WARNING

Electrical Shock Hazard

Plug into a grounded 3-prong outlet. Do not remove ground prong.

Do not use an adapter.

Do not use an extension cord.

Failure to follow these instructions can result in death, fire, or electrical shock.

Important: Observe all governing codes and ordinances.

A 120-volt, 60-Hz, AC-only, 15- or 20-ampere fused electrical supply is required. A time-delay fuse or circuit breaker is recommended.

It is recommended that a separate circuit serving only this appliance be provided.

A wiring diagram is located inside the console or on the inside of the lower front panel.

If codes permit and a separate ground wire is used, it is recommended that a qualified electrician determine that the ground path is adequate.

Recommended ground method

The dryer, when installed, must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code ANSI/NFPA 70*.

GROUNDING INSTRUCTIONS: This appliance must be grounded. In the event of malfunction or breakdown, grounding will reduce the risk of electric shock by providing a path of least resistance for electric current.

The power supply cord plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

WARNING - Improper connection of the equipment- grounding conductor can result in a risk of electric shock. Check with a qualified electrician or serviceman if you are in doubt as to whether the appliance is properly grounded. Do not modify the plug provided with the appliance - if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

Gas supply

requirements

WARNING

Explosion Hazard

Use a new AGA or CSA approved gas supply line.

Install a shut-off valve.

Securely tighten all gas connections.

If connected to LP, have a qualified person make sure gas pressure does not exceed 13" water column. Examples of a qualified person include licensed heating personnel, authorized gas company personnel, and authorized service personnel.

Failure to do so can result in death, explosion, or fire.

OBSERVE ALL GOVERNING CODES AND ORDINANCES.

Gas requirements:

Check that dryer is equipped with the correct burner for the particular type of gas in the home. Burner information will be found on the model/serial rating plate in door well of the dryer. If this information does not agree with the type of gas available, see your dealer.

Burner input requirements:

Elevations up to 10,000 feet:

The design of this dryer has been certified by CSA International for use at altitudes up to 10,000 feet above sea level at the B.T.U. rating indicated on the model/serial rating plate. Burner input adjustments are not required when the dryer is operated up to this elevation.

Elevations above 10,000 feet:

When installed above 10,000 feet, a four percent (4%) reduction of the burner B.T.U. rating shown on the model/serial rating plate is required for each 1,000 foot increase in elevation. For assistance installing dryer above 10,000 feet elevation, contact your serving gas supplier.

Supply line requirements:

shutoff valve “open” position

to dryer

rigid gas supply line

Provide a 1/2-inch IPS rigid gas supply line to the dryer location.

A combination of pipe fittings must be used to obtain an in-line connection to the dryer.

When acceptable to the gas supplier and local codes, 3/8-inch approved tubing may be used for lengths under 20 feet. For lengths over 20 feet, larger tubing should be used.

An individual manual shutoff valve must be installed within 6 feet of the dryer in accordance with the National Fuel Gas Code ANSI Z223.1 – latest edition*.

Pipe-joint compounds resistant to the action of L.P. gas must be used.

If local codes permit, it is recommended that new flexible metal tubing, design-certified by AGA or CSA, be used for connecting the appliance to the rigid gas supply line. (The gas pipe which extends through the lower rear of the appliance has 3/8- inch male pipe thread.)

An elbow and connector between tubing and dryer pipe may be needed to prevent kinking.

A 1/8-inch NPT plugged tapping, accessible for test gauge connection, must be installed immediately upstream of the gas supply connection to the dryer.

The gas supply must have a shutoff valve. The valve should be within six feet of the dryer and in the same room. The location should be easy to reach for opening and closing the valve.

The dryer and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi.

Natural Gas:

This dryer is equipped for use with NATURAL GAS. It is design-certified by CSA International for L.P. (propane or butane) gases with appropriate conversion.

The dryer must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2psi.

L.P. Gas:

No attempt shall be made to convert the appliance from the gas specified on the model/serial rating plate for use with a different gas without consulting the serving gas supplier.

Conversion must be done by a qualified service technician. Gas conversion kit part numbers are listed on the gas valve burner base.
