2-INSTALLATION
EXAMPLES OF INSTALLATION
4
(DIAMETERS AND LENGTHS TO BE SIZED)
1. Flue installation 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 plate data) if next to flammable parts such
as wood etc.
In both cases, install suitable insulation between the flue
and the ceiling.
Always check and comply with the plate data of the
flue, specifically the minimum safety distances from
combustible materials.
The previous rules also apply for holes made in walls.
2. Old flue, pipe 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: all securely mounted on the wall.
With windproof chimneypot.
4. Ducting system using Tee fittings that allow easy
access for cleaning without having to remove the pipes
