Air Ducts - STIEBEL ELTRON LWZ 130 Bedienung Und Installation

INsTALLATIoN
Installation
f Connect a condensate hose to the condensate outlet of the f
condensate pump and route it into a drain. In order for the
condensate pump not to run dry, the condensate hose behind
the pump must not route directly downwards.
f Connect the power supply of the condensate pump. f

10.3 Air ducts

Material losses
!
Never link cooker hoods to the ventilation system.

!
During installation, ensure that no metal swarf enters
the pipework. However, should this occur, remove this
debris, otherwise the fans may be damaged.
Install the air ducts using materials that can be obtained from us
or with commercially available folded spiral-seam tubes.
10.3.1 Insulation against condensation
Material losses
!
When warm air meets cold surfaces, condensation can
result.
f For outdoor air and exhaust air ducts, use vapour f
proof thermally insulated pipes.
f If the supply and extract air ducts are routed f
through unheated rooms, insulate these ducts as
well.
10.3.2 Connecting air ducts to the appliance
You can connect air ducts with two different diameters to the
appliance.
Air ducts with diameter DN 125
f Push the air duct onto the air connection. f

f Secure the air duct at the appliance air duct connection with f
self-adhesive aluminium sealing tape.
Optional : Air ducts with diameter DN 150
You can obtain DN 150 air duct connectors from us as accessories.
f Remove the air duct connectors mounted in the delivered f
condition by undoing the screws.
f Screw the new air duct connectors onto the appliance. f
10.3.3 External wall ducts
Install the outdoor air intake into the building at a location where
contamination (dust, soot, odours, flue gas, exhaust air) is as low
as possible.
When installing external wall ducts, prevent any short circuit be-
tween the air intake and the air discharge.
10.3.4 Silencer
f Install a silencer in both the supply air duct and the extract f
air duct. Install these silencers as close as possible to the ap-
pliance, so that noise is suppressed at an early stage.
We recommend installing additional silencers if required to avoid
sound transmission.
If a room with a high noise level needs to be ventilated, install
additional silencers upstream of this room to reduce sound trans-
mission to the neighbouring rooms.
Aspects such as carried voices and impact sound must also be
taken into consideration in the case of ducts embedded in con-
crete. Carried voices should be avoided by designing the duct with
separate branches to the vents. If necessary, insulate the supply air
ducts, e.g. if they are mounted outside the insulated wall panel.
10.3.5 Overflow apertures
Living rooms and bedrooms are only supplied with air. Air is only
extracted from rooms where odours and moisture are generated.
Ensure an unimpeded overflow and consequently air balancing.
Install ventilation grilles in internal doors or walls, or enlarge the
air gap beneath the door to ≥ 8 mm.
10.3.6 Cleaning apertures
f Fit cleaning apertures when installing the air ducts, so that the f
air ducts can be inspected and cleaned at regular intervals.
10.3.7 Supply and extract air vents
Supply and extract air vents for the living space are available for
wall or ceiling mounting.
When venting the kitchen, ensure that the extract air vent is fitted
as far as possible from the cooker.
