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.

Figure 2: Typical Hood Installation

(83)

Cooking Surface

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.

MODEL WEIGHT

HPCN36NS 33 lbs. (15 kg) HPCB36NS 49 lbs. (22 kg) HPCN48NS 47 lbs. (21 kg) 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 5

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.

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.

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.

WARNING!

Vent ducting directly outdoors (not into an attic, underneath the house, into the garage or into any enclosed space).

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.

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.

Electrical Requirements

Hood Transition

CAUTION!

This range hood must be properly grounded. The unit should be installed by a qualified electrician in accordance with all applicable national and local electrical codes.

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.

Assembly of the Transition:

The overall height of the transition is 8Ǫ" (212 mm). The hood transition sits 6½” (165 mm) above the top of the hood. 1Ǭ" will mount below the top edge of the hood. See Figure 4 on page 9 for overall hood dimensions.

1. Align mounting holes at base of transition with the mounting holes of the ½” (13 mm) flange located at the top.

2. Fasten transition to hood using (4) 1” (25.4 mm) sheet metal screws, included with hood.

3. Seal connection between transition and hood with aluminum tape.

4. Remove tape holding damper closed.

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.

CAUTION!

To reduce the risk of fire and electric shock, install this range hood only with the blowers listed in Table 1.

WARNING!

Cutting the plug of the blower will void the warranty or eligibility for return or exchange.

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 airÀow exhaust, use a straight run or as few elbows as possible (refer to “Ductwork Preparation” on page 6).

IMPORTANT NOTE: Secure the Chimney Hood to the wall before installing the Chimney Extension. See “Hanging the Chimney Hood” on page 11 before securing the actual Extension.

1. Installation of the chimney hood should maintain a minimum height of 30" (762 mm) from the bottom of the hood to the cooking surface. To determine placement of the hood with a Chimney Extension, the height of the chimney extension must be calculated (see “Calculating Optional Duct Cover Height” on page 9).

2. From inside of hood, screw the supplied 5/8” (16 mm) sheet metal screws through the holes on each side and along the front into bottom of the extension, as shown in Figure 21. (Screw quantity is dependent on hood

size.)

IMPORTANT NOTE:

Secure the Chimney Hood to the wall after installing the Extension Mounting Bracket, but before installing the Telescoping Chimney Extension. See “Hanging the Chimney Hood” on page 11 before securing the actual Extension.

Securing the Telescoping Chimney Extension Bracket

1. Ensure that the minimum height of 30" (762 mm) from the bottom of the hood to the cooking surface will be maintained (see “Calculating Optional Duct Cover Height” on page 9).
