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).

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.

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) on
the next page.
