VENTING
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 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 CSA B149 Nat-
ural Gas and Propane Installation Code and these in-
structions. 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. Test for spillage from draft hood equipped appliances
at the draft hood relief opening after 5 minutes of
main burner operation. Use the flame of a match or
candle.
8. 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
Z223.1/NFPA 54 and/or CSA B149.1 Natural Gas
and Propane Installation Code.
9. After it has been determined that each appliance
connected to the venting system properly vents when
tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any other
gas- -fired burning appliance to their previous
conditions of use.
NOTE: Planning for the venting system should be done in
conjunction with planning for the ductwork, drainage, and furnace
accessories, such as air cleaners and humidifiers. Begin assembling
the venting system AFTER the furnace is set in place in the
required orientation.
Venting for this furnace shall follow all Local codes for Category
IV venting systems. This furnace is CSA approved for venting
with PVC/ABS DWV venting systems. This furnace is also CSA
approved for venting with M&G DuraVentR
polypropylene venting systems.

instructions for the polypropylene venting system installation.
NOTE: When using polypropylene venting systems, all venting
materials used, including the vent terminations, must be from the
same manufacturer.

General
If this furnace replaces a furnace that was connected to a vent
system or chimney, the vent or vent connectors of other remaining
appliances may need to be re- -sized. Vent systems or vent
connectors of other appliances must be sized to the minimum size
as determined using appropriate table found in the current edition
of National Fuel Gas Code NFPA 54/ANSI Z- -223.1.
An abandoned masonry chimney may be used as a raceway for
properly insulated and supported
applicable) and vent pipes. Each furnace must have its own set of
combustion- -air and vent pipes and be terminated individually for
Direct Vent (2- -Pipe) system (Fig. 56), for single- -pipe or ventilated
combustion air option (Fig. 57).
A furnace shall not be connected to a chimney flue serving a
separate appliance designed to burn solid fuel.
Other gas appliances with their own venting system may also use
the abandoned chimney as a raceway providing it is permitted by
local code, the current edition of the National Fuel Gas Code, and
the vent or liner manufacturer's installation instructions. Care must
be taken to prevent the exhaust gases from one appliance from
contaminating the combustion air of other gas appliances.
Do not take combustion air from inside the chimney when using
ventilated combustion air or single- -pipe vent option.
These furnaces can be vented as direct- -vent (two- -pipe), ventilated
combustion air or non-direct (single- -pipe) vent system. Each type
of venting system is described below. Common venting between
these furnaces or other appliances is prohibited.
Materials
Combustion air and vent pipe, fittings, primers, and solvents must
conform to American National Standards Institute (ANSI)
standards and American Society for Testing and Materials (ASTM)
standards. For approved materials for use in the U.S.A. (Table 16).
This furnace is also CSA approved for venting with M&G
DuraVentR PolyProR polypropylene venting systems.
NOTE: When using polypropylene venting systems, all venting
materials used, including the vent terminations must be from the
same manufacturer.

WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow the instructions outlined below for each
appliance being placed into operation could result in carbon
monoxide poisoning or death.
For all venting configurations for this appliance and other gas
appliances placed into operation for this structure, provisions
for adequate combustion, ventilation, and dilution air must be
provided in accordance with:
Current edition of Section 9.3 NFPA 54/ANSI Z223.1, Air for
Combustion and Ventilation and applicable provisions of the
local building codes.
NOTICE
RECOMMENDED SUPPORT FOR
VENT TERMINATION
It is recommended that sidewall vent terminations of over 24
inches (0.6 M) in length or rooftop vent terminations of over
36 inches (1 M) in length be supported by EITHER the
factory accessory vent termination kit or field- -supplied
brackets or supports attached to the structure. A factory
accessory vent termination kit may be used for direct vent
terminations. Termination kits are available for 2- -in. or 3- -in.
