Combustion product removal
The combustion product exhaust ducts must be installed by qualified personnel and must comply
with current legislation and standards.
The
Fusion Hybrid Gas Condens
module is a sealed oil-fired boiler, and the combustion products
are therefore removed through an outlet pipe, with a separate air intake from outside. We
recommend that the position of the outside exhaustion duct is as shown in the figures and in the
table below:
Gas removal terminal position
Minimum distance
(cm)
A
From openings (e.g. doors, windows, ventilation grilles)
60(*)
B
Under a cornice or drainpipes
30
C
Under a gutter
30(**)
D
Under a balcony
30
E
From vertical or horizontal pipes

H

I
From the wall with the pipe to the front wall
120
J
From openings (e.g. doors, windows) under the roof
120
K
Between two vertical ducts
150
l
Between two horizontal ducts
100
M
From an adjacent vertical duct
50
N
From a front surface with openings
200
(*)
The end of the removal duct must be at least 40 cm from any opening in the façade.
(**)
If the pipe is made of materials sensitive to the action of the combustion gases, this distance should be at least 50 cm.
