Upon delivery, visually inspect the crate, carton and
parts for any visible shipping damage. If the crate,
carton, or cover is damaged or signs of possible
damage are evident, have the carrier note the condition
on the shipping papers before the shipping receipt is
signed, or advise the carrier of the condition as soon as
it is discovered.
Remove the crate and protective cover as soon as
possible and check the items listed on the packing list.
Advise the carrier of any damaged or missing articles
as soon as possible. A written claim should be filed
with the carrier immediately if articles are damaged or
missing.
IMPORTANT: Warranty is void unless tumbler is
installed according to instructions in this manual.
Installation should comply with minimum
specifications and requirements detailed herein,
and with applicable local gas fitting regulations,
municipal building codes, water supply regulations,
electrical wiring regulations, and any other
relevant statutory regulations. Due to varied
requirements, applicable local codes should be
thoroughly understood and all pre-installation
work arranged for accordingly.
To reduce the risk of severe injury, clearance of tumble dryer cabinet from combustible
construction must conform to the minimum clearances.

A drying tumble dryer produces
combustible lint. To reduce the risk of
fire, the tumble dryer must be exhausted
to the outdoors.
W057R1
To reduce the risk of fire and
accumulation of combustible gases, DO
NOT exhaust tumble dryer air into a
window well, gas vent, chimney or
enclosed, unventilated area such as an
attic wall, ceiling, crawl space under a
building, or concealed space of a
building.
W059R1
WARNING
To reduce the risk of fire due to increased
static pressure, we do not recommend
installation of in-line secondary lint filters
or lint collectors. If secondary systems
are mandated, frequently clean the
system to assure safe operation.
W749
WARNING
Improperly sized or assembled ductwork
causes excess back pressure which
results in slow drying, lint collecting in
the duct, lint blowing back into the room,
and increased fire hazard.
W355
Exhaust Requirements
Layout
Whenever possible, install tumblers along an outside
wall where duct length can be kept to a minimum, and
make-up air can be easily accessed. Elbows and long
vents tend to increase drying time. Construction must
not block the airflow at the rear of the tumbler. Doing
so would prevent adequate air supply to the tumbler’s
combustion chamber.
Make-Up Air
A tumbler is forced air exhausted and requires provisions
for make-up air to replace air exhausted by the tumbler.
Venting
IMPORTANT: Installing in-line filters or lint
collectors will cause increased static pressure.
Failure to maintain the secondary lint system will
decrease tumbler efficiency and may void machine
warranty.
For maximum efficiency and minimum lint
accumulation, tumbler air must be exhausted to the
outdoors by the shortest possible route.
Proper sized exhaust ducts are essential for proper
operation. All elbows should be sweep type. Exhaust
ducts must be assembled so the interior surfaces are
smooth, so the joints do not permit the accumulation
of lint. DO NOT use plastic or thin foil ducts – rigid
metal ducts are recommended. Use exhaust ducts
made of sheet metal or other noncombustible material.
DO NOT use sheet metal screws or fasteners on
exhaust pipe joints which extend into the duct and
catch lint. Use of duct tape or pop-rivets on all seams
and joints is recommended, if allowed by local code.
IMPORTANT: Do not obstruct the flow of
combustion and ventilation air.
Make-up air openings should be as close to the
tumbler(s) as possible.
The required make-up air opening to the outside for
tumbler (includes both pockets) is:
each
220 square inches (1418 sq. cm) for T30 models
288 square inches (1856 sq. cm) for T45 models
Make-up air openings with louvers will restrict
airflow. The opening must be increased to compensate
for area taken up by louvers.
Make-up air openings for a room containing
tumbler(s) and/or gas fired hot water heater or other
gravity vented appliances must be increased
sufficiently to prevent downdrafts in any of the vents
when all tumblers are in operation. Do not locate
gravity vented appliances in the same room as
tumblers. If it is necessary to duct make-up air to the
tumbler(s), increase the area of the ductwork by 25%
to compensate for any restriction in air movement.
Verify that old ducts are thoroughly cleaned out before
installing new tumbler(s).
NOTE: Exhaust ducts must be constructed of sheet
metal or other noncombustible material. Such
ducts must be equivalent in strength and corrosion
resistance to ducts made of galvanized sheet steel
not less than 0.0195 inches (0.495 mm) thick. Local
codes may require additional thickness.
Where the exhaust duct pierces a combustible wall or
ceiling the opening must be sized per local codes. The
space around the duct may be sealed with
non-combustible material. Refer to Figure 2.

Tumblers – T30 and T45
IMPORTANT: For best performance provide an
individual exhaust duct for each tumbler. Do not
install a hot water heater in a room containing
tumblers. It is better to have the water heater in a
separate room with a separate air inlet.
Individual Venting
For maximum efficiency and performance, it is preferred
to exhaust tumbler(s) individually to the outdoors.
IMPORTANT: At no point may the cross sectional
area of installed venting be less than the cross
sectional area of the exhaust outlet of the tumbler.
The exhaust duct must be designed so the static back
pressure measured 12 inches (305 mm) from the
exhaust outlet does not exceed the maximum
allowable pressure specified on the installation sticker
on the rear of the tumbler.
NOTE: Static back pressure must be measured
with both pockets running.
The maximum allowable length venting of the same
diameter as the exhaust thimble is 14 feet (4.3 m) and
two 90° elbows or equivalent. If the equivalent length
of a duct required for an installation exceeds the maximum
allowable equivalent length, the diameter of a round duct
must be increased by 10% for each additional 20 feet
(6.1 m). Cross section area of a rectangular duct must
be increased by 20% for each additional 20 feet (6.1 m).
Refer to Table 1 to determine equivalent venting.

Table 1
Example: A 12 inch (305 mm) diameter duct’s
equivalent length of 14 feet (4.3 m) of duct and two
90° elbows is:
Equivalent Length = 14 feet + (2) 90° elbows
= 14 feet + 14 feet + 14 feet
= 42 feet (12.8 m)
With the tumbler in operation, and both pockets
running, airflow at any point in the duct should be at
least 1200 feet per minute (366 meters per meter) to
ensure that lint remains airborne. If 1200 feet per
minute cannot be maintained, schedule monthly
inspections and cleaning of the ductwork.
NOTE: The maximum length of a flexible metal
duct must not exceed 2.4 m (7.87 ft.) as required to

Figure 2
NOTE: Do not install wire mesh or screen in
exhaust duct opening to avoid lint build-up or
impacting proper discharge of air from tumblers.
NOTE: Where exhaust duct pierces a combustible
wall or ceiling, the opening must be sized per local
codes.
NOTE: Inside of duct must be smooth. Do not use
sheet metal screws to join sections.
Consult your local building code for regulations which
may also apply.
Manifold Venting
While it is preferable to exhaust tumblers individually
to the outdoors, a main collector duct may be used if it
is sized according to Figure 4 or Figure 5. This
illustration indicates minimum diameters, and should
be increased if the collector length exceeds 14 feet (4.3
m) and two 90° elbows. The diameter of a round duct
must be increased by 10% for each additional 20 feet
(6.1 m). Cross sectional area of a rectangular or square
duct must be increased 20% for each additional 20 feet
(6.1 m). Refer to Table 2 or Tabl e 3 to determine
equivalent ducting sizing. The collector duct may be
rectangular or square in cross section, as long as the
area is not reduced. Provisions MUST be made for lint
removal and cleaning of the collector duct.
from the exhaust outlet does not exceed the maximum
allowable pressure specified on the installation sticker
on the rear of tumbler. Static back pressure must be
measured with all tumblers vented into the collector
operating.
NOTE: Never connect a tumbler duct at a 90°
angle to the collector duct. Refer to Figure 3. Doing
so will cause excessive back pressure, resulting in
poor performance. Never connect two tumbler
exhaust ducts directly across from each other at the
point of entry to the collector duct.
With the tumbler in operation, and both pockets
running, airflow at any point in the duct should be at
least 1200 feet per minute (366 meters per meter) to
ensure that lint remains airborne. If 1200 feet per
minute cannot be maintained, schedule monthly
inspections and cleaning of the ductwork.
