Piping / Connections
Inlet connection is 3/8" N.P.T.
CE and Australian 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.

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.
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).
Never test for leaks with a flame!!!
Converting from One Family
of Gas to Another _____________________
WARNING
!
This appliance must only be operated with the gas
type indicated on the dryer's data plate. If the
appliance is converted (gas type changed), a data
plate amendment must be obtained from American
Dryer Corporation (dryer's serial number is required
to purchase a conversion kit).
IMPORTANT: Any burner changes or conversions must be
made by a qualified professional.
The dryers manufactured for Belgium, Luxemburg, Greece,
Estonia, Slovak Republic, Iceland, Malta, Poland and
Cyprus cannot be converted from one family of gas to
another.
