Unregulated Gas Valve
Regulate (govern) gas externally (refer to “Supply Pressure”
in chart on page
14) to the correct gas pressure for the gas
being used. Operate dryer through one complete cycle to
ensure proper operation.
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
14. The supply pressure must also match
14 for the type of gas to be used.
IMPORTANT:
Conversions done improperly can result in
a fire or explosion!
Conversion from Propane
or Butane Gas to Natural Gas
The following conversion allows the dryer to be operated
with natural gas.
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.
Repeat these steps for the other burner.
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.

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, 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 an 11/16” 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 three 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 (ADC 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 (ADC P/N 140415).
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.
Repeat these steps for the other burner.
Open all shutoff valves, reconnect electrical power to the
dryer, and test for leaks.
Operate the dryer through one complete cycle to ensure
proper operation.
With dryer operating, check the manifold (burner) pressure
at the tap on the gas valve to ensure proper operating
pressure (refer to chart on page
