B. LOCATION REQUIREMENTS Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LATEST EDITION, or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General Installation and Gas Plumbing). -
Page 13: Dryer Enclosure Requirements
C. DRYER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible material. NOTE: Allowances must be made for opening the control door. A 30-inches (76.2 cm) for optimum opening of load door. B The maximum thickness of the bulkhead is 4-inches (10.16 cm). For electric dryers the maximum thickness of the bulkhead is 1-inch (2.54 cm) within 3-inches (7.62 cm) from the top of the control door. -
Page 14: Fresh Air Supply Requirements
D. FRESH AIR SUPPLY REQUIREMENTS The air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An unrestricted source of air is necessary for each dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.14 square meters) is required for each dryer. -
Page 15: Exhaust Requirements
E. EXHAUST REQUIREMENTS Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will create excessive back pressure which results in slow drying, increased use of energy, and shutdown of the burner by the airflow (sail) switch, burner hi-limits, or lint chamber hi-limit protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside. -
Page 16: Single Dryer Venting
NOTE: As per the National Fuel Gas Code, “Exhaust ducts for type 2 clothes dryers shall be constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent in strength and corrosion resistance to ducts made of galvanized sheet steel not less than 0.0195-inches (26 gauge [0.50 mm]) thick.”... -
Page 17: Vertical Venting
VERTICAL VENTING When vertical single 10-inch (25.4 cm) venting is used (refer to Illus. B below), the ductwork from the dryer to the outside outlet cannot exceed 40 feet (12.19 meters). This calculation compensates for the use of a maximum of three (3) elbows including the two (2) elbows creating the 180°... - Page 18 MULTIPLE DRYER (COMMON) VENTING If it is not feasible to provide separate exhaust ducts for each dryer, ducts for individual dryers may be channeled into a common main duct.

Do you have a question about the MDG50MNV and is the answer not in the manual?
Questions and answers
Hi our MDG50MNV WW29 NOT CATHING FIRE
The Maytag MDG50MNV may not be catching fire because the flame is not being detected by the flame sensor during the ignition trial period. If the gas burner flame is not sensed at the end of the ignition period (initial trial and two retries), the DSI (Direct Spark Ignition) module will go into "LOCKOUT" mode, preventing ignition. This could be due to a failure in the flame sensor, issues with the gas supply, or an internal or power failure indicated by no L.E.D. light on the diagnostic indicator.
