Gas requirements (Not applicable to ventless (heat pump) models)
WARNING
• Use only natural or LP (liquid propane) gases.
• The installation must be conformed with local codes, or in the absence of local codes, with the national
fuel gas code, ANSI Z223.1/NFPA 54, latest revision(for the UNITED STATES), or with the natural gas and
propane installation code, CSA B149.1(for Canada).
• Gas dryers are equipped with a burner vent for use with natural gas. If you plan to use your dryer with
LP (liquid propane) gas, it must be converted for safe and proper performance by a qualified service
technician. (LNG models only)
You must check the burner of your model and use the proper LP Kit accordingly. To check the detail
information of the burner, open the door and check the rating label location on the door frame.

line on your dryer. The National Fuel Gas Code requires that an accessible, approved manual gas shut-
off valve be installed within 6" of your dryer.

• Additionally, a

connection, must be installed immediately upstream of your dryer's gas supply connection.
• Your dryer must be disconnected from the gas supply pipe system during any pressure testing of the
system.
• Do not reuse old flexible metal gas lines. Flexible gas lines must be designed and certified by the
standard for connectors for Gas Appliances, ANSI Z21.24 • CSA 6.10.
NOTE
• Your dryer uses an automatic ignition system to ignite the burner. There is no constant burning pilot.
• Any pipe joint compound used must be resistant to the action of any liquefied petroleum gas.
• As a courtesy, most local gas utilities will inspect a gas appliance installation.
Commonwealth of Massachusetts installation instructions
Your dryer must be installed by a licensed plumber or gas fitter. A "T" handle manual gas valve must be
installed in the gas supply line to your dryer. If a flexible gas connector is used to install your dryer, the
connector can be no longer than 3' (36").
WARNING
• Gas leaks may occur in your system, creating a dangerous situation.
• Gas leaks may not be detected by smell alone.
• Gas suppliers recommend you purchase and install a UL-approved gas detector.
• Install and use in accordance with the manufacturer's instructions.
