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.
