OK David,Your option is to reduce the nozzle size and sacrifice some Batu's in the high elevations.It's a shame the didn't build an air adjustment into this unit. I guess they think everybody lives at sea level. Is your nozzle accessible without tearing the whole unit out?If you can tell me the nozzle size and degree I can put you in the ballpark on a smaller size.Nick-
Thanks Tq. I'll mention that to Mr. Edwards.Nick, The webasto tech named Gilbert, that I spoke with on Dec 19, said there is no way to change fan speed on this model. Unfortunately, that is not an option on the DB 2010. He suggested I buy a bigger unit. Yea, right. David
It wasn't an extra 22', just an extra 11'. My stock length is 11' with 139 degrees of bends.David
Brian,What size is your exhaust pipe and how long and how many bends? Mine is 1 1/2" x 11' with 130* bends. I'm thinking about upsizing to 2" x 5' with one 90* bend, inconvenient for the bay doors, but should eliminate any airflow issues.David
