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.
WARNING
● Failure to follow safety warnings exactly could result in
serious injury, death, or property damage.
● Do not install a booster fan in dryer exhaust duct.
● Install all clothes dryers in accordance with the
installation instructions in this manual.
