- It should always have the same diameter. It is recommended that it be circular, and never any
narrower than the boiler outlet.
- It is obligatory to install a fume inspection plate with condensation collection, to remove
the condensation generated in the flue.
Otherwise, the condensation may reach the inside of
the boiler and cause irreparable damage, which would not be covered by DOMUSA TEKNIK's
guarantee. The condensation pipe should lead to a drain outlet , as a large amount of water
may be generated. This connection must be made in compliance with the regulations for
draining off condensation water to the drain system.

It is recommended that a draught stabiliser
be installed to prevent any pressure drop
variations in the flue due to atmospheric conditions, which could affect correct boiler
combustion.
This draught stabiliser must be installed below the fume inspection plate to
prevent any leakage of combustion gases.
