Installation Preparation
Installation Considerations
The chimney hood requires the ducting to be vented to the
outside. It cannot be used in conjunction with a
recirculation unit.
Hood installation height above a cooktop, rangetop or
range can vary. To obtain the necessary installation height
above a cooktop, rangetop or range, consult the
appliance's installation manual.
NOTICE:
The hood could incur some damage from heat if a
THERMADOR PROFESSIONAL series range or rangetop
is operated with multiple burners at high settings under a
hood that is installed at minimum clearances while the
hood is turned off.
Hood Width
The hood width should be no less than the width of the
cooking surface. For proper performance, the housing must
cover the entire cooking surface.
Where space is not restricted, a wider hood can be used to
increase coverage.
The hood needs to be centered over the cooking surface
for best performance.
Distance From Cooking Surface
The installation height has a minimum height of 30”
(762 mm) from the cooking surface; however, it is
necessary to follow the cooking appliance manufacturer’s
installation instructions for proper hood height.
Unit Weight
When calculating the load for the housing support system,
be sure to consider the weight of the ventilation unit.

HPCB48NS 63 lbs. (29 kg)
NOTE: “HPCN” models do not include the weight of an
integral blower. The integral blower weight is an
additional 16 lbs. (7 kg). “HPCB” models do include the
weight of an integral blower.
IMPORTANT:
The supplied weights address only the ventilation unit
and blower. Installer must account for weight of any
materials of construction when calculating the total dead
weight load of installation, including but not limited to:
wall, tile, mortar, plaster, brick, finishes, partitions, and
other similarly incorporated architectural and structural
items. It is the responsibility of the owner and the
installer to determine if additional requirements and/or
standards apply to specific installations.

English 6
Wall Framing
Due to the weight of the hood, make sure the wood
mounting bracket is attached to all available wall studs.
Framing must be fastened together and to ceiling joists to
provide enough structural strength to support the weight of
the hood and internal blower, if applicable.
Wall framing should be, at minimum, made of 2" x 4"
lumber. Proper structural support is required to
accommodate the weight of the hood.
Ductwork Preparation
Discharge Direction
The exhaust air is discharged upwards through a duct or
directly through the outside wall into the open.
The hood can be mounted on the wall only with a vertical
discharge.
Ducting Recommendations
Proper performance is dependent upon proper ducting.
Local building codes may require the use of make-up air
systems when using ducted ventilation systems greater
than speci¿ed cubic feet per minute (CFM) of air
movement.
The speci¿ed CFM varies from locale to locale. It is the
responsibility of the owner and the installer to determine if
additional requirements and/or standards apply to specific
installations.
DO NOT USE FLEXIBLE DUCT; it creates back pressure/
air turbulence and reduces performance.
Always install a metal vent cover where the ductwork exits
the house.
COLD WEATHER installations should have an additional
backdraft damper installed to minimize reverse cold air flow
and a nonmetallic thermal break to minimize conduction of
outside temperatures as part of the ductwork. The damper
should be on the cold air side of the thermal break. The
break should be as close as possible to where the ducting
enters the heated portion of the house.
MAKE-UP AIR: Local building codes may require the use
of make-up air systems when using ducted ventilation
systems greater than specified CFM of air movement. The
specified CFM varies based on locale. It is the
responsibility of the owner and the installer to determine if
additional requirements and/or standards apply to specific
installations.
The unit cannot be used in conjunction with a recirculation
unit.
THERMADOR recommends not exceeding 50 ft (15.24 m)
of duct.
Keep duct runs as short and straight as possible. Elbows
and transitions fittings reduce air flow efficiency. Back to
back elbows and “S” turns give very poor delivery and are
not recommended. A short straight length of duct at the
inlet of a remote blower gives the best delivery.
Hoods are supplied with a 10" (254 mm) round transition. A
locally supplied transition is required for other sizes.
Use “Equivalent Duct Lengths for Commonly Used
Transitions” on page 7 to compute permissible lengths for
duct runs to outdoors.
WARNING!
Vent ducting directly outdoors (not into an attic,
underneath the house, into the garage or into any
enclosed space).

Electrical Requirements
The unit requires a 120V AC, 60Hz. 15A branch circuit.
The hood should only be connected to a dedicated circuit
(with ground) that has been installed according to relevant
regulations.
When connected to a GFCI-protected supply,
THERMADOR PROFESSIONAL hoods are suitable for
use in damp locations that are protected from outside
weather conditions and not subject to saturation with water
and other liquids, but can be subject to moderate degrees
of moisture (such as an outdoor covered patio or lanai
area). Refer to local codes, NEC/CEC, and or the Authority
Having Jurisdiction (AHJ) for additional information.
Check your local building codes for proper method of
installation. In the U.S., if there are no applicable local
codes, this unit should be installed in accordance with the
National Electric Code ANSI/NFPA No. 70, Current Issue.
In Canada, installation must be in accordance with the CAN
1- B149.1 and .2 - Installation Codes for Gas Burning
Appliances and/or local codes.
The appliance must be grounded. In the event of an
electrical short circuit, grounding reduces the risk of electric
shock by providing a wire that allows the electric current to
escape.

IMPORTANT:
The hood needs to be centered over the cooking surface
for best performance.
Wood Hanging Bracket
1. Calculate the hood installation height as described on
page 9.
2. Draw a horizontal line at a distance above the cooking
surface equal to the hood installation height plus 16”
(406 mm). This line is the mounting location of the
wood bracket shipped with the hood.
3. Find the centerline of the hood. Draw a vertical line
along this centerline up to the horizontal line drawn in
Step 2.
4. The hood is mounted to the wall using the wood
bracket shipped with the hood. Remove the wood
bracket located at the back side of the hood by
removing the two shipping screws (discard screws).
Mark the centerline of the wood bracket.
5. Locate a stud on both sides of the hood centerline to
use for mounting the wood bracket as shown in

Hanging the Chimney Hood
The transition supplied with the hood connects to standard
10-inch round duct. Installations require a cutout in the
ceiling to accommodate 10" (254 mm) duct and the ½”
(13 mm) conduit carrying power to the unit.
Chimney extensions, sold separately, are available to cover
the space between the top of the hood and ceiling (see
“Chimney Extension Installation (optional)” on page 16).
1. Use a T-10 Torx head screwdriver to remove the screw
securing the junction box channel covering the wires.
2. Remove one circular knockout behind junction box
channel.
3. Using two people to lift, rest the hood on the wood
bracket. Make sure the wood bracket fits into the
recess on the back of the hood.
4. From inside the hood, predrill the holes labeled “J” in
Figure 10 in hood into the wood bracket with a 5/8”
(16 mm) drill bit. Secure the hood to the wood bracket
with five (5) 1½” (38 mm) screws.
5. Connect additional ducting.

Blower Motor Installation
HPCB36NS and HPCB48NS models have a VTN1080
integral blower included. All other blower models are sold
separately. Use only THERMADOR blowers with these
ventilation hoods. See Table 1 Blower & Circuit Breaker
Ratings for recommended blowers. Contact Customer
Service for additional options.
All hood models are rated for 120V AC installed with a
blower listed in Table 1, using a 15 amp dedicated circuit
breaker.
Blower selection will vary based on the volume of air that
needs moved and the length and location of the duct run.
For long duct runs with multiple turns and bends, consider
using a more powerful blower. For the most efficient air-
Àow exhaust, use a straight run or as few elbows as
possible (refer to “Ductwork Preparation” on page 6).
Integral Blower Installation Only
1. The blower is attached to the hood using weld studs
provided on the mounting plate (see Figure 14).
2. Guide the motor mounting plate over the studs.
3. Attach (4) nuts (included with hood) to the weld studs.
Tighten nuts with a 3/8” (9 mm) nut driver to secure the
blower to the hood.
Wiring the Hood with an Integral Blower
Integral Blower model VTN1080 should be installed after
hood is mounted to the wall.
