parts.
The pipes must ALWAYS be installed according to the standards
and instructions of the manufacturer and anyway with the silicon
gasket supplied to guarantee its sealing.
• IT is prohibited to install dampers or other valves that can
obstruct the flue gas exhaust.
• IT is prohibited to install one flue in which flue gas or vapours of
other appliances (boilers, hoods, etc.) are exhausted.
