Connection to gas (only gas models)

The dryers have an inlet at 1/2". All the gas models are designed to work with propane gas (LPG)
or natural gas (see the appliance's specifications plate).
Note: The dryer is configured to operate with a burner pressure and gas in accordance with the
one that is indicated on the specifications plate. Check that the type of gas and pressure value in
the burner correspond to the specifications plate. If not, consult the supplier.
Do not connect a tube with an inner diameter less than that required for the machine.
Install a pressure regulator (only for LPG), a manual valve and a gas filter in front of the machine.
Make sure that the dirt does not enter the valve during connection.
Carry out a drip test with soapy water or a special product designed for this to check the water
tightness of the assembly.
For LPG propane gas (G31) regulator with 37 mbar of supply pressure and 4 kg/h of minimum
flow.
For natural gas (G20) without regulator, directly connect to the line (20 mbar) and install a manual
valve.
The dryer can be delivered from origin with 4.2 mm injectors regulated at a burner pressure of 8
mbar to operate with natural gas or delivered with 2.3 mm injectors regulated at a pressure of
28.8 mbar to operate with propane gas.
The dryer has spare injectors and a new specifications plate if installing the appliance to operate
with a different group of gas were to be necessary, allowing installing the machine in many
countries with the main fuels.
In the following table you can consult for each type of gas and in different countries the diameter
of the injector and burner pressure adequate for operating correctly.
