WARNING
A drying tumbler produces combustible
lint. To reduce the risk of fire, the tumbler
must be exhausted to the outdoors.
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.
Layout
Wherever possible, install tumblers along an outside
wall, where duct length can be kept to a minimum and
makeup 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 combustion chamber.
Make-Up Air
A tumbler is forced air exhausted and requires
provisions for make-up air to replace air exhausted
by tumbler. Refer to Table 4.
IMPORTANT: Do not obstruct flow of combustion
and ventilation air.

Table 4
At a minimum, the National Fuel Gas Code
requires tumblers to have at least 1 square inch
(6.5 square cm) of opening for every 1000 Btu/hour
of input rating for proper combustion.

Example: A tumbler with a rated input of
120,000 Btu/hour requires 120 square inches of free
opening.
The additional opening recommended by the
manufacturer is required for optimum drying
and reliability.
Louvers in opening to outdoors will reduce airflow.
Opening must compensate for area taken up by
louvers.
Make-up air openings in rooms 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 between tumbler(s) and make-up air
openings. If it is necessary to duct make-up air to
tumbler(s), increase area of duct work by 25% to
compensate for any restriction in air movement.
Venting
For maximum efficiency and minimum lint
accumulation, tumbler 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 sheet metal screws to joint vent
sections.
