Outside Combustion Air - Napoleon HIGH COUNTRY 3000H Installation And Operation Manual

3.2

outside combustion air

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.
