Piping / Connections
Inlet connection is 3/8” 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.

Heat Input / Gas Consumption/Orifice (Injector) Data
Shaded areas are stated in metric equivalents
* Gas valve’s internal regulator disabled.
** Consult factory for elevations over 2,000 feet (610 meters) for correct orifice size.
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).
!
WARNING
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 the
manufacturer (dryer’s serial number is required to
purchase a conversion kit).
IMPORTANT:
Any burner changes or conversions must be
made by a qualified professional.
Conversion from Natural Gas
to Propane or Butane Gas
The following conversion allows the dryer to be operated with
either propane, butane, or LPG. The use of gas valve kit
(P/N 140414) disables the internal regulator of the gas valve.
Therefore, the gas supply is ungoverned and an external
regulator must be provided at the source of the supply
(example L.P. tank) or the gas supply line to the dryer. The
type of L.P. kit supplied will depend on the country the dryer
is installed in.
