Piping/Connections
The dryer is provided with two 1/2" N.P.T. (3/8" B.S.P.T. for
CE dryers) inlet pipe connections (1 for each tumbler) at the
rear of the dryer. If a separate feed is provided for each
tumbler from the main supply line (header), then a 1/2" (12.7
mm) line connection is sufficient. However, if the top and
bottom tumbler connections are connected together, the
supply from the header must be increased to 3/4-inch (19.05
mm). There should be a minimum 6-inch (15.24 cm)
clearance between the back guard and the first bend in the
gas piping for ease of servicing. It is recommended that a
gas shutoff valve be provided to the gas supply line of each
dryer for ease in servicing.
The size of the main gas supply line (header) will vary
depending on the distance this line travels from the gas meter
or, in the case of L.P. gas, the supply tank, other gas-operated
appliances on the same line, etc. Specific information
regarding supply line size should be determined by the gas
supplier.
NOTE: Undersized gas supply piping can create a low or
inconsistent pressure, which will result in erratic operation
of the burner ignition system.
TYPICAL NATURAL GAS INSTALLATION
TYPICAL L.P. GAS INSTALLATION
Consistent gas pressure is essential at all gas connections.
It is recommended that a 3/4-inch (19.05 mm) pipe gas loop
be installed in the supply line servicing a bank of dryers. An
in-line pressure regulator must be installed in the gas supply
line (header) if the (natural) gas pressure exceeds 13.0 in
WC (32.34 mb) pressure.
A plugged tap, accessible for a pressure gauge connection,
must be installed in the main gas supply line immediately
upstream of the dryers.

IMPORTANT: Pipe joint compounds that resist the action
of natural, L.P., and butane gases must be used.
Test all connections for leaks by brushing on a soapy
water solution (liquid detergent works well).
!
Never test for leaks with a flame!!!
Converting from One Family
of Gas to Another ______________________
WARNING
!
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.
(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 gas or butane gas (regulated or unregulated).
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.
Parts Required for Conversion:
Description
Unregulated Gas Conversion Kit***
Burner Orifice (Injector)
L.P. Conversion Label
*
This includes one for each pocket/tumbler.
** Refer to page 14 for orifice (injector) size.
*** Required for unregulated propane or butane only.
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.)
