GENERAL VENTING INSTRUCTIONS

WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each
appliance connected to the venting system being
placed into operation could result in carbon monoxide
poisoning or death.
The following steps shall be followed for each appliance
connected to the venting system being placed into
operation, while all other appliances connected to the
venting system are not in operation:
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and
horizontal pitch, as required in the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 or the CAN/CGA B149
Installation Codes and these instructions. Determine
that there is no blockage or restriction, leakage,
corrosion and other deficiencies which could cause an
unsafe condition.
3. As far as practical, close all building doors and
windows and all doors between the space in which the
appliance(s) connected to the venting system are
located and other spaces of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not
connected to the venting system. Turn on any exhaust
fans, such as range hoods and bathroom exhausts, so
they are operating at maximum speed. Do not operate
a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance
being inspected into operation. Adjust the thermostat
so appliance is operating continuously.
7. If improper venting is observed during any of the above
tests, the venting system must be corrected in
accordance with the National Fuel Gas Code,
ANSI Z221.1/NFPA 54 and/or CAN/CGA B149
Installation Codes.
8. After it has been determined that each appliance
connected to the venting system properly vents where
tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any other gas-fired
burning appliance to their previous conditions of use.

VENT PIPING
These furnaces have been classified as Fan-Assisted
Combustion System, Category I furnaces under the "lat-
est edition" provisions of ANSI Z21.47 and CAN/CGA 2.3
standards. Category I furnaces operate with a non-positive
vent static pressure and with a flue loss of not less than 17
percent.
NOTE:
If desired, a side wall termination can be accomplished
through the use of an "add-on" draft inducer. The inducer
must be installed according to the inducer manufacturer's
instructions. Set the barometric pressure relief to achieve
-0.02 inch water column.
NOTE: When the downflow furnace is vented through the
left side of the furnace cabinet using the provided cutout,
Type B vent piping must be used.
The furnace shall be connected to a factory built chim-
ney or vent complying with a recognized standard, or a
masonry or concrete chimney lined with a lining material
acceptable to the authority having jurisdiction.
WARNING
!
Furnace venting into an unlined masonry chimney or con-
crete chimney is prohibited. Failure to follow this warning
could result in property damage, personal injury, or death.
VENTING INTO A MASONRY CHIMNEY
If the chimney is oversized, the liner is inadequate, or
flue-gas condensation is a problem in your area, consider
using the chimney as a pathway or chase for type "B" vent
or flexible vent liner. If flexible liner material is used, size
the vent using the "B" vent tables, then reduce the maxi-
mum capacity by 20% (multiply 0.80 times the maximum
capacity). Masonry Chimney Kit BAYVENT800B may be
used with these furnaces (Upflow model furnaces only)
to allow venting into a masonry chimney. Refer to the BAY-
VENT800B Installer's Guide for application requirements.
Internal Masonry Chimneys
Venting of fan assisted appliances into a lined, internal ma-
sonry chimney is allowed only if it is common vented with
at least one natural draft appliance; OR, if the chimney
is lined with type "B", double wall vent or suitable flexible
liner material (See Table 7).
WARNING
!
The chimney liner must be thoroughly inspected to insure
no cracks or other potential areas for flue gas leaks are
present in the liner. Liner leaks will result in early deterio-
ration of the chimney.
Failure to follow this warning could result in carbon mon-
oxide poisoning or death.
