The
‘equivalent load loss’
of an installation is the result of the sum of the total metres of the installation added to any
additional losses that are shown in the following table:
TYPE OF PATH OR ACCESSORY
LENGTH TO SUBTRACT FROM THE TOTAL
ALLOWED
90°bend 1 m
Horizontal stretch 45° bend 1 m
`T´accessory 1 m
Diagonal stretch 0,5 m
45 ° bend 0,5 m
The sum of these losses must be equal to or less than the maximum length allowed shown in the table of
limitations. If this is not met, the diameter of the smoke ducting to be installed must be increased:
LOSS OF EQUIVALENT LOAD ≤ MAXIMUM PERMITTED LENGTH
5.3.3 INSTALLATION IN TRADITIONAL-TYPE CHIMNEYS (see fig. 5.3 and 5.4)
If you wish to make use of an existing chimney structure, it is necessary to carry out some tests to check its seal. If
the existing chimney is not sealed, the situation could arise where there is a positive depression with respect to the
atmosphere, meaning that there could be an ingress leak into living spaces. If the seal is not fully tight, it is advisable
to put new pipework in.
If the cross-section of the chimney is excessively large, pipework with a maximum diameter of Ø 150 mm could be
considered, with it being advisable to also install insulation around this.
5.3.4 EXTERIOR STRETCH OF THE CHIMNEY (see fig. 5.5)
If an exterior stretch is anticipated for the chimney, it must meet the following requirements:
• The part of the installation that penetrates to the exterior must be made with insulated and double-walled pipes made
of stainless steel and attached to the building.
• This ducting must have an inspection hatch for regular maintenance tasks.
• The chimney must rise to the gable of the house, in line with the requirements stated in section 5.3.
