CONSIDERATIONS BEFORE INSTALLING HOOD

1. For the most efficient air flow

exhaust, use a straight run or as

few elbows as possible.

CAUTION: Vent unit to outside

of building, only.

2. Do not use flex ducting.

3. COLD WEATHER installations

should have an additional

backdraft damper installed to

minimize backward 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.

4. Hood installation height above

cooktop is the users preference

The closer the hood is to the

cooktop the more efficient it will

be in capturing of cooking odors,

grease and smoke. Be sure the

hood model fits your installation.

PREPARATION OF

MOUNTING SURFACE

1. A) Select a hood installation height P

above the cooktop that is comfortable

for the user.

Thermador recommends a distance of

30-36 between the countertop and

bottom of the hood.

B) Compute the hood height H by

using Fig. A. If the hood height is out

of the range specified in table 1 select

a new installation height P.

C) Calculate chimney structure

height B by using formulas in Fig.

A and dimensions in Table 1.

Note: Take into consideration the

hood depth; some models are

much deeper than the cooktop.

2. Mark center lines of cooktop or

range on ceiling above. Use

centerlines marked on ceiling to

position the mounting template.

Note location of hood front side

and mounting holes indicated on

template.

3. Remove and save template. Cut and

remove ceiling drywall. Install suitable

length 2" x 4" lumber between joists

to provide chimney mounting points

as shown in Fig. C and D. Use

template for dimensions and required

clearance.

HTDI

Fig. C

Fig. D

Note the weight of the appliance

(see Table 1). Make sure to affix the

added lumber firmly and level. Consult

a professional if you have difficulties

or your installation is unique. Consult

template and Figs. B. C. D.

4. REMOTE VENTILATOR AND DUCT

INSTALLATION. Refer to

instructions shipped with remote

ventilator model VTR1000Q or

VTR1400Q for installation of remote

blower and ducting. The remote

ventilator inlet fits 10 round duct.

Transition down to 8 round for

clearance in the chimney structure

shown in Fig. B. Female end shall be 4-

1/2" below finished ceiling and

securely fastened to joists.

Fig. B

HTNI HNI

Page 5

5. Install wiring for remote ventilator

and power supply. See electrical

Installation on page 9.

The conduit for the remote ventilator

and power supply must extend a

distance B (see Fig. A) from the ceiling

to reach the hood junction box.

6. Install drywall around duct and

conduit. Finish drywall surface to

match ceiling.

7. Tape mounting template to ceiling

using centerlines for alignment.

Appliance Installation: (Note:

three people may be required for

proper installation of HTNI, two

people for the HNI).

1. Install transition to top of hood

(if removed for shipping).

2. Adjust chimney mounting

structure to B dimension as

determined in Step 1, page 5.

Use 2 screws per attachment

leg. For HTNI

use a minimum

of 12 screws. See Fig. B. Do not

fasten to ceiling now.

3. Set chimney mounting structure

on top of hood canopy. Attach

nuts loosely. See Fig. F and G.

4. Fit duct piece on transition so

that top end is 5-1/2" below top

of chimney structure, male end

up.

5. Remove chimney structure from

hood canopy.

6. Install Ducting. For HNI

hoods fasten duct to transition

with screws and tape per code.

Loosely fasten starter collar

(included) flush to top of duct.

Fig. E

Fig. F

Fig. H

7. To install Chimney

Structure to

ceiling, use a

10mm or adjustable wrench or

flat head screwdriver. Drill

holes into ceiling. Attach

mounting structure to joists with

lag screws provided. (Keep

the 4

conduit inside structure.) See

1/2"

Fig. B.

8. Remove Chimney Cover's

plastic protective film.

Reassemble and fasten all 3

covers together with one

vertical screw. See Fig. E. Slide

over chimney structure and

secure with 2 screws near

ceiling.

9. To fasten the canopy use a

10mm or adjustable wrench.

Attach nuts (with washers on

HTNI) to top of canopy .

pilot

For HTNI hoods fasten duct to

ceiling with screws and tape per

code. Loosely fasten starter

collar (included) flush to bottom

of duct.

Page 6

Do not tighten. Raise canopy

up to chimney structure and

twist in place. See Fig. G.

Tighten nuts securely.

10. Ducting for all units: There

should be no more than 1" gap

between canopy ducting and

house ducting. Adjust starting

collar over both ducts. Tighten

collar. Fasten duct with screws

and tape per code. Make final

angular adjustment to unit at

ceiling if necessary, then securely

tighten 4 ceiling lag screws if not

already tightened. Chimney

cover must be lowered to do

this.

Gently slide the outer and

middle covers down and set on

canopy. Raise the middle cover,

align holes with lower cover and

insert pin or wire to temporarily

hold up. Fasten covers together

using 2 screws provided.

NOTE: Do not overtighten and

deform metal.

In model HTNI, if the hood

installation height H is less than

36-3/4", the middle cover will

not be raised. Instead the

middle cover is located behind

the bottom cover and no hori-

zontal screws are used.

11. To connect conduit and

wiring see Wiring section on

page 9. Then replace J-box

cover.

12. For final Chimney Cover

installation, DO NOT USE

ELECTRIC SCREW

DRIVER. Raise chimney covers

and fasten in place with 2 screws

if not already fastened. Fig. E.

Remove one vertical screw

holding covers together. See Fig.

Fig. I

13. In model HTNI fasten lower

chimney cover to canopy from

inside the hood with 8 screws

included. See Fig. I.

2 conduit from the remote

ventilator to the hood.

2. Install conduit connector at the

end of the conduit. Remove the

knockout on top of the junction

box. Attach conduit connector
