Outside Combustion Air - Napoleon High Country NZ3000 Installation And Operating Instructions Manual

3.2

OUTSIDE COMBUSTION AIR

Model NZ3000 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" air duct is 20
feet; for greater lengths enlarge the duct to a 6" diam-
eter.
Decide on the most convenient location for the out-
side 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" 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 con-
nector. 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 put-
ting 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.
