All installations and services must be performed by qualified service personnel.

5. PROPER CHIMNEY BOTTOM LEVEL:

In cases where the chimney extends to the basement floor, the draft can usually be improved by filling the base of the chimney with sand to within 12 inches of the vent connector pipe after relocating the clean-out door. (See Fig. 5).

6. TIGHT JOINTS:

All joints of the chimney must be tightly sealed. The inside of the chimney should be free of any obstructions, such as loose brick, broken pieces of tile, or corroded metal.

7. TIGHT CLEAN-OUT DOORS AND CONNECTIONS:

All chimney clean-out doors and flue connections must fit tightly so they will seal to avoid air leaks.

8. NO INTERCONNECTED CHIMNEY FLUES:

If chimney flues are divided or there are multiple flues within one chimney, make sure there are no openings in the partition separating the divided or individual flues.

B. FLUE PIPE CLEARANCES, SIZING AND TYPE:

The vent connector pipe must not pass through a combustible wall or partition unless adequate protection is provided at the passageway. An acceptable passageway could be either an approved, ventilated metal thimble which is at least 12 inches larger in diameter than the vent connector pipe, or brick work which is at least 8 inches thick constructed into the wall and surrounding the vent connector pipe. (See Fig. 6).
