FIGURE 6

There are two separate and different parts to a flue system: the

chimney connector and the chimney itself.

A. Single wall connector or stove pipe. This must be at least

24 gauge mild steel or 26 gauge blue steel. The sections

must be attached to the stove and to each other with

the crimped (male) end pointing toward the stove.

See

Chimney Connector Diagram below. All joints, including

the connection at the stove collar, should be secured

with three sheet metal screws. Make sure to follow

the minimum clearances to combustibles as set out on

page 6 of this manual. Where passage through the wall,

or partition of combustible construction is desired, the

installation shall conform to CAN/CSA-b365 (Canada).

b. Factory-built listed chimney connector (vented). A listed

connector (vented) must be used when installing this unit

in a mobile home. The listed connectors must conform to

each other to ensure a proper fit and seal.

WARNING!! IF INSTALLING THIS MODEL TO A MASONRY CHIMNEY, ALWAYS BE SURE THE CHIMNEY IS IN GOOD

CONDITION AND THAT IT MEETS THE MINIMUM STANDARDS OF THE NATIONAL FIRE PROTECTION ASSOCIATION (NFPA)

STANDARD 211. A FACTORY BUILT CHIMNEY MUST BE 6” (152mm) UL103 HT.

THIS APPLIANCE IS MADE WITH A 6 INCH (152mm) DIAMETER CHIMNEY CONNECTOR AS THE FLUE COLLAR ON THE

UNIT. CHANGING THE DIAMETER OF THE CHIMNEY CAN AFFECT DRAFT AND CAUSE POOR PERFORMANCE. IT IS NOT

RECOMMENDED TO USE OFFSETS OR ELBOWS AT ALTITUDES ABOVE 4000 FEET ABOVE SEA LEVEL OR WHEN THERE

ARE OTHER FACTORS THAT AFFECT FLUE DRAFT.

The flue should be checked to determine that it is not too

large for the stove. NFPA 211 allows the cross-sectional

area of the flue to be no more than 3 times the cross-

sectional area of the flue collar of the stove (28 x 3 =

84 square inches). It is recommended that a chimney

with a larger diameter than 6” (152mm) be relined,

since the oversized flue can cause poor performance

and contribute to the accumulation of creosote. (

See

page 9 for more information about troubleshooting draft

problems).

CAUTION! DO NOT CONNECT THIS UNIT TO A CHIMNEY

FLUE SERVING ANOTHER APPLIANCE.

When connecting the stove through a combustible wall to

a masonry chimney, special methods are needed. There

are several ways to make this connection, including

the construction of a masonry thimble. In Canada, the

installation shall conform to CAN/CSA-b365. Check with

your local building authorities and/or consult the National

Fire Protection Association (NFPA 211).

Refer to Figure

13B on page 13 and Figures 14A & 14B on page 14

MASONRY CHIMNEY

FIGURE 10B

ensure that a masonry chimney meets the minimum standards

of the National Fire Protection Association (NFPA) Standard

211. It must have at least a 5/8" (16mm) fire clay liner or a listed

chimney liner system.

See Figure 11B on page 11. Make sure

there are no cracks, loose mortar or other signs of deterioration

and blockage. It is best to have the chimney inspected by a

professional, and be sure to have the chimney cleaned before

the stove is installed and operated.

MASONRY CHIMNEY (Cont’d)

For optimal performance, masonry chimneys used to vent this

appliance should be lined with a 6" (152mm) stainless steel

liner. Installations into a clay flue without a stainless steel liner

may reduce draw which affects performance, cause the glass

to darken and produce excessive creosote.
