REPLACEMENT OF THE GAS
it
CYLINDER
The gas cylinder must be replaced in the open
de
air, away from heat sources, in an atmosphere
without flames.
es
Only the following supplied components must
fr
be used for connection of the gas cylinder to the
heater:
nl
• Liquid gas flexible hose;
• Gas pressure regulator.
pt
da
The gas regulator is provided by a safety valve,
this valve is directly controlled by button (Pic.
fi
8). The purpose of this safety valve is to avoid
no
abnormal leakage.
sv
PLEASE NOTE:
• If the gas regulator is used outdoor, it
pl
must be protected from water and rain;
ru
• The vent (hole) on the cap of the regulator
must be clean, there mustn't be anything that
cs
obstruct it;
• Don't lift or move the gas bottle from the regu-
hu
lator, but use the proper handle on the gas bot-
sl
tle;
• After ten years from the manufacturing date
tr
(see the mark on the regulator body), the regu-
hr
lator must be replaced even if it seems working
fine.
lt
CAUTION: In the event of replacement due
lv
to breakage or maintenance, original spare
et
parts must be used. See the appropriate
section (Par. "11. CLEANING AND MAINTE-
ro
NANCE").

►To connect the heater to the gas cylinder:
bg
CAUTION: ALL THREADING IS SINISTRAL,
I.E. THEY ARE TIGHTENED IN AN ANTI-
uk
CLOCKWISE DIRECTION.
bs
►4.1.Screw the gas hose on the heater fitting
(Pic. 4).
el
►4.2.Install the pressure regulator on the gas
cylinder. Make sure there is a gasket present on
zh
the regulator (if envisioned by the type of con-
nection) (Pic. 5).
►4.3.Connect the gas hose to the pressure reg-
ulator (Pic. 6).
►4.4.Open the gas cylinder cock (Pic. 7).
►4.5.Press the regulator release button (Pic.
8). Check tightness of fittings using soapy
water: bubbles indicate a gas leak (Pic. 9).
Several gas cylinders can be fitted together to
obtain greater autonomy. The use of 30 kg gas
cylinders is recommended, up to heating ca-
pacity of 33 kW. Over the power of 33 kW use
gas cylinders with greater capacity. The use
of gas cylinders with suitable capacity is rec-
ommended in order to prevent problems due
to lack of gasification of the fuel. The correct
functioning pressure (see data plate applied to
the heater) is given by the regulator supplied or
an equivalent model.
►►5. CONNECTION TO THE ELEC-
TRICITY MAINS
VERIFY IF YOUR ELECTRONIC SYSTEM IS
EARTHED CORRECTLY.
Before connecting the heater to the mains, en-
sure that the supply voltage and frequency are
correct (see data plate attached to the heater).
The connection to the mains electricity (Pic. 10)
must be made in compliance with the National
Standards in force.
►►6. IGNITION FOR MANUAL
MODELS (... / ...M / ...DV / ...M DV)
IMPORTANT: For ... DV / ...M DV models,
check the position of the transformer switch
(220-240V / 110-120V) (Pic. 11). If the voltage
set on the appliance does not correspond to
that supplied by the mains, the voltage must
be adapted. Loosen the 2 screws fastening
the cover (Pic. 12), move the switch to the
supplied voltage value (Pic. 13) and refit the
cover (Pic. 14).
● 6.1. HEATING MODE:
►6.1.1.Turn the "O/I" switch to position "I" (Pic.
15).
►6.1.2.Press the gas button fully home and
hold it down (Pic. 16).
►6.1.3.Activate the piezoelectric igniter fully
home and repeatedly (Pic. 17), keeping the gas
button pressed (Pic. 16).
►6.1.4.After ignition of the flame, hold the gas
button down for about 15 s (Pic. 18).
►6.1.5.Release the gas button (Pic. 19).
In the event of a power cut or if there is no gas
supply, the appliance will switch off. The heater
does not switch back on automatically. It must be
