INSTALLATION

FLUE CONNECTION

Operation related to the ambient air

(Type B23 Installation)

To ventilate the boiler room, it is required to install- in accordance with combustion regulations - a

fresh air inlet of at least 150 cm

or to provide a connection with other rooms to ensure a fresh air

supply.

To get optimum sound comfort, it is recommended to:

- install the boiler on a solid base (eg. concrete support) instead of a hollow base (eg. concrete

blocks), which could create a resonance volume.

- uncouple the boiler from the system hydraulic circuit by installing a hose connection on the

inlet and outlet circuits and make sure that the hose connections are not taut or twisted.

- increase the gas exhaust duct diameter if required (min 80 mm diameter).

- uncouple the gas exhaust circuit from the flue pipe wall, adding soft insulation between the

pipe and the wall, so that the vibrations from the operating boiler are not transferred to the

building walls.
