Piping / Connections
The dryer is provided with two 1/2” N.P.T. (3/8” B.S.P.T. for CE
and Australian dryers) inlet pipe connections (1 for each
tumbler) at the rear of the dryer. If a separate feed is provided
for each tumbler from the main supply line (header), then a
1/2” (12.7 mm) line connection is sufficient. However, if the
top and bottom tumbler connections are connected together,
the supply from the header must be increased to 3/4-inch
(19.05 mm). 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.
Installer within Australia – refer to AS/NZS5601.1 for
guidance on gas supply pipe sizing required for this
appliance installation.
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 propane 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, propane, 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!!!
