If this furnace is to be installed in the same space with other gas
appliances, such as a water heater, ensure there is an adequate
supply of combustion and ventilation air for all appliances. Refer
to the latest edition of the National Fuel Gas Code NFPA 54/ANSI
Z223.1 or CAN/CSA B149 Installation Codes or applicable provi-
sions of the local building codes for determining the combustion
air requirements for the appliances.
This furnace must use indoor air for combustion. It cannot be in-
stalled as a direct vent (i.e., sealed combustion) furnace.
Most homes will require outside air be supplied to the furnace
area by means of ventilation grilles or ducts connecting directly
to the outdoors or spaces open to the outdoors such as attics or
crawl spaces.

WARNING
Category I Venting is venting at a non-positive pressure. A furnace
vented as Category I is considered a fan-assisted appliance and
the vent system does not have to be “gas tight.” NOTE: Single stage
gas furnaces with induced draft blowers draw products of com-
bustion through a heat exchanger allowing, in some instances,
common venting with natural draft appliances (i.e. water heat-
ers). All installations must be vented in accordance with National
Fuel Gas Code NFPA 54/ANSI Z223.1 - latest edition. In Canada, the
furnaces must be vented in accordance with the National Stan-
dard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest edi-
tions and amendments.
NOTE: Masonry vent kit (MVK-01 and MVK-02) is to only be used
on interior masonry chimneys or qualifying exterior masonry
chimney applications identified in the MVK kit installation
instructions. To ensure safe and reliable operation, use only the
kit listed for your model.

MINIMUM VENT
Under some conditions, larger vents than those shown above may
be required or allowed. When an existing furnace is removed from
a venting system serving other appliances, the venting system may
be too large to properly vent the remaining attached appliances.
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 ro-
tated 90 degrees with the (0270F01119) chimney transition bot-
tom kit for Category I venting. For upflow models installed verti-
cally or horizontally, a four inch single wall pipe can be used to
extend the induced draft blower outlet 1/2” beyond the furnace
cabinet. THIS PRODUCT IS NOT DESIGNED FOR COUNTERCLOCK-
WISE INDUCED DRAFT BLOWER ROTATION.
Vent the furnace in accordance with the National Fuel Gas Code
NFPA 54/ANSI Z223.1 - latest edition.
Venting - Furnace Installed in Horizontal Position
THIS FURNACE IS NOT DESIGN CERTIFIED TO BE HORIZONTALLY
VENTED THROUGH AN EXTERIOR SIDE WALL.
The following describes an optional venting procedure when the
furnace is installed in the horizontal left discharge position.
To rotate the induced draft blower clockwise, you will need to
purchase one (0270F01119) chimney transition bottom kit.
1. Disconnect electrical power from the furnace.
2. Disconnect the induced draft blower power leads, flue pipe,
and pressure switch tubing.
3. Remove the round cutout from the right side of the wrapper.
4. Remove and save the four screws that fasten the induced
