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 plugging the heater into the electrical power supply, check
that the power supply specifications are the same as those stated on
the identification plate.
The electrical power cable must be connected in conformity to the
polarity specified on the main terminal board of the electrical panel:
phase (L) and neutral (N).
Warning!
If polarities L and N are incorrect, the space heater
may stop a few seconds after it is switched on for the
first time.
A models may be connected to a room thermostat
or
other
accessories (such as the timer) by connecting to the thermostat plug
(10).
Warning
Never attempt to switch the heater on or off by
connecting the room thermostat (or other control
devices) to the electrical power line.
Installation and connection of room thermostat are described in the
specific instructions enclosed.
The electrical diagram in this manual shows only the electrical
connection of the accessory to the existing electrical system of the
heater.
Warning
Do not connect any air distribution hose: this will
cause a severe fire hazard!
CONNECTION TO GAS CYLINDER
The heater must be connected to an appropriately sized gas
cylinder. A gas supply stopcock must be installed between the heater
and the cylinder.
Warning
All of the connections have left-hand threads, and
must therefore be tightened by turning anticlockwise.
Warning
The dimensions of the gas cylinder must be based on
the required gas flow rate and supply pressure.
The supply pressure to the pressure regulator must
always be greater than 2 bar.
The heater is supplied complete with gas hose (a) and pressure
reducer (c) with fittings (d) for connection to different types of
cylinders.
Depending on the country of destination, the heater may be
supplied with various types of gas pressure regulator.
Warning
The installer is responsible for guaranteeing that the
correct fitting is used for the connection to the gas
cylinder.
Always tighten the cylinder fitting first, and then the
pressure regulator, which has a swivel fitting.
TYPE I
• pressure regulator with G5 fitting for AT-BG-CY-DK-DE-EE-LT-
LV-MK-MT-RO-TR-NL.
• G5/G2 fitting, with G2 fitting for G2 for BE-CZ-ES-FR-HR-HU-
LU-PL-PT-SI-SK.
• G5/G1 fitting, with G1 fitting for IT-GR
• G5/G7 fitting, with G7 fitting for FI - IE – GB (only if requested)
• G5/G5R fitting, with G5R fitting for CH – NL (only if requested)
• G5/G9 fitting, with G9 fitting for SE – NO (only if requested)
• seal for NL, to install on G5 pressure regulator for NL.
TYPE II
• pressure regulator with G7 fitting for FI - IE - GB.
TYPE III
• pressure regulator with G9 fitting for SE - NO.
Warning
The seal of the fittings must be checked by pouring
liquid soap on them: the appearance of bubbles
indicates a possible gas leak.
Warning
Propane and buthane are heavier than air, therefore
any gas leakage can cause gas stagnation on the floor
or in any underlying room.
A safety valve (b) may be ordered for protection in case of a
broken gas hose. Installation of this valve is mandatory if required by
local installation laws and regulations.
The gas cylinder must be changed and replaced in an open room,
away from sources of heat and open flame, taking care to check that
the instructions in this paragraph are followed.
Warning
Always make sure that the seal (if required by the
fitting) is present between the reducer and the
cylinder.
Make sure that the gas hose has been tightened
without being twisted: any stress from twisting can
seriously damage the hose.
