4. Grounding
Grounding (earth) connections 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. 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 at the left side control
cabinet.
For added personal safety, when possible, it is suggested that a separate ground wire (sized
per local codes) be connected from the ground connection of the dryer to a grounded cold water
pipe. Do not ground to a gas or hot water pipe. The grounded cold water pipe must have metal to
metal connections all the way to electrical ground. If there are any non – metallic 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. For proper
operation of the microprocessor (computer), an earth (zero) ground is required.
NOTE: Grounding via metallic electrical conduit (pipe) is not commended.
It is your responsibility to have all plumbing connections made by a qualified professional to
assure that the gas plumbing installation is adequate and conforms with local and state regulations
or codes. In the absence of such codes, all plumbing connections, material, 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
Gas) or CAN/CGA – B149.2 – M91 (L.P. Gas) or LATEST EDITION.
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.
The dryer and its individual shut – off 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). The dryer must be isolated from the gas supply piping system by closing its individual
manual shut-off valve during any pressure testing of the gas supply piping 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 valves VOIDING THE WARRANTY.
WARNING:
FIRE or EXPLOSION COULD RESULT.
