Roof discharge (see figures 10 and 11).
Type:
M2000 DDV SE HR/VR
Manufacturer:
Meulink & Grol
Pipe material flue tube:
Thick-walled aluminium with lip ring seal.
Pipe material air supply:
Thin-walled galvanised steel plate.
Pipe diameter BFM 30:
Ø 80 / 125 mm
BFM 50:
Ø 100 / 150 mm
BFM 80:
Ø 130 / 200 mm
Angle:
45°/90° (max 2)
these flue configurations.
These will each equate to 1 metre of flue length.
The maximum flue configuration is therefore 7000 mm
pipe, 2 bends (45°/90°) and a lead-through set.
