Marchal Truma Straight Heater Vent Adaptor

Direct the Heat. Elevate Your Comfort.

Conceived, Designed & Made in the USA.

Take greater control of your camper's heating system with the Marchal Truma Heater Vent Adapter. Thoughtfully engineered to redirect warm airflow and expand your heating possibilities, this purpose-built upgrade brings added versatility to your existing Truma heater.

Designed to integrate with the heater's original moldings, the adapter delivers a clean, secure fit without screws, drilling, or permanent modifications.

The integrated connection accommodates standard 3-inch ducting commonly used with diesel heaters, allowing you to direct warm air toward other areas of your camper, including elevated sleeping spaces.

Engineered with Purpose

• Targeted Heat Distribution: Redirect warm airflow toward your camper's interior or connect ducting to reach additional areas.

• Custom-Fit Design: Engineered to integrate with the existing moldings of your Truma heater.

Important Installation Information

Proper duct routing is essential. Avoid kinks, sharp bends, or restrictions that could create backpressure and trigger errors in your Truma heater. While the 90° elbow adapter has been tested without causing heater errors, additional bends or improper duct positioning may affect airflow.

Manufacturing Note

Each adapter is produced using 3D-printing technology. Minor surface variations are a natural part of the manufacturing process, particularly in areas requiring print supports.

The base of both adapter configurations may have a slightly less smooth finish. The 90° elbow may also feature subtle surface swirls along the top and underside of the duct connection. These variations are cosmetic, do not affect intended functionality, and are generally concealed once ducting is installed.
