G.  GAS INFORMATION

It is your responsibility to have 

ALL

 plumbing connections made by a qualified professional to assure that the gas

plumbing installation is adequate and conforms to local and state regulations or codes.  In the absence of such
codes, 

ALL

 plumbing connections, materials, and workmanship 

must conform

 to the applicable requirements of

the National Fuel Gas Code ANSI Z223.1-LATEST EDITION, or in Canada, the Canadian Installation Codes
CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST
EDITION.

IMPORTANT:

Failure to comply with codes or ordinances, and/or requirements in this manual, can
result in personal injury and improper operation of the dryer.

The dryer and its individual shutoff valves 

must be

 disconnected from the gas supply piping system during any

pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).  The dryer 

must be

 isolated

from the gas supply piping system by closing its individual manual shutoff valve during any pressure test of the
gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).

IMPORTANT:

Failure to isolate or disconnect the dryer from supply as noted can cause irreparable
damage to the gas valve, which will

 

VOID THE WARRANTY.

WARNING: FIRE OR EXPLOSION COULD RESULT.

1. Gas Supply

The gas dryer installation 

must meet

 the American National Standard...National Fuel Gas Code ANSI

Z223.1-LATEST EDITION, or in Canada, the Canadian Installation Codes CAN/CGA-B149.1 M91 (Natural
Gas) or CAN/CGA-B149.2-M91 (L.P. Gas) or LATEST EDITION, as well as local codes and ordinances
and 

must be

 done by a qualified professional.

NOTE:

Undersized gas piping will result in ignition problems, slow drying, increased use of energy, and
can create a safety hazard.

The dryer 

must be

 connected to the type of heat/gas indicated on the dryer data label affixed to the left

side panel area behind the top control (access) door.  If this information does not agree with the type of gas
available, 

DO NOT operate the dryer.

  

Contact the dealer who sold the dryer or contact the 

Maytag Co.

IMPORTANT:

Any burner changes or conversions 

must be

 

made by a qualified professional.

The input ratings shown on the dryer data label are for elevations up to 2,000 feet (610 meters), unless
elevation requirements of over 2,000 feet (610 meters) 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
(610 meters) is made by changing each burner orifice.  If this conversion is necessary, contact the dealer
who sold the dryer or contact the 

Maytag Co
