Type 4 L min. > 0 m L min. > 4.5 m L > 6.6 m
80/80 L max. = 4.5 m L max. = 34 m L > 6.6 m
Type 5 L min. > 0 m L min. > 11.5 m L > 6.6 m
80/80 L max. = 11.5 m L max. = 56 m L > 6.6 m
Air intake length 1 m.
L = total length of gas intake and exhaust ducts.
I
f the exhaust gas duct length is longer than 6.6 m, you will need a condensate drain
For coaxial systems, the maximum development value L, mentioned in the table above also takes into accout an elbow.
For twin flue isystems the maximum development value L, mentioned in the table includes the exhaust gas/air intake terminal.
Type 5 outlets should respect the following instructions:
1- Keep the same ø 80 mm for the gas intakes and exhaust gas ducts.
2- If you need to insert elbows in the gas intake and exhaust gas ducts, you should consider for each one the equivalent length
to be included in the calculation of developed length.
3- The exhaust gas duct should jut above the roof by at least 0.5 m.
4- The intake and exhaust gas ducts in Type 5 must be installed on the same wall, or where the exhaust is vertical and the air
intake horizontal, the terminals must be on the same side of the building.
