Grounding
A ground (earth) connection must be provided and installed
in accordance with state and local codes. In the absence of
these codes, grounding must conform to applicable
requirements of the National Electrical Code ANSI/NFPA NO.
70-LATEST EDITION, or in Canada, the installation must
conform to applicable Canada Standards: Canadian Electrical
Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION.
The ground connection may be to a proven earth ground at
the location service panel.
Note
A grounding connection (terminal lug) is provided
in the dryer’s electrical service/relay box at the
rear, upper left hand corner of the dryer.
For added personal safety, when possible, it is suggested
that a separate ground wire (size per local codes) be
connected from the ground connection of the dryer to a
grounded cold water pipe. Do not ground to a gas pipe or
hot water pipe. The grounded cold water pipe must have
metal-to-metal connection all the way to the electrical ground.
If there are any nonmetallic interruptions, such as a meter,
pump, plastic, rubber, or other insulating connectors, they
must be jumped out with a wire (size per local codes) and
securely clamped to bare metal at both ends.
Important
For personal safety and proper operation, the
dryer must be grounded. For proper operation of
the microprocessor controller (computer), an earth (zero)
ground is required.
Note
Grounding via metallic electrical conduit (pipe) is
not recommended.
Gas Information _______________________
It is your responsibility to have all plumbing connections made
by a qualified professional to ensure that the gas plumbing
installation is adequate and conforms to local and state
regulations or codes. In the absence of such codes, all
plumbing connections, materials, and workmanship must
conform to the applicable requirements of the National Fuel
Gas Code ANSI Z223.1-LATEST EDITION, or in Canada, the
Canadian Installation Codes CAN/CGA-B149.1-M91 (Natural

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.
The dryer and its individual shutoff valves 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). 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).
Important
Failure to isolate or disconnect dryer from supply
as noted can cause irreparable damage to the gas
valve, which will void the warranty.
Warning
Fire or explosion could result due to failure of
isolating or disconnecting the gas supply as
noted.
Gas Supply
The gas dryer installation must meet the American National
Standard...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/CGA-B149.2-
M91 (L.P. Gas) or LATEST EDITION, as well as local codes
and ordinances and must be done by a qualified professional.
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 dryer label. 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 the manufacturer.
Important
Any burner changes or conversions must be
made by a qualified professional.
The input ratings shown on the dryer data label are for
elevations up to 2,000 feet (609.6 meters), unless elevation
requirements of over 2,000 feet (609.6 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 (609.6 meters) is made by changing each
burner orifice. If this conversion is necessary, contact the
distributor who sold the dryer or the manufacturer.
Important
This gas dryer is not provided with an internal gas
supply shutoff and an external gas supply shutoff
must be provided.
