In installations where the exhaust system is not described in the
charts, the following method must be used to determine if the
exhaust system is acceptable:
1.

Connect an inclined or digital manometer between the
dryer and the point the exhaust connects to the dryer.

2.

Set the dryer timer and temperature to air fluff (cool
down) and start the dryer.

3.

Read the measurement on the manometer.

4.

The system back pressure MUST NOT be higher than
0.75 inches of water column.

If the system back pressure is less than 0.75 inches of water
column, the system is acceptable. If the manometer reading is
higher than 0.75 inches of water column, the system is too
restrictive and the installation is unacceptable.
Although vertical orientation of the exhaust system is
acceptable, certain extenuating circumstances could affect the
performance of the dryer:

Only the rigid metal duct work should be used.

Venting vertical through a roof may expose the exhaust
system to down drafts causing an increase in vent
restriction.

Running the exhaust system through an uninsulated area
may cause condensation and faster accumulation of lint.

Compression or crimping of the exhaust system will cause
an increase in vent restriction.

The exhaust system should be inspected and cleaned a
minimum of every 6 months with normal usage. The more the
dryer is used, the more often you should check the
exhaust system and vent hood for proper operation.

EXHAUST DIRECTION

All dryers shipped from the factory are set up for rear exhausting.
However, on electric dryers, exhausting can be to the right or left
side of the cabinet or the bottom of the dryer. On gas dryers
exhausting can be to the right side of the cabinet or the bottom
of the dryer. Directional exhausting can be accomplished by
installing Exhaust Kit, P/N 131456800, available through your
parts distributor. Follow the instructions supplied with the kit.

EXHAUST DUCT LOCATING DIMENSIONS

GAS SUPPLY REQUIREMENTS

Replace copper connecting pipe that is not

plastic-coated. Stainless steel or plastic-coated brass MUST
be used.
Note: See rough-in dimensions on the following page
(Figure 1).
1. Installation MUST conform with local codes, or in the absence

of local codes, with the National Fuel Gas Code, ANSI Z223.1
(latest edition).

2. The gas supply line should be of 1/2 inch (1.27 cm) pipe.
3. If codes allow, flexible metal tubing may be used to connect

your dryer to the gas supply line. The tubing MUST be
constructed of stainless steel or plastic-coated brass.

4. The gas supply line MUST have an individual shutoff valve.
5. A 1/8 inch (0.32 cm) N.P.T. plugged tapping, accessible for

test gauge connection, MUST be installed immediately
upstream of the gas supply connection to the dryer.

6. The dryer MUST be disconnected from the gas supply piping

system during any pressure testing of the gas supply piping
system at test pressures in excess of 1/2 psig (3.45 kPa).

7. The dryer MUST be isolated from the gas supply piping system

during any pressure testing of the gas supply piping system
at test pressures equal to or less than 1/2 psig (3.45 kPa).

Do not screen the exhaust ends of the vent system,

nor use any screws, rivets or other fastening means that
extend into the duct and catch lint to assemble the exhaust
system.
Lint can become caught in the screen, on the screws or
rivets, clogging the duct work and creating a fire hazard as well
as increasing drying times. Use an approved vent hood to
terminate the duct outdoors, and seal all joints with duct tape.
All male duct pipe fittings MUST be installed downstream with
the flow of air.

Explosion hazard. Do not install the dryer where

gasoline or other flammables are kept or stored. If the dryer is
installed in a garage, it must be a minimum of 18 inches (45.7
cm) above the floor. Failure to do so can result in death, explosion,
fire or burns.
