Vermont Casting 2490 Prefabricated Chimneys, Chimney Size, Chimney Connector Guidelines, 2000893

Unused openings in an existing masonry chimney must be sealed with masonry to the thickness of the chimney wall, and the chimney liner should be repaired. Open- ings sealed with pie plates or wallpaper are a hazard and should be sealed with mortar or refractory cement. In the event of a chimney fire, flames and smoke may be forced out of these unused thimbles.

The chimney should be thoroughly cleaned before use.

A newly-built masonry chimney must conform to the standards of your local building code or, in the absence of a local code, to a recognized national code. Masonry chimneys must be lined, either with code-approved ma- sonry or precast refractory tiles, stainless steel pipe, or a code-approved, “poured-in-place” liner. The chim- ney’s clean-out door must seal tightly to help ensure a good draft.

Prefabricated Chimneys

A prefabricated metal chimney must be one tested and listed for use with solid-fuel burning appliances to the High-Temperature (H.T.) Chimney Standard UL-103- 1985 (2100°F.) for the United States, and High Temper- ature (650°C) Standard ULC S-629 for Canada.

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

Chimney Size

A Resolute Acclaim is approved for venting into a masonry chimney with a flue size of 8” x 8” (203 x 203 mm), and into a round flue size of 8” (203 mm) or 6” (152 mm).

It may be vented into larger chimneys as well. How- ever, chimneys with liners larger than 8” x 12” (203 x 305 mm) may experience rapid cooling of smoke and reduction in draft, especially if they are located out- side the home. These large chimneys may need to be insulated or to have their flues relined for proper stove performance.

Accessories to help make the connection between stainless steel chimney liners and your Resolute Ac- claim are available through your local dealer.

Chimney Connector Guidelines

A chimney connector is the double-wall or single-wall pipe that connects the stove to the chimney. The chim- ney itself is a masonry or prefabricated structure that encloses the flue. Chimney connectors are used only to make the connection from the stove to the chimney. They are for interior use only.

Double-wall connectors must be tested and listed for use with solid-fuel burning appliances. Single-wall con- nectors should be made of 24 gauge or heavier steel, and should be 6” (152 mm) in diameter. Do not use

Resolute Acclaim Woodburning Stove

galvanized chimney connector; it cannot withstand the high temperatures that can be reached by smoke and exhaust gases, and may release toxic fumes under high heat.

If possible, do not pass the chimney connector through a combustible wall or ceiling. If passage through a com- bustible wall is unavoidable, refer to the recommenda- tions in the section following on Wall Pass-Throughs.

Do not pass the connector through an attic, a closet or any similar concealed space. The whole chimney con- nector should be exposed and accessible for inspection and cleaning.

Install the chimney connector not less than 23” (584

mm)from the ceiling. Keep it as short and direct as possible, with no more than two (2) 90° turns. If pos- sible, use 45° elbows. Slope horizontal runs of con- nectors upward 1/4” per foot (20 mm per meter) going from the stove toward the chimney. The recommended maximum length of a horizontal run is 3’ (914 mm), and the total length of chimney connector should be no longer than 8’ (2.5 m).

In cathedral ceiling installations, extend the prefabricat- ed chimney downward to within 8’ (2.5 m) of the stove.

SAFETY NOTE: ALWAYS WEAR GLOVES AND PRO- TECTIVE EYEWEAR WHEN DRILLING, CUTTING OR JOINING SECTIONS OF CHIMNEY CONNECTOR.

Double-wall Chimney Connectors

The listing for the Resolute Acclaim in the U.S. and Canada includes use of double-wall chimney con- nectors that have been tested and listed for use with solid-fuel burning appliances by a recognized testing laboratory.

Information on assembling and installing double-wall connectors is provided by the manufacturer of the double-wall pipe. Follow the manufacturer’s instructions exactly as you assemble the connector and attach it to the stove and chimney. Using chimneys and connectors from the same manufacturer helps make the assembly and installation straightforward.

NOTE: For installations using double-wall connec- tors, minimum clearances must conform to the listed clearances in the clearance chart on Page 8.
