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 data plate. If the
appliance is converted (gas type changed), a data
plate amendment must be obtained from American
Dryer Corporation (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 LPG. The use of gas valve
kit (ADC P/N 140414) 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 L.P. tank) or the gas supply line to the dryer.
The type of L.P. kit supplied will depend on the country the
dryer is installed in.
Parts Required for Conversion:
Description ADC P/N Qty
Unregulated Gas Conversion Kit** 140414 ***
OR
Regulated L.P. Gas Conversion Kit**** 140416 ***
Burner Orifice (Injector) * ***
L.P. Conversion Label 114515 1
* Refer to page 21 for orifice (injector) size.
** Required for unregulated propane or butane only.
*** SL20 and SL30 will require 1; SL50 and SL75 will require 2.
**** Required for regulated LPG or propane only.
Instructions
Disconnect electrical power to the dryer.
Close all shutoff valves in dryer’s gas supply line.
IMPORTANT: The SL50 and SL75 will require that the
following procedures be performed on both burner
assemblies.
Open the panel located just below the loading door.
Locate the gas train and disconnect the union, three electrical
plugs, and the gas train mounting screws from the burner.
Carefully slide the gas train out of the gas train enclosure.
(The carbon ignitor located at the far end of the gas train is
very fragile.)
Remove two burner tube mounting screws and remove
burner tube in order to gain access to the orifice.
Using a 3/8” wrench or socket, remove the existing orifice
and replace it with an orifice from the kit.
Unregulated Gas Valve
Regulate (govern) gas externally (refer to “Supply Pressure”
in chart on page 21) to the correct gas pressure for the gas
being used. Operate dryer through one complete cycle to
ensure proper operation.
IMPORTANT: Use extreme care when removing and
replacing orifice (injector). This orifice (injector) is made
of brass, which is easily damaged.
Reinstall the burner tube onto the burner base.
Use a flat screwdriver to remove the regulator vent cap.
• For unregulated L.P. gas (most countries): install
blocking pin (ADC P/N 140414).
• For regulated L.P. gas (some countries): remove the
white plastic regulator adjustment screw (under vent
cap). Remove spring under screw and replace with
spring from kit (ADC P/N 140416). Replace regulator
adjustment screw.
Install the gas train back into the dryer gas train enclosure.
Be sure the tab at the rear of the gas train engages into the
mounting slot.
Connect the union and the three electrical plugs.
Affix L.P. Conversion Label (ADC P/N 114515) to the dryer’s
data label.
Complete L.P. Kit Conversion Confirmation Label (ADC P/N
114083) and affix this label as close as possible to the
dryer’s existing dryer rating (data) label/plate.
Non-CE Dryers
Affix L.P. Conversion Rating Label Addendum (ADC P/N
114090) as close as possible to the dryer’s existing dryer
rating (data) label/plate.
CE Dryers
Affix new data plate label that came with the conversion kit.
Open all shutoff valves, reconnect electrical power to the
dryer, and test for leaks.
IMPORTANT: Never test for leaks with an open flame!!!
Use a soapy water solution or product intended for that
purpose.
