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 19 for orifice (injector) size.
** Required for unregulated propane or butane only.
*** M31SL will require 1; M50SL and M75SL 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 M50SL and M75SL 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, 3 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 2 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 19) to the correct gas pressure for the gas
being used. Operate dryer through 1 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 3 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.
