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 JLA Limited (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 (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 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 (for both top and bottom tumbler) in
dryer’s gas supply line.
Important
The following procedures must be performed on
both top and bottom tumblers.
Open the panels located just below each 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 17) 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 (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 (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.
Repeat these steps for the other burner.
Affix L.P. Conversion Label (P/N 114515) to the dryer’s data
label.
Complete L.P. Kit Conversion Confirmation Label (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 (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.
