HECKLIST UMMARY
This checklist serves as a summary of the items to be checked
before venting an 80+ furnace into a masonry chimney. In addi-
tion, we recommend that a qualified serviceman use this check-
list to perform a yearly inspection of the furnace venting sys-
tem.
This checklist is only a summary. For detailed information on
each of the procedures mentioned, see the paragraph refer-
enced with each item.
This inspection is based upon a draft topical report, "Masonry
Chimney Inspection and Relining", issued by the Gas Research
Institute. While not yet finalized, we believe this report repre-
sents the best information on this subject which is currently
available.

ROPER 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 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 equip-
ment 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.
