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, 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.

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.

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.

WARNING

FIRE HAZARD

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 dryer.

WARNING

FIRE HAZARD

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.

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.
