1.3. CHIMNEY
The cooker is connected to the chimney via 130 mm diameter sliding
rosette (C-25 and C-30P cookers) i.e. 150 mm diameter sliding rosette (C-
35 cooker). It is necessary to execute the connection of the rosette and the
chimney tightly and impermeably. If the cooker is separated from the
chimney opening (not recommended) the connection is made via standard
130 mm diameter smoke venting pipe (C-25 and C-30P cookers) i.e. 150
mm diameter smoke venting pipe (C-35 cooker) –see
chapter 4.3
.
We also advise to equip the chimney with solid material and possible
condensation products collection chamber and to install the chamber in
question beneath the smoke channel inlet, in a manner which allows easy
access and inspection via impermeable door.
IMPORTANT
BEFORE connecting to the chimney it is necessary always to make a
calculation (according to EN 13384 and all other standards for the
chimney dimensioning)!
The chimney has a very important function of the smoke exhaust at
solid fuel heating devices and therefore MUST BE well and properly
dimensioned!
1.3.1. CHIMNEY CAP
Chimney cap must fulfill the following prerequisites:
identical internal diameter to that of the
chimney,
operational exit cross-section no less than the
double inner diameter of the chimney –see B ≥
2×A in the Figure beside,
constructed to prevent rain, snow, leaves and
other foreign bodies from entering the chimney,
constructed to enable expulsion of combustion
products in case of wind from any direction and incline,
installed to enable proper dispersion and dilution of combustion
products outside the reflux zone (backflow) because the counter
pressure occurs here. Therefore, it is necessary to adhere to limitations
listed in
Figure 2
,
mechanical appliances for flue gases suction are not allowed.
