1.
CAUTION
During the initial firing of the burners there will probably be some amount of smoke issued to the
circulating air stream as the result of residual oil burning off of the heat exchanger tubes. This oil
is required during the forming process of the stainless steel heat exchanger tubes to facilitate the
bending. OSHA or the National Toxicology Program does not list the oil as a carcinogen. In
vapor form this may be irritating to the eyes or could cause headaches. This is a one-time
occurrence, and ventilation of the space may be required depending upon the space being
conditioned.
1. IMPORTANT
The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians. All duct work or portions thereof not in
the conditioned space should be properly insulated in
order to both conserve energy and prevent condensation
or moisture damage.
2. APPLICATION
This is a fan-assisted forced air gas furnace with
electric air conditioning for outdoor installation. A
fan-assisted furnace is equipped with an integral
mechanical means to draw products of combustion
through the combustion chamber and heat exchanger.
The furnace installation must conform with local
building codes and ordinances or, in their absence, with
the National Fuel Gas Code ANSI Z223.1 or CAN/
CGA-B149.1, latest edition, and the National Electrical
Code ANSI/NFPA-7 or CSA C22.1, latest edition. It is
the personal responsibility and obligation of the
purchaser to contact a qualified installer to assure that
installation is adequate and is in conformance with
governing codes and ordinances.
3. DUCT WORK
The unit is designed for use with or without duct work.
See Warning on Page 9. Flanges are provided for
attaching the supply and return ducts. These
instructions explain the recommended method to install
the air cooled self-contained electric air conditioning
and gas heating unit and the electrical wiring
connections and gas piping to the unit. The refrigerant
system is completely assembled and charged. All
internal wiring is complete.
These instructions and any instructions packaged with
any separate equipment required to make up the entire
heating/cooling system should be carefully read before
beginning the installation. Note particularly “Starting
Procedure” and any tags and/or labels attached to the
equipment.
All duct work, supply and return, must be properly sized
for the design airflow requirement of the equipment.
Air Conditioning Contractors of America (ACCA) is an
excellent guide to proper sizing.
Refer to Table 9 in this Manual for maximum static
pressure available for duct design.

WARNING
In all cases, there must be a metal duct
connection made to the supply air flange, and
a one inch clearance to combustibles must be
maintained to this duct connection.
For free blow applications, a metal sleeve
must be used in the wall opening itself, again
maintaining a one inch clearance to
combustibles.
Failure to use the sheet metal can cause
fire resulting in property damage, injury, or
death.
4. HIGH ALTITUDE APPLICATIONS
Ratings of gas utilization equipment are based on sea
level operation and need not be changed for operation
at elevations up to 6,000 feet. For operation at
elevations above 6,000 feet and in the absence of
specific recommendations from the local authority
having jurisdiction, equipment ratings shall be reduced
as specified in Section 21.
5. TRANSPORTATION DAMAGE
All units are packed securely in shipping container.
All units should be carefully inspected upon arrival for
damage. In the event of damage, the consignee should:
1. Note on delivery receipt of any damage to container.
See Figure 3 and clearance information in Section 9
and Table 2 for additional information.
Design the duct work according to methods given by
the Air Conditioning Contractors of America (ACCA).
When duct runs through unheated spaces, it should be
insulated with a minimum of one-inch of insulation.
Use insulation with a vapor barrier on the outside of
the insulation. Flexible joints should be used to
connect the duct work to the equipment in order to
keep the noise transmission to a minimum.
A one-inch clearance to combustible material for the
first three feet of duct attached to the outlet air frame is
required. See Wall Mounting Instructions and Figures
2, 2A, 3 and 3A for further details.
Ducts through the walls must be insulated and all joints
taped or sealed to prevent air or moisture entering the
wall cavity.
Some installations may not require any return air duct.
A metallic return air grille is required with installations
not requiring a return air duct. The spacing between
louvers on the grille shall not be larger than 5/8 inch.
Any grille that meets with the 5/8 inch louver criteria
may be used. It is recommended that Bard Return Air
Grille or Return Filter Grille be installed when no
return duct is used. Contact distributor or factory for
ordering information. If using a return air filter grille,
filters must be of sufficient size to allow a maximum
velocity of 400 fpm.
NOTE: If no return air duct is used, applicable
installation codes may limit this cabinet to
installation only in a single story structure.
2. Notify carrier promptly, and request an inspection.
3. In case of concealed damage, the carrier must be
notified as soon as possible within 15 days after
delivery.
4. Claims for any damage, apparent or concealed,
should be filed with the carrier, using the following
supporting documents:
A. Original Bill of Lading, certified copy, or
indemnity bond.
B. Original paid freight bill of indemnity in lieu
thereof.
C. Original invoice or certified copy thereof
showing trade and other discounts or
deductions.
D. Copy of the inspection report issued by
carrier’s representative at the time damage is
reported to carrier.
6. INSTALLATION
Size of unit for proposed installation should be based
on heat loss/heat gain calculations made according to
methods of Air Conditioning Contractors of America
(ACCA). The air duct should be installed in
accordance with the Standards of the National Fire
Protection Association for the Installation of Air
Conditioning and Ventilating Systems of Other Than
Residence Type, NFPA No. 90A, and Residence Type
Warm Air Heating and Air Conditioning Systems,
NFPA No. 90B. Where local regulations are at a
variance with instructions, installer should adhere to
local codes.
Manual 2100-483E
Page 9 of 59
7. WALL MOUNTING INFORMATION
1. Two holes for the supply and return air
openings must be cut through the wall as
detailed in Figure 4.
2. On wood-frame walls, the wall construction
must be strong and rigid enough to carry the
weight of the unit without transmitting any unit
vibration.
WARNING
Failure to provide the one inch clearance
between the supply duct and a combustible
surface for the first three feet of duct can
result in fire causing damage, injury or death.
3. Concrete block walls must be thoroughly
inspected to insure that they are capable of
carrying the weight of the installed unit.
8. MOUNTING THE UNIT
1. These units are secured by wall mounting
brackets which secure the unit to the outside
wall surface at both sides. A bottom mounting
bracket is provided for ease of installation but
is not required.
CAUTION
If the bottom bracket is used, be certain the
bracket is secured to the outside wall surface
in a way sufficient to support the entire weight
of the unit during installation until side
mounting brackets are secured.
2. The WG3S1, WG4S1 and WG5S1 models are
suitable for 0 inch clearance on the installation
mounting wall and to the top. For all models the
supply air duct flange and the first 3 feet of
supply air duct require a minimum of 1-inch
clearance to combustible material.
3. Locate and mark lag bolt locations and bottom
mounting bracket location.
4. Mount bottom mounting bracket.
5. Hook top rain flashing under back bend of top.
Top rain flashing is shipped secured to the right
side of the back.
6. Position unit in opening and secure with 5/16
lag bolts; use 7/8 inch diameter flat washers on
the lag bolts. Use lag bolts long enough to
support the unit’s weight when mounted to the
structure. This length may be dependant on the
type of construction.
7. Secure rain flashing to wall and caulk across
entire length of top. See Figure 3.
8. On side-by-side installations, maintain a
minimum of 20 inches clearance on right side
to allow access to control panel and burner
compartment, and to allow proper airflow to the
outdoor coil. Additional clearance may be
required to meet local or national codes.

COMBUSTIBLE CLEARANCE
A minimum of one (1) inch clearance must be maintained between the supply air duct and combustible materials.
This is required for the first three (3) feet of ducting.
It is important to insure that the one (1) inch minimum spacing is maintained at all points.
Failure to do this could result in overheating the combustible material and may result in a fire causing damage,
injury or death.

9. CLEARANCES
Minimum clearances, as specified in Table 2, must be
maintained from adjacent structures to provide
adequate fire protection, adequate combustion air, and
room for service personnel.
While minimum clearances are acceptable for safety
reasons, they may not allow adequate air circulation
around the unit for proper operation in the cooling
mode. Whenever possible, it is desirable to allow
additional clearance, especially around the condenser
inlet and discharge openings. DO NOT install the unit
in a location that will permit discharged air from the
condenser to recirculate to the condenser inlet.

With the optional vertical venting kit (VVK-5) this unit
may be vented vertically through a roof or overhang.
The kit includes a stainless steel transition drain tee,
silicone sealant, and drain tubing.
If unit is installed with vertical vent kit, annually
inspect the vent system and drain. Replace any portion
of the vent system that shows signs of deterioration.
Make sure drain is open and free of obstruction.
CAUTION
Vent terminal must be installed as shown in Figure 8 for proper operation of the heating system.
NOTE: The inner vent hood gasket is designed to stretch over and seal around the combustion
air blower outlet. This is a very critical seal to prevent water and flue products from entering the
unit. Care must be taken to insure this gasket is in place and sealing properly.

12. VENT RESIZING INSTRUCTIONS
When an existing furnace is removed from a venting
system servicing other appliances, the venting system is
likely to be too large to properly vent the remaining
attached appliances.
The following steps shall be followed with each of the
appliances remaining connected to the common venting
system, placed in operation one at a time while the
other appliances remaining connected to the common
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 or the CAN/CGA B149
Installation Codes and these instructions. Determine
that there is no blockage or restriction, leakage,
corrosion and other deficiencies which could cause
an unsafe condition.
3. In so far as is 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. Turn on
clothes dryers and any appliances not connected to
the venting system. Turn on any exhaust fans, such
as range hoods and bathroom exhausts, so they will
operate at maximum speed. Do not operate a
summer exhaust fan. Close fireplace dampers.
13. FRESH AIR INTAKE
All units are built with fresh air inlet slots punched in
the service panel.
The default unit is built with blank-off plates installed.
All capacity, efficiency and cost of operation
information as required for Department of Energy
“Energyguide” Fact Sheets is based upon the fresh air
blank-off plate in place and is recommended for
maximum energy efficiency.
One of several other ventilation options may be
installed. Refer to model number and/or supplemental
installation instructions.
14. CONDENSATE DRAIN
A plastic drain hose extends from the drain pan at the
top of the unit down to the unit base. There are
openings in the unit base for the drain hose to pass
through. In the event the drain hose is connected to a
drain system of some type, it must be an open or vented
type system to assure proper drainage.
4. Follow the lighting instructions. Place the appliance
being inspected in operation. Adjust thermostat so
appliance shall operate continuously.
5. Test for draft hood equipped appliance spillage at the
draft hood relief opening after 5 minutes of main
burner operation. Use the flame of a match or
candle.
6. 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 gasburning appliances to their previous conditions of
use.
7. If improper venting is observed during any of the
above tests, the venting system must be corrected.
