Installation Instructions
Receiving Inspection
Upon delivery, visually inspect crate, carton and parts
for any visible shipping damage. If the crate, carton or
cover are damaged, or signs of possible damage are
evidence, 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.
A written claim should be filed as soon as possible
with the carrier if items are damaged or missing.
IMPORTANT: Remove the shipping tape from the
two back draft dampers located in the exhaust
thimble.
Materials Required
•One disconnect switch with fuses or Fusetron(s)
(acceptable for 120 Volt installations).
NOTE: For voltages higher than 120 Volts, a circuit
breaker must be used.
•Two gas shut-off valves for stacked tumblers.
Facilities Required
Layout
Whenever possible, tumblers should be installed along
an outside wall where duct length can be kept to a
minimum, and make-up air can be easily accessed.
Construction must not block the airflow at the top rear
of the tumbler. Doing so would prevent adequate air
supply to the tumbler’s combustion chamber.
The stacked drying tumbler has been specifically
designed to provide twice the drying capacity utilizing
the same floor space as the standard 30 lb. (31-5/8
inches wide) drying tumbler.
The only thing common between the stacked drying
tumbler and the standard drying tumbler is the floor
space requirements. Twice the drying capacity means
two separate heat sources, two separate cylinders/
drives, and two separate controls.
Floor
The drying tumbler may be installed on any level floor
capable of supporting 100 pounds per square foot (488
kg/square meter). Floor covering materials such as
carpeting or tile should be removed.
Shipping Braces
To facilitate installation, the shipping braces located
on the lower left and right rear corners may be
removed. To remove, simply remove the four round
head screws from each brace, remove and discard
brace, and replace the screws in the same holes they
were removed from.
NOTE: The shipping brace need not be removed if
it does not interfere with installation. If you do not
remove the shipping brace, you will need to add an
additional 5/32 inch (4 mm) to your installation
space.
Venting
For maximum efficiency and minimum lint
accumulation, tumbler air must be exhausted to the
outdoors by the shortest possible route.
Proper sized ducts are essential for proper installation.
All elbows should be sweep type. Do not install
elbows with a radius less than shown in the table
below. Exhaust ducts must be assembled so the interior
surfaces are smooth, and so the joints do not permit the
accumulation of lint. Do not use sheet metal screws to
join vent sections. 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.
NOTE: Exhaust ducts must be constructed of sheet
metal or other non-combustible material. Such
ducts must be equivalent in strength and corrosion
resistance to ducts made of galvanized sheet steel
not less than 0.0195 inch (0.495 mm) thick.
Where the exhaust duct pierces a combustible wall or
ceiling, an opening having a diameter of four inches
(10.2 cm) larger than the diameter of the exhaust duct
shall be provided, with the duct centered in the
opening. When ducts pass through walls, ceilings,
floors or partitions, the space around the duct shall be
sealed with non-combustible material. Refer to
Figures 1 and 2.
A tumbler produces combustible lint. To
reduce the risk of fire, and the
accumulation of combustion gases, the
tumbler must be exhausted to the
outdoors.

Individual Venting
For maximum efficiency and performance, it is
preferred to exhaust tumbler(s) individually to the
outdoors. Refer to Figure 1 and 2. AT NO POINT
MAY THE CROSS AREA OF INSTALLED
VENTING BE LESS THAN THE CROSS AREA
OF THE EXHAUST THIMBLE OF THE
TUMBLER.
THE MAXIMUM ALLOWABLE LENGTH OF
VENTING IS 14 FEET (4.3 M) AND TWO 90°
ELBOWS, OR EQUIVALENT. The table below
shows how to determine equivalent length of venting
for 90° elbows:
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 percent for each additional 20 feet.
The cross area of a rectangular duct must be increased
20% for each additional 20 feet (6.1 m).
With the tumbler in operation, airflow at any point in
the duct must be at least 1200 feet (366 m) per minute
to ensure that the lint remains airborne.
Combined Exhaust Manifold Venting
The upper and lower units may be exhausted into a
combined exhaust manifold, refer to Figure 2. Refer to
Figure 3 for proper manifold duct construction. THE
MAXIMUM LENGTH OF 10 INCHES (25.4 cm)
DIAMETER EXHAUST DUCT BEYOND THE
MANIFOLD DUCT IS 14 FEET (4.3 m) AND
TWO 90° ELBOWS, OR EQUIVALENT.
Collector 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. These illustrations
indicate minimum diameters, and should be increased
if the collector length exceeds 20 feet (6.1 m). The
collector duct may be rectangular in cross section, as
long as the area is not reduced. Provisions should be
made for lint removal and cleaning of the collector
duct.
The collector duct must be tapered, as shown in
Figures 4 and 5. The individual tumbler ducts must
enter the collector duct at a 45° angle in the direction
of airflow. Never connect a tumbler duct at a 90° angle
to the collector duct. 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.
The collector system must be designed so the static
back pressure measured 12 inches (30.48 cm) from the
exhaust thimble does not exceed the maximum
allowable pressure specified on the installation sticker
on the rear of the tumbler. This must be measured with
all tumblers running that are vented into the collector.
DUCT DIAMETER EQUIVALENT LENGTH OF
STRAIGHT DUCT
6 in (15.3 cm) One 90° elbow = 7 ft (2.1 m)
8 in (20.3 cm) One 90° elbow = 9.3 ft (2.8 m)
10 in (25.4 cm) One 90° elbow = 11.6 ft (3.5 m)
12 in (30.5 cm) One 90° elbow = 14 ft (4.3 m)
FORMULA: Equivalent Length (feet or meters) =
1.17 x Duct Diameter (inches or centimeters)
EXAMPLE: A 6 inch diameter duct’s equivalent
length of 14 feet of vent and two 90° elbows is:
Equivalent
Length: =14
ft (4.3 m) + (2) 90° elbows
=14
ft + 7 ft + 7 ft (4.3 m + 2.1 m + 2.1 m)

Make-Up Air
A tumbler is forced-air exhausted and requires
provisions for make-up air to replace the air exhausted
by the tumbler.
The manufacturer’s recommended make up air
opening for each tumbler is 144 square inches (929 sq.
cm) of free area. At a minimum, the National Fuel
Gas Code requires tumblers to have at least one
square inch (6.5 sq. cm) of opening for every 1000
BTU/hr. of input rating for proper combustion.
EXAMPLE: A tumbler with a rated input of 120,000
BTU/hr. (30,240 Kcal) requires 120 square inches
(774.2 sq. cm) of free opening.
Protective louvers in the opening to the outdoors can
reduce air movement by approximately 40 percent.
The opening must compensate for the area taken up by
the louvers.
NOTE: The make-up air openings into a room
containing tumblers, and a 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 install gravity vented appliances between
tumblers and air inlet openings.
Positioning the Drying Tumbler
The tumbler may be removed from the skid before
moving it to the installation location, or it may be
moved while still attached to the skid. To remove
tumbler from the skid, unscrew the four shipping
capscrews (one at each corner) and lift the tumbler
from the skid.
The leveling legs will be in a bag inside the cylinder.
Screw the four leveling legs into the level adjusting
fittings from the bottom.
IMPORTANT: The tumbler should be slid in place
using the wooden crate pad supplied on the
shipping crate to prevent damage to the flooring.
Slide the tumbler to its permanent location and level.
Keep the tumbler as close to the floor as possible. The
tumbler must rest firmly on the floor so weight of
tumbler is evenly distributed. Tumbler must not rock.
Shim under the corners to level and stabilize the unit.
Drying Tumbler Enclosure
Construction
IMPORTANT: DO NOT block the airflow at the
top rear of the tumbler with laundry, etc. Doing so
would prevent adequate air supply to the tumbler’s
heat chamber.
A typical enclosure is shown in Figure 5. Note that the
enclosure does touch the tumbler top and side panels.
Note, too, the minimum and maximum dimensions. Be
aware that there may be local codes and ordinances
which must be complied with.
IMPORTANT: Install tumblers with sufficient
clearance for servicing and operation. Refer to
Figure 5.
TO FACILITATE INSTALLATION: To ensure room
for leveling, adjusting and lining up the tumblers, size
the enclosure opening three inches (7.6 cm) larger than
the tumbler dimensions. After the tumblers are lined
up and level, close the gap with a trim board.
To reduce the risk of serious injury, install
lockable door(s) to prevent public access
to rear of tumblers.

IMPORTANT: Do not lift under the belt guard or
tip the unit. Serious drive train damage will occur.
Leveling the Drying Tumbler
Each tumbler should be leveled within 1/8 inch (3
mm) from front to rear and 1/8 inch (3 mm) from side
to side. Check front to rear level by rotating the clothes
cylinder until one rib is at the bottom, then place a
level on the rib. Check side to side level by placing a
level across the center of the top panel.
IMPORTANT: An unleveled tumbler can cause
rapid bearing wear, internal misalignment,
scraping, noise, and possible clothes damage.

Tumbler exhaust duct must be smooth inside and be sized based on the following air flow data:
450 CFM maximum and 350 CFM minimum at .3 W.C. (See information on VENTING in this
manual for duct dimensions).
For proper combustion, supply a two square foot (.19 sq. meter) opening for outside makeup air.

Gas Requirements (Gas Drying Tumblers)
Before connecting the gas piping to the tumbler, make
certain that gas service is the same as that specified on
the serial plate.
IMPORTANT: Any product revisions or
conversions must be made by the Manufacturer’s
Authorized Dealers, Distributors or local service
personnel.
IMPORTANT: The installation must comply with
local codes or, in the absence of local codes:
- with the latest edition of the “National Fuel Gas
Code”, ANSI Z223.1 in the U.S.A.
- with CAN1-B149.1 or CAN1-B149.2 in Canada
- and Australian Gas Association/Australian L.P.
Gas Association requirements in Australia
The size of gas service pipe is dependent upon many
variables (lengths, tees, etc.). Specific pipe size
information should be obtained from the gas supplier.
Refer to table in Figure 7 for general pipe size.
A dirt and water vapor pipe trap must be furnished and
installed by customer. Refer to Figure 6.
It is important that equal pressure be maintained at all
tumbler gas connections. This can best be done by
installing a one inch (2.54 cm) pipe gas loop as shown
in Figures 8 and 9.
Before connecting the gas piping to the tumbler, make
certain gas service is the same as that specified on the
serial plate.
NATURAL GAS service must be supplied at 6-1/2 ±
1-1/2 inch water column pressure (1.62 ± .37 kPa).
L.P. GAS service must be supplied at 11 ±.3 inch
water column pressure (2.74 ±.07 kPa).
Pressure checks can be made at the shut-off valve.
Refer to Figure 6.
To reduce the risk of fire or explosion, DO
NOT CONNECT THE GAS LINE TO THE
TUMBLER IF THE GAS SERVICE IS NOT
THE SAME AS THAT SPECIFIED ON THE
TUMBLER SERIAL PLATE! It will first be
necessary to convert the gas burner orifice
and gas valve. Appropriate conversion kits
are available.
W060
WARNING
To reduce the risk of fire or explosion, if the
tumbler is to be connected to Liquefied
Petroleum (L.P.) gas, a floor level vent to
the outdoors must be provided in the room
where the tumbler is installed.
