WARNING
!
CARBON MONOXIDE HAZARD
FURNACE MUST BE VENTED PROPERLY.
FAILURE TO FOLLOW THIS WARNING COULD RESULT
IN CARBON MONOXIDE, FIRE OR SMOKE THAT CAN
CAUSE SERIOUS BODILY INJURY, DEATH OR PROP-
ERTY DAMAGE.
IMPORTANT:
The building owner/maintenance provider must
keep the area around the vent clear from snow.
Proper venting is essential to obtain maximum effi-
ciency from a condensing furnace. Proper installation of
the vent system is necessary to assure drainage of the
condensate and prevent deterioration of the vent sys-
tem.
American Gas Association has certified the design of
condensing Furnaces for a minimum of 0" clearance
from combustible materials with a single wall plastic
vent pipe. See Table 8.
The recommended system is assembled from 2", 2-1/
2", or 3" plastic pipe and fittings (See Table 9, page
18) for material specifications. 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 edi-
tion" 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 sys-
tem is likely to be too large to properly vent the re-
maining attached appliances.
The following steps shall be followed with each appli-
ance remaining connected to the common venting sys-
tem placed in operation, while the other appliances re-
maining connected to the common venting system are
not in operation.

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.
