1.­ Determine­the­best­location­for­the­vent­kit.
NOTE: Consider the following when determining the vent kit
location:
A. Vent kit positioned where the vent vapors will not damage
planting/ shrubs or air conditioning equipment or building
structure.
B. Vent kit positioned so it will not be affected by wind eddy
that may allow recirculation of combustion products, or air-
borne leaves, or light snow.
C. Vent kit positioned where it will not get damaged or be
subjected to foreign objects, such as stones, balls, etc.
D. Vent kit positioned where the vent vapors will not be ob-
jectionable.

NOTE: To prevent the possiblility of condenate freeze-up, do
not install vent kits one above the other.
NOTE: FLUE GAS DEGRADATION
The moisture content of the flue gas may have a detrimental
effect on some building materials. This can be avoided by
using the roof or chimney venting option. When wall venting
is used on any surface that can be affected by this mois-
ture, it is recommended that a corrosion resistance shield
(24 inches square) be used behind the Vent Terminal. This
shield can be made of wood, plastic, sheet metal, etc. Also,
silicone caulk all cracks, seams, and joints within 3 feet of
the Vent Terminal.
