching off the power supply) that the boiler cannot be operated simultaneously with the air-drawing appliance.

} 7] r Connect the supply air line leak-tight to the connection on the boiler
Ä Refer to the dimensions of the supply air line connection on the boiler in the
Technical Data
When dimensioning pipe bends in the supply air line, ensure that:
The ratio of the radius of curvature (r) to pipe diameter (d) is greater than 1 r:d ≥ 1
For example:
- supply air line diameter = 160 mm
- minimum radius of pipe bends = 160 mm
▪ The supply air line should be as straight as possible and take the shortest path
▪ Keep the number of pipe bends to a minimum
▪ Max. resistance of the supply air line: 20 Pa
3.6.3 Condensation
NOTICE! The greater the difference between the temperature of the outside air being drawn in and the room temperature, the greater the risk of condensation
In Germany, the following additional requirement must be observed: The lines must be installed with an incline making sure that any condensation water can drain away and the outside air can be drawn in without allowing water or animals from entering the building.
To avoid condensation: r Jacket the entire supply air line with suitable thermal insulation

3.7 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: r Aim 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 8.0 and 8.5
r Use prepared water which complies with the standards cited above for filling and make-up water r Avoid leaks and use a closed heating system to maintain water quality during operation r When filling with make-up water, always bleed the filling hose before connecting, in order to prevent air from entering the system
Advantages of prepared 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

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
3.8 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 hotwater 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 closeddiaphragm 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 pressuremaintenance 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 .

3.9 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 Froling.
3.10 Boiler ventilation
r Fit the automatic ventilating valve at the highest point on the boiler or at the ventilation connection (if present).
Ä This ensures that air in the boiler is constantly expelled, thus preventing malfunctions caused by air in the boiler r Check that the boiler ventilation is working properly
Ä After installation and periodically according to manufacturer’s instructions
Tip: r Fit a vertical pipe as a calming section in front of the automatic ventilating valve in such a way that the ventilating valve is positioned above the water level in the boiler
Recommendation: r Fit a microbubble separator in the pipes to the boiler
Ä Follow the manufacturer's instructions!

R > 30cm
R
R
Please note the following with regard to the hose lines used in Froling vacuum discharge systems:
▪ Do not kink the hose lines! Minimum bending radius = 30cm
▪ Lay the hose lines as straight as possible! Sagging lines can lead to so-called
“pockets”, which may cause problems with the pellet feed.
▪ Lay the hose lines in short sections away from walking areas.
▪ Hose lines are not UV-proof. Therefore: Do not lay the hose lines outdoors.
▪ Hose lines are suitable for temperatures up to 60°C. Therefore: Hose lines must not come into contact with flue gas pipes or uninsulated heating pipes.
▪ Hose lines must be earthed on both sides to ensure that no static charge builds up as a result of transporting the pellets.
▪ The suction hose to the boiler must be in a single section.
▪ The return-air line can be made up of several sections, but consistent potential equalisation must be established throughout the line.
▪ For systems starting at 48 kW, only suction hoses with PU inlets are recommended due to the increased load.
44 M0931621_en | Installation instructions Pellet boiler P4 Pellet
Assembly | 6
Potential equalisation
When connecting the hose lines to the individual connections, ensure there is consistent potential equalisation throughout the line.
r Expose approximately 3 cm of the earth wire at the end of the hose line
Ä TIP: Slit the insulation open along the wire with a knife r Bend the earth wire inwards in a loop
Ä This prevents the earth wire from being damaged by the pellet movement r Slide the hose clamp onto the hose line r Attach the hose line to the connector
Ä Ensure that contact is established between the earth wire and the connector
Ä TIP: If stiffness occurs when trying to attach the hoses to the connectors, pour a few drops of water onto the pipe (do not use grease).
r Secure the hose line with a hose clamp
6.4 Power connection and wiring
DANGER
When working on electrical components:
Risk of electrocution!
When work is carried out on electrical components: r Always have work carried out by a qualified electrician r Observe the applicable standards and regulations
