GAS REQUIREMENTS

The complete gas requirements necessary to operate the dryer satisfactorily are
listed on the serial plate located on the back panel of the dryer and in the specifications section of this
manual. The inlet gas connection to the unit is 1/2-inch pipe thread for T-30 and T-50 and 3/4-inch for
T-80. However, the size of the piping to supply the dryer should be determined by reference to the Na-
tional Fuel Gas Code ANSI Z223.1A and consultation with the local gas supplier. An individual gas shutoff
valve is recommended for each dryer and may be required by local code (not supplied). A joint compound
resistant to the action of liquefied petroleum gases should be employed in making pipe connections. A 1/8-
inch NPT plugged tapping, accessible for test gage connection, must be installed immediately upstream of
the gas supply connection to the dryer. A drip tee is provided in the unit gas piping to catch dirt and other
foreign articles. All pipe connections should be checked for leakage with soap solution. Never check with
an open flame. For altitudes above 2,000 feet (610m), it is necessary to derate the BTU input. Contact
your local distributor for instructions. L.P. gas conversion kits are available for this dryer. Contact your local
distributor.
CAUTION: The dryer must be disconnected from the gas supply piping system during any pressure
testing of that system. Do not expose the dryer's gas control valve to testing pressure.
Burner Set-Up
All gas burner manifolds should be checked for proper gas pressure while burning. Dryer manafold
pressure should be set at 3.5 W.C. for Natural Gas while burner operating.

EXHAUST INSTALLATION.

should be planned and constructed so that no air restrictions occur. Any restriction due to pipe size or type
of installation can cause slow drying time, excessive heat, and lint in the room.
From an operational standpoint, incorrect or inadequate exhausting can cause a cycling of the
high limit thermostat which shuts off the main burners and results in inefficient drying.
Individual exhausting of the dryers is recommended. All heat, moisture, and lint should be ex-
hausted outside by attaching a pipe of the proper diameter to the dryer adapter collar and extending it out
through an outside wall.
This pipe must be very smooth on the inside, as rough surfaces tend to collect lint which will
eventually clog the duct and prevent the dryer from exhausting properly. All elbows must be smooth on
the inside. All joints must be made so the exhaust end of one pipe is inside the next one downstream. The
addition of an exhaust pipe tends to reduce the amount of air the blower can exhaust. This does not affect
the dryer operation if held within practical limits. For the most efficient operation, it is recommended that
no more than 20' (6m) of straight 8" diameter pipe be used with two right angle elbows. When more than
two elbows are used, 2' (600mm) of straight pipe should be removed for each additional elbow. No more
than four right angle elbows should be used to exhaust a dryer.
Maintain minimum 1" (25) clearance between duct and combustible material.
