The space heater is set to operate with direct distribution of air.
Nevertheless, it can be connected to appropriately sized air
distribution channels, if required, with maximum diameter and
length as shown in the "TABLE OF TECHNICAL CHARACTERISTICS."
Warning
Before starting the heater, check that the direction of
rotation of the fan matches the direction shown on the fan
itself.
The air distribution channels can be connected by using the various
available accessories, placing the connections on the front, side, or
top as required.

compliance with all applicable regulations.
Warning
Before installing, check the gas supply conditions
required for the type of gas chosen and for the EU country
of installation (Tables I and II).
The gas supply pipe must be properly sized, conform to the installed
thermal power, and guarantee the necessary conditions for gas
supply.
Warning
The gas supply pressure must be guaranteed during
heater operation and not with the heater off.

4.5. CONNECTING BURNER TO "SNORKEL" DEVICE AND SETTING
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.
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".
