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.
For added personal safety, when possible, it is suggested
that a separate ground wire (no. 18 minimum) 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 no. 4 copper wire and securely clamped to bare
metal at both ends.
Important
For personal safety and proper operation, the dryer
must be grounded.
Provisions are made for ground connection in each dryer at
the electrical service connection area.
Note
An individual manual shutoff valve must be installed
within 6 feet (1.8288 meters) of the dryer in
accordance with the National Fuel Gas Code, ANSI
Z223.1/NFPA 54.
