operation of the unit with clogged or misplaced lters will

damage the unit.

Units may be used for heating of buildings or structures

under construction, if the following conditions are met:

• The unit must be permanently installed per these

installation instructions.

• A room thermostat must control the furnace. The use

of xed jumpers that will provide continuous heating is

not allowed.

• The return air duct must be provided and sealed to the

furnace.

Page 4 of 19 507388-03Issue 2127

• Return air temperature range between 60°F (16°C)

and 80°F (27°C) must be maintained.

• Air lters must be installed in the system and must be

maintained during construction.

• Air lters must be replaced upon construction

completion.

• The input rate and temperature rise must be set per

the furnace rating plate.

• One hundred percent (100%) outdoor air must be

provided for combustion air requirements during

construction.

• The furnace heat exchanger, components, duct

system, air lters and evaporator coils must be

thoroughly cleaned following nal construction clean-

up.

• All furnace operating conditions (including ignition,

input rate, temperature rise and venting) must be

veried according to these installation instructions.

Installing With a Wall Sleeve

Refer to the installation instructions packed with the wall

sleeve and Figure 2 for guidance in assembly and mounting

using a wall sleeve.

• Make sure the gaskets attached to the sleeve are not

damaged.

• Seal the space between the wall sleeve and the building

opening with non-hardening caulking compound. The

seal must be weather-tight to prevent entrance of

moisture and water into the building.

• Assure that the unit is completely seated against the

gaskets on the wall sleeve.

• Slide the unit into the sleeve. When properly nested,

the angle on top of the unit should line up with the top

ange of the sleeve and should almost touch. Fasten

the unit to the sleeve with ve screws furnished with

the sleeve.

The sleeve is not intended as the sole support for the

unit. An additional support must be provided near the

return opening on the unit for adequate support. The

use of vibration isolation material between the unit and

the support is recommended.

Insu󰀩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

Combustion Air

This unit is a direct - vent furnace which obtains all air

needed for combustion from outdoors.

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

together with dilution air and forces the mixture 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.

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) 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 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.

Page 6 of 19 507388-03Issue 2127

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 liqueed petroleum gases.

IMPORTANT

Never use a ame to check for gas leaks. Explosion

causing injury or death may occur.

CAUTION

A manual shuto󰀨 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

shuto󰀨 valve. This will facilitate removal of controls and

manifold. See Figure 3 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 shuto󰀨 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 shuto󰀨

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 3. 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 shuto is necessary, shut o 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

507388-03 Issue 2127 Page 7 of 19

Electrical Connections

All wiring must be done in accordance with the National

Electrical Code, ANSI/NFPA No. 70 (latest edition); or local

codes, where they prevail. Any alteration of internal wiring

will void certication and warranty.

ELECTROSTATIC DISCHARGE (ESD)

Precautions and Procedures

Electrostatic discharge can a󰀨ect electronic components.

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.

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 4.

2. Position a 4x4 junction box over the opening as shown

in Figure 5. 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

should be as shown in Figure 6.

5. The rear cover that was removed in Step 1 is not used

and may be discarded.

where it will not be a󰀨ected by drafts, sunlight, or any other

heat producing appliances. Connect the thermostat wires

to the low voltage leads on top of the unit following the

wiring diagram attached to the unit. The heat anticipator

setting is 0.50 amp.

NOTE: For HWC8*30 models, a two-stage thermostat is

recommended for reaching highest eciency and full use

of two-stage compressor.

Air Filter

All indoor return air must be ltered. A permanent-type

lter is furnished with the unit, located directly behind the

access panel. Removing the panel permits access to the

lter. See Figure 3.

If an installation is made in which it is more desirable to

mount the lter exterior to the unit, in the return duct work

or elsewhere, the permanent lter can be used or replaced

with a disposable lter. If a disposable lter is used, refer

to the information provided in Table 1 when sizing the

disposable lter.

Supply and Return Duct(s)

Provide duct(s) sized su󰀩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 10.5”

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. See

Figure 9.

For natural gas installations, check the burner rate by

observing the gas meter (making sure that all other gas

appliances are turned o󰀨). The test hand on the meter

should be timed for at least one revolution. Note the

number of seconds for one revolution.

Adjustments – Cooling Section (HWC models)

No adjustments are required or should be attempted

regarding any of the components of the cooling chassis.

The chassis should be checked to see that none of the

wiring is loose or missing.

Cooling chassis is charged with R410A refrigerant.

Blower

The unit contains a direct-drive, multispeed blower. The

proper speeds have been preset at the factory for heating

and cooling. Refer to the wiring diagram or Table 2 for

recommended heating/cooling speeds for specic models.

Direct-drive blower motors are permanently lubricated and

do not require oiling.

Limit Control

A xed temperature limit control is provided which will shut

o󰀨 the gas to the main burners if the unit is overheated for

any reason. The control must not be adjusted or relocated.

High Altitude Adjustments (U.S. Installations)

Ratings shown on the rating plate are for elevations up to

2000 feet. For elevations above 2000 feet, ratings should

be reduced at a rate of 4% for each 1000’ above sea level.

Refer to the National Fuel Gas Code Z223.1 (latest edition)

for further explanation.

Installation and Operation in Extremely Cold

Weather Areas

In areas where extremely cold (below – 20°F) outdoor

temperatures can be expected, some additional installation

and operating precautions should be taken. The following

precautions are taken to prevent possible vent system

ice blockage that could result in safety shutdown of the

burners:

1. Adjust to the highest achievable temperature rise

within the rise and static pressure ranges specied

on the rating plate. Depending on specic model, it

may be possible to change to a lower heating blower

speed tap to get a higher temperature rise. This also

increases comfort.

2. Make sure there are no leaks of outside air into the

return air system.

3. Keep the outside louver grille as free as possible of

any ice that may form and obstruct the ue outlet.
