Stardance Natural Vent

Certiﬁed to:

ANSI Z21.88-2005 / CSA Z2.33-2005

Vented Gas Fireplace Heaters

The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 - latest edition. (EXCEP- TION: Do not derate this appliance for altitude. Main- tain the manifold pressure at 3.5” w.c. for Natural Gas and 10” w.c. for Propane.)

High Elevations

Input ratings are shown in BTU per hour and are certiﬁed without deration for elevations up to 4,500 feet (1,370m) above sea level.

For elevations above 4,500 feet (1,370m) in USA, installations must be in accordance with the current ANSI Z223.1/NFPA 54 and/or local codes having jurisdiction.

In Canada, please consult provincial and/or local authorities having jurisdiction for installations at elevations above 4,500 feet (1,370m).

WARNING: Improper installation, adjust- ment, alteration, service or maintenance can cause injury or property damage. Refer to this manual for correct installation and operational procedures. For assistance or additional information consult a qualiﬁed installer, service agency, or the gas supplier.

Venting Requirements and Options

The Stardance must be properly connected to a listed 4” (102 mm) Type B venting system or to an approved Class A masonry or factory-built chimney system. In Canada, a complete relining of Class A chimney sys- tems is required.

The Stardance Natural Vent stove will accept decora- tive 6” (152 mm) stove pipe around the Type B venting system, for aesthetic purposes.

Complete Type B vent systems are available from a number of manufacturers, and your dealer can usually supply one. Pipe sections from different makers are not interchangeable; do not mix pipe or vent sections from different makers. Follow the vent system manufactur- er’s instructions.

The vent system should conform to the speciﬁcations of the National Fuel Gas Code, latest edition.

If connecting to a Class A chimney system, use 4” (102

mm)single wall or 4” Type B vent connector. Single wall vent connector requires a minimum 6” (152 mm) clear- ance to combustible surfaces.

Exterior chimneys may be subject to ﬂow reversal or condensation. To lessen these conditions, enclose Type B vents in an insulated chase, or reline exterior Class A chimneys.

An approved pass-through device is always required, whether the vent system passes through a wall or

a ceiling. Use a pass-through device from the same maker who supplies the venting system.

Venting terminals shall not be recessed into a wall or siding.

Vent Layout and Height Requirements

Venting for a Stardance can rise vertically through the home, or can pass through an exterior wall and rise along the outside of the home. Some codes require that a Type B vent system rising on the outside of the home be enclosed in a chase. Check your local codes for requirements.

The minimum vent system height for the Stardance Natural Vent Stove is 8’ (2.43 m), (Fig. 7) measured from the top of the stove. To determine the minimum height the vent system must extend through or past the roof, refer to the 1993 edition of the National Fuel Gas Code.
