Caution

!The dryer must be grounded. A ground lug has been provided for this purpose.

Input connection wiring must be sized properly to handle the dryer’s current draw. This information is printed on the dryer’s data label.

Important

Gas Information _______________________

It is your responsibility to have all plumbing connections, materials, and workmanship conform to local and state regulations or codes of the country of destination. In the absence of such codes, all plumbing connections, materials, and workmanship must conform to the applicable local requirements. In the USA this is 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/CGAB149.2-M91 (L.P. Gas) or LATEST EDITION.

In Australia, the fuel gas code is AS 5601/AG 601, local authority, gas, electricity, and any other relevant statutory regulations.

It is important that gas pressure regulators meet applicable pressure requirements, and that gas meters be rated for the total amount of all the appliance Btu being supplied.

Important

!Failure to comply with these codes or ordinances, and/or the requirements stipulated in this manual,

can result in personal injury and improper operation of the dryer.

Important

!For ease of service, the individual gas supply line of each dryer must have its own manual shutoff

valve.

The dryer and its individual shutoff valve 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) for non-CE dryers or 50 mb for CE dryers.

Failure to isolate or disconnect the dryer from supply as noted can cause irreparable damage to the gas valve, voiding the warranty.

Note

!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 system at test pressures equal to or less than 1/2 psig (3.5 kPa) for non-CE dryers or 50 mb for CE dryers.

Warning

!Fire or explosion could result due to failure of isolating or disconnecting the gas supply as noted.

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 data label and pressure must be confirmed. If this information does not agree with the type of gas available, do not operate the dryer. Contact the distributor who sold the dryer or contact the manufacturer.

The input ratings shown on the 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 distributor who sold the dryer or contact the manufacturer.

Important

!If connection to this appliance is made with a flexible hose, it must be suitable for the appliance

category in accordance with national installation regulations of the country of destination, and if in doubt the installer must contact the supplier. The manufacturer of this appliance does not recommend the use of flexible gas supply line/hose. An external gas supply shutoff must be provided.

CE Dryers

There is an N.P.T. to B.S.P.T. adaptor included with each dryer, which must be installed to the gas inlet. The adaptor is shipped in the tumbler.

Important

!Pipe joint compounds that resist the action of natural, propane, and butane gases must be used.
