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.
Electric Models Only

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 and Australian 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.
