    I assume what you

    are looking for is the termination of the flue exhaust and the fresh air intake for your unit? The snow fall thing is designed to insure the exhaust and intake are above the average snowfall for your area.

    If you are a homeowner then your installer should handle that for you. If you are a contractor check with your local weather bureau.

    make sure

    Like Tim said, that is, the installers responsibility...I will also add this, confirm with the manufacture they allow snorkel kits, if needed,some do, some don't...You may not like the looks...Finding the proper vent location is very important...Ja
