M360 Firebox Installation Instructions February 2015
1.3 CHIMNEY STACK
The chimney stack must comply with the following requirements:
it must have an internal section and shape the same as the flue (A);
it must have a useful outlet section (B) of not less than twice that of the flue (A);
the part of the chimney that emerges from the roof or remains in contact with
the outside (e.g. in the case of a flat roof), must be covered with brick or tile
elements and in any case well insulated;
It must be built in such a way as to prevent the penetration of rain, snow and
foreign matter into the flue and to ensure that in the event of winds from all
directions and angle, discharge of the combustion products is assured
(chimney stack with down-draught cowl).
Recommended distances for correct chimney operation.
To ensure trouble-free operation of the chimney and allow correct dilution of the
products of combustion in the air, the chimney stack must be installed at the
distances given below:
6-8 metres from any buildings or other obstacles that are higher than the chimney
stack;
50 centimetres higher than any obstacles located at a distance less than 5 me-
tres;
outside the reflux area. The size and shape of this area differ according to the
angle of inclination of the roof and it is therefore necessary to adopt the minimum
heights shown below.
