Default Exhaust/intake vent under a deck

I am looking for documentation on installation location of a vent (combination intake and exhaust) for a furnace under the deck.

I feel the exhaust could very easily be drawn back into the system with this set up.

Any ideas?

Thanks,

Rick in that location would you allow your dog to sit above or perhaps a child ?


7. Avoid areas where condensate drainage
may cause problems by dropping on planters
or patios, etc. Also ensure that exhaust
gases will not impinge on windows or building
surfaces, which may be compromised or
damaged by condensation. Do not install the
vent terminal such that exhaust is directed
into window wells, stairwells, under decks
or into alcoves or similar recessed areas,
and do not terminate above any public
walkways.

Bob and Wayne,

Thanks for the input. I did write it up for area above and carbon monoxide, the vulnerability of damage to the deck and the possibility of the exhaust being drawn back into the system. I am still trying to find some documentation somewhere to use as reference material.

If the deck is open (ventilated) on two sides it should be OK.
