Installing Gas Drying Tumblers in 
the European Union (EU)
General Information
This information is to be used when installing gas 
tumblers in countries, and/or on gases, different than 
the machine’s factory configuration. Tumblers are 
supplied from the factory for operation on Natural Gas 
or L.P. Gas in the countries of GB/IE/PT/ES/IT. To 
install machines in any other country or on any other 
gas requires some level of modification.
Orifices, stickers, block-open kits, regulator springs 
and other parts needed for gas conversions are to be 
ordered separately.
Models are built in three different configurations:
Regulated Natural Gas – Injector is sized for 
Natural Gas, second family, group H (E) at 
20 mbar inlet pressure. Regulator/governor is 
operational. Gas valve CAN be field converted to 
a non-regulating type.
Unregulated Natural Gas – Injector is sized for 
Natural Gas, second family, group E+ at 
20.25 mbar inlet pressure. Regulator/governor is 
blocked open. Gas valve CANNOT be field-
converted to a regulating type.
Unregulated L.P. (Liquified Petroleum) Gas – 
Injector is sized for L.P. Gas, third family, group 
3+ at 28.37 mbar inlet pressure. Regulator/
governor is blocked open. Gas valve CANNOT 
be field-converted to a regulating type.
Serial plates supplied from the factory are configured 
for the countries of GB/IE/PT/ES/IT. These 
instructions pertain to the situations when the country 
of use or gas supply is different than that on the serial 
plate.
The tables describe the different gases that are 
available in different EU countries, and how the 
machines need to be configured to operate with those 
gases. In the EU, there are Natural Gas configurations 
that do not allow for machine regulation, and L.P. Gas 
configurations that must be regulated. For L.P. Gas, 
third family B/P at 50 mbar, order Regulated Natural 
Gas machines and convert according to Table 2 or 
Table 3.
WARNING
To reduce the risk of electric shock, fire, 
explosion, serious injury or death:
• Disconnect electric power to the 
tumbler before servicing.
• Close gas shut-off valve to gas tumbler 
before servicing.
• Close steam valve to steam tumbler 
before servicing.
• Never start the tumbler with any guards/
panels removed.
• Whenever ground wires are removed 
during servicing, these ground wires 
must be reconnected to ensure that the 
tumbler is properly grounded.
