3.2 OUTSIDE COMBUSTION AIR
EN Insulating the intake liner is recommended in colder
climates to prevent condensation from occurring.
The Napoleon Model NZ8000 takes outside air directly
into the appliance through the opening on the left side.
The fresh air inlet duct and hood must be installed lower
than the fi rebox. Secure and seal the intake liner to the
collar using 3 sheet metal screws, and high temperature
sealant.
The duct inlet must be located so they can not be blocked (i.e. snowdrifts). 12" (305mm) above grade is
recommended. Make a 4 ½" (114mm) inch hole to suit in an outside wall of the house. From outside, place the
fresh air hood into the hole, open side down. Seal with caulking and secure.
