OUTSIDE COMBUSTION AIR MANTEL CLEARANCES

Model NZ-26 has 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 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

flexible 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 fireplace shall not vent any other appliance. A chimney venting the fi replace shall not vent any other appliance.

Mantel clearance can vary according to the mantel depth.

HEARTH EXTENSION

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.

!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.

CHIMNEY INSTALLATION

!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.

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.

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 fireplaces 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.
