Conversion from Propane or Butane Gas
to Natural Gas
The following conversion allows the dryer to be operated with
natural gas. If the dryer is setup for unregulated gas, a slight
modification has to be done to the gas valve, to enable the
internal regulator.
Parts Required for Conversion:
Description P/N Qty
Vent Cap 140415 2*
Burner Orifice (Injector) ** 2*
* This includes 1 for each pocket (tumbler).
** Refer to page 17 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, 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.
If converting from unregulated gas, use a flat screwdriver,
remove the cap with blocking pin and install the regulator
vent cap from the kit.
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.
Open all shutoff valves, reconnect electrical power to the dryer,
and test for leaks.
Operate the dryer through 1 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 17).
Gas Pressure Adjustment
Disconnect electrical power to the dryer.
To adjust gas valve’s internal regulator, remove the regulator
cover screw 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 1 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, it
must be sealed to prevent maladjustment by the user with,
for example, paint.
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 Maytag Co.
Conversions done improperly can result in a fire or
explosion!
