1. Remove the shipping cap from gas pipe at the
rear of the dryer.
2. Connect a 1/2 inch (1.27 cm) I.D. semi-rigid or
approved pipe from gas supply line to the 3/8
inch (0.96 cm) pipe located on the back of the
dryer. Use a 1/2 inch to 3/8 inch (1.27 cm to
0.96 cm) reducer for the connection. Apply an
approved thread sealer that is resistant to the
corrosive action of liquefied gases on all pipe
connections. (See Figure 2-12)
3. Open the shutoff valve in the gas supply line to
allow gas to flow through the pipe. Wait a few
minutes for gas to move through the gas line.
4. Check for gas system leaks with a manometer.
If a manometer is not available, test all
connections by brushing on a soapy water
solution.

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
(1.27cm) 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.
