Flue connection
The flue must have internal dimensions not
exceeding 20 x 20cm or diameter 20 cm; in case
of greater dimensions or poor flue conditions (e.g.
cracks, poor insulation, etc.) it is recommended
to insert a stainless steel pipe in the flue (lining)
of adequate diameter for its entire length, up to
the top.
Check with adequate instruments that there is
proper draft. This type of connection assures flue
gas extraction even in the event of temporary
power outage.
The base of the flue must be fitted with an
inspection port for periodic check up and cleaning,
which must be done yearly.
Ensure a wind-proof cowl is installed according to
regulations in force.
