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.
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 reseller 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 reseller 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.
