Unregulated Gas Valve
Regulate (govern) gas externally (refer to “Supply Pressure”
in chart on
page 15
) to the correct gas pressure for the gas
being used. Operate dryer through one complete cycle to
ensure proper operation.
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.
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.
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.
Regulated Gas Valve
Refer to “Gas Pressure Adjustment” on the following page to
adjust the gas valve to the appropriate burner pressure listed
on
page 15
. The supply pressure must also match what is
listed on
page 15
for the type of gas to be used.
IMPORTANT:
Conversions done improperly can result in a
fire or explosion!

Instructions
Disconnect electrical power to the dryer.
Close all shutoff valves in dryer’s gas supply line.
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.
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.
Select from the following 3 options, the conversion to be
performed:
•
Converting from unregulated L.P. to regulated
natural gas:
use a flat screwdriver to remove the cap
with blocking pin and install the regulator vent cap from
the kit (P/N 140415).
•
Converting from unregulated L.P. to unregulated
natural gas:
no change to the regulator is required.
•
Converting from regulated L.P. to regulated natural
gas:
remove the white plastic regulator adjustment
screw (under vent cap). Remove spring under screw
and replace with spring from kit (P/N 140415). Replace
regulator adjustment screw.
Install the gas train back into the dryer gas train enclosure.
