Regulated Gas Valve
Refer to “Gas Pressure Adjustment” on this page to adjust
the gas valve to the appropriate burner pressure listed on
page
14. The supply pressure must also match what is listed
on page
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.
Parts Required for Conversion:
Description
ADC P/N
Qty
Vent Cap and Spring

2*
Burner Orifice (Injector)
**
2*
* This includes one for each pocket (tumbler).
** Refer to page
14 for orifice (injector) size.
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 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 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
14).
Gas Pressure Adjustment
Disconnect electrical power to the dryer.
IMPORTANT:
The following procedures must be performed
on both top and bottom tumblers.
To adjust gas valve’s internal regulator, remove the regulator
vent cap with the regulator adjustment tool, which is located
on the back guard between the gas inlet and exhaust outlet
(refer to the illustration below for proper use of adjustment
tool). Be sure to use one of the wide ends of the adjustment
tool for removal of the vent cap. Once vent cap is removed,
the narrow end of the adjustment tool can be used to turn the
plastic adjustment screw in the valve. Turn the screw
clockwise to raise pressure and counterclockwise to lower
pressure.
Gas (burner) pressures are measured with the burner in
operation for all burner adjustment conditions. Therefore
once the necessary adjustments have been made, the dryer
must be operated in a heating cycle to verify that the pressure
is correct. If it is not correct, you must discontinue the power
to the unit and make further adjustments. Repeat these steps
as many times as necessary to achieve the correct burner
pressure. Once the adjustment of the valve is complete, the
vent cap must be replaced and sealed with, for example,
paint to prevent maladjustment by the user.

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.
Conversions done improperly can result in a fire or
explosion!
