OUTSIDE COMBUSTION AIR

Napoleon models NZ-26 & NZ-26WI have the option of taking
outside air directly into the fireplace 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 Napoleon
/ Wolf Steel Ltd. 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 inch air duct is 20 feet; thereafter
enlarge the duct to a 6 inch diameter.
Decide on the most convenient location for the fresh air inlet
duct and hood which may be installed above or below floor
level.
Make a 5 inch 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 expos-
ing the flexible duct. Place the insulated flexible duct over the
fresh air hood and over the fireplace outside air connector.
Carefully push the insulation sleeve back over the duct. us-
ing the clamps, fasten the insulated duct into place on both
sides. Figure 9.
For outside air only, re-install the inside air cover plate, shown
in Figure 37, to cover the control box inside air opening. See
Section on Combustion Air Control.
A chimney venting the fireplace shall not vent any
other appliance.
The minimum overall chimney height from the top of
the fireplace is 11 feet.
The maximum overall chimney height from the top of
the fireplace is 34 feet.
Factory-built chimney systems for use in dwellings
constructed for three or more families must be enclosed
above the room in which the fireplace is located. This
enclosure must have a fire resistance rating equal to or
greater than that of the floor or roof assembly through
which they pass.
If the chimney system is enclosed within the attic area,
a rafter radiation shield is required.
The chimney should not be built with an offset angle in
excess of 45° in Canada and 0° in uSA.
The NZ-26 & NZ-26WI were tested to CAN/uLC S610 and uL 127 Factory Built Fireplace Standards. These Fireplaces have
met the test criteria for Zero Clearance Installation to Combustible Surfaces and Certified to burn Firewood only.
Any 6" diameter chimney listed to these standards may be installed. In accordance with these standards, the unit may also
be connected to any chimney listed to uLC-S629 for Canada or uL-10HT for the united States.
Installation of all types of factory-built chimney systems is to be in accordance with the chimney manufacturers installation
instructions. An appropriate chimney manufacturers anchor base plate and anchor base plate gasket is required in order
to initiate the twist lock mechanism. use the high temperature gasket, supplied, to seal between the anchor plate and the
fireplace top.

ChIMNEY INSTALLATION

MANTLE CLEARANCES

Mantle clearance

can vary accord-
ing to the mantle
depth.
figure 10

hEARTh EXTENSION

An acceptable 16" x 50" non-combustible (ie: brick, stone
or ceramic tile) hearth extension must be installed. Ensure
that the gap between the fireplace 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 fall-
ing into this area. A raised hearth together with the fireplace
built on a raised platform is recommended for easier wood
loading and fire viewing.
The chimney must extend at least  feet above its point
of contact with the roof and at least 2 feet higher than
any wall, roof or building within 10 feet.
If the chimney extends more than 5 feet above the roof,
it must be secured using a roof brace or guide wires.
Ensure that minimum clearances are maintained
Portions of the chimney that extend through accessible
spaces must always be encased to avoid personal
contact with the chimney and thereby avoid damage
to the chimney.
A raincap must be installed to avoid internal damage
and corrosion.
The chimney must be supported at a maximum of 20
foot intervals (approx. 200 lbs/20 ft).
