How must the exhaust duct of my Truma heater be installed and what needs to be considered with the exhaust gas system?

Exhaust ducts must always be laid rising from the Truma heater towards the cowl.

If the exhaust gases from your Trumatic S still pass through an aluminium pipe, replace this with a stainless steel pipe.

How to tell the difference:

When you remove the cover, you see a short exhaust duct. If the exhaust duct has a coil, it is stainless steel. If it does not have a coil but only has small grooves, it is made from aluminium and must be replaced.

Please note that the pipe must be replaced by an expert (e.g. Truma service partner).
