Dryer Exhaust - Dexter Laundry B-Series Operator's Manual

components are helped to have a longer useful life when they are supplied with the clean stable electrical power
they like.
We are including the following names and phone numbers of a few suppliers of these devices for those who don't
currently have a source.

5. 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.
The inlet gas connection to the unit is 1/2 inch pipe thread.
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 should be provided in the gas piping entering the unit 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 de-rate 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.
6. EXHAUST INSTALLATION. Exhausting of the dryer(s) 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 exhausted 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 14 ft. (4.25 m) of straight
8 in. diameter pipe with two right angle elbows be used for each cylinder.
Maintain minimum 1" (25) clearance between duct and combustible material.
If the exhaust pipe passes through a wall, a metal sleeve of slightly larger diameter should be set in the wall and
the exhaust pipe passed through this sleeve. This practice is required by some local codes and is recommended in
all cases to protect the wall. This type of installation should have a means provided to prevent rain and high winds
from entering the exhaust when the dryer is not in use. A hood with a hinged damper can be used for this purpose.
