Gas supply requirements
WARNING
EXPLOSION HAZARD
Uncoated copper tubing will corrode when
subjected to natural gas, causing gas leaks.
Use ONLY black iron, stainless steel, or plastic-
coated brass piping for gas supply.
1. Installation MUST conform with local codes,
or in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1 (latest
edition).
2. The gas supply line should be 1/2 inch (1.27
cm) pipe.
3. If codes allow, fl exible metal tubing may be
used to connect your dryer to the gas supply
line. The tubing MUST be constructed of
stainless steel or plastic-coated brass.
4. The gas supply line MUST have an individual
shutoff valve installed in accordance with the
B149.1, Natural Gas and Propane Installation
Code.
Exhaust system requirements
Use only 4 inch (102 mm) diameter (minimum)
rigid or fl exible metal duct and approved vent
hood which has a swing-out damper(s) that
open when the dryer is in operation. When the
dryer stops, the dampers automatically close to
prevent drafts and the entrance of insects and
rodents. To avoid restricting the outlet, maintain
a minimum of 12 inches (30.5 cm) clearance
between the vent hood and the ground or any
other obstruction.
WARNING
FIRE HAZARD
Failure to follow these instructions can create
excessive drying times and fi re hazards.
The following are specifi c requirements
for proper and safe operation of your
dryer.
WARNING
FIRE HAZARD
Do not install a clothes dryer with fl exible
plastic or metal foil venting materials. Flexible
venting materials are known to collapse, be
easily crushed and trap lint. These conditions
will obstruct clothes dryer airfl ow and increase
the risk of fi re.
If your present system is made up of plastic duct
or metal foil duct, replace it with a rigid or semi-
rigid metal duct. Also, ensure the present duct is
free of any lint prior to installing dryer duct.
Installation Requirements
5. A 1/8 inch (0.32 cm) N.P.T. plugged tapping,
accessible for test gauge connection, MUST
be installed immediately upstream of the gas
supply connection to the dryer.
6. The dryer MUST be disconnected from the
gas supply piping system during any pressure
testing of the gas supply piping system at test
pressures in excess of 1/2 psig (3.45 kPa).
7. The dryer MUST be isolated from the gas
supply piping system during any pressure
testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.45
kPa).
8. Connections for the gas supply must comply
with the Standard for Connectors for Gas
Appliances, ANSI Z21.24/CSA 6.10.
