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 Natural Gas and Propane Installation Code 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. 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
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

manufacturer's installation 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 combustion-air (when 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 (see
Fig. 56), for single-pipe or ventilated combustion air option (see
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.
