Model NZ-26 has the option of taking outside air directly into the
fi replace 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 fi replace outside air connector. Carefully push the insula-
tion sleeve back over the duct. Using 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 fi
replace shall not vent any other appliance.
A chimney venting the fi replace shall not vent any other appliance.

A chimney venting the fi replace shall not vent any other appliance.
The minimum overall chimney height from the top of the fi replace
is 11 feet.
The maximum overall chimney height from the top of the fi replace
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 fi replace is located. This enclosure must have a fi re resistance
rating equal to or greater than that of the fl oor or roof assembly
through which they pass.
CHIMNEY INSTALLATION
If the chimney system is enclosed within the attic area, a rafter radia-
tion shield is required.
The chimney must extend at least 3 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 corro-
sion.
The chimney must be supported at a maximum of 20 foot intervals
(approx. 200 lbs/20 ft).
The NZ-26 was tested to CAN/ULC S610 and UL 127 Factory Built
Fireplace Standards. This fi
replaces has met the test criteria for
Zero Clearance Installation to Combustible Surfaces and Certifi ed
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 CAN/ULC-S609 and ULC-S629 for Canada
or UL-103HT 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 mecha-
nism. Use the high temperature gasket, supplied, to seal between
the anchor plate and the fi replace top.
FIGURE 10
An acceptable 16" x 50" non-combustible (i.e.: brick, stone or ceramic
tile) hearth extension must be installed. Ensure that the gap between
the fi replace 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 fi replace built on a raised platform is recommended for easier
wood loading and fi re viewing.
Mantel clearance can
vary according to the
mantel depth.
!
WARNING
Hearth extensions are to be installed only as described to prevent
high temperatures from occurring on concealed combustible ma-
terials. Hearth sealing strips prevent burning or hot particles from
inadvertently falling directly on combustible surfaces in the event
the building should settle and disturb the original construction.
!
WARNING
Never install a single wall slip section or smokepipe in a chase
structure. The higher temperature of this single wall pipe may
radiate suffi cient heat to combustible chase materials to cause
a fi re.
To avoid danger of fi re, all instructions must be strictly followed,
including the provision of air space clearance between chimney
system and enclosure. To protect against the effects of corrosion
on those parts exposed to the weather, we recommend that the
chase top be painted with a rust-resistant paint.
Maintain a minimum 2" air clearance to all parts of the chimney
system at all times. Failure to maintain this 2" air clearance will
cause a structure fi re.
Detailed instructions for installation of the chase top, storm collar
and termination cap are packaged with these parts.
Firestop spacers must be used whenever the chimney penetrates
a ceiling/fl oor area.
