Removal of combustion products
The combustion product exhaustion ducts must be installed by qualified personnel and must
comply with current legislation and standards.
The Evolution Solar HDX boiler 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:
Exhaustion duct position
Minimum distance
(mm)
A under a cornice
300
B between two horizontal ducts
1000
C from an adjacent window
400
D between two vertical ducts
1500
E from an adjacent ventilation grille
600
F under a balcony (*)
300
G under a window
600
H under a ventilation grille
600
I from a recess in the building
300
J from a corner of the building
300
K from the ground
2500
L from a vertical or horizontal duct or outlet (**)
300
M from a frontal surface at a distance of 3 metres from the fume outlet
2000
N as above, but with an opening
3000
(*) Providing the width of the balcony is not over 2000 mm.
(**) If the pipe is made of materials sensitive to the action of the flue gases, this distance should be over 500 mm.
Note: Spanish law also stipulates that the end of the exhaustion duct must be at a distance of at least 400 mm from any air intake
opening, and from the wall.
IMPORTANT: All accessories used for combustion product removal and air intake are to be
those supplied by DOMUSA TEKNIK.
