4-FLUE
EXAMPLES OF CORRECT INSTALLATION
1. Installation of Ø120mm ue with hole for the passage
of the pipe increased by:
minimum 100mm around the pipe if next to non
ammable parts such as cement, brick, etc.; or
minimum 300mm around the pipe (or as required by
data tags) if next to ammable parts such as wood etc.
In both cases, install suitable insulation between the ue
and the ceiling.
Always check and respect the data tags on the ue,
in particular the minimum safety distances from
combustible materials.
The previous rules also apply for holes made in walls.
2. Old ue, minimum pipe Ø100mm with the inclusion of
an external access door for chimney cleaning.
3. External ue made of insulated stainless steel pipes,
i.e. with double walls minimum Ø100mm: all securely
mounted on the wall. With wind-proof chimney cap. See
g. 7 type A.
4. Ducting system using T tting that allow easy access
for cleaning without having to remove the pipes
