• Maximum vent lengths based on equivalent straight
runs only. Include rigid pipe and fittings in overall
equivalent length calculations.
• Flexible venting installations use single wall
polypropylene to pass flue gasses to base of chimney,
then flexible venting to get them to termination at the
top.
• Combustion air is not supplied through masonry
chimney. Combustion air must be from outside using 3"
[80 mm] single wall polypropylene.
• Position boiler to use minimum of rigid single wall
polypropylene venting to the chimney.
• Follow venting manufacturer's instructions on assembly
and clearances to maintain.
•
Avoid sharp bends in flexible venting.

Note
Flexible vent systems shall only be run vertical.
Horizontal runs before adapting to flexible must
be rigid pipe.
