Connection To The Chimney Flue; Chimney Flue - Caminetti Montegrappa LIGHT 06 Installation, Use And Maintenance Manual

2.3.7
For the connection of the unit to the chimney ue, use only
non-combustible elements suitable to resist to the combustion
products and to the condensate (creosote) build-up.
The appliance works with negative pressure; to prevent
creosote from building up and be conveyed to the appliance
it is important that the connection to the chimney ue be
sealed and airtight.
The connection to the chimney ue should ensure easy
removal of soot and routine cleaning by means of a metal
brush.
After having placed the appliance in the exact position as
indicated under section 2.3.3, use rigid steel pipes with the
same section as the " ue exit pipe" (see technical sheet,
section 1.3) to carry out the connection to the chimney ue,
and perfectly seal the connection. (Use UL certi ed products
according to the standard UL-127
2.3.8
The passageway for conveying ue gases from the appliance
to the "chimney ue" (technically, chimney) is called " ue
conduit". The ue conduit must be built in compliance with
the standard UL-127
The chimney ue or the vertical exhaust vent for the ue
gases from a natural draught appliance must therefore meet
the following requirements:
be ue gas- and water-tight, and properly insulated from
combustible or ammable materials according to the usage
conditions.
be made of materials resistant to usual mechanical shocks,
heat, ue gases and possible condensate;
have all connections to the di erent elements of which the
ue conduit is made of properly sealed and airtight;
be as much as possible vertical; any angle from its axis must
not exceed 45°;
be installed at an adequate distance away from any
combustible or ammable materials by means of an air ow
or of an insulating material;
have an inner section preferably circular; we therefore
recommend piping installed within square or rectangular
chimneys (which otherwise must have a 1-to-1.5 internal sizes
max. ratio and a radius of curvature of the interior angles of at
least 20 mm);
the interior section must be invariable, free from constrictions
and independent.
A cleanout opening with a tight
connection betweeen the exhaust pipe an the appliance
should be provided for allowing access to the chimney ue
for purposes of inspecting and removing solid materials and
possible condensate.
