INSTALLATION
THE SMOKE CHANNEL
• if in metal must have a CE marking (EN 1856-2) or
similar national law;
• cannot be in flexible metal material
•
to check the flow, a shutter is advised for draft over
25 Pa
THE CHIMNEY FLUE:
• must have a draft capable of creating negative
pressure ideally around 12 Pa. Lower drafts can
cause leaking smoke if the door is open; higher
values tend to generate fast combustion by
reducing the yield
• must be correctly sized to meet smoke evacuation
(EN 13384-1)
• must preferably be insulated, in steel with a circular
inner section. If rectangular, the inner edges must
have a radius under 20 mm and a ratio between
between the inner dimensions <1.5
• normally have a minimum height of 3-4 metres
• maintain a constant section
• be waterproof and thermally insulated to guarantee
draft.
• preferably create a collection chamber for
unburned fuel and any condensate
• be at least category T400, with an adequate
resistance to soot fireIf pre-existing, it must be
cleaned to avoid risk of fire.
EXTERNAL AIR INTAKE
To re-integrate burnt oxygen during product fun-
ctioning, you need to have an installation premises
suitable for the external air intake.
Once the product is faced, the Ø 14 cm pipe (A) must
be connected so that it does not remain closed in the
facing and takes in air from the air intake.
In accordance with local regulations, the air intake can
be mounted outside or in suitable rooms not subject
to depression.
