Model NZ3000H has the option of taking outside air
directly into the appliance through the opening on the
left hand side or taking inside air through the lower
front grille or a combination of both. For inside air,
push in the control slider.
If the optional outside air kit (available through your
authorized dealer) is installed, it must not draw air
from the attic or garage. For outside air, pull out the
air control slider. It may only come from outside the
house. The maximum length of the 4"(101.6mm) air
duct is 20 feet (6m); for greater lengths enlarge the
duct to a 6"(152.4mm) diameter.
Decide on the most convenient location for the
outside air inlet duct and hood which may be installed
above or below fl oor level but must be installed above
grade level.
Make a 5"(127mm) hole in an outside
wall of the house. From outside, place
the outside air hood into the hole, open
side down.
At each end, carefully pull back the
insulation sleeve exposing the fl exible
duct. Apply sealant to both the outside
air hood collar and the connector collar
at the appliance. Place the insulated
fl exible duct over the outside air hood
and over the appliance outside air
connector. Carefully push the insulation
sleeve back over the duct.
Using the clamps, fasten the insulated
duct into place on both sides.
Cold air fl ow can be minimized by
putting a dip or loop in the duct
creating a cold air trap. This trap can
also help prevent heat build-up and
exhausting out the intake due to stack
effect. The outside air kit inlet should
be positioned in a manner that will
not allow snow, leaves, etc. to block the inlet. In
some installations the air duct may need to be run
vertically.
NOTE: Appliance must be set for inside air if
outside air is not connected.
