COMBUSTION AIR
The burner air intake (3) can be connected outside the room to be
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.
To connect the air pipe to the burner intake:
• remove burner box cover (a)
• remove burner box closure panel (b)
• insert air pipe (c) into the hole on closure panel (b) and fix it to
Snorkel intake (d) on the burner
• reassemble burner box cover (a) by sliding it along air pipe (c),
making sure that air pipe (c) does not detach from Snorkel intake
(d)
• fix panel (a) on the burner intake by turning it upside down so that
air pipe (c) is locked.
