Hi Francesca,
High/low venting is about attempting to get rid of the excessive moisture (and other nasty by products) that an unvented combustion heater is going to create inside an RV.
Suz had blue flame and didn't like it, not a catalytic.
I am not interested in becoming a Darwin award winner, and my daughter is a CO survivor. I will not use an unvented combustion heater while I sleep.
Where I full time (we get to -40), it would be impossible to go all night without heat because of water lines freezing. There is a good chance the waste tanks would freeze, too.
I also refuse to use a generator while sleeping. These actions are too much of a gamble for me.

I think of the high/low venting as at least partly for air movement/circulation.
Do keep your own experience with the Wave in mind...sounds like you "survived" all right, as have thousands of other users that know how to follow the simple venting requirements.
I'm also a member of that group- now on my second (a Wave) due to having somehow damaged the face of the blanket on the one I'd been using for five or six years.
