5 Assembly

Purpose of this section

This section provides detailed information on the assembly steps required for the stacking kit.

This section is intended exclusively for installers and authorized customer service companies.

Prerequisites

The following prerequisites must be met:

■

You have read and understood the 'For Your Safety' section.

5.1 Installing the Exhaust Duct Extension on the Bottom Unit

Checking the exhaust duct projection

Use the caliper or a measuring tape to measure the pro‐ jection at the lowest point of the exhaust duct located at the rear right of the unit’s top panel.

6.10/10.10: one exhaust duct

6.20/10.20: two exhaust ducts Make sure that you measure the distance between the exhaust duct and the actual top panel (do not start meas‐ uring from the black gasket)

If the height exceeds 0.6”, the exhaust duct extension does not need to be installed.

If the height is less than 0.6”, the exhaust duct extension needs to be installed.

Checking the exhaust duct’s chamfer

Insert the enclosed exhaust duct extension into the ex‐ haust duct.

Check to make sure that the chamfers match.

5 Assembly

Page 33

Installing the exhaust duct extension

Clean the inside of the exhaust duct as far as you will be inserting the exhaust duct extension.

Clean the outside of the exhaust duct extension.

Apply a bead of high heat silicone all around the bottom of the exhaust duct extension.

Insert the exhaust duct extension into the exhaust duct.

5 Assembly

Page 34

Slide the exhaust duct extension as far as it will go into the exhaust duct.

Wipe off the excess silicone.

Check to make sure that the gap between the exhaust duct extension and the exhaust duct is completely filled with silicone.

Check to make sure that the exhaust duct extension is centered inside the exhaust duct.

If possible, let the silicone cure before installing the ac‐ cessories!

If you lift the accessories after assembly (before the sili‐ cone has cured), make sure to check once again that the exhaust duct extension is in the correct position.

5 Assembly

Page 35

5.2 The bottom combi oven is mounted on the base

The figures below show a stacking kit for gas units. They are used as an example representing all unit sizes and unit models.

Preparing the bottom unit

Make sure that the bottom unit’s oven cavity is empty (re‐ move the racks, suction panel, sheet pans, etc.).

Lift the bottom unit off from the shipping pallet.

6.10/10.10: There must be at least four people available

6.20/10.20: There must be at least eight people available

Remove all screws from the shipping pallet.

4.a

With several people, carefully place the bottom unit on its back side on the shipping pallet.

To prevent damage to the rear panel, use a suitable sur‐ face (e.g., cardboard divider and styrofoam board from the packaging) to protect the unit.

Do not lift or carry too much weight during the process! Caution: Risk of injury due to excessive exertion!

4.b

In the case of units with a disappearing door, make sure not to damage the black block on the side!

5 Assembly

Page 36

5.a

Stacking kit with 6” or 12” base height Place the stacking kit base at the intended installation lo‐

cation and use a spirit level to level it by adjusting the feet.

5.b

Stacking kit with rollers (4” or 6” base height) Use the nuts included with the installation kit to install the

rollers on the stacking kit’s base (long rollers (1) in the back, short rollers (2) in the front). Place the base with rollers at the intended installation lo‐ cation and use a spirit level to level it

You can replace the small rollers with the big ones as necessary (in the back or front) in order to level the base.

Remove the four feet.

Safely store the flat washers. You will be reusing them later.

5 Assembly

Page 37

Before starting to fasten the base, remove the two retain‐ ing screws for the left side panel at the bottom of the unit.

Install the water distributor, hoses, tubes, gas angle bracket, and cleaning agent lines as applicable.

Fastening the base

Stacking kit with 6” or 12” base height

1.a
