VENTING AND COMBUSTION
AIR REQUIREMENTS
General
Provisions must be made in the installation of
this furnace to provide an adequate supply of air
for combustion. Detailed instructions for deter-
mining the adequacy of an installation can be
found in the current revision of the National Fuel
Gas Code (ANSI Z223.1 / NFPA54) or in appli-
cable local building codes. Consult local codes
for special requirements. For Canadian in-
stallations consult Canadian Installations Codes
and (CAN/CGA B149.1 or .2).
If the furnace is operated with inadequate air for
combustion one of the flame roll-out switches
located in the burner compartment or the vent
switch will open, turning off the gas supply to the
burners. These safety devices are manually
reset switches. DO NOT install jumper wires
across these switches to defeat their function.
DO NOT reset a switch without identifying and
correcting the fault condition. If a switch must be
replaced, use only the correct part specified in
the Replacement Parts List.
Air openings in the furnace door, warm air
registers, and return air grilles must not be
restricted.
When determining combustion air space,
the full rate input of this two-stage furnace
must be used.
Combustion Air Quality
To maximize heat exchanger life, the combus-
tion air must be free of chemicals which form
corrosive acidic compounds in the combustion
gases. The recommended source of combus-
tion air is to use the outdoor air supply. How-
ever, the use of indoor air in most applications
is acceptable except as follows:
1. If the furnace is installed in a confined space it
is recommended that the necessary combus-
tion air come from the outdoors by way of attic,
crawl space, air duct, or direct opening.
2. If outdoor combustion air is used, there must be
no exposure to the installations or substances
listed in Item 3 below.
3. The following types of installation may require
Outdoor Air for combustion, due to chemical
exposures:
• Commercial buildings
• Buildings with indoor pools
• Furnaces installed in laundry rooms
• Furnaces installed in hobby or craft rooms
• Furnaces installed near chemical storage
areas
Exposure to the following substances in the
combustion air supply may also require Out-
door Air for combustion:
• Permanent wave solutions
• Chlorinated waxes and cleaners
• Chlorine based swimming pool chemicals
• Water softening chemicals
• De-icing salts or chemicals
• Carbon tetrachloride
• Halogen type refrigerants
• Cleaning solvents (such as perchloroethyl-
ene)
• Printing inks, paint removers, varnishes,
etc.
• Hydrochloric acid
• Cements and glues
• Antistatic fabric softeners for clothes dryers
• Masonry acid washing materials
!
CAUTION:
Combustion air must not be drawn from
a corrosive atmosphere.
!
WARNING:
Furnace installation using methods other
than those described in the following
sections must comply with the National
Fuel Gas Code and all applicable local
codes to provide sufficient combustion
air for the furnace.
Installation In An Unconfined Space
An unconfined space is an area including all
rooms not separated by doors with a volume
greater than 50 cubic feet per 1,000 Btuh of the
combined input rates of all appliances which
draw combustion air from that space. For ex-
ample, a space including a water heater rated
at 45,000 Btuh input and a furnace rated at
75,000 Btuh requires a volume of 6,000 cubic
feet [50 x (45 + 75) = 6,000] to be considered

13
unconfined. If the space has an 8 foot ceiling, the
floor area of the space must be 750 square feet
(6,000 / 8 = 750). In general, a furnace installed
in an unconfined space will not require outside
air for combustion. However, in “tight” buildings
(with weather stripping and caulk to reduce
infiltration), it may be necessary to provide
outside air to ensure adequate combustion and
venting, even though the furnace is located in
an unconfined space.
Installation In A Confined Space
A confined space is an area with volume less
than 50 cubic feet per 1,000 Btuh of the com-
bined input rates of all appliances drawing
combustion air from that space. Furnace clos-
ets, small equipment rooms and garages are
confined spaces. Furnaces installed in a con-
fined space which supply heated air to areas
outside the space must draw return air from
outside the space and must have the return air
ducts tightly sealed to the furnace. A confined
space must have two openings into the
space for combustion air. One opening
must be within 12 inches of the ceiling, and
the other must be within 12 inches of the
floor. The required sizing of these openings is
determined by whether inside or outside air is
used to support combustion, the method by
which the air is brought to the space, and by the
total input rate of all appliances in the space.
Horizontal Furnace Installation
The *TA series furnaces can be installed hori-
zontally in an attic, basement, crawl space or
alcove. It can be suspended from a ceiling in a
basement or utility room in either a right to left
airflow or left to right airflow. (See Figures 7 and
8.)
If the furnace is to be suspended from the
ceiling, it will be necessary to use steel straps
around each end of the furnace. These straps
should be attached to the furnace with sheet
metal screws and to the rafters with bolts. The
furnace could also be suspended by an angle
iron frame bolted to the rafters. (See Figure 7.)
Access for positioning and servicing must be
considered when locating the unit. Refer to
Table 3, Minimum Clearances to Combustible
Material, for clearance specifications.
Keep all insulating materials away from the
louvered door. Insulating materials may be
combustible.
The *TA series furnace may be installed directly
on combustible wood flooring or supports, if
type "B-1" vent pipe is used (See Figure 8). It
is recommended for further reduction of fire
hazard that cement board or sheet metal be
placed between the furnace and the combus-
tible floor and extend 12 inches beyond the front
of the louvered door.
!
WARNING:
Furnaces installed with combustion air
drawn from a heated space which in-
cludes exhaust fans, fireplaces, or other
devices that may produce a negative
pressure should be considered con-
fined space installations.

See the venting section for venting guidelines
and specifications.
Air From Inside (See Figure 9)
If combustion air is taken from the heated
space, the two openings must
each have a free
area of at least one square inch per 1,000 Btuh
of total input of all appliances in the confined
space, but not less than 100 square inches
of free area. For example, if the combined input
rate of all appliances is less than or equal to
100,000 Btuh, each opening must have a free
area of at least 100 square inches. If the com-
bined input rate of all appliances is 120,000
Btuh, each opening must have a free area of at
least 120 square inches.
Outdoor Air Using Vertical Ducts
(See Figure 10)
If combustion air is taken from outdoors through
vertical ducts, the openings and ducts must
have a minimum free area of one square inch
per 4,000 Btuh of total appliance input. In instal-
lations drawing combustion air from a ventilated
attic, both air ducts must extend above the attic
insulation.
If the unit is installed in an area with an exhaust
fan, provide sufficient ventilation to prevent
negative pressures from occurring in the room.
The combustion air openings must not be re-
stricted in any manner.
!
CAUTION:
Do not supply combustion air from an
attic space that is equipped with power
ventilation or any other device that may
produce a negative pressure.

In Canada, venting shall conform to the require-
ments of the current (CAN/CGA B149.1 or .2)
installation codes. Consult local codes for
special requirements.
For Category I furnace installations, the fur-
nace shall be connected to a factory built
chimney or vent complying with a recognized
standard, or a masonry or concrete chimney
lined with a lining material acceptance to the
authority having jurisdiction. Venting into an
unlined masonry chimney or concrete chim-
ney is prohibited.
This furnace must never be vented to a chim-
ney flue servicing a fireplace or other appliance
designed to burn solid fuel. If the furnace vent
is to be connected to a chimney serving a
fireplace, the fireplace must be sealed off from
the chimney. Single wall metal vents shall not be
used for Category I venting, Category I fur-
naces must be vented vertically or near verti-
cally.
The furnace vent, if metal, may be insulated if
local codes allow. Any part of the vent system,
metal vent only, not exposed to weather, but
which are exposed to ambient temperatures
below 35° F must be insulated to prevent con-
densation. All vent insulation shall be foil backed
fiberglass of one inch minimum thickness.

Three sheet metal fasteners (field supplied)
should be used to secure the vent pipe to the
furnace flue. These fasteners should be evenly
spaced around the flue diameter, if possible.
Category I - Common Venting
When an existing furnace is removed from a
venting system serving other appliances, the
venting system is likely to be too large to
properly vent the remaining appliances. An
improperly sized venting system can result in
the formation of condensate, leakage, spillage,
etc.
The steps outlined in the warning below shall be
followed with each individual appliance con-
nected to the vent system placed in operation,
while all other appliances connected to the vent
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 Codes
and these instructions. Deter-
mine 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 Instal-
lation Codes
.
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.

17
The venting system should be designed to
have the minimum number of elbows or turns.
All horizontal runs shall be sloped upwards from
the furnace at 1/4 inch per running foot of vent.
Supports for the vent pipe must be installed a
minimum of every five feet along the vent run to
ensure no displacement after installation.
Under no circumstances shall any portion of
the vent system extend into or pass through
any return air duct, supply air duct, or plenum.
If the furnace is operated with blocked or
restricted venting, the blocked vent switch
located in the vent plate will open, turning off the
gas supply to the burners. The blocked vent
switch is a manually reset device. DO NOT
install a jumper wire across this switch to defeat
its function. DO NOT reset the switch without
identifying and correcting the fault condition
which caused the switch to trip. If this switch
must be replaced, use only the part specified in
the Replacement Parts List.
!WARNING:
Upon completion of the furnace installa-
tion, carefully inspect the entire flue sys-
tem both inside and outside the furnace
to assure it is properly sealed. Leaks in
the flue system can result in serious
personal injury or death due to exposure
of flue products, including carbon mon-
oxide.
Category III: Horizontal Venting
NOTE: The reduced NOx models (eighth
character N) are not approved as a Cat-
egory III (Category III) furnace for use with
horizontal venting.
The furnaces are approved for use with 3"
single wall AL29-4C stainless steel vent
pipe in horizontal vent applications. This
pipe is available from the following manufac-
turers:
Z-FLEX Inc. - vent brand name (Z-VENT)
Heat-fab Inc. - vent brand name (Saf-T Vent)
Flex-L International - vent brand name (Star-
34 Vent)
This vent pipe must be used for the entire length
of the vent run. The installation must be in
accordance with all instructions supplied by the
vent manufacturer for use on Category III
appliances. When venting horizontal, this is
defined as a Category III furnace, the vent
pressure is positive, and the venting system
must be sealed in both horizontal and vertical
runs.
For horizontal venting installations in both the
United States and Canada the transition as-
sembly must be modified by adding a bleed tube
to the pressure switch tube and bypassing the
vent switch. All model furnaces will require Vent
Kit #903196 for horizontal venting.
NOTE: No bleed tube is required for the *RA
045(C,N)-08 model.
Horizontal Venting For Upflow Models:
1. Remove the rubber tubing from the pressure
switch sensor tube and the collector pan sen-
sortube. Cut 1/2inch fromone end of the rubber
sensor tube, fold in half and cut along the bend
line. Discard the 1/2 inch long piece of tubing.
Select the correct bleed tube using the table
supplied with vent kit #903196 and place the
other two pieces of tubing on both ends of the
bleed tube. Do not cover the hole in the bleed
tube. Place the assembly back on the pressure
switch sensor tube and the collector pan sen-
sor tube. (See Figure 14.)
2. Remove the nut and restrictor plate from the
vent collar assembly and discard the restrictor
plate. Select the appropriate dilution cover plate
asnotedwith ventkit #903196. Fittheclearance
hole in the cover plate over the weld stud. The
cover plate must cover the hole(s) on the vent
collar assembly. Tighten the nut securely while
holding the cover plate in position. (See Figure
15.)
3. Bypass the vent switch by removing both wires
from the vent switch and attaching them to the
wire nut. (See Figure 16.)

The components of the horizontal vent system
must not be penetrated with screws, rivets, or
other devices, either when joining pipes and
fittings or using support straps. All joints must
be sealed with high temperature silicone before
locking bands are installed. If the lengths of pipe
must be cut, the joint must still be sealed with
silicone and the locking band used. When
installing the condensate tube be sure to form
a trap by means of a 3" loop filled with water.
(See Figure 20.)
Keep the number of pipe fittings to a minimum.
Maintain a minimum of 6 inches of air space
between the vent and combustibles at all times,
this includes inside and outside the building.
NOTE: The direction of the male-female joints
from the drain tee to the termination tee is
opposite to standard gas appliance venting.
The male end of the pipes point towards the
furnace.
Horizontal Venting: *TK Models:
1. By-pass the vent switch, located on blower
compartment door, by removing both wires
from the switch. Remove wire terminals, strip
wires and tie together in a wire nut. (See Figure
16.)
2. Remove the rubber tubing from the pressure
switch sensor tube and the collector pan sen-
sor tube. Cut the tubing approximately 3" from
one end. Select the appropriate dilution cover
plate as noted with vent kit #903196. Insert the
bleed tube into the tubing. Do not cover the
hole in the bleed tube. Place the tubing
assembly back on the pressure switch sensor
tube and collector pan sensor tube. (See Figure
17.)
3. To gain access to the restrictor plate, remove
and discard the combustion tube from the
transition assembly. Insure the seal between
inducer and transition assembly is not
broken. (See Figure 18.)
4. Remove and discard the restrictor plate and
screw from the transition assembly. (See Fig-
ure 18.)
5. Install andseal a4" to3" reducerto thetransition.
(See Figure 19.) Attach the new high tempera-
ture vent pipe to the reducer.

1 horizontal kit is certified for use
1. Apply an adhesive bead around the
outside of the pipe approximately 1/4"
from the end of the pipe. This includes
the first fitting or pipe attached to the
furnace.
2. Push the pipe and fitting together while
twisting the pipe or fitting. Twisting the
pipe or fitting spreads the adhesive
completely within the fitting socket.
3. When the pipe is at the socket bottom,
inspect the joint. Look for a complete,
uninterrupted ring of adhesive material
around the pipe at the fitting socket.
Additional adhesive or rotation of the
pipe or fitting may be required for a
complete seal. The complete adhesive
material ring provides the seal required
for the positive pressure vent.
4. All vent systems must include a tee and
drain plug for collection and disposal of
condensate. The drain tee must be
installed within the first 5 feet of vent run
to protect the furnace.
5. All horizontal sections must have a
slope toward the drain tee of not less
than 1/4" per foot to prevent the collection
of condensate at any location other than
at the tee.
6. Horizontal runs must be supported with
3/4" pipe strap at a maximum of 5 foot
intervals and at each point where an
elbow is used.
7. Maintain a 6 inch minimum air space to
combustibles from all sections of the
stainless steel vent system, except
when a wall thimble is used.
with this furnace. The kit includes a power
venter, a side-wall vent hood and a barometric
draft control. It has an electrical interlock to
assure that the furnace will not operate when
the power venter is off.
The kit is for use only when exhaust is through
an exterior wall, normally with horizontal vent
piping. The power venter establishes negative
pressure in the vent piping and the furnace
operates as if connected to Category I vertical
venting.
Installation Instructions are provided with the
kit. Installation must conform to those instruc-
tions and applicable requirements of local codes.
!WARNING:
The entire vent system must be sealed
with a high temperature sealant which
will withstand temperatures of 450°F.
