5.Avoid areas where condensate drainage may cause problems by dropping on plant- ers or patios, etc. Also ensure that ex- haust gases will not impinge on windows or building surfaces, which may be com- promised 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 termi- nate above any public walkways.

6.Select the point of wall penetration where the minimum 1/4 inch per foot of slope up can be maintained.

!CAUTION:

For optimal performance vent furnace through wall which experiences the least exposure to winter winds.
