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.
