Ensure that the ues can be inspected regarding their free cross-section. For this,
provide an appropriate inspection aperture in the installation room, in consultation with
your local ue gas inspector.
Connections on the ue gas side are made using female connections with gaskets.
Always position female connections against the direction of the condensate ow. Install
thebalanceduewithaslopeofatleast3°towardsthegascondensingboiler.
Use spacer brackets to secure the sections in place (see installation examples).
Connectiontobalancedue
The calculated length of the balanced ue or standard ue is comprised of the straight
pipe length and the length of the pipe bends.
Example for a 60/100 system
1)
:
Straight balanced ue pipe. length 1.5 m L = straight length + bend length
1 x 87° bend
≙ 1.5 m L = 1.5 m + 1 x 1.5 m + 2 x 1.3 m
2 x 45° bends ≙ 2 x 1.3 m L = 5.6 m
Calculatingthebalanceduelength
Note: To avoid reciprocal interference between balanced ues routed above the
roof, we recommend maintaining a minimum clearance of 2.5 m between
balanced ues.
