Maytag MC2 - Manual (Page 16)

The dryer must be connected to the type of heat/gas indicated on the dryer data label located on the
inside of the control door. If this information does not agree with the type of gas available, contact the
distributor who sold the dryer or the manufacturer.
NOTE: Any burner changes or conversions must be made by a qualified technician.
The gas 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 distributor. The adjustment for dryers in the field for elevations over 2,000 feet are made by
changing the burner orifices. If this adjustment is necessary, contact the distributor who sold the
dryer.
NOTE: Any burner changes or conversions wiiii Ae made by a qualified technician.
2. Technical Gas Data
a. Natural Gas
The natural gas supply pressure to the dryer must be between six (6) and 11 inches water column.
If the pressure is too low, ignition failure and/or slow drying times may result. Excessively high
supply pressure will result in erratic operation of the gas valve's internal pressure regulator. The
pressure measured at the pressure tap on the body of the gas valve must be four (4) inches water
column. This will make the manifold pressure 3-1/2 inches water column.
b. Liquid Propane (L.P.) Gas
Dryers made for use with L.P. gas have the gas valve pressure regulators blocked open so that the
gas pressure must be regulated upstream of the dryer. The pressure measured at the gas
valve body pressure tap must be 11 inches water column. This will make the manifold pressure 10
inches water column.
3. Piping Connections
The dryer is provided with a 1/2" N.P.T. models (3/4" N.P.T. for 75 and 100 lb. models) inlet pipe
connection extending out the rear area or through the top of the dryer. For ease of servicing, the gas
supply line of each dryer should have its own shut-off valve.
The size of the main gas supply line (header) will vary depending on the distance this supply line
travels from the gas meter or in the case of L.P. gas, the supply tank), the amount of tees, other gas
operated appliances, 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.
