For the Installer
2.11 Installing the exhaust pipe
Comply with minimum clearanc
es in section 2.5!
a) Install the exhaust pipe upward to the flue (45° is the ideal angle). Maximum exhaust pipe length 3 m.
Information!
Any section of this exhaust line that only rises slightly (up to 30°) or is horizontal is not allowed to be
more than 1 m in length.
b) Avoid 90° bends, 45° bends are better
c) Make the flue connection at 45° if possible.
d) Do not push the exhaust pipe too far into the flue.
e) Do not seal the exhaust pipe completely into the flue. Connection with flexible exhaust pipe inlet into the flue.
The Induced draught fan can cause sound transmissions that create noise pollution.
f) The BioWIN is a low-pressure boiler and this means that the flue gas system needs to meet the „N1“ seal in-
tegrity requirement according to EN 1856-1 and EN1856-2. Please ensure a sufficient immersion depth when
fitting (e.g. when using Windhager stainless steel flue systems).
g) The entire exhaust line (particularly after 1 m length) should be insulated in order to prevent or minimise
condensation.
2.12 Fitting cleaning tools
1 ........... Cleaning brush
2 ........... Spatula
3 ........... Cleaning tool/cone removal tool

2.13 Installing the thermal process safeguard
(Not needed for all boiler models, only if the boiler has a thermal safety device.)
Connecting thermal process safeguard to thermal safety device
a) The thermal process safeguard and cleaning T-piece must still be accessible after installation.
b) Water must be seen to be draining out in order to check the function, therefore use a discharge funnel.
c) It must not be possible to block the connection manually.
Connection according to EN 303-5:
Fig. 55 Thermal safety device connection
Minimum connection pressure of the thermal safety device: 2 bar.
1 ........... Pressure reducing valve (only with CW connection of more than 6 bar)
2 ........... Dirt trap
3 ........... Thermal process safeguard (opens at approx. 95 °C)
4 ........... Cleaning T-piece
5 ........... Discharge funnel
6 ........... Immersion sleeve for the sensor of the thermal process safeguard
7 ........... Boiler return
8 ........... Boiler feed
