Room ventilation

The room ventilation at the operating location of the kiln includes both the supply air and the exhaust air.
9.6.1.

Supply air at the operating location

⇒ Sufficient room ventilation (supply air) at the operating location must be ensured.
⇒
This can be provided via window ventilation - which means that it must be ensured that the window is always
open during the firing process (by installing a window contact switch).
⇒ If window ventilation is not possible, the fresh air supply must be ensured via a separate ventilation system.
⇒
The heat loss from the kiln casing should be taken into account when designing the room ventilation (supply air
and exhaust air).
⇒
Ask a ventilation technician or chimney sweep about this.
9.6.2.

Exhaust air at the operating location

⇒
The kiln always generates a certain amount of exhaust gas during firing.
⇒
Exhaust gases are generated with every firing process, regardless of
•
whether it is a biscuit or glaze firing,
• the type of clay or glaze,
•
or the manufacturer.
⇒
These exhaust gases contain, for example, carbon monoxide, nitrogen oxides, sulphur oxides, fluorine
compounds and carbon dioxide from organic admixtures in the glazes or ceramic masses.
⇒
Exhaust gases are potentially hazardous to health and corrosive.
⇒
They should be properly discharged from the operating location.
⇒ The flue pipe is connected either via an exhaust air socket on the kiln (included in the scope of delivery) or via a
full-surface exhaust air hood over the kiln (optionally available).
⇒ In both systems, the connection is made via an air vent opening, i.e., the exhaust gas is diluted with room air and
cooled.
⇒
The exhaust air from the kiln rises into the exhaust air socket and takes some of the ambient air with it.

⇒
It is possible to attach a pipe to the exhaust air socket to discharge the exhaust air.
⇒
Either a flexible aluminium pipe (ø 70 mm, optional accessory) or a fixed pipe can be attached to the exhaust air
socket.
⇒
Ask a ventilation technician or chimney sweep about this.
⇒ The exhaust air mixes with the ambient air and "sucks" it into the pipeline. Mixing cools the hot exhaust air.
⇒ If an exhaust air system is installed by an external company, it must be ensured that the exhaust air pipe is not
mounted directly on the kiln.
