Hot Air Ducting

The Truma Combi units user 65mm hot air ducting as described in the installation manual, and the 65mm is referenced throughout. Uncommon knowledge is that Truma is referencing the outside diameter of the tubing and not the industry standard inside diameter. 65mm outside diameter is 60mm inside diameter. This is the same tubing as Webasto heater would use and is readily available from sellers in your State or Province. If you are looking for a source, we recommend Sure Marine, where you can purchase the tubing in 10' sections and all required accessories (elbows, fittings, etc) in one spot.
