2.3.27 Installing the exhaust pipe
a) Ins
tall the exhaust pipe upward to the flue (45° is the ideal angle). Maximum exhaust pipe length to flue 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) Do not push the exhaust pipe too far into the flue.
d) Do not seal the exhaust pipe completely into the flue. Connection with flexible exhaust pipe inlet into the flue.
The vacuum fan can cause sound transmissions that create noise pollution.
e) The LogWIN is a low-pressure boiler. This means that the flue gas system needs to meet the „N1“ seal integrity
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).
f) The entire exhaust line should be insulated to a minimum of 2 cm thickness in order to prevent or minimise
condensation.
g) A draught limiter is needed if the maximum draught (see technical data in section 4.4.) is exceeded during
operation.
Note!
We would recommend fitting outside the flue around ½ m below where the exhaust pipe intersects
with the flue.
Attention!
The configuration of the exhaust line must comply with technical fire protection requirements in
accordance with the applicable legislation, regulations, guidelines and standards – refer also to
section 2.3.3. Minimum clearances for fire protection, cleaning and maintenance.
2.3.28 Installing the thermal process safeguard
Connecting thermal process safeguard to thermal safety device
a) The thermal process safeguard and cleaning T-piece must still be accessible after installation.
b) The drain must be visible 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:
Minimum connection pressure of the thermal safety device: 2 bar.
It must not be possible to block the connection manually.
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
