Lennox Hearth 1900HT-M Acceptable Connector Pipe for INSTALLA- Tions, Chimney Inspection

INSTALLATION

ACCEPTABLE CONNECTOR PIPE FOR INSTALLA- TIONS

For Standard Residential Clearances: Six (6) inch minimum, single wall, minimum MSG black or 25 MSG blued steel connector pipe with listed factory-built chim- ney suitable for use with solid fuels or masonry. Three

(3)pre-drilled holes are provided in the flue collar for fastening the pipe securely to the stove. Use sheet metal screws to do this. Additional sections of single wall pipe should be fastened together with at least three

(3)sheet metal screws each section. When connecting to the factory built ceiling support package, use the manufacturer's transition piece, usually called a dripless connector, to join single wall pipe to their factory built chimney section.

Minimum Flue Size - The required minimum diameter and area required for the flue size is (respectively) 6 inches / 152 mm diameter, which is approximately 28 square inches / 711 square mm. The maximum flue size should be no more than (3) three times the cross sectional area of the size of the 6 inches / 152 mm di- ameter flue collar. In this case, that would be no larger than a 10 inch (254 mm) diameter (area = approx. 85 sq. inches [216 sq. cm]).

Connection To A Factory Built Chimney - This space heater is to be connected to a factory-built chimney conforming to CAN / ULC – S629, Standard for 650°C Factory-Built Chimneys.

For Reduced Residential Clearances: Type L and listed double wall connector pipe is acceptable. Install any factory built brand of pipe according to the manu- facturer's instructions.

Vapor Barrier at Chimney Penetration

Install all venting components per the Vent Manufactur- ers installation instructions. Ensure that there is an ef- fective vapor barrier at the location where the chimney penetrates to the exterior of the structure. This can be accomplished by applying a non-hardening waterproof sealant to the following components:

•Around the chimney at the point where the storm collar will meet the chimney just above the Flash- ing.

•Along the vertical seam of the chimney pipe, where it is exposed to the weather.

•On each nail head on the flashing.

•Around the chimney at the point where the storm collar will meet the chimney just above the flashing.

Notes:

•On a flat or tarred and graveled roofs, nail and seal the flat roof flashing to the roof on all sides with roofing compound.

•Do not put screws through the flashing into the chimney pipe.

CHIMNEY INSPECTION

Existing chimneys must be inspected before installing your stove. Consult your local building department for chimney code requirements. A masonry chimney must have a code approved liner. This liner must not have broken or missing pieces. Some non-code masonry chimneys may be brought up to code by being relined. (Consult your dealer or qualified chimney sweep). Fac- tory built chimneys should also be inspected, first for creosote deposits (which should be removed), and then for integrity of the stainless steel liner.

Look for obvious bulges in the lining which may indicate the need to replace that section (use a bright flashlight). Also, inspect the attic to see that the chimney has proper clearance to combustible framing members. For interior masonry chimneys and most factory built chim- neys, this must be a (2) two inch air space clearance, which must not be filled with insulation or any other ma- terial. An exterior masonry chimney must have a (1) one-inch air space clearance.
