D.Blockage within flue; remove.

E.Improper clearance between chimney and com- bustible materials. Generally, a clearance of 2” (50 mm.) is required to all combustible walls and framing members; check local codes.

F.Improper clearance between smoke chamber and adjacent framing members; check local codes.

G.Creosote accumulation; chimney needs thorough cleaning.

H.Structural deterioration of the fireplace; must be repaired before use.

I.Loose or broken bricks or mortar; replace and remortar.

J. Loose or broken clean-out door; repair or replace.

Existing masonry chimneys, especially older ones, may have two or more openings through the chimney walls to the same flue. The openings were used to connect stoves in different rooms to the chimney. The unused openings must be sealed with masonry to the thickness of the chimney wall. Unused openings sealed with pie plates or wallpaper are a hazard. In the event of a chimney fire, flames and smoke may be forced out of

these unused thimbles.

DO NOT CONNECT YOUR STOVE OR INSERT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

Chimney Size

When outfitted with the standard 6” (150 mm) flue col- lar, The Vigilant II Coal Stove is designed to perform well when vented through flues that have these dimen- sions:

Prefabricated

Round Liner, I.D.	6” (150 mm)
Masonry
Square Liner	8” x 8” (nominal)
Rectangular Liner	7” x 11” (nominal)
Round Liner	6” (inside dimensions)

A Vigilant II Coal Stove equipped with the optional 8” (200 mm) flue collar is designed to perform well when vented through flues that have these dimensions:

Prefabricated
Round Liner	8” (inside dimension)
Masonry
Square Liner	8” x 8” (nominal)
Rectangular Liner	8” x 12” (nominal)
Round Liner	8” (inside dimensions)

CHIMNEYS WITH LINERS LARGER THAN 8” X 12” MAY EXPERIENCE RAPID COOLING OF COMBUS- TION GASES AND REDUCTION IN DRAFT, ESPE- CIALLY IF THEY ARE LOCATED OUTSIDE THE HOME.

These large chimneys may need to be insulated or the flues re-lined for good stove performance. Vermont Castings offers chimney lining accessories to help make the connection between stainless steel chimney liners and our stoves and fireplaces.

If you are planning to vent a small stove into a large flue, particularly an exterior masonry flue, you may find it necessary to insulate the chimney, reline the chimney, or operate the stove with the damper open to maintain

high flue temperatures.
