Upflow or Horizontal units are shipped with the induced
draft blower discharging from the top of the furnace ("Top" is
as viewed for an upflow installation). The induced draft blower
can be rotated 90 degrees for Category I venting. Refer to
the following figure. For horizontal installations, a four inch
single wall pipe can be used to extend the induced draft
blower outlet 1/2" beyond the furnace cabinet. Vent the fur-
nace in accordance with the National Fuel Gas Code NFPA
54/ANSI Z223.1 - latest edition. In Canada, vent the furnace
in accordance with the National Standard of Canada, CAN/

Checklist Summary
This checklist serves as a summary of the items to be
checked before venting an 80% furnace into a masonry chim-
ney. In addition, we recommend that a qualified serviceman
use this checklist to perform a yearly inspection of the fur-
nace venting system.
This checklist is only a summary. For detailed information
on each of the procedures mentioned, see the paragraph
referenced with each item.
This inspection is based upon a draft topical report, "Ma-
sonry Chimney Inspection and Relining", issued by the Gas
Research Institute. While not yet finalized, we believe this
report represents the best information on this subject which
is currently available.
