3.3.2. Output pipe
Damp air should be channelled to the outside by connecting a pipe with a net diameter equal to the exterior
diameter of the steam output pipe. The extraction air should be taken outside the premises and must never
be connected to other fluepipes already in use for removing vapours from other fuels.
The location of these pipes must be within the limits established in the environmental heat legislation. A
pipe made of heat-resistant material should be used (302ºF (150 ºC)). Never leave the tube very near
inflammable materials or materials that are susceptible to deformation from excessive temperatures.
The tube must be smooth inside. It is important that there are no obstructions blocking the air flow or that
may result in a build-up of fluff (bolts, rivets,...). Systems for the regular inspection and cleaning of the
pipes should be set in place.
The output pipe should be as short as possible and there should be a slope of 2% towards the outside in
the horizontal sections, to prevent condensation from returning to the machine.
Although the appliance has two dryers which operate independently, there is only one steam output.
The machine has a non-return valve which prevents steam from passing from one drum to the other. The
steam output can be connected directly upwards (advisable) or, if this is not possible, using a 90º (1.57
rad) L-bend to the back.
Option of the 90º (1.57 rad) L-bend
Option of the vertical output
