heated in order to suck in clean air and avoid depleting the oxygen
in the room.
The connection pipe must be rigid to prevent shrinking due to air
intake depression. It must have a minimum diameter of 100 mm and
maximum length of 6 metres.
Warning
If the hose is too long, remove the excess without leaving
loops and/or curves which may hinder air suction.
The end part of the suction hose should be connected to a wall
accessory with safety grille to prevent small animals and/or debris
from entering the hose.
Warning
Burner air should be adjusted in accordance with the
indications listed in the "TECHNICAL CHARACTERISTICS
TABLE".
4.7. CONNECTION TO EXHAUST DUCT
Exhaust ducts must be in steel and conform to EN 1443.
Efficient combustion and trouble-free working of the burner depend
on efficient flue draft.
The unit must be connected to the chimney flue in compliance with
current legal regulations and in line with the following guidelines:
• The path of the flue pipe smoke should be as short as possible
and should slant upwards (minimum height 1 m);
• There should be no sharp curves in the pipes, and the diameter of
the pipes must never be reduced;
• there must always be a wind deflector to prevent the entrance of
rain and to prevent smoke from being blocked by the wind;
• flue draft must at least equal the level in the Technical
Specifications.
• every heater must have its own chimney;
The following diagrams show possible flue positions:
A) Minimum 1 m
B) As short as possible
