1.7.3 Maximum Flue length (L)
The maximum pipe length (L) of the air supply and flue
gas exhaust pipes for the 600 Series condensing gas
system boilers is determined by the total pressure loss
of all components in the flue gas exhaust / air supply
system.
Maximum length of horizontal or vertical extensions for
60/100 flue system is L = 7.5 m. Maximum length of
horizontal or vertical extensions for 80/125 flue system
(special adapter required) L = 20 m (see fig. 14 and
fig. 15).
Take the flue pipe clearances into account when
planning the layout of the place of installation (see
subsection 1.7.1: "Siting the flue terminal" on page 21).
Maximum wall thickness without extensions is 415 mm.
Maintain a minimum side clearance of 8 mm (see
fig. 12).
