Planning the Installation
Choosing the right remote mount blower (see page 7)
Look on page 7 for a list of Fantech fans recommended for use with the HL Series Range Hood Liners. Some models remotely mount in the attic.
Other models are used when installation requires a roof mount or wall mount fan.
Electrical Connections
1. To reduce the risk of re and to properly exhaust air, the liner must
be exhausted to the outside. Never exhaust into a wall, an attic or a
concealed area in the building. This can create a potential hazard.
2. Consult a licensed ventilation contractor or qualied technician for
proper installation of exhaust ducting.
3. Locate the cooking area for minimum cross drafts – away from doors
and windows, when possible.
4. Ducts must be of adequate size and duct runs should be as short as
possible. Where turns are necessary, keep turning radius as large and
as smooth as possible.
5. The ducting must be air tight. Use a minimum of 2 sheet metal screws
at every duct joint. Then, seal the duct joints with high quality duct
tape.
6. Only use ductwork constructed of materials deemed acceptable by
state, municipal and local codes.
WARNINGS: Following Are Manufacturer’s Suggestions. Always Observe
Local Building Codes.
• Liners installed in custom canopies constructed of combustible
materials, should be installed with the combustible material structure
a minimum of 36” above the surface of the heating element.
• Liners installed in custom canopies constructed of non-combustible
materials, should be installed with the non-combustible material
structure a minimum of 30” above the surface of the heating element.
• Follow all instructions regarding minimum safe clearances and
installation location. Failure to do so may result in a safety hazard or
re.
• To reduce the risk of re use only metal ductwork.
• The hood liner is designed to install inside a custom hood enclosure
and operates with a remote mount blower (purchased separately). See
dimensional drawings (page 3) for hood dimensions. See chart (page 7)
for Fantech exhaust fans recommended for use with these units.
• A qualied person must complete the installation of this appliance.
• Plan the installation so that all minimum clearance are met or
exceeded.
• IMPORTANT: You must provide support framing and backing in the
areas in which you are securing the liner to in your custom canopy.
Failure to do so could damage the liner and void the warranty.
• The HL30 and HL36 is designed for use with a 8” diameter duct. The
HL 42 and HL 48 are designed for use with a 10” diameter duct. Use
only rigid metal duct.
• For a truly quiet kitchen ventilation system add a Fantech “duct
silencer” (LD Series) to the installation. The simple addition of an inline
duct silencer between the hood liner and the remote fan can typically
reduce the “perceived” sound level of the system by more than 50%.
For more information visit www.fantech.net.
• A quality cap with built in backdraft damper or an inline damper is
recommended to minimize cold air return through the duct when the
product is not in use.
• Always install ventilation products with an approved wall or roof cap.
• Duct performance is improved by using round, smooth metal duct work
instead of rectangular.
• If multiple elbows must be used, ensure that there is a minimum of 24”
of straight duct between any two elbows.
• Avoid ”S:” or back to back congurations caused by adjacent elbows.
• Route ducting to terminate at the hood liner.
1. Ensure that the power supply is disconnected before proceeding.
2. Verify that the power supply matches the ratings found on the
appliance data label before proceeding.
3. The complete appliance must be properly grounded at all times when
electrical power is applied.
4. Do not ground the appliance with the neutral (white) house supply wire.
A separate ground wire must be utilized.
5. Failure to complete electrical connections properly may result in
damaged or non-functional systems. Follow instructions carefully to
ensure proper installation.
• It is the owner’s responsibility to ensure that a qualied electrician
performs the electrical connection of this appliance. The electrical
installation, including minimum supply wire size, must comply with the
National Electric Code ANSI/NFPA 70-1990 (or latest revision) and
local codes and ordinances.

Instructions
1. A 15 to 20 amp electrical service is recommended for proper electri-
cal supply. Before determining, calculate amp ratings based on the
product label found on the liner and the ventilator. (Always observe
local building codes).
2. Always use a dedicated circuit.
3. Line load is calculated by adding the amperage of the halogen lights to
the rated amperage of the ventilator (either in-line or roof top). If the
ventilator is rated in watts rather than amps, divide the watts by 120
and this will give you the amperage rating.
4. The Fantech liner is supplied with a 5.0 amp variable speed fan con-
trol. Make sure the rated amperage on the ventilator does not exceed
5.0 amps. For larger ventilators rated above 5.0 amps, contact
Fantech Customer Service for recommendations.
5. The Fantech liner has been designed to accommodate several differ-
ent motor speed controls, (for example ThermadorTM model CTR3-Q)
Always consult the manufacturer’s installation instructions when sub-
stituting control switches.
6. Wire connections (see internal wiring schematic):
• Black –120 VAC from electrical panel (black)
• White- Neutral from electrical panel (white)
• Green – Ground from electrical panel (green)
• Red- 120 VAC variable control to 120 VAC of ventilator
The neutral wire (usually white) for the ventilator must connect to the
same neutral wire that comes from the electrical panel to the liner. It is
recommended to run a white neutral wire from the liner’s white neutral
wire along the same path as the red wire from the liner’s variable speed
control to the ventilator.

Securing the Liner
Securing instructions
1. Because the professional series liner was designed for custom appli-
cations, no mounting holes have been pre-drilled. This allows you to
attach the liner in the areas of the canopy which have ample support
and backing.
2. You must secure the liner through both right and left sides, through
the back and through the top.
3. Remove the filters. Mark and drill screw holes through the liner as
required for custom canopy. Secure the liner by driving screws (pro-
vided by others) through the liner into the framing and backing.
Connection to the vent pipe
1. The hood liner has an integral vent connection start collar that is
welded in place at the factory. Attach the vent pipe to the start collar
with a minimum of 3 equidistantly spaced screws.
2. Cover the screw heads and exposed seams with metal-backed tape.
3. Vent pipe should be supported in place separately from the hood liner.
Do not use the hood liner to support the vent pipe’s weight.
