It is compulsory to plan a chamber for the collection of solid material and/or any condensation, which can be
inspected through an airtight door.
It is compulsory for you to observe the provisions of standards UNI 9615 and 9731 for the sizing of the chimney
cross-section and in any case that you avoid installing ducts with a cross-section of less than 150 mm.
In the case of larger cross-sections, it may be necessary to insert a steel duct inside the masonry one.
Direct wall discharge is not permitted.
The steel pipe must be suitably insulated with material which is resistant
to high temperatures and sealed off from the external chimney.

Baffles
In certain installation conditions there might be an acoustic resonance due to the pressure differential in the fluid
dynamics between combustion air inlet and exhaust fumes outlet.
To solve the problem removable baffle sections are fitted in each air inlets of the Compact 24.
After the first ignition if a background noise becomes audible 1 or 2 baffle sections must be removed, or more
until the resonance ceases.
