Installation
Wall or Single Island Style Hoods
NOTE
If you have a back supply plenum (BSP), this must be
installed before the hood. Please see page 5.
The installation of the canopy hoods shall be in
accordance with NFPA 96 (latest edition) Standard for
Ventilation Control and Fire Protection of Commercial
Cooking Operations and ULC-S650 in Canada.
Greenheck does not recommend walking or standing
on the hood top as damage can result and may
void the warranty. If you must walk on the hood top,
protect the hood with additional support and planks
for flooring.
For wall/single island style hoods, prior to installation,
check with local authorities having jurisdiction on
clearances to combustible surfaces, etc.
With the hood still inside its packing crate, position the
unit beneath its installation location. Carefully remove
the packing crate. Place some protective material on
the floor next to the crate to avoid damaging the hood
as it is tipped on its side. Tip the hood carefully onto the
protective material. If you have filler panels, install them
now; refer to page 5, Filler Panel Installation. If you have
integral filler panels, no additional installation is needed.

Hood Installation Overview
If a back supply plenum is provided, install it first. Before
raising the hood, insert 1/2 in. (12.7 mm) diameter
threaded rod (by others) into hanger brackets on hood
top. Check the engineering drawings or UL label located
on the inside of the hood for proper hood height above
finished floor. Install filler panels if needed. Raise and
hang the hood from adequate roof or ceiling supports
All hanger brackets must be used and the hood must
be properly supported while lifting to prevent damage
or distortion to the hood. The hood must be hung level
to operate properly. After the hood is secured, make the
exhaust duct connections. The fire system distributor
must be contacted at this time. After the fire system has
been installed, mount the enclosures, then the supply
plenums. If a horizontal supply plenum is provided, it
should be installed before the enclosures. Finally, make
the electrical connections from the switches to the fans
and complete the fire system circuits as required by the
job specification.

Hanging the Hood
Before hanging the hood according to the hood
installation instructions, please check the following if
applicable:
1. Make sure the back supply plenum is properly
secured, as described on page 5.
2. If the ductwork for the back supply will not interfere
with the hood installation, it should be connected
now.
3. Any filler panels should be attached to the hood
before the hood installation. See page 5 for
instructions.
4. Lift the hood, and position it so the filler panels are
resting lightly on the top outside edges of the back
supply. The back supply is used to position the
hood only, it is not intended to hold any hood
weight.
5. Connect the remaining ductwork for the back supply
and the hood. It is recommended that caulk be
applied at the mating seams and surfaces of the
back supply, the hood, and the wall.
6. If the hood is equipped with clearance reduction
methods, refer to page 8 for special considerations
with hanging the hood.
