Damage from condensate usually shows up first in the crown. If any
of the following trouble signs are present, the condition of the
crown is not satisfactory:
a) Crown leaning
b) Bricks missing
c) Mortar missing
d) Tile liner cracked
e) No tile liner
f ) Salt staining at mortar joints. (White stains, and mortar
becomes sandy and/or erodes.)
For problems a, b, or c, see Fix 3. If problems d, e, or f are present,
see Fix 4. IMPORTANT: It may be necessary to follow both Fix 3 and
Fix 4.

A cleanout (dropleg) must be present such that the upper edge of
the cleanout cover is at least 12 inches below the lower edge of the
lowest chimney inlet opening.
A chimney without a cleanout could become partially blocked by
debris. If no cleanout is present, the chimney must be relined (Fix
4). Remove the cleanout cover, and examine the cleanout for de-
bris. If significant amounts of any of the following are found:
•
Fuel oil residue
•
Bricks
•
Mortar or sand
•
Pieces of the tile liner
•
Rusted pieces of the metallic liner - reline the chimney
(Fix 4).

If a metal liner is present, it must be checked. It cannot be assumed
that all existing metal liners are correctly installed and in good con-
dition.
Remove the lowest existing vent connector, and examine the in-
side of the elbow or tee at the base of the liner. A small amount of
soot may be considered acceptable, provided the installer vacuums
it away. If rusted pieces of the liner have collected here, the metal
liner must be removed and replaced (Fix 4).
Next, gently tap the inside of the liner with a Phillips screwdriver. If
the screwdriver perforates the liner, or if the tapping does not sound
like metal hitting metal, the liner must be removed and replaced
(Fix 4).
Remember that all appliances must be vented inside the liner. Vent-
ing one appliance inside the liner and another appliance outside
the liner is not acceptable.
If the chimney does not meet these termination requirements, but
all other requirements in the checklist can be met, it may be pos-
sible for a mason to extend the chimney. If this will not be practical,
see Fix 1.
