Fumes Exhaust System Product Requirements; Combustion Products Outlet Quota - Extraflame HP 15 Manual Del Usuario

COMBUSTION PRODUCTS OUTLET QUOTA

The outlet quota is determined by measuring the minimum height between the roof covering and the lower point of the fumes
expulsion section into the atmosphere; this quota must be outside the re ux area and at an adequate distance from obstacles
which hinder or make the expulsion of the combustion products di cult or from openings or accessible areas.
Re ux area
The outlet quota must be outside the re ux area calculated according to the indications below.
Near the ridge one considers the lowest between the two.
Bu er area for outlet quota
Clear area for outlet quota above the roof slope (
REFERENCE
c
a
The outlet of a chimney/ducted system must not be near obstacles that may create turbulence areas and/or prevent proper
expulsion of combustion products and maintenance operations to be carried out on the roof.
Verify the presence of other chimney caps or skylights and dormers.

FUMES EXHAUST SYSTEM PRODUCT REQUIREMENTS

Temperature class
In the event of a pellet appliance, temperature classes below T200 are not allowed.
Soot re resistance class
The fumes exhaust system interlocked with appliances supplied by solid fuels require soot re resistance, and the speci cation
must be indicated by the letter G followed by the distance from combustible materials in millimeters (XX) (in compliance with
UNI EN 1443) .
In the event of pellet appliances, the fumes exhaust systems must be airtight; if double designation elements are used (G and
O, with or without seal elastomer) for connecting the appliance to the chimney, one must comply with the minimum distance
XX in millimeters, indicated for designation G; in the event of re due to soot, one must ensure the restoration of the initial
conditions (by replacing the gaskets and damaged items and cleaning those remaining in use).
Ignition tests
Operation of the appliance must be veri ed with an ignition test, i.e.:
Š for mechanical feed appliances, one must complete the ignition test, verify proper operation for at least the next 15
minutes and adjust the switch-o ;
For appliances installed in a hot water heating system (closed replaces, thermo-stoves), testing must also extend to the entire
hydraulic circuit.
