IMPORTANT WARNING
The following instructions regarding the sizing of the exhaust and ventilation pipes
are provided as guidelines only. The actual sizing and design must be determined
and drafted by qualified and certified technicians in compliance with the
regulations and standards in force!
EXHAUST PIPE
Ensure adequate ventilation to the engine and its environment, as well as a suitable exhaust
gas evacuation system away from doors and windows.
Exhaust gases and oil fumes can be lethal! Do not run the engine without a
suitable supply or fresh air and discharge the gases into the atmosfhere!
Make sure that the pipes and mufflers are suitably supported, equipped with expansion joints
and protected against accidental contact. Prevent condensate from getting into the engine
through the exhaust.
The exhaust gas pipes are usually made out of smooth unwelded steel tubes (UNI 1293) or, in
special cases, of stainless steel piping. The pipes must discharge the gases into the
atmosphere where they cannot cause harm or inconvenience, away from doors, windows or
air intakes. They must terminate with a fixed rain cap. Pipes installed through walls must be
provided with thermal insulation along the length running through the wall, to prevent the
transmission of heat to the wall.
The joints between the separate lengths of pipe must be perfectly tight to prevent any leaks.
(Flanged joints with gasket are the best solution).
To prevent the condensate from getting to the engine, provide a condensate collection pan
which must be periodically drained through a plug situated at the lowest point in the vertical
pipes.
