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

aconversion 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.

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.

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.

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.
