2-INSTALLATION
EXAMPLES OF CORRECT INSTALLATION
1.
Installation of Ø 150 mm flue with hole for the passage
of the pipe increased by:
minimum 100mm around the pipe if next to non
flammable parts such as cement, brick, etc.; or
minimum 300mm around the pipe (or as required by
rating plate) if next to flammable parts such as wood etc.
In both cases, install suitable insulation between the flue
and the ceiling.
Always check and respect the data tags on the flue,
in particular the minimum safety distances from
combustible materials.
The previous rules also apply for holes made in walls.
2.
Old flue, minimum tube Ø150mm with the inclusion of
an external access door for chimney cleaning.
3.
External flue made of insulated stainless steel pipes,
i.e. with double walls minimum Ø150mm: all securely
mounted to the wall. With windproof chimneypot. See
fig. 7 type A.
4.
Ducting system using T fittings that allow easy access
for cleaning without having to remove the pipes
