This Category ] furnace is fan-assisted. A fan assisted appliance
is an appliance equipped with an integral mechanical means to ei-
ther draw or force products of combustion through the heat ex-
changer.
Category ] furnace definition: A central furnace which operates 8.
with a non-positive vent static pressure and with a flue loss not
less than 17 percent. These furnaces are approved for common-
venting and multi-story venting with other fan-assisted or draft 9.
hood-equipped appliances in accordance with the NFGC or
NSCNGPIC.

Category [ Safe Venting Requirements
Category [ furnace vent installations shall be in accordance with
Parts 10 and 13 of the National Fuel Gas Code (NFGC), ANSI
Z223.1-2002/N FPA 54-2002; and/or Section 7 and Appendix C of
the CSA B149.1-05, National Standard of Canada, Natural Gas
and Propane Installation Code; the local building codes; furnace
and vent manufacturer's instructions.
NOTE: The following instructions comply with the ANSI
Z223.1/NFPA 54 National Fuel Gas Code and CSA B149.1 Natu-
ral Gas and Propane Installation code, based on the input rate on
the furnace rating plate.
If a Category ] vent passes through an attic, any concealed
space or floor, use ONLY Type B or Type L double wall vent
pipe. If vent pipe passes through interior wall, use Type B vent
pipe with ventilated thimble ONLY.
Do NOT vent furnace into any chimney serving an open fire-
place or solid fuel burning appliance.
Use the same diameter Category ] connector or pipe as per-
mitted by:
• the National Fuel Gas Code Code (NFGC) ANSI

or
Vertical outdoor runs of Type-B or ANY single wall vent pipe
below the roof line are NOT permitted.
Slope all horizontal runs up from furnace to the vent terminal a
minimum
of 1/4"
per foot (21 ram/m).
Rigidly support all horizontal portions of the venting system ev-
ery 6' or less using proper clamps and metal straps to prevent
sagging and ensure there is no movement after installation.
Check existing gas vent or chimney to ensure they meet clear-
ances and local codes. See Figure 1
The furnace MUST be connected to a factory built chimney or
vent complying with a recognized standard, or a masonry or
concrete chimney lined with a lining material acceptable to the
authority having jurisdiction. Venting into an unlined ma-
sonry chimney or concrete chimney is prohibited. See the
6. Masonry Chimney Venting section in these instruc-
tions.

Fan-assisted combustion system Category [ furnaces shall
not be vented into single-wall metal vents.
Category [ furnaces must be vented vertically or nearly verti-
cally, unless equipped with a listed mechanical venter.
Vent connectors serving Category I furnaces shall not be con-
nected into any portion of mechanical draft systems operating
under positive pressure.
A 4-to-3 inch reducer is permitted at the flue collar when installing
a 50,000 Btuh gas input furnace, if the installation meets all the fol-
lowing requirements for sizing the vent connectors and vents:
