2.4.43 Installation of flue gas connection through cover on integral fuel
hopper side
For assembly of the flue gas collection set (accessory: DUO 002) see own installation instructions.
Attach the flue connection piece to the flue outlets of the pellet boiler.
a) Ins
tall the exhaust pipe upward to the flue (45° is the ideal angle). Maximum exhaust pipe length is 3 m.
Information!
Any section of this exhaust line that is horizontal or inclined less than 30 degrees cannot 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 Induced draught fan can cause sound transmissions that create noise pollution.
e) The boiler is a low-pressure boiler, which 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 must be insulated with a thickness of at least 2 cm.
g) The entire exhaust line must be able to open (i.e. appropriate cleaning openings must be included). The first
cleaning opening must be in the first bend of the exhaust pipe.
h) A draught limiter is needed if the maximum draught (see technical data in section 4.4.) is exceeded during
operation.
Information!
Access must be available to the water tank (for checking and refilling) and to the blower motor (for
service and maintenance work). Therefore, do not lay the exhaust pipe directly over the top.
Attention!
The configuration of the exhaust line must comply with technical fire protection requirements in ac-
cordance with the applicable regulations, standards, and guidelines – see section 2.4.1. „Minimum
service clearances for fire protection, cleaning, and maintenance.“
