For the installer
2.3.29 Installing the exhaust pipe
a) Install the exhaust pipe upward to the flue (45° is the ideal angle). Maximum exhaust pipe length 3 m.
CAUTION
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
included draught blower 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 EN 1856-2. 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. Section 4.4 or 4.6) is exceeded during op-
eration.
Note!
We would recommend fitting the draught limiter outside the flue. around ½ m below where the exhaust
pipe enters the flue.
DANGER
The configuration of the exhaust line must comply with technical fire protection re-
quirements in accordance with the applicable legislation. regulations. guidelines and
standards – refer also to Section 2.3.3. Minimum clearances for fire protection. clean-
ing and maintenance.
2.3.30 Installing the thermal discharge safeguard
Connecting thermal discharge safeguard to thermal safety device
a) The thermal discharge 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.
