Installation
Example 60/100:
2 x 1 metre extension = 2.0 m
2 x 90° bend = 2.8 m
Total effective length = 4.8 m.
Maximum allowed is 12 m. So this is allowed.
Example 80/1250:
2 x 1 metre extension = 2.0 m
2 x 90° bend = 3.2 m
Total effective length = 5.2 m.
Maximum allowed is 35 m. So this is allowed.
Take the flue terminal clearances into account when plan-
ning the layout of the place of installation (see
subsection 1.9.1: "Siting the flue terminal" on page 19).
Maximum wall thickness without extensions is 415 mm.
Maintain a minimum side clearance of 5 mm (
Ensure the flue is adequately supported. Buderus recom-
mend securing each flue extension with a minimum of one
wall bracket.
The additional flue parts listed can be ordered from your
supplier.

Vertical adaptor (60/100 --> 80/125) is re-
quired for 80/125 flue gas systems, because
the flue outlet of the boiler is 60/100.
