SECTION 7
VENT DUCTS AND PIPES
For the air intake/flue gas venting system, specific manufacturer-approved, condensate
acid-resistant pipes and systems must be used, resistant to the etching of condensate
acids.
Flue gas venting pipes are to be installed at an angle towards the boiler so as to allow
condensate to run towards the combustion chamber, which is designed for condensate
collection and drainage.
If this is not possible, condensate collection and drain conveying systems must be
provided condensate stagnation areas.
