Gas supply requirements

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, flexible 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.

Exhaust system requirements

Use only 4 inch (10.2 cm) diameter (minimum) rigid
or flexible 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.
Failure to follow these instructions can create
excessive drying times and fire hazards.
The following are specific requirements
for proper and safe operation of your
Do not install a clothes dryer with flexible 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 airflow and increase the
risk of fire.
Installation Requirements
4. The gas supply line MUST have an individual
shutoff valve.
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.
If your present system is made up of plastic
duct or metal foil duct, replace it with a rigid or
semi-rigid metal duct. In Canada and the United
States if metal (foil type) duct is installed, it must
be of a specific type identified by the appliance
manufacturer as suitable for use with clothes
dryers and in the United States must also comply
with the Outline for Clothes Dryer Transition Duct,
UL standard 2158A. Also, ensure the present duct
is free of any lint prior to installing dryer duct.
