The input ratings shown on the dryer data label are for elevations up to 2,000 feet, unless elevation
requirements of over 2,000 feet were specified at the time the dryer order was placed with the factory.
The adjustment or conversion of dryers in the field for elevations over 2,000 feet are made by changing
each burner orifice. If this conversion is necessary, contact the distributor who sold the dryer or contact
the Maytag.

Technical Gas Data
a.
Gas Specifications
* Measured at gas valve pressure tap when the gas valve is on.
** For elevations up to 2,000 feet.
W.C. = Water Column in inches.
N.P.T. = National Pipe Thread.
b.
Natural Gas
Regulation is controlled by each gas valve's internal regulator. Incoming supply pressure must be
consistent between a minimum of 6.0 inches and a maximum of 12.0 inches water column pressure.
c. Liquid Propane (L.P.) Gas
Dryers made for use with L.P. gas have the gas valve's internal pressure regulator blocked open so that
the gas pressure must be regulated upstream of the dryer. The pressure measured at each gas valve
pressure tap must be a consistent 10.5 inches water column. There is no regulator or regulation
provided in an L.P. dryer. The water column pressure must be regulated at the source (L.P. tank) or an
external regulator must be added to each dryer.
3.
Piping Connections
ALL components / materials must conform to National Fuel Gas Code specifications, or in CANADA, the
Canadian Installation Codes (for General Installation and Gas Plumbing).
It is important that the gas pressure regulators meet applicable pressure requirements and that gas meters
be rated for the total amount of
ALL the appliance Btu's being supplied.
