Maximum Flue length (L)
The maximum pipe length (L) of the air supply and flue gas
exhaust pipes for the 500 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 = 12 m. Maximum length of horizontal
or vertical extensions for 80/125 flue system L = 35 m (see
fig. 16 and fig. 17).
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 15).
Maximum wall thickness without extensions is 415 mm.
Maintain a minimum side clearance of 8 mm (see fig. 14).
