Check 1 - Proper chimney termination.
A masonry chimney used as a vent for gas fired equip-
ment must extend at least three feet above the highest
point where it passes through the roof. It must extend at
least two feet higher than any portion of a building within
a horizontal distance of 10 feet. In 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 require-
ments, 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, page 12.

Check 2 - Any solid or liquid fuel appliances
vented into this chimney channel
Solid fuel appliances include fireplaces, wood stoves,
coal furnaces, and incinerators.
Liquid fuel appliances include oil furnaces, oil-fired boil-
ers and oil-fired water heaters.
Appliances which burn propane (sometimes referred to
as LP (liquefied petroleum)) gas are considered gas-fired
appliances.
Check 3 - Chimney Crown Condition.
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 pints. (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 neces-
sary to follow both Fix 3 and Fix 4.
