What's wrong?
On affected 2019-2021 Triple E Rv Wonder, S24CB, and Unity motorhomes, the propane supply line connects to the Truma water heater through a brass connector. That connector is supposed to join the flared propane line to the water heater swivel fitting and create a sealed path for propane going into the heater. The seal depends on the inside bevel matching the flare.
The wrong brass connector was installed. It has the same threads as the correct part, so it can screw into place, but the bevel inside the fitting is the wrong thickness. Because that bevel does not seat correctly against the Truma fitting, the joint does not seal the way it was designed to seal.
The warning sign is a propane smell near the Truma water heater. If you notice propane odor in that area, stop using the water heater and have the propane connection inspected before further use.
