OUTSIDE COMBUSTION AIR
Note: Incorporate a vertical loop or trap into air liners to reduce air flow when unit is not in use.
Insulating the in- take liners is recommended
in colder
climates to pre- vent condensa-
tion from occuring.
The Napoleon
Model NZ6000 takes outside air directly into the fireplace
through the openings in the left and right hand sides.
Decide on the most convenient lo- cation for the fresh air inlet ducts and hoods which may be installed above or below floor 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 | Horizontal |
rise is | run may be: |
between: |
|
6' & 10' max | 5' |
3' & 6' | 15' |
1' & 3' | 20' |
0' & 1' | 25' |
Included with the fireplace are:
- two 10' lengths of vent. Use a connector and seal if add- ing 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" diameter to 8" diameter. Use a 6" to 8" increaser at the hood and a decreaser at the fireplace. Values in brackets represent 8" diameter intake liners.
The duct terminations must be located so they can not be blocked (i.e. snowdrifts). 4' above grade is recommended.
Make a 6 ½" 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.
MANTLE CLEARANCES
An optional combustible mantle must be a minimum of 12" above the top of the faceplate and not to extend more than 2" from the surface. See chart below for further information.
