polypropylene venting systems are ULC S636 listed.
NOTE:
When using polypropylene venting systems, all venting
materials used, including the vent terminations must be from the same
manufacturer.
Venting Systems
Direct Vent / 2-Pipe System
In a direct-vent (2-pipe) system, all air for combustion is taken directly
from outdoor atmosphere, and all flue products are discharged to outdoor
atmosphere. Combustion-air and vent pipes must terminate together in
the same atmospheric pressure zone, either through the roof (preferred)
or a sidewall. See
for references to clearances required by
National code authorities.
Ventilated Combustion Air Systems
In a ventilated combustion air option, the vent terminates and discharges
the flue products directly to the outdoors similar to a direct vent system.
See
for references to clearances required by National code
authorities.
All air for combustion is piped directly to the furnace from a space that is
well ventilated with outdoor air (such as an attic or crawl space) and the
space is well isolated from the living space or garage. Combustion air
requirements for this option are the same as the requirements for
providing outside air for combustion for a single pipe vent system. Refer
to the “Air For Combustion and Ventilation” Section.
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:
USA Installations
: Section 9.3 current edition of NFPA 54/ANSI
Z223.1, Air for Combustion and Ventilation and applicable provisions
of the local building codes.
Canadian Installations
: Part 8 of current edition of
CAN/CSA-B149.1. Venting Systems and Air Supply for Appliances
and all authorities having jurisdiction.
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.
pipe. See
for available options.
NOTICE
!
OPTIONAL CONFIGURATION FOR COMBUSTION AIR INLET
PIPE
In applications where there is a risk of excessive moisture entering the
combustion air inlet pipe, a moisture trap may be added to the inlet pipe
to help prevent moisture from entering the furnace from the combustion
air inlet pipe. See
When sizing venting systems, the equivalent length of the optional inlet
pipe moisture trap must be taken into account.
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.
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.
The instructions included with this furnace
DO NOT APPLY
to vent
systems that are located below the furnace.
CAREFULLY FOLLOW
THE INSTRUCTIONS PROVIDED WITH THE EXTERNAL
VENT TRAP KIT FOR LAYING OUT THE VENTING SYSTEM
AND THE DRAIN SYSTEM
when all or part of the venting system is
placed below the furnace.
Proper configuration of the venting and drain system is critical when
placing all or part of the venting system below the level of the furnace.
VENT GASSES COULD BE RELEASED FROM THE
DRAINAGE SYSTEM
if the instructions provided with the External
Vent Trap Kit are not followed.
