Lennox Hearth T300HT Installation, Baffle Plates, Installing Leg Levelers, Types Of Chimneys

INSTALLATION

BAFFLE PLATES

This appliance has two heavy steel baffle plates that are installed in the upper firebox (over the steel secondary air supply tubes). During shipment and installation, the baffle plates might slide around, and may need to be repositioned (lined up to each other) and pushed to the back wall in order for the stove to operate properly. When in the proper position, the rear edges of the baffle plates should be flush to the back wall of the firebox. See Removing Baffle Plates for Cleaning on page 17 for additional information on installing baffle plates.

INSTALLING LEG LEVELERS

The four leg levelers (included in accessory package), screw into the tapped (threaded) holes on the bottom of the four legs. Level the stove by adjusting the screws in or out.

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 diameter, which is approximately 28 square inches minimum. The maximum 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 diameter stack, or approxi- mately 85 square inches 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 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 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 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 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 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 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.
