[A/S] Furnace vents

["prairietex" <hilty@xxxxxxxxxxxxx>]

Hello everyone,

I have been absent, but occasionally lurking at the Yahoo Groups
website for sometime now. I have a question that maybe someone can
answer for me  since I do not have my Airstream manual handy. I have a
25' 1990 Excella with the suburban furnace mounted under the
range/oven on the curb side just aft of the door. There are three vent
holes on the exterior in that vicinity - a double set in a vertically
mounted plate and a single in a similar plate approximately 4"x4". My
question is where do these go, which is the intake and which is the
exhaust, why three (seems like they would need to be balanced)? Have
any of you had any experience with dirt dobbers, and how would I tell
if I had such a problem?

Thanks,
John Hilty
