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.
A drying tumbler produces combustible
lint. To reduce the risk of fire, the tumbler
must be exhausted to the outdoors.
W057
To reduce the risk of fire and accumulation
of combustible gases, DO NOT exhaust
tumbler 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.
W059
WARNING
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
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
WARNING
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 the air exhausted
by the tumbler.
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 is:

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 between tumbler(s) and
make-up air openings. If it is necessary to duct makeup air to the tumbler(s), increase the area of the
ductwork by 25% to compensate for any restriction in
air movement.
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 flexible 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.
Verify that old ducts are thoroughly cleaned out before
installing new tumbler(s).
Make-up air openings with louvers will restrict
airflow. The opening must be increased to compensate
for area taken up by louvers.
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
noncombustible material. Refer to Figure 2.
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.

Example: A 12 inch (305 mm) diameter duct’s
equivalent length of 14 feet (4.3 m) of duct and two
90° elbows is:
With the tumbler in operation, airflow at any point
in the duct should be at least 1200 feet per minute
(366 meters per minute) to ensure that lint remains
airborne. If 1200 feet per minute cannot be
maintained, schedule monthly inspections and
cleaning of the ductwork.
NOTE: Static back pressure must be measured
with the tumbler 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.
NOTE: The maximum length of a flexible metal
duct must not exceed 7.87 ft. (2.4 m) as required to
meet UL2158, claus 7.3.2A.

NOTE: Do not install wire mesh or screen in

NOTE: Where exhaust duct pierces a combustible
wall or ceiling, the opening must be sized per local
Figure 2
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.
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 and Figure 5. This
illustration indicates minimum diameters, which
should be increased if the collector length exceeds 14
feet (4.3 meters) and two 90° elbows. The diameter of
a round duct must be increased by 10% for each
additional 20 feet (6.1 meters). Cross sectional area of
a rectangular or square duct must be increased 20% for
each additional 20 feet (6.1 meters). Refer to Table 2
and Table 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.
The vent collector system 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 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, airflow at any point in
the duct should be at least 1200 feet per minute (366
meters per minute) to ensure that lint remains airborne.
If 1200 feet per minute cannot be maintained, schedule
monthly inspections and cleaning of the ductwork.

connections should be made by a qualified
