Bosch DWA064W50B, Instructions For Installation And Use Manual

10

Room air-dependent heat-producing 

appliances (e.g. gas, oil, wood or coal-

operated heaters, continuous flow heaters 

or water heaters) obtain combustion air 

from the room in which they are installed 

and discharge the exhaust gases into the 

open air through an exhaust gas system 

(e.g. a chimney).
In combination with an activated vapour 

extractor hood, room air is extracted from 

the kitchen and neighbouring rooms - a 

partial vacuum is produced if not enough 

fresh air is supplied. Toxic gases from the 

chimney or the extraction shaft are sucked 

back into the living space.

■

Adequate incoming air must therefore 

always be ensured.

■

An incoming/exhaust air wall box alone 

will not ensure compliance with the limit.

Safe operation is possible only when the 

partial vacuum in the place where the heat-

producing appliance is installed does not 

exceed 4 Pa (0.04 mbar). This can be 

achieved when the air needed for 

combustion is able to enter through 

openings that cannot be sealed, for 

example in doors, windows, incoming/

exhaust air wall boxes or by other technical 

means.

In any case, consult your responsible 

Master Chimney Sweep. He is able to 

assess the house's entire ventilation setup 

and will suggest the suitable ventilation 

measures to you.
Unrestricted operation is possible if the 

vapour extractor hood is operated 

exclusively in the circulating-air mode.

Danger of death!

Risk of poisoning from flue gases that are 

drawn back in. If installing a ventilation 

system in a room with a heat-producing 

appliance connected to a chimney/flue, the 

electricity supply to the hood must be 

equipped with a suitable safety switch.

Risk of fire!

Grease deposits in the grease filter may 

catch fire. The specified safety distances 

must be observed in order to prevent an 

accumulation of heat. Observe the 

specifications for your cooking appliance. If 

gas and electric hobs are operated 

together, the largest specified distance 

applies.
Only one side of the appliance may be 

installed directly next to a high-sided unit or 

a wall. The distance between the appliance 

and wall or high-sided unit must be at least 

50 mm. 

Risk of injury!

■

Components inside the appliance may 

have sharp edges. Wear protective gloves.

Risk of injury!

■

The appliance may fall down if it has not 

been properly fastened in place. All 

fastening components must be fixed firmly 

and securely.

Risk of injury!

■

The appliance is heavy. To move the 

appliance, 2 people are required. Use only 

suitable tools and equipment.

Risk of electric shock!

Components inside the appliance may have 

sharp edges. These may damage the 

connecting cable. Do not kink or pinch the 

connecting cable during installation.

Risk of electric shock!

It must always be possible to disconnect 

the appliance from the electricity supply. 

The appliance must only be connected to a 

protective contact socket which has been 

correctly installed. If the plug is no longer 

accessible following installation of the 

appliance, or a fixed connection is required, 

an all-pole isolating switch must be present 

on the installation side with a contact gap of 

at least 3 mm. The fixed connection must 

only be installed by an electrician.

Danger of suffocation!

Packaging material is dangerous to 

children. Never allow children to play with 

packaging material.
