Installation Preparation

Installation Considerations

Clearances and requirements
Hood installation height above a cooktop, range top or range can vary. To obtain the necessary installation height above a cooktop, range top or range, consult the appliance’s installation manual.

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 capture area.
For proper performance, the hood must be centered horizontally above the cooking surface.

Distance From Cooking Surface
For gas cooktop & range installations: Mount the hood so the bottom is at least 30” (76.2 cm) above the cooking surface.
For electric/induction cooktop & range installations: Mount the hood so the bottom is at least 30” (76.2 cm) above the cooking surface.

NOTICE: The hood could incur some damage from heat if a THERMADOR MASTERPIECE® series cooktop is operated with multiple burners at high settings under a hood that is installed at minimum clearances.
Unit Weight
This vent hood is heavy. Adequate structure and support must be provided in all types of installations. When calculating the load for the housing support system, be sure to consider the weight of the ventilation unit.

Unit	Weight
30 ’ (76 cm)	40.3 lb (18.3 kg)
36 ’ (91 cm) Single blower	42.5 lb (19.3 kg)
36 ’ (91 cm) Dual blower	54.6 lb (24.8 kg)
48 ’ (122 cm)	65.9 lb (29.9 kg)

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.

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.

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.
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.

WARNING
The appliance must be grounded.

Electrical Data on the Data Rating Label
Data, including the model and serial number, is located on the product data rating label inside the appliance, visible after removal of the filter frame.

Ductwork Preparation

Discharge Direction
The exhaust air is discharged upwards through a duct. The hood can be mounted 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 specified cubic feet per minute (CFM) of air movement. The specified 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 use metal ductwork.
Always install a metal vent cover where the ductwork exits the house. Hood must be vented to the outside of building only.

COLD WEATHER installations should have an additional backdraft damper installed to minimize backward cold air low 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 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.
For safety reasons, ducting should vent directly outdoors (not into an attic, underneath the house, into the garage or into any enclosed space).
THERMADOR® recommends not exceeding 50 equivalent length (ft) (15.24 m) of duct.
Keep duct runs as short and straight as possible.
Elbows and transitions fittings reduce air low 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 11 to compute permissible lengths for duct runs to outdoors.

Venting Methods
This hood is factory set for venting through the roof (vertical discharge) or wall (horizontal discharge). A 10” (254 mm) round duct system is needed for installation (not included).
NOTE: Flexible duct is not recommended. Flexible ductwork creates back pressure and air turbulence that greatly reduce performance.
Vent system can terminate either through the roof or wall.
Always install a metal vent cover where the ductwork exits the house.

For Non-Vented (recirculating) Installations
If it is not possible to vent cooking fumes and vapors to the outside, models HMWB30WS and HMWB36WS can be used in the non-vented (recirculating) version, using the recirculating kit (sold separately). Fumes and vapors are recycled through the grid.
See optional accessories section.

Hood Transition

Vertical Discharge Transition
The hood is shipped ready for vertical discharge.
The transition supplied with the hood connects to standard 10” round duct. The figure shows the transition connected for vertical discharge.

Assembly of the Transition

A minimum height clearance of 4 5 ⁄16’’ (110 mm) is needed above the hood for transition mounting. See “General Information” on page 6 for overall hood dimensions.

Depending on direction of discharge, align mounting holes at base of transition with the mounting holes on the top of the hood.
Fasten transition to hood using four (4)1 ⁄4’’ (6 mm) sheet metal screws included with hood.
Seal connection between transition and hood with aluminum tape. DO NOT use duct tape. Ensure that the connection is completely sealed.
Remove tape holding damper closed.
Remove the duct knockouts using a lat blade screwdriver and a small hammer. Take care of sharp edges.
Install strain relief (not included) into the circular knockout.

If it is not possible to vent cooking fumes and vapors to the outside, the hood can be used in the non-vented (recirculating) version, using the recirculating kit.
Fumes and vapors are recycled through the round grid.

Before installing the recirculation kit
The Installation of the Recirculation kit affects the installation of the hood, so take into consideration the following steps.

Cabinet or soffit preparation when installing the recirculation kit.
For cabinet or soffit preparation take into consideration that there’s no need to provide cutouts on walls for vertical or rear air discharge, since there is no need to install any Duct.
NOTE: Check that there is enough clearance and that minimum height from the countertop to the bottom of the hood is 30” (76.2 cm).
NOTE: The transition must not be installed, since no ducting is necessary.

Wall Mount Installation
First install deflector on top of the hood then install to the wall:

Fit four screws C on bottom of the deflector, do not tighten completely.
Install the deflector on top of the hood so that screws C go respectively into Side Slots on top of the hood and Side Slots on bottom of Deflector, slide Deflector frontward until stops.
Tighten the four screws C from inside of the hood.
Fit screws (dim:3.5×9.5), from inside the hood to final assembly Deflector to the hood (number depends on hood size).
Proceed to install hood as described on Wall Mount Installation described at the Hood Installation Manual.

Charcoal filter
In the recirculating mode, the air will be recirculated through disposable charcoal filters that help remove smoke and odors.

Remove the grease filter of the hood.
Cover the grill that protects the suction motor with the charcoal filter so that the slots on the filter correspond to the pins on the sides of the motor protection grill.
Turn the carbon filter clockwise to block them (bayonet fixing).

NOTE: The charcoal filters cannot be cleaned. It should be replaced every 4-6 months (depending on hood usage)
