Installing without a Wall Sleeve
Refer to the following directions and Figure 1 for guidance
in installing the unit without a wall sleeve:
1. Measure the size of the unit and provide an opening
in an outside wall that will accept the unit. Local
ordinances may require a steel lintel to support the
wall above the opening. The opening must be square
in all four corners.
2. Position the unit so that the grilles on the outside face
of the unit are ush or extend beyond the face of the
exterior wall, but not recessed more than 2” from the
face of the building. Provide a support under the unit,
inside the building. Make sure that the inside support
does not block the return air. The unit should be
installed level or pitched slightly to the outside of the
building so that rain water will drain away.
3. Seal the space between the unit and building opening
using a non-hardening caulking compound. The seal
must be weather-tight to prevent entrance of moisture
and water into the building. Make sure the drain holes
in the base are not plugged with caulking.

Furnace Condensate Drain
The HWC9 furnace is provided with an internal condensate
drain and drain tting. A street elbow, a hose barb and a
spigot adapter for connection to the drain tting are factory-
supplied in the manual bag. All other piping is eld-supplied
to suit the installation and local codes.
If the furnace is installed in an unconditioned space, the
condensate drain elbow outside the unit cabinet must
have heat tape suitable for PVC pipe installed, and the
elbow insulated. This heat tape and insulation are eld-
supplied from standard hardware items that are available
locally, and they must be installed in accordance with the
instructions provided by their manufacturers.
Units are shipped with the drain tting installed for side-exit
condensate drainage. The drain tting can be repositioned
for front-exit condensate drainage if desired. Do not
relocate or remove the internal condensate trap.
If unit will be started immediately upon completion of
installation, the drain must be primed as described in the
procedure outlined in the “Start-up” section.
Field-installed piping from the furnace must slope downward
a minimum of 1/2” per foot toward the oor drain.
Piping for Side-Exit Condensate Drain
Determine whether the installation better suits a side-exit or
a front-exit furnace condensate drain. For side condensate
drain, see Figure 3 for component locations and additional
details. A 2” clearance to the cabinet side is required for
service access to the condensate drain tting when using
the side location.
1. Install the factory-supplied street elbow to the drain
tting by threading into place. Use a thread sealant
suitable for PVC; do not use thread tape.
2. Use the appropriate primer and solvent cement to
bond eld-supplied drain line piping or ttings to the
PVC street elbow. Do not use copper tubing or existing
copper condensate lines for drain line.
3. Route the piping to an open oor drain. Do not connect
directly to evaporator condensate drain line.
Piping for Front-Exit Condensate Drain
For front condensate drain, see Figure 4 for component
locations and additional details. Use the factory-supplied
hose barb with eld-supplied exible tubing or spigot and
hose coupling for these installations. A 2” or 4”(depending
of choice of ttings) clearance to the cabinet front is
required for service access when using the front location.
The modications necessary to convert to front-exit
condensate drain are:
1. Disconnect the lower drain hose from the drain tting.
2. Remove the screw securing the drain tting to the
division panel.
3. Remove the drain tting and rotate it so that it faces
the front of the furnace.
4. Replace the securing screw.
5. Disconnect lower drain hose from drain trap and rotate
the hose so that the angled end will connect to the
drain tting in its new orientation.

exible tubing and route to an open oor drain. Secure
the end of the tubing to the drain. Do not connect
directly to evaporator condensate drain line.
12. For the spigot adapter, attach the provided rubber
coupling and then route 3/4” PVC pipping to an open
oor drain. Do not connect directly to evaporator
condensate drain line.
Combustion Air
This unit is a direct-vent furnace which obtains all air
needed for combustion from outdoors.
Insufcient combustion air can cause headaches,
nausea, dizziness or asphyxiation. It will also cause
excess water in the heat exchanger resulting in rusting
and premature heat exchanger failure. Excessive
exposure to contaminated combustion air will result
in safety and performance related problems. Avoid
exposure to the following substances in the combustion
air supply:
• Permanent wave solutions
• Chlorinated waxes and cleaners
• Chlorine base swimming pool chemicals
• Water softening chemicals
• De-icing salts or chemicals
• Carbon tetrachloride
• Halogen type refrigerants
• Cleaning solvents (such as perchloroethylene)
• Printing inks, paint removers, varnishes, etc.
• Hydrochloric acid
• Antistatic fabric softeners for clothes dryers
• Masonry acid washing materials
WARNING
Venting
The venting system is an integral part of the appliance.
The venting system must not be modied or added on
to.
The unit contains a combustion inducer. The inducer
draws the combustion products out of the heat exchanger
and forces them from the unit to the outside. No special
provisions are required for supplying air for combustion,
nor is a chimney required.
The vent outlet must not be altered or extended.
The venting system is designed for proper operation under
all weather conditions and for winds up to 31 m.p.h.
Removal of Unit from Common Venting System
When an existing furnace is removed from a common
venting system serving other appliances, the venting
system is likely to be too large to properly vent the
remaining attached appliances. The following test
should be conducted with each appliance while the other
appliances 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 deciencies
which could cause an unsafe condition.
3. Insofar as is practical, close all building doors and
windows between the space in which the appliances
remaining connected to the common venting system
are located and other spaces in the building. Turn on
clothes dryers and any appliance not connected to the
common venting system. Turn on exhaust fans, such
as range hoods and bathroom exhausts, so they will
operate at maximum speed. Do not operate a summer
exhaust fan. Close replace dampers.
4. Following the lighting instructions, place the unit being
inspected in operation. Adjust the thermostat so the
appliance will operate continuously.
5. Test for spillage at the draft control relief opening after
5 minutes of main burner operation. Use the ame of
a match or candle.
6. Follow the preceding steps for each appliance
connected to the common venting system.
7. After it has been determined that each appliance
remaining connected to the common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fans, replace dampers,
and any other fuel burning appliance to their previous
condition of use.

Page 7 of 20507389-02 Issue 1733
8. If improper venting is observed during any of the
above tests, the common venting system must be
corrected. See National Fuel Gas Code, ANSI Z223.1
(latest edition) or CAN/CGA B149.1 & .2 Canadian
Installation Codes to correct improper operation of
common venting system.
Gas Connections
The gas line to the unit should be adequately sized to
prevent undue pressure drop and should never be smaller
than the manual valve used. Consult the local utility or
National Fuel Gas Code for complete details on special
requirements in sizing gas piping.
The units supplied for operation with natural gas contain
a gas regulator which must be operated with inlet gas
pressures specied on the rating plate. If gas line pressure
exceeds this gure, an additional high pressure regulator
must be installed to reduce this pressure.
Units for operation with propane must be converted with a
kit supplied by the manufacturer and require for operation
an inlet pressure of 11” W.C. minimum and 13” W.C.
maximum. A regulator is also required on the propane tank.
If a exible gas connector is required or allowed by
the authority that has jurisdiction, black iron pipe shall
be installed at the gas valve and extend outside the
furnace cabinet. The exible connector can then be
added between the black iron pipe and the gas supply
line.
CAUTION
Compounds used on threaded joints of gas piping must
be resistant to the actions of liquied petroleum gases.
IMPORTANT
Never use a ame to check for gas leaks. Explosion
causing injury or death may occur.
CAUTION
If local codes allow use of a exible gas connector, a new
listed connector must be used. Do not use a connector
which has previously serviced another gas appliance.
A manual shutoff valve must be located outside the unit.
The use of a union located upstream of the controls is
recommended; between the controls, and the manual
shutoff valve. This will facilitate removal of controls and
manifold. See Figure 5 for recommended placement of the
union.
Provide a drip leg in the supply piping located exterior
to the unit. Piping connections must be sealed with non-
hardening pipe joint compound resistant to propane.
The furnace must be isolated from the gas supply piping
system by closing the individual manual shutoff valve
during any pressure testing of gas supply piping system
at test pressures equal to or less than 1/2 psig or 14”
W.C. If the piping system is to be tested at pressures
in excess of 1/2 psig, the furnace and its individual
shutoff valve must be disconnected from the gas supply
piping system. The gas valve supplied with this furnace
is rated at 1/2 psig. Any higher pressure may rupture
the pressure regulator diaphragm which will cause
overring of the burners and improper burner operation.
This action may produce a high concentration of carbon
monoxide which can result in asphyxiation.
WARNING
Figure 5. Gas Supply Piping
Leak Check
After gas piping is completed, carefully check all piping
connections (factory and eld installed) for gas leaks. Use
a leak detecting solution or other preferred means.
NOTE: If emergency shutoff is necessary, shut off the main
manual gas valve and disconnect the main power to the
furnace. The installer should properly label these devices.
Some soaps used for leak detection are corrosive to
certain metals. Carefully rinse piping thoroughly after
leak test has been completed. Do not use matches,
candles, ame or other sources of ignition to check for
gas leaks.
CAUTION

Electrical Connections
ELECTROSTATIC DISCHARGE (ESD)
Precautions and Procedures
All wiring must be done in accordance with the National
Electrical Code, ANSI/NFPA No. 70 (latest edition);
Canadian Electrical Code Part 1, CSA C22.1 (latest
edition); or local codes, where they prevail. Any alteration
of internal wiring will void certication and warranty.
Electrostaticdischarge can affectelectroniccomponents.
Take precautions during furnace installation and service
to protect the furnace’s electronic controls. Precautions
will help to avoid control exposure to electrostatic
discharge by putting the furnace, the control and
the technician at the same electrostatic potential.
Neutralize electrostatic charge by touching hand and
all tools on an unpainted unit surface, such as the gas
valve or vestibule panel, before performing any service
procedure.
CAUTION
The rating plate indicates the operating voltage, phase,
minimum circuit ampacity, maximum fuse size, and
minimum voltage. Units must never be installed where
voltage exceeds 10% over the voltage indicated on the
rating plate.
Units are factory wired for a 230 volt power supply. If
power supply is 208 volts, it will be necessary to change a
wire connection on unit transformer from 240 volt terminal
to 208 volt terminal as shown on the wiring diagram.
Failure of the compressor as a result of operation on
improper voltage voids the compressor replacement
warranty.
Aseparate electric line with wire having a temperature rating
of 60°C should be run directly from the main supply panel
to the leads in the unit. Refer to the rating plate located on
the unit for proper fuse or breaker size. Make sure the unit
is electrically grounded in accordance with local codes or,
in the absence of local codes, with the National Electrical
Code, ANSI/NFPA No. 70 (latest edition) for installations
in the U.S. or the Canadian Electrical Code Part 1, CSA
C22.1 (latest edition) for installations in Canada.
See rating plate for minimum wire ampacity, and size wire
accordingly.
Exterior Junction Box and Switch
If local codes allow, a eld supplied junction box and
optional switch may be installed on the top panel to provide
an exterior electrical wiring point and disconnect. A suitable
junction box cover must be used. If a switch is used it must
meet or exceed the electrical specications shown on the
unit rating plate. The junction box, cover, and (if used)
switch are standard items that are locally available.
Installing an Exterior Junction Box
1. Remove the two screws that secure the factory-
supplied cover over the rear half of the internal junction
box. Keep the front cover in place. See Figure 6.
2. Position a 4x4 junction box over the opening as shown
in Figure 7. Make sure the junction box is pulled up
against the front cover so that there is no gap. Remove
a knock-out in the box to allow the unit wiring leads
to extend into the bottom of the box. Pull the leads
through the knock-out and into the box. Remove a
knock-out for the main power supply leads.
3. Secure the junction box to the top panel using screws.
4. Connect the unit wiring leads to the main power supply
or the switch as desired. Securely attach the cover to
the junction box. When complete, the junction box

Provide duct(s) sized sufciently to handle the larger of the
air volumes for heating or cooling provided by this model.
Connect the supply duct to the top of the unit using canvas
connections or other exible connections to prevent noise
transmission into the duct system.
To connect the return duct to the system, use a straight
piece of duct 22” wide by 6” deep. Insert the duct into the
return opening in the bottom of the unit and ange the
duct over the existing anges around the opening inside
the unit. Make sure that all sides of the duct are anged
over to permit removal of the cooling chassis if required.
Use a exible connection to attach the remainder of the
return duct. The return duct should be sealed to the unit
casing and must terminate outside the space containing
the furnace.
Adjustments – Heating Section
Temperature Rise
At time of installation, the temperature rise must be
adjusted to be within the range specied on the unit rating
plate. See Table 2. Select a lower blower speed to increase
rise. Select a higher blower speed to reduce rise.
Pressure Regulator
The gas input must not exceed the gures shown on the
rating plate. The unit is equipped for rated inputs with
manifold pressures of: 3.5” W.C. for natural gas and 10.0”
W.C. for propane.
The manifold pressure can be measured by removing the
pipe plug in the automatic gas valve. Connect a water
manometer and measure the pressure. See Figure 9.
Only small variations in gas input may be made by adjusting
the regulator. In no case should the nal manifold pressure
vary more than 0.3” W.C. for natural gas or 0.7” W.C. for
propane.
To adjust the regulator, turn the adjusting screw on the
regulator clockwise to increase pressure and input or
counterclockwise to decrease pressure and input.
