Avoid installing completely horizontal sections.
The room where the heat generator is to be installed must not contain any existing or
envisaged smoke suction hoods in order to avoid depressurising the setting.
The air intakes must not be closed.
Make sure the flue pipe is kept clean, cleaning it at least once a year.
In the event of a fire in the flue pipe or duct, switch the boiler off
immediately and disconnect it from the domestic electricity mains

Roof outlet via an external steel flue pipe

4.4.1.
One possible installation solution is to position the boiler near a perimeter wall of the home so that the
smoke is discharged along an external flue pipe. Below are some 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.
