Piping/Connections

CE dryer connections will be B.S.P.T., all others will be N.P.T.

There should be a minimum 6-inch (15.24 cm) clearance
between the back guard and the first bend in the gas piping
for ease of servicing. It is recommended that a gas shutoff
valve be provided to the gas supply line of each dryer for ease
in servicing.
The size of the main gas supply line (header) will vary
depending on the distance this line travels from the gas meter
or, in the case of L.P. gas, the supply tank, other gas-operated
appliances on the same line, etc. Specific information
regarding supply line size should be determined by the gas
supplier.

Note

Undersized gas supply piping can create a low or
inconsistent pressure, which will result in erratic

operation of the burner ignition system.

TYPICAL NATURAL GAS INSTALLATION

NOTES ______________________________________________________

_____________________________________________________________

Important

Pipe joint compounds that resist the action of
natural, L.P., and butane gases must be used.

Test all connections for leaks by brushing on a soapy water
solution (liquid detergent works well).

Warning

Never test for leaks with a flame!!!

TYPICAL L.P. GAS INSTALLATION

Consistent gas pressure is essential at all gas connections.
It is recommended that a 3/4-inch (19.05 mm) pipe gas loop
be installed in the supply line servicing a bank of dryers. An
in-line pressure regulator must be installed in the gas supply
line (header) if the (natural) gas pressure exceeds 13.0 in
WC (32.34 mb) pressure.
A plugged tap, accessible for a pressure gauge connection,
must be installed in the main gas supply line immediately
upstream of the dryers.
