Installation GL16
2-6
NOTE: Exceeding a 45° elbow
angle rotation from vertical for the
blower may not maintain proper air
movement and may cause the
sail switch to operate incorrectly.
Installing the Exhaust Blower
1. Position the 10" (254 mm) exhaust blower
in the opening in the center of the canopy.
Secure the blower in place with the four
machine screws provided.
2. Extend the 10" (254 mm) round exhaust
ducting from the exhaust blower output
to the outside discharge point.
The discharge must be properly designed to
maintain the required air flow:
• To ensure proper operation of the exhaust
canopy sail switch and the correct removal
of by-products, it is recommended that the
unit be connected to a separate exhaust
system.
• The discharge must be protected from
backdrafts and precipitation.
• No screen or filter should be connected
at the discharge unless it is connected to
a commercial lint collector.
Exhaust Blower Installation
The exhaust canopy includes a blower to expel
excess heated air and moisture. This system
contributes to the comfort of operating personnel,
proper operation of the unit, and reduction of
maintenance time. All labor and materials
required for venting the unit are a local
responsibility. Comply with local codes and
regulations for proper installation.
Ductwork
The 10" (254 mm) diameter ductwork and all
associated hardware for the exhaust system must
be locally supplied. Follow local codes and good
engineering practice to design the exhaust system.
Every effort should be made to keep the ductwork
as short and straight as possible. Check the
canopy nameplate for the maximum length of
ductwork. Do not use elbows greater than a 45°
angle in the exhaust ducting.
Locating the Exhaust Blower
NOTE: Proper installation is
required for all warranties and
applicable certification labels to be
valid. Call the factory if you have
any questions.
The exhaust blower is designed for vertical
installation directly on top of the exhaust canopy
(Figure 2-10). It is particularly important that a
straight section of ductwork be attached directly
to the blower discharge. When it is installed, the
blower can be rotated up to a 45° angle to the left
or right of vertical to help make this configuration.
CAUTION
Do not change the mounting
position of the sail switch
and do not reverse the
blower housing.
