Roof outlet along an external steel flue pipe

One of the installation solutions which could be used is to position the boiler near a perimeter wall of the
home (see figure below) so that the smoke is discharged along an external flue pipe. Here are some of the
provisions of standard UNI 7129 for this particular system configuration:
- Always make sure there is an inspection valve to allow periodic and efficient cleaning, as well as the
venting of any condensation that may have formed;
- The chimney must under all circumstances be wind-proof and rain-proof;
- Make sure the smoke outlet duct is suitably insulated in the section that crosses the wall.
It is advisable for the smoke outlet duct, if it is completely outside, to be made of double-wall stainless steel
to guarantee both greater resistance to the atmospheric agents as well as the appropriate temperature of
the smoke outlet.
