INSTALLATION

TYPES OF CHIMNEYS

The chimney is a vital part of your stove installation. A properly built masonry chimney or a properly installed factory built chimney will assure a consistent draft under a variety of weather conditions (a smoking stove is usu- ally caused by a chimney problem). The stove flue size is 6 inches (I52 mm) diameter, which is approximately 28 square inches (711 square mm) minimum. The maxi- mum flue size should be no more than (3)-three times the cross sectional area of the size of the stove flue collar. In this case, that would be no larger than a 10-inch (254

mm)diameter stack, or approximately 85 square inches 216 square cm) maximum.

All chimneys must be installed as specified by local building codes and according to the chimney manufac- turer instructions (in the case of a factory built chimney). See the chimney manufacturer instructions for exact specifications. Factory built chimneys must comply with UL 103HT or ULC S629.

ACCEPTABLE CONNECTOR PIPE FOR INSTALLA- TIONS

For Standard Residential Clearances: Six 6 inch (152

mm)minimum, single wall, 25 gage minimum thickness, stove pipe is acceptable. 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. Addi- tional sections of single wall pipe should be fastened to- gether with at least three (3) sheet metal screws each section. When connecting to the factory built ceiling sup- port 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 sec- tional area of the size of the 6 inches / 152 mm diameter 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 con- forming to CAN / ULC – S629, Standard for 650°C Fac- tory-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 manufac- turer's instructions.

Vapor Barrier at Chimney Penetration: Install all

venting components per the Vent Manufacturers installa- tion instructions. Ensure that there is an effective 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 fol- lowing components:

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

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 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 chim- ney 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 bro- ken or missing pieces. Some non-code masonry chim- neys may be brought up to code by being relined. (Con- sult your dealer or qualified chimney sweep).

Factory 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 re- place 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 chimneys, this must be a

(2)-two inch (51 mm) air space clearance, which must not be filled with insulation or any other material. An exterior masonry chimney must have a (1) one-inch (25.4 mm) air space clearance.
