addition, the chimney must terminate at least 3 feet above any
forced air inlet located within 10 feet. The chimney must extend at
least five feet above the highest connected equipment draft hood
outlet or flue collar.
If the chimney does not meet these termination requirements, but
all other requirements in the checklist can be met, it may be possible
for a mason to extend the chimney. If this will not be practical, see
Fix 1.

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 refined (Fix
4). Remove the cleanout cover, and examine the cleanout for
debris. 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).

HECK INER CONDITION
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
condition.
Remove the lowest existing vent connector, and examine the inside
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.
Venting one appliance inside the liner and another appliance outside
the liner is not acceptable.
Next, use a flashlight and small mirror to sight up the liner. B vent
must be supported so as to not come into direct contact with the
chimney walls or tile liner. If it is not, it can probably be rehung so
as to be acceptable. A thimble or fire stop may be helpful here.
