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
4.The gas supply line MUST have an individual shutoff valve installed in accordance with the
B149.1, Natural Gas and Propane Installation Code.
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.
