CHECK 1 - PROPER CHIMNEY TERMINATION.
A masonry chimney used as a vent for gas fired equipment 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 addi-
tion, 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.
