Exhaust ducting
The exhaust ducting for the flatwork ironer must not be chan-
nelled into a chimney or flue already in use for any gas-, coal- or
oil-burning appliance. It must also be laid separately to any exhaust
air duct used for a tumble dryer.
The moist-warm exhaust air is to be conducted to the outside or into
a suitable venting duct over the shortest path possible. Due to the
higher air velocity, the exhaust ducting must be laid in such a way
that air flow is not hindered (few bends, short lines, well-made con-
nections and transitions). Filters and louvres may not be installed in
the exhaust ducting.
Since the relative humidity can amount to up to 100%, suitable meas-
ures must be taken to prevent condensate from flowing back into the
ironer. If the machine fan is not powerful enough to remove the moist
air, a suitably powerful additional fan must be installed in the shaft or
roof outlet on-site. Supply air must be provided to the room of install-
ation according to the amount of exhaust air.
- The connection for the exhaust air ducting for vapour extraction is
located on the rear of the left side column and has a diameter of
70mm (HTDN70).
- The exhaust ducting must have an internal diameter of 70mm
(HTDN70).
- If the exhaust ducting rises upwards, a condensate drain hole with
a diameter of 3–5mm must be provided at the lowest point.
- Adequate ventilation of the installation room must be ensured.
- The ducting system and the exit point to the outside must be
checked on a regular basis for a build-up of lint and cleaned if re-
quired.
- The end of ducting leading into the open should be protected
against the elements, e.g. with a downward facing 90° bend.
