The flue can not be realised with horizontal tracts. The flue must be realised with pipe with a diameter of 180 mm in stainless steel, appropriately
isolated and insulated.
The connection to the flue must be sealed.
When realising the flue, there must not be more than 2 direction changes, including the initial T-shaped fitting.
Chimney
The chimney is a device crowning the flue, used to ease dispersion of combustion products.
It must satisfy the following requisites:
Have a useful outlet section that is not less than the double of that of the flue on which it is inserted;
Be conformed in a way to prevent the penetration of rain and snow into the flue;
Be built in a way that, also in the case of winds from every direction and inclination, to ensure combustion exhaust.
The outlet height (where height means that which corresponds to the top of the flue, independently of any chimneys) must be outside of the so-called reflow
zone in order to prevent the formation of counter-pressures, which prevent free exhaust of the combustion products into the atmosphere.
It is therefore necessary that the minimum heights, indicated in the following figures, are respected:

FURTHER SPECIFICATIONS TO BE CONSIDERED
IT IS MANDATORY TO REALISE A FIRST VERTICAL TRACT OF AT LEAST 0.5 METRES IN ORDER TO GUARANTEE CORRECT FLUE GAS
EXPULSION.
Fix the pipes to the wall with the relevant metal collars in order to prevent any vibrations.
