4.1. INSTALLATION ON FLOOR OR CEILING
The space heater can be installed on a support base, which must be:
• stable and horizontal
• made of non-combustible material
Accessories include support hooks to suspend the heater by
hooking it to the ceiling with ropes and/or chains of appropriate
capacity and length, to be attached to the four suspension points
Warning
Make sure that the ropes and/or chains form an angle not
more than 5° with vertical to the ceiling, that the ropes do
not cross, and that a different rope is used for each hook.
The minimum distance from surrounding walls, floor and/or ceiling
must always be at least 1 metre.
4.2. POWER CONNECTIONS
Warning
The power line must be earthed and fitted with a residual
current circuit breaker.
The power cable must be connected to a panel fitted with
a cut-out.
Before switching on the heater and, therefore, before plugging it into
the electrical power supply, check that the power supply
specifications are the same as those stated on the identification
plate.
Warning
The heater is fitted with a temporary power cable, used for
the working test.
L-L 196.00-BM
NO
EN
Warning
The temporary power cable must be removed and replaced
with a H07RN-F cable having a section of at least 1.5
2
mm : a larger section is required if the cable is more than
25 metres long.
The cable must be stripped, leaving the earth lead at least
2 cm longer.
If any room thermostat or other accessories are connected to the
system (such as the timer for example) this must be done by
connecting the electrical cable to the thermostat plug (c):
• Take the plug (c) out of the power switchboard, open it and
remove the electrical jumper between terminals 2 and 3 of the
plug;
• Connect the thermostat electrical cable to terminals 2 and 3 of the
thermostat plug (c);
• Close the plug again and plug it back into the power switchboard.
Warning
Never attempt to switch the heater on or off by connecting
the room thermostat (or other control devices) to the
electrical power line.
The installation and connection of all the other accessories are
described in the specific instructions included with each accessory,
together with operating instructions.
The electrical diagram shown in this manual refers to the electrical
connection only.
4.3. CONNECTION TO HOT AIR DELIVERY DUCTS
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.
4.4. CONNECTION TO FUEL SUPPLY
Warning
The heater must be installed, set up, and used in
compliance with all applicable regulations.
Connection to the diesel supply pipe can be made by connecting the
fuel tank to the burner pump:
• directly, i.e., by using the burner's diesel pump, in conformity to
the dimensions and lengths specified in the burner instruction
manual attached hereto.
• indirectly, i.e., by using an auxiliary diesel circulation pump. In this
case, contact a Customer Service Centre to ensure correct sizing
of the fuel system.
4.5. CONNECTING BURNER TO "SNORKEL" AIR INTAKE 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.
