Connection To The Flue - Jolly Mec J20 Ficha De Montaje, Uso Y Mantenimiento

Connection to the flue

The connection to the flue must be preceded by
a condensate drain connection to be installed at
the smoke extractor outlet. It is recommended to
install a curve and then a T-fitting that allows the
inspection and collection of condensate (see image
below):
A = 45 ° CURVE
B = T-FITTING
C = VERTICAL SECTION
The high performance of the
boiler results in a very low flue
gas temperature which is a pos-
sible consequence of the forma-
tion of condensation inside the flue and
the smoke channel. Vertical installation
without the T-piece is therefore prohibi-
ted as previously illustrated.
In the absence of the T fitting, the conden-
sate falls back into the smoke extractor
compartment and can cause it to break. In
this case the warranty will not apply.

The joint between the boiler and the flue must be
installed using suitable tubes (min. T200). Use is
forbidden of flexible metal tubes, in cement fibre
or aluminium. The slope of the smoke duct must
not have horizontal sections over 2 metres
and must have a minimum 3% inclination. The
first change of direction must take place after at
least 1.5 metres of the vertical section. Inspect the
base of the smoke duct
with periodic controls. It is forbidden to connect
the same smoke duct on multiple equipment. Keep
the smoke duct an adequate distance from any
flammable parts or parts sensitive to heat. Refer to
the instructions given by the manufacturer of the
flue for the distances to respect.
