Connection To The Flue - Horus ALMA Manuel D'installation

Alternatively, we suggest you use industrial insulated pipes. These can be used on the outside without causing condensation
problems.
WARNING
Always use pipes and connections with appropriate close-fitting gaskets. All the sections of a flue must be easily controlled and
removed for periodic internal cleaning.
WARNING
Each 90° bend in the fume exhaustion pipe must be fixed, if possible, with adequate "T" fittings.
WARNING
Inserting a grating at the end of the fume exhaustion pipe is forbidden. It could cause the stove to break down.
CONNECTION TO AN INSULATED OR DOUBLE-WALL FLUE
The internal dimensions of the external flue pipe must be of minimum 10 x 10 cm, or 10 cm diameter, and of maximum 20 x 20
cm, or 20 cm diameter.

By using adequate tools, check that there is a flue draught of at least 12 PA.

Only use insulated stainless-steel pipes (double-wall) with a smooth inside lining (flexible stainless steel pipes are not
allowed) securing them to the wall.

Allow space for periodic checks and annual cleaning at the lower end of the flue.

Connect the stove to the flue by using adequate pipes and fittings.

Make absolutely sure to install an anti-draught chimney in compliance with current regulations.
It is forbidden to install flues as shown in Figure

18.CONNECTION TO THE FLUE

For the best possible stove functioning, the connection to the flue exhaustion pipe or system must have a positive gradient of no
less than 3% in horizontal pipes. The overall length shall not be more than 2 m whereas, in vertical pipes, between a "T" fitting
and other fittings (change of directions) there must be a distance of minimum 1.5 m and maximum 3 m by using adequate tools,
check that there is a flue draught of at least 12 PA. Allow space for periodic checks and annual cleaning at the lower end of the
flue. Connect the stove to the flue by using adequate pipes and fittings. Make absolutely sure to install an anti-draught chimney in
compliance with current regulations.
