voltage value required.
110 V
240 V
If necessary:
• remove the cover;
• press deflector (8) to the position required;
• replace the protective cover.
Warning
The power supply must be provided with a good earth
and magneto-thermic mains switch.
Connect heater to gas cylinder (minimum 25 kg capacity) in the
following order: gas hose to heater, stop gas valve to gas hose, regula-
tor to stop gas valve, regulator to gas cylinder.
Warning
All gas connections have a counterclockwise thread.

OPERATING INSTRUCTIONS
• Set switch (4) for "A" models and (6) for "M" models on "0"/OFF
position; connect heater to mains with good earthing.
• Set regulator at the lowest pressure and press stop gas valve once.
• On "A" models only, set switch (6) on position
and after few seconds the combustion begins.
• On "M" models only, set switch (6) on position ON and while keep-
ing valve pressed, press piezo ignitor until ignition occurs. Keep
valve pressed for about 10-15 seconds, then release.
• You can now increase or decrease the output of your heater by
acting accordingly on the gas regulator.
If the heater does not start or run properly, please check following points:
• check mains connection;
• check that gas cylinder is full and that cylinder tap is opened;
• press safety stop valve button;
• on "A" models only, press the reset button up to 3 times max.
If the heater still does not run read carefully "OBSERVED FAULT,
CAUSES AND REMEDIES" chapter in this service book and make sure
that the reason of malfunction is clearly located and proper repair is
made before any re-start attempt.
STOPPING THE HEATER
Set main switch (6) on "M" models and switch (4) on "A" models
on "0"/OFF position or turn thermostat or other control device on the
lowest setting ("A" models only).
Turn off gas supply and pull out mains plug.
VENTILATION
Your heater can be used as a ventilation unit only. In this case do
not connect heater to gas cylinder.
• On "A" models set main switch (4) on position
• On "M" models set main switch (6) on position ON.
To stop ventilation set mains switch on "0"/OFF position.
SAFETY DEVICES
"A" models.
"A" model is equipped with an electronic device for the flame con-
trol. "A" model is moreover equipped with a device for airflow control.
This security device will prevent the flame to light in case of insufficient
or missing airflow. In case of failure the heater will stop and the pilot
lamp in the control box reset button will light up. A self-diagnostis sys-
tem will always check the airflow at start up. Airflow must be absent at
first and be present afterwards. On the contrary the heater will stop and
the control lamp (1) will light up. Avoid to start the heater before the
fan has stopped.
Warning
During proper heater work, the control lamp of the reset
button can blink for short periods for regular intersals:
this doesn't represent a malfunction warning.
While in case of heater "block", instead, the warning
lamp will remain on and it will periodically blink.
"M" models.
Flame monitoring is achieved via a thermal sensor which will cut
off gas supply in case of bad combustion or flame blame out.
"A" and "M" models are fitted with an overheat thermostatic cut off
device which will cut off gas supply in case of overheating. This safety
device will automatically return to its initial function as soon as the
heater is cooled off. For that reason it is essential to locate and repair
properly the defect which has led to overheat before making any at-
tempt to re-start the heater.
To re-start the heater, follow instructions as indicated above.
MOVING THE HEATER
Always stop and disconnect heater from mains and gas cylinder
before moving it. Wait till heater is cooled off. The heater can be moved
either by the handle on top of body or by pulling it up and rolling it on
its wheels.
