All measurements are in mm.
The following applies for the horizontal pipe: slope of at
least 5 mm per metre of pipe to the water heater.

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.
