DO NOT THROW AWAY,

PROPERTY OF THE HOME OWNER!

Imperial Cal Products, Inc.

Any cosmetic defects must be reported to us prior to installation.
Once this hood is installed, ICP will NOT accept any responsibility

for any cosmetic blemishes, scratches or dents in the Canopy.
Save all original packaging if you wish to return for any reason!

FIRST:

Check your local building and electrical codes.

WARNING:

To reduce the risk of fire or electrical shock, Do Not use any two speed motor units with a Solid
State control devise.

CAUTION:

To reduce the risk of fire or personal injury and to properly exhaust air, be sure to duct air to the
outside. DO NOT vent exhaust air into spaces within wall, attics, ceilings, crawl spaces or
garages. When venting to the outside make duct run as short and straight as possible.
Avoid using elbows if at all possible as this will reduce your performance. Every elbow will
decrease the performance and we will not guarantee the effectiveness of the range hood.

No Performance Warranty when used above BBQ Style Grills.

DO NOT use duct pipe smaller than the outlet duct opening on the hood, this will reduce
performance and void the warranty. DO NOT use flex ducting. Also, use either a Roof Cap or
Wall Cap to end run. Be sure that all joints are taped securely in place. It is essential to have the
proper distance between the bottom of the range hood and the cooking surface below. In most
cases the cooking appliance manufacturers specifications will establish the fire safe minimum
distance required, although there are other factors to consider:

 Local Building Codes
 Cross directional air movements ie: open windows, air conditioning/heating outlets, cooling

fans, etc.

 Overall size of the cooking appliance and surrounding countertop surfaces.
 Range hood model selected.

For best performance distance between cooking surface and the bottom of the hood is 30” and
36”. Check local codes and appliance specifications. Keep in mind, increasing the distance will
decrease the performance.

THERMOSTAT: PS or BP Units ONLY. When cooking surface reaches 130 degrees, the unit will
automatically turn ON to the highest setting and won’t be able to be turned off until the area has
cooled down. For safety, it’s best to have unit on while cooking. (This thermostat will NOT prevent
fires. Fires are most often cause by excessive grease build up.)

TWIN UNITS ONLY - Transitioning two pipes into one is NOT recommended. CFMs are reduced
by 25% and the Performance Warranty will be void.

Read Before Starting Installation!

Inspect your range hood prior to installing!

wiring must be done by a Qualified person or persons in accordance with all applicable
Codes and Standards, including Fire-Rated Construction.

CAUTION: Be sure that incoming power is turned off!

1. Electrical Supply Required: 120 Volt, 60 Hz, 15 or 20 Amp, 2 wires with ground.

Properly grounded branch circuit.

2. Planning the Location: You must first determine the exact

will attach to the ceiling.

A. Use a plumb line to transfer an outline of the cooking surface perimeter to the same
location above on the ceiling.

B. The typical depth of a cook top surface is 25”, which is smaller than the hood canopy
depth: Pyramid at 32”, Slim Line Island at 28” & 24”, and Contemporary at 28”.
In any case hood should project 1-1/2” beyond the front edge of the cooking surface.
*(Models with an 8” transition will project approx. 2-3/4” beyond cooking

Surface.)
Note:

The rear projection of the 32” depth unit will overhang 10”, so plan your counter top
surface accordingly. Also, the hood should be centered right to left space permitting,
overhang 3” on each side.

TWIN UNITS ONLY

3. Stack Support Frame Preparation:

 The Model Hood being installed

will always determine the
support frame size required;
10-3/4”, 15-3/4” or 22-3/4” Wide
and 11-1/2” Deep.

 At the proper ceiling location

install upright 2 x 4 cross framing
between ceiling joists. The
location to be on center, side to
side the overall width of the
support structure selected:
10-3/4”, 15-3/4”, 22-3/4”.

 Allow electrical wiring and vent

pipe to go 6” past bottom of wood
frame. Finish the ceiling surface
as required marking the location
of the cross framing (or backing)

beneath.

4. Installing the Support Frame:

 Secure the support frame to the ceiling with

six #8 wood screws, 2 1/2” long, using the pre
drilled holes located in the two support
brackets.

 Check the frame to sure it is vertically plumb,

in both directions, and correctly positioned
above the cooking surface. The frame may be
adjusted to allow for some ceiling
imperfections by using the four adjusting
screws in the elongated holes located on the
two mounting brackets.

 Now install four #10 x 5/8”

screws in the pre drilled fixed
bracket holes “Locking” the
support structure in position.

*It is NOT recommended to use 2
dampers during installation. You
have the option to put a external
damper or use the existing damper
already on the unit.

5. Installing the Hood: Caution - DO NOT handle hood using Motor Mounts as
Gripping Points!

 Remove all the mesh filters located at the bottom of

your hood.

 Remove the BLACK tape that holds the damper blades

closed. (It is NOT recommended to use two (2) dampers
during installation. You have the option to use an
external damper or use the existing damper already on
our unit.) Make sure not to obstruct damper operation
and properly seal all duct connections with duct tape.

 Slim Line & Contemporary: Lift hood and position the

support frame between the two mounting brackets that
have been factory installed on the hood top. Secure
with four #8 1” screws by installing them through the
pre-drilled holes in the brackets, into the frame.

 Pyramid: Remove the Power Liner assembly (C2000)

by unscrewing the four mounting nuts and washers
located at each corner of the hood. Install the canopy
(shell) in the same manner as the Slim Line canopy.
Re-install the C2000 back into the

canopy.

 Connect duct work to the vent opening located at the

top of the hood.

6. Electrical Connections:

 Verify that power is turned off at source. Remove

junction box cover from the underside of the hood at the
power supply location. Feed house electrical lead
through the pre-punched hole located in the hood top,
then into the hood junction box. Connect appropriate
wire leads, secure with wire nuts and re-install junction
box cover.

7. Decorative Stack Cover:

 Verify the actual dimensions between hood top and

ceiling. Test fit the stack by positioning the front por­tion of the stack cover in place at all four sides of the
support frame. Adjust height if required. Now remove
the double face tape covering from the stack support
tabs located next to the canopy mounting brackets
and also from the two front vertical edges on the three
sided portion of the stack cover.

 Set the stack cover in place around the support frame,

making sure of a tight joint at the top of the canopy.
Now secure the cover piece using the four screws pro­vided. The cover is designed to “Float” where it meets
the ceiling. Should a small gap exist, it may be
caulked or hidden with a trim molding of your choice.

8. Finalized Installation:

 You may now remove the protective clear covering,

and re-install the aluminum mesh bottom filters. Reconnect your electrical supply
and test the operation of your motors and lights.
