Separate ventilation air and flue gas routing
(type C
The boiler draws combustion air from outside via a separate supply
pipe routed through the external wall, and expels flue gas to the atmos-
phere via a shaft leading through the roof.
The connection piece to the chimney is designed as a coaxial pipe.
This balanced flue system is used if the existing chimney is unsuitable
for routing combustion air due to its dimensions or characteristics
(deposits).
For a detailed description, see page 31.
