Fan Adapter
The Fan Adapter (
Figure 38
) is generally used
to connect an up-blast fan installed on a roof
curb or a site built support structure.
The size of the plate can be customized to fit
the fan and/or roof curb. When connected to
an up-blast fan (
Figure 39
), the plate mounts
on top of the roof curb which supports the fan
assembly.
The fan adapter can also be used to connect to
other types of device such as in-line fans, side
wall exhaust fans or utility fans which are also
used in commercial cooking applications.
The Fan Adapter is attached and sealed to
other pipe sections in the same manner as
described in
Chimney Joint Connection
Section.
Specify outside plate dimensions when
ordering the Fan Adapter.

Nozzle Length and Drains
The Nozzle length (
Figure 40
) can be used as a port section in boiler applications
for taking draft and temperature measurements while setting up the boilers. It may
also be used to integrate automatic cleaning or fire suppression devices (by others)
to a Grease Duct installation.
The Nozzle Length comes with a 3/4" NPT nipple (both ends) that can be connected
to an automatic water/detergent injection cleaning system which may be required for
some projects.
It's is also intended for connecting devices such as CO2 extinguishing systems
(NFPA 12), sprinkler systems (NFPA 13), foam-water sprinkler systems (NFPA 16),
or dry chemical extinguishing systems (NFPA 17) where jurisdictions require
additional fire suppression.
Drain Sections (horizontal and vertical) and Drain Tee Caps (
Figure 41
) are also
available to collect rainwater and condensation, or to collect water from the cleaning
process. Drain Tee Caps may also be used to drain grease when attached to a Tee
installed at the base of a rise. All drains are equipped with a 1" NPT male nipple to
be connected to a suitable disposal system.
Nozzle Lengths and Drains are attached and sealed to other pipe sections in the
same manner as described in
Chimney Joint Connection
Section.
