Outside Combustion Air; Hearth Extension - Napoleon NZ-26 Installation And Operating Instructions Manual

3.2

OUTSIDE COMBUSTION AIR

Model NZ-26 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 louvres
or a combination of both.
If the optional fresh air kit (available through your
authorized dealer) is installed, it must not draw air from
the attic or garage. It may only come from outside the
house. The maximum length of the 4" air duct is 20 feet;
thereafter enlarge the duct to a 6" diameter.
Decide on the most convenient location for the fresh air inlet duct and hood which may be installed above or
below fl oor level.
Make a 5" hole in an outside wall of the house. From outside, place the fresh air hood into the hole, open side
down.
At each end, carefully pull back the insulation sleeve exposing the fl exible duct. Place the insulated fl exible
duct over the fresh 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.
For outside air only, re-install the inside air cover plate to cover the control box inside air opening. See "COM-
BUSTION AIR CONTROL" section.
A chimney venting the appliance shall not vent any other appliance.

HEARTH EXTENSION

HEARTH EXTENSIONS ARE TO BE INSTALLED ONLY AS DESCRIBED TO PREVENT HIGH
TEMPERATURES FROM OCCURRING ON CONCEALED COMBUSTIBLE MATERIALS. HEARTH
EMBER STRIPS PREVENT BURNING OR HOT PARTICLES FROM INADVERTENTLY FALLING
DIRECTLY ON COMBUSTIBLE SURFACES IN THE EVENT THE BUILDING SHOULD SETTLE AND
In the USA, a non-combustible (ie.brick, stone or ceramic tile) hearth extension must be installed projecting 16"
from the front and 6.75" from the sides of the appliance.
In Canada, a non-combustible (ie.brick, stone or ceramic tile) hearth extension must be installed projecting 18"
from the front and 8" from the sides of the appliance.
Ensure that the gap between the appliance and a factory-built hearth extension is sealed with sand/cement
grout or covered with a metal strip (or both) to prevent sparks and embers from falling into this area. A raised
hearth together with the appliance built on a raised platform is recommended for easier wood loading and fi re
viewing.
