IMPORTANT: Pipe joint compounds that resist the action of
natural, propane, and butane gases must be used.
Test all connections for leaks by brushing on a soapy water
solution (liquid detergent works well).
!
WARNING
Never test for leaks with a flame!!!
Converting from One Family
of Gas to Another ______________________
!
WARNING (CE Dryers)
This appliance must only be operated with the gas
type indicated on the dryer’s rating plate. If the
appliance is converted (gas type changed), a new
rating plate must be obtained from ADC (dryer’s serial
number is required to purchase a conversion kit).
IMPORTANT: Any burner changes or conversions must be
made by a qualified professional.
The dryers manufactured for Belgium, Luxemburg, Greece,
Estonia, Slovak Republic, Iceland, Malta, Poland and
Cyprus cannot be converted from one family of gas to
another.
Conversion from Natural Gas
to Propane or Butane Gas
The following conversion allows the dryer to be operated with
either propane, butane, or other liquefied petroleum gases.
The use of gas valve kit (P/N 140411) disables the internal
regulator of the gas valve. Therefore, the gas supply is
ungoverned and an external regulator must be provided at
the source of the supply (example propane tank) or the gas
supply line to the dryer. The type of conversion kit supplied
will depend on the country the dryer is installed in.
Parts Required for Conversion:
Description P/N Qty
Unregulated Gas Conversion Kit** 140411 1
OR
Regulated Propane Gas Conversion Kit*** 140413 1
Burner Orifice (Injector) * 1
NON-CE DRYERS ONLY
Propane Gas Conversion Label 112011 1
Propane Conversion Confirmation Label 114083
Propane Conversion Rating Plate Addendum 114090
CE DRYERS ONLY
Rating Plate 114126 1
* Refer to page 23 and page 24 for orifice (injector) size.
** Required for unregulated propane or butane only.
*** Required for regulated propane or other liquefied petroleum gases only.
Instructions
1. Discontinue electrical power to the dryer.
2. Close all shutoff valves in the dryer gas supply line.
3. Disconnect gas valve wiring.
CE dryer connections will be B.S.P.T., all others will be N.P.T.
There should be a minimum 6-inch (15.24 cm) clearance
between the back guard and the first bend in the gas piping
for ease of servicing. It is recommended that a gas shutoff
valve be provided to the gas supply line of each dryer for
ease in servicing.
The size of the main gas supply line (header) will vary
depending on the distance this line travels from the gas meter
or, in the case of propane gas, the supply tank, other gas-
operated appliances on the same line, etc. Specific
information regarding supply line size should be determined
by the gas supplier.
Installer within Australia – refer to AS/NZS5601.1 for guidance
on gas supply pipe sizing required for this appliance
installation.
NOTE: Undersized gas supply piping can create a low or
inconsistent pressure, which will result in erratic operation
of the burner ignition system.
Piping / Connections
Consistent gas pressure is essential at all gas connections.
It is recommended that a 3/4-inch (19.05 mm) pipe gas loop
be installed in the supply line servicing a bank of dryers. An
in-line pressure regulator must be installed in the gas supply
line (header) if the (natural) gas pressure exceeds 13.0 in
WC (32.34 mb) pressure.
