Whirlpool 8535845 Natural Gas, Burner input requirements, Supply line requirements

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.

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.

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:

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

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*.

Recommended gas line connection method.

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.)

Optional gas line connection method.

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.

A combination of pipe fittings must be used to connect the dryer to the gas line.

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

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 dryer 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.

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