Adam,

Questions specific to a particular converter are best answered by owners of the same type conversion, or better yet, the converter.

All our Webasto systems function in the same basic way, but what makes all but Marathon or marathon owners incapable of answering your question is the flow path and valving is likely unique to Marathon coaches.

I have been pushing for a future rally to have a large number of attendees so we can encourage converter specific seminars put on by the converter. Our Prevost chassis are all enough alike so we can help each other regardless of conversion.
