1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and horizontal pitch, as required by the National Fuel Gas Code, ANSI
Z223.1 or the Natural Gas and Propane Installation Code, CSAB149.1-05 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 shall operate at maximum speed. Do not operate a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance being inspected in operation.Adjust thermostat so appliance shall
operatecontinuously.
7. Test for spillage from draft hood 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
withthe National Fuel GasCodeANSI Z223.1/NFPA54 and/or National Gas and Propane Installation Code CSAB149.1-05.
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 burning appliance to their
previous conditions of use.
If resizing is required on any portion of the venting system, use the appropriate table inAppendix G in the latest edition of the
National Fuel Gas CodeANSI Z223.1 and/or CSAB149.1-05 Installation Codes.

V ENT /F LUE P IPE & C OMBUSTION A IR P IPE
A condensing gas furnace achieves its high level of efficiency by extracting almost all of the heat from the products of combustion
and cooling them to the point where condensation takes place. Because of the relatively low flue gas temperature and water
condensation requirements, PVC pipe is used as venting material.
In addition to PVC andABS pipe and fittings, Innoflue®by Centrotherm Eco Systems and PolyPro®by M&G Duravent are also
approved vent and combustion air materials for installations in the U.S.A. and Canada. Manufacturers Installation instruc-
tions for these products must be followed. These products have specific instructions for installing, joining and terminating.
Do not mix materials or components of one manufacturer with materials or components of another manufacturer.
All furnaces are built with 2" vent / intake pipe and connectors. For furnaces requiring installation of 3" pipe, the transition
from 2" to 3" should be done as close to the furnace as practically possible.
Thisfurnace mustnotbe connectedtoTypeB,BW,orLventorvent connector,andmustnotbeventedintoany portionofa factory
built or masonry chimney except when used as a pathway for PVC as described later in this section. Never common vent this
appliance with another appliance or use a vent which is used by a solid fuel appliance. Do not use commercially available “no hub
connectors”other thanthoseshipped withthisproduct.
It is the responsibility of the installer to follow the manufacturers’ recommendations and to verify that all vent/flue piping and
connectorsarecompatiblewithfurnaceflueproducts. Additionally,itistheresponsibilityoftheinstallertoensurethatallpipingand
connections possess adequate structural integrity and support to prevent flue pipe separation, shifting, or sagging during furnace
operation.

MATERIALS AND JOINING METHODS
Two-three-inch nominal diameter PVC Schedule 40 pipemeet-
ing ASTM D1785, PVC primer meeting ASTM F656, and PVC
solvent cement meeting ASTM D2564 specifications must be
used. Fittings must be DWV type fittings meetingASTM D2665
andASTM D3311. Carefully follow the manufacturer’s instruc-
tions for cutting, cleaning, and solvent cementing of PVC.
The use of Schedule 40 PVC cellular core DWV meetingASTM
F891-1 orABS cellular core (Foam Core) plastic pipe is also acceptable as a flue/vent and intake pipe material. PVC primer
meetingASTM F656 and PVC solvent cement meetingASTM D2564 specifications must be used. Fittings must be DWV type
fittings meeting ASTM D2665 and ASTM D3311. Carefully follow the manufactures instructions for cutting, cleaning and
solvent cementing of PVC.
For Canadian installations; all PVC pipe, fittings and joining materials must be UL S636 listed.
As an alternative to PVC pipe, primer, solvent cement, and fittings, ABS materials which are in compliance with the following
specifications may be used. Two-or-three-inchABS Schedule 40 pipe must meetASTM D1527 and, if used in Canada, must be CSA

STANDARD FURNACE CONNECTIONS
It is the responsibility of the installer to ensure that the piping connections to the
furnacearesecure,airtight, andadequatelysupported.
VENT/FLUEPIPE
The vent pipe outlet is sized to accept 2” pipe. Secure vent/flue pipe directly
into the furnace fitting with the appropriate glue. Alternately, a small section
of 2" pipe may be glued in the furnace socket and a rubber coupling installed to
allow removal for future service. Combustion Air and Vent piping should be
routed in a manner to avoid contact with refrigerant lines, metering devices,
condensate drain lines, etc. If necessary, clearances may be increased by
creating an offset using two 45 degree elbows. This joint can be rotated on the
fitting to establish maximum clearance between refrigerant lines, metering
devices, and condensate drain lines, etc. This joint is the equivalent of one 90
deg. elbow when considering elbow count. (See Figure 9A)
NOTE: For non-direct vent installations, a minimum of one 90° elbow should be
installed on the combustion air intake coupling to guard against inadvertent
blockage.
COMBUSTION AIR PIPE
DIRECT VENT INSTALLATIONS
Onupflow units securethe combustionair intake pipe to theair intakecoupling by using a
take apart rubber coupling supplied with the furnace or a plastic coupling. Also, the

sation is a concern. If the RF000142 is used on the combustion air inlet, it must be installed with the arrow pointing up. It
should be noted, the combustion air will actually be moving in a direction opposite of the arrow on the RF000142 coupling. It
must have a field supplied, trapped drain tube free-draining to proper condensate disposal location. Aloop in the drain tube
can serve as a trap. The unused RF000142 drain fitting should be capped. (See Figure 9B)

ALTERNATE VENT/FLUE LOCATION
The alternate vent/flue location is the large hole directly in line
withtheinduceddraftbloweroutlet. Tousethealternatevent/flue
locationreferto the following steps and the “Alternate Vent/Flue
Location” figure. To use an alternate vent location on a
counterflow / horizontal model, a special kit is required.
NOTE: In the horizontal left installation position, a means of
condensate collection must be provided to keep vent pipe con-
densate from entering the draft inducer housing. If the vent
drain elbow is eliminated from the installation, an RF000142
kit must be used.
1. Remove the four screws from the vent pipe flange on top
the furnace.
2. Remove the internal elbow and vent pipe
3. Cut 2 1/2" from the flange .
4. Remove plastic plug in line with the inducer outlet
5. Installcutend of the flanged section and connecttoinducer

6. Install screws removed in step 1 securing flange to cabinet.
ALTERNATE COMBUSTION AIR PROVISION
(Upflow / Horizontal models only)
When using the alternate venting location, either in a horizon-
tal left side down installation or a vertical installation using down – venting, an alternate combustion air opening can be
used.Alocating dimple is located on the right side of the furnace cabinet. The locating dimple is 1 7/8" measured from the
front edge of the cabinet in line with the knock out. To use the alternate combustion air location:
1. Remove screws and combustion air flange from cabinet.
2. Insert cabinet plug in unused combustion air hole.
3. Drill a pilot hole at the cabinet dimple (size dictated by knockout tool used).
4. Use a knockout tool to create a 3" diameter hole
5. Install combustion air flange and secure with screws removed in step one.

NON-DIRECT VENT (SINGLE PIPE)PIPING
Non-direct vent installations require only a vent/flue pipe. The
vent pipe can be run horizontally with an exit through the side of
the building or run vertically with an exit through the roof of the
building. The vent can also be run through an existing unused
chimney;however, it must extend a minimumof12 inches above the top ofthe chimney. Thespace between the vent pipe andthe
chimneymustbeclosed with a weather-tight, corrosion-resistant flashing.
Althoughnon-directventinstallationsdonotrequireacombustionairintakepipe,aminimumofone90°elbowshouldbeattachedto
thefurnace’s combustionairintake if:anupright installation uses the standard intake location,ora horizontal installation uses the
alternateair intake location. This elbow will guardagainst inadvertent blockage of the airintake.
VENT/FLUE PIPE LENGTHS AND DIAMETERS
NOTE: For installations at or above 7,000 feet altitude, use 3” venting. If either a 90 degree or 45 degree elbow is used for
termination, it must be pointed downward.

1) Maximum allowable limits listed on individual lengths for
inlet and flue and NOT a combination.
2) Minimum requirement for each vent pipe is five (5) feet
in length and one elbow/tee.
3) Tee used in the vent/flue termination must be included
when determining the number of elbows in the piping sys-
tem
4) 2 1/2” or 3” diameter pipe can be used in place of 2”
diameter pipe.
5) Increased Clearance Configurations using (2) 45 deg.
Long Sweep elbows should be considered equivalent to one
90 deg. elbow.
6) One 90° elbow should be secured to the combustion air
intake connection.
NOTE: For installations at or above 7,000 feet altitude, use
3” venting.
VENT/FLUE PIPE TERMINATIONS
NOTE: If either a 90 degree or 45 degree elbow is used for
termination, it must be pointed downward.
Thevent/flue pipemayterminate vertically,as througharoof, orhorizontally,as throughanoutside wall.

DIRECT VENT (DUAL PIPE) PIPING
Direct vent installations require both a combustion air intake and a vent/
fluepipe. Thepipesmayberunhorizontallyandexitthroughthesideofthe
building or run vertically and exit through the roof of the building. The
pipesmayberun throughanexisting unusedchimney;however,they must
extend a minimum of 12 inches above the top of the chimney. The space
between the pipes and the chimney must be closed with a weather tight,
corrosion resistant flashing. Both the combustion air intake and a vent/
flue pipe terminations must be in the same atmospheric pressure zone.
Refer to Vent/Flue and Combustion Air Pipe - Termination Locations or
Concentric Vent Termination for specific details on termination construc-
tion. Fordetailsconcerningconnectionof pipestothefurnace,refertothe
Vent/Flue Pipe and Combustion Pipe - Standard Furnace Connections or
AlternateFurnaceConnections.
VENT/FLUE & COMBUSTION AIR PIPE LENGTHS & DIAMETERS
Refer to the following table for applicable length, elbows, and pipe di-
ameter for construction of the vent/flue and combustion air intake
pipe systems of a direct vent (dual pipe) installation. The number of
elbows tabulated represents the number of elbows and/or tees in each
(Vent/Flue & CombustionAir Intake) pipe. Elbows and/or tees used in
the terminations must be included when determining the number of
elbows in the piping systems.

VENT/FLUE AND COMBUSTION AIR PIPE TERMINATIONS
Thevent/flue and combustion airpipesmayterminatevertically, as througharoof,or horizontally, asthroughanoutsidewall.
Vertical pipe terminations should be as shown in the following figure. Refer to Vent/Flue Pipe and Combustion Pipe - Termination
Locations for details concerning location restrictions. The penetrations through the roof must be sealed tight with proper flashing
such as is used with a plastic plumbing vent.
VENT & COMBUSTION AIR INTAKE MEASUREMENTS FOR STANDARD HORIZONTAL TERMINATIONS (DUAL PIPE)
Center to center = 10” min / 24” max.
Vertical separation: 0” - 24”
Vent termination from wall = 8” min / 12” max.

SIDE WALL VENT KIT
This kit is to be used with 2” or 3” direct vent systems. The vent kit
must terminate outside the structure and may be installed with the
intakeandexhaustpipes located side-by-side or with one pipe above
the other. These kits are NOT intended for use with single pipe (indi-
rectvent) installations.
Refer to the directions furnished with the Side Wall Vent Kit (p/n
0170K00000S or 0170K00001S)for installation specifications.
C ONDENSATE D RAIN L INES & D RAIN T RAP
A condensing gas furnace achieves its high level of efficiency by ex-
tracting heat from the products of combustion to the point where
condensation takes place. The condensate must be collected in the furnace drain trap and routed to an appropriate drain
location in compliance with local and national codes.
Followthebulletslistedbelowwheninstallingthedrainsystem. Refertothefollowingsectionsforspecificdetailsconcerningfurnace
drain trap installation and drain hose hook ups.
• Thedraintrapsuppliedwiththefurnacemustbeused.
• The drain trap must be primed at time of installation.
• Thedrain linebetweenfurnace anddrainlocation must meet local and nation codes.
• Thedrain linebetween furnaceanddrain locationmust maintain a1/4 inchperfoot downwardslope towardthedrain.
• Donottrap the drain line inanyotherlocationthanatthe drain trap supplied withthefurnace.
• If the drain line is routed through an area which may see temperatures near or below freezing, precautions must be
takento prevent condensatefromfreezing within thedrainline.
• If an air conditioning coil is installed with the furnace, a common drain may be used. An open tee must be installed in
the drain line, near the cooling coil, to relieve positive air pressure from the coil’s plenum. This is necessary to prohibit
anyinterference withthefunction ofthefurnace’sdraintrap.
NOTE: In vertical installations, air conditioning coil condensate may drain into the furnace trap as long as there is a trap
between the coil and the furnace trap and the drain pipe is not terminating below the water level of the furnace trap.
GENERAL DRAIN INFORMATION
All furnace models come with a factory installed drain trap. For vertical installations, the trap will remain in the factory
position except for a counterflow when the installer desires the drain to exit the right side. All furnace models installed
horizontally require the trap to be relocated. Many drain hoses have a built–in grommet which will provide a cabinet seal when
installed. See instructions below for your model and installation position. NOTE: Both sides of the drain trap must be
primed prior to initial furnace start up
FIELD SUPPLIED DRAIN
Drain the furnace and air conditioning coil if applicable, in compliance with code requirements. In horizontal or counterflow
installations, a field installed rubber coupling will allow the drain trap to be removed for cleaning. The drain trap must be

primed before initial furnace start up. When an air conditioning coil
drain is connected to the field supplied furnace drain, it must be
vented, with an open tee installed at a height no higher than the
bottom of the furnace collector box to prevent air conditioning con-
densate from backing up into the furnace if the common drain was
blocked.
UPFLOW MODEL INSTALLED VERTICALLY
The trap and factory installed hoses remain as shipped. The furnace
drain may exit either the right or left side of the furnace cabinet.
Both sides of the cabinet have two .875” diameter holes which can be
used interchangeably for drain and low voltage wiring purposes. If a
higher drain exit is needed, a .875” diameter hole may be added in
the area shown in Figure 22. Any unused cabinet opening must be
sealed. Do not allow drain hose to sag or trap water.
