Installation Operation and Maintenance Manual
Supplement for UL-762 Listed (Restaurant Exhaust) Fans
This supplement to the TCB Installation Operation and Maintenance Manual is intended to provide additional
information when dealing with fans used in applications involving grease laden air. Refer to the TCB Installation,
Operation and Maintenance Manual (PN 456557) for items that are not specifically addressed (handling, storage,
start-up, troubleshooting and maintenance) in this supplement.
Installation Practices
• All units used in applications with grease laden air are to be installed in
accordance to NFPA 96, IMC 2203 and local codes. Consult local code
authorities for your specific requirements.
• Fans shall be located in an easily accessible area of adequate size to allow
for service or removal. Exhaust fans with ductwork connected to both ends
shall have access for cleaning and inspection within 3 ft (0.92 m) of each end
of the fan (NFPA 96).
• Maintain a minimum clearance of at least 18 inches (457 mm) to combustible
material and 6 inches (125.4 mm) to either limited-combustible or
noncombustible material (NFPA 96).
• Fans are to be installed with the motors in the 3 or 9 o'clock (C or G) positions. Motors located in this
configuration may cause an unbalanced load that should be considered if isolators are to be used. Equalized
loading between isolators can be achieved through the use of mounting rails. Refer to the TCB IOM for details
and installation instructions involving mounting rails.
• It is recommended to install the fan near the end of the duct run. This limits the amount of positive pressure in
the system. The diagram below illustrates an inline fan exhausting air near the final termination point. See local
codes and NFPA 96 for any restrictions and requirements for wall terminations.
• A drain is provided for single-point drainage of water and residue. When installed correctly, one of the two
housing drains will be located on the bottom. This drain is used to remove any accumulated grease and / or
cleaning solutions. Some means for collection of this residue must be provided, either a container directly under
the drain or use an adapter and pipe to carry the residue to a remote collection point. Remove drain plug prior
to connection to grease collection device.
• Provision to open and remove the access door is required for periodic cleaning and maintenance. The access
door is clearly labeled and indicates that access to this location must be maintained. Any enclosure openings
required to reach the access panel shall be large enough to allow for the removal of the panel.
