Gas Supply Requirements

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 (1.27cm)
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.
IMPORTANT
The supply line must be equipped with an approved
manual shutoff valve. This valve should be located in
the same room as the dryer and should be in a
location that allows ease of opening and closing. Do
not block access to the gas shutoff valve.

Gas Connection

1. Remove shipping cap from gas pipe at rear of dryer.
IMPORTANT
DO NOT connect the dryer to L.P. gas service without
converting the gas valve. An L.P. conversion kit must
be installed by a qualified gas technician.

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 2-13)
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.
WARNING
EXPLOSION HAZARD
NEVER test for gas leaks with an open flame.
