GENERAL 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 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 CSA B149.1
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 deficiencies which could cause an
unsafe condition.
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 Z221.1/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 where
when tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any other gas-fired
burning appliance to their previous condition of use.
WARNING
!
CARBON MONOXIDE POISONING HAZARD
FAILURE TO FOLLOW THE INSTALLATION INSTRUCTIONS
FOR THE VENTING SYSTEM BEING PLACED INTO OPERA-
TION COULD RESULT IN CARBON MONOXIDE POISONING
OR DEATH.
Do Not install return air through the side of the furnace
cabinet on horizontal applications.
NOTE: Minimum return air temperature is 55° F.

Installer's Guide
FURNACE EXHAUST MUST BE VENTED TO THE
OUTDOORS. THESE FURNACES ARE INDUCED DRAFT
VENTED AND MUST NOT BE CONNECTED TO ANY
VENT SERVING ANOTHER APPLIANCE. PLEASE NOTE
THAT THESE FURNACES USE POSITIVE-PRESSURE
VENT SYSTEMS.
Proper venting is essential to obtain maximum efficiency
from a condensing Furnace. Proper installation of the vent
system is necessary to assure drainage of the condensate and
prevent deterioration of the vent system.
American Gas Association has certified the design of condens-
ing Furnaces for a minimum of 0" clearance from combustible
materials with a single wall plastic vent pipe.
The recommended system is assembled from 2", 2-1/2", or 3"
plastic pipe and fittings (See Table 10, page 19). Where the
system is routed to the outdoors through an existing masonry
chimney containing flue products from another gas appliance,
or where required by local codes, then 3" venting of Type 29-4C
stainless steel must be used in place of PVC material.
These Furnaces have been classified as CATEGORY IV
Furnaces in accordance with ANSI Z21.47 "latest edition"
standards. Category IV Furnaces operate with positive vent
pressure and with a vent gas temperature less than 140°F
above the dewpoint. These conditions require special venting
systems, which must be gas tight and water tight.
NOTE: When an existing Furnace is removed from a venting
system serving other gas appliances, the venting system is
likely to be too large to properly vent the remaining attached
appliances.
The following steps shall be followed with each appliance
remaining connected to the common venting system placed in
operation, while the other appliances remaining connected to
the common venting system are not in operation.
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and
horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion or other deficiencies which
could cause an unsafe condition.
3. In so far as is practical, close all building doors and
windows and all doors between the space in which the
appliances remaining connected to the common venting
system are located and other spaces of the building. Turn
on clothes dryers and any appliances not connected to the
common venting system. Turn on any exhaust fans, such
as range hoods and bathroom exhausts, so they will
operate at maximum speed. Do not operate a summer
exhaust fan, close fireplace dampers.
4. Follow the lighting instructions. Place the appliance
being inspected in operation. Adjust Comfort Control so
appliance will operate continuously.
5. After it has been determined that each appliance remain-
ing connected to the common venting system properly
vents when tested as outlined above, return door, windows,
exhaust fans, fireplace dampers and any other gas-
burning appliance to their previous conditions of use.
If improper venting is observed during any of the above tests,
the remaining common venting system must be corrected.
Correction could require rerouting or resizing the remaining
vent system.
IMPORTANT: These Furnaces may be installed as Direct
Vent (sealed combustion) or as Nondirect Vent (single pipe).
The Furnaces are shipped DIRECT VENT with sealed
combustion.
