Sime SOLO HE EV
thermal units are classified as “Type B” (B23P)
and “Type C” (C23P), while the smoke discharge and combus-
tion air intake system must be made as explained below.

IT IS FORBIDDEN
– Do not block or reduce the size of the air vents of the
place of installation or the appliance.
“TYPE B” installations
The combustion air must be drawn through a permanent open-
ing, which MUST be present in the room where the appliance is
installed and MUST be made in accordance with the standards
and laws in force in the country where the appliance is used.

The flue plays a crucial part in the installation’s operation. If it
is not made according to specific criteria, it may cause burner
malfunctions, noise amplification and the build up of soot, con-
densate and deposits.
A flue must therefore satisfy the following requirements:
– it must be made of waterproof material resistant to the fume
temperatures and the relative condensations
– it must have sufficient mechanical resistance and low ther-
mal conductivity
– it must be perfectly sealed to avoid cooling of the flue itself
– it must lie as vertical as possible and must be topped with a
static aspirator to ensure constant and efficient evacuation of
the combustion by-products
– in order to prevent wind from creating pressure zones around
the chimney such that they may prevail over the ascending
forces of the flue gases, the outlet must emerge by at least 0,4
m above any structure adjacent to the chimney itself (includ-
ing the top of the roof) less than 8 m
– the flue must have a diameter not inferior to that of the
thermal unit coupling; for flues with square or rectangular
cross-section, the inner cross-sectional size must be 10%
larger than the thermal unit coupling.
“TYPE C” installations
In order to use “Type C” installations, the thermal units must be
converted using the kit code 8098816 (1).
