It is recommended to use gas cylinders of 30 kg providing a thermal power of 30 kW. You are allowed
to use larger gas cylinders if more thermal power is needed.
It is recommended to use gas cylinders with an appropriate capacity to avoid problems due to partial
fuel gasification. The correct pressure (refer to the specification tag on the heater) is indicated by the
included pressure regulator or a similar model.
Make sure the feeding gas hose is in perfect condition. Only use flexible and appropriate models when
replacing the gas hose. Always respect the local regulations. Do not crimp the flexible hose.

Connection to the Mains
Before connecting the heater to the mains, check if the used power supply and frequency match the
specifications on the specification tag. Always respect the local regulations when connecting the heater to the
mains.
Only connect the device to an earthed mains.
Disconnect the device from the mains prior to any maintenance or cleaning activity.
Always make sure that the mains is earthed.
7.
Switching On the Mobile Forced-Air Heater
1.
Open the gas valve.
2.
Flick the switch to position I.
3.
Fully press and hold the gas valve. Operate the igniter several times.
4.
The flame burns. Hold the gas valve pressed for 15 seconds to activate the safety mechanism.
5.
Release the gas valve. The flame will keep burning.
6.
The safety mechanism will automatically switch off the heater in a few seconds in case of an electric power
failure. This mechanism will also switch off the heater in case of a gas shortage. In both cases, follow the
explanation above to switch on the heater again.
7.
Avoid operating the igniter for a prolonged period. Check for problems if the heater does not switch on.
8.
Checking a Switched-On Heater
Check a switched-on heater by observing the pilot flame at the air exit of the heater. Make sure that the pilot
light burns steadily inside the burner.
Be careful when checking the pilot light as the air exiting the heater can be extremely hot. Maintain
yourself at a safe distance.
9.
Switching Off the Heater
1.
Close the gas cylinder.
2.
Close the pressure regulator or disconnect it from the gas cylinder.
3.
Leave the heater to cool down for at least 60 seconds after the pilot light has died out.
4.
Switch off the heater by flicking the switch to the O position.
5.
Disconnect from the mains by pulling the plug.
6.
Disconnect the flexible hose from the heater.
10.
Using the Heater Near Persons or Animals
The forced-air heater can be used in a well-ventilated room where the pollutant percentage does not exceed the
allowed levels.
Sufficient ventilation is guaranteed only when the minimum room volume, in m³, is 30 times the nominal
thermal power (in kW) of all the switched-on devices used in that room, and when the ventilation happens
through doors, windows or other openings which have a minimum total volume, in m³, of 0.003 times the
nominal thermal power (in kW) of all the switched-on devices used in that room.
Do not use the heater to permanently heat stables or other animal housings.
