1 GENERAL RULES
1.1 Chimney or smoke stack
Every stove must have a vertical duct, called a smoke stack, to discharge to the external air by means of natural
draught, the smoke and fumes produced by combustion.
The smoke stack must conform to the following requirements:
It must not be connected to any other fireplace, stove, boiler or ventilation canopy of any type (fig.1)
It must be adequately separated from combustible or inflammable materials by air gaps or appropriate
insulation;
Its internal cross section must be uniform and preferably circular: square or rectangular sections must have
rounded corners with a radius not less than 20mm.and a maximum ratio between the walls of 1 to 5; interiors as
smooth as possible and without restrictions; smooth, uninterrupted bends with no bends greater than 45° (fig.
2);
Each appliance must have its own smoke stack with a cross section equal to or greater than the outlet flue from
the stove and with a height not less than 3.5-4 m.;
Two stoves, a fireplace and a stove, a stove and a wood burning oven etc. must never be used together in the
same room…. because the draught from one could adversely affect the draught of the other. Neither should
collector ventilation ducts be allowed as these can reduce the air pressure in the room where the appliance is
installed, even if they are installed in adjacent but communicating rooms;
Fixed or adjustable openings must never be made in the smoke stack for the purpose of connecting different
appliances from the one it has been designed to serve;
Even if the smoke stack is oversized, it must not be used for the passage of other air ducts or pipework
installations;
It is recommended that the smoke stack is equipped with a chamber at the base of the stack for the collection of
solid materials and any condensation, designed to be checked through an air-tight window and easily opened;
When parallel smoke stacks are used it is advised that one of the wind-proof chimney pots be higher than the
other (fig.3).
