Outside Combustion Air - Napoleon NZ6000-1 Installation And Operating Instructions Manual

3.2

OUTSIDE COMBUSTION AIR

NOTE: Incorporate a vertical loop or trap into air
liners to reduce air fl ow when appliance is not in
use.
Insulating the intake liners is recommended in colder
climates to prevent condensation from occurring.
The Napoleon Model NZ6000-1 takes outside air
directly into the appliance through the openings in the
left and right hand sides.
Decide on the most convenient location for the fresh
air inlet ducts and hoods which may be installed
above or below fl oor level.
The fresh air inlet ducts and hoods must be installed.
Secure and seal the intake liners to the collars using
3 sheet metal screws, and high temperature sealant.
Vertical rise is between:
6' (1.8m) & 10' (3m) max
3' (0.9m) & 6' (1.8m)
1' (0.3m) & 3' (0.9m)
0' (0m) & 1' (0.3m)
Included with the appliance are:
- Two 10' (3m) lengths of vent. Use a connector and seal if adding
more length.
- Two of intake hoods.
The vertical height of the air intake liner must not be greater than 2/3
the height of the chimney. If additional liner length is required, it may be
doubled by increasing the size from 6" (152mm) diameter to 8" (203mm)
diameter. Use a 6" (152mm) to 8" (203mm) increaser at the hood and
a decreaser at the appliance. Values in brackets represent 8" (203mm)
diameter intake liners.
The duct terminations must be located so they can not be blocked (i.e. snowdrifts). 4' (1.2m) above grade is
recommended. Make a 6 ½" (165mm) 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.
Horizontal run may be:
5' (1.5m)
15' (4.6m)
20' (6.1m)
