INSTALLATION AND MAINTENANCE INSTRUCTIONS
Gas Heating/Electric Cooling Package Unit
Improper installation, adjustment, alteration, service, or maintenance can cause injury
or property damage. Refer to this manual. For assistance or additional information,
consult a qualified installer, service agency, or the gas supplier.
WARNING
Do not store combustible materials, including gasoline
and other flammable vapors and liquids, near the furnace,
vent pipe, or warm air ducts. Such actions could cause
property damage, personal injury, or death.
WARNING
Never use a flame to check for gas leaks. Explosion
causing injury or death may occur.
If this unit is to be installed in a mobile or manufactured
home application, the ductwork must be sized to achieve
static pressures within the manufacturer's guidelines.
All other installation guidelines must also be followed.
Failure to do so may result in equipment damage,
personal injury, and improper performance of the unit.
The installation of the furnace, wiring, warm air ducts, venting, etc. must conform to the requirements of the National Fire
Protection Association; the National Fuel Gas Code, ANSI Z223.1 (latest edition) and the National Electrical Code, ANSI/
NFPA No. 70 (latest edition) in the United States; the Canadian Installation Codes CAN/CGA-B149.1 & .2 (latest edition)
and the Canadian Electrical Code Part 1, CSA 22.1 (latest edition) in Canada; and any state or provincial laws, local
ordinances, or local gas utility requirements. Local authorities having jurisdiction should be consulted before installation
is made. Such applicable regulations or requirements take precedence over the general instructions in this manual.

SAFETY The following is a list of safety rules and precautions that must be followed when installing this furnace. 1. Use only with the type of gas approved for this furnace. Refer to the furnace rating plate. 2. Install this furnace only in a location and position as specified in the Location section on page 3 of these instructions. - Page 3 Location Use the following guidelines to select a suitable location for the unit. 1. Unit is designed for outdoor installation only. Unit must be installed so all electrical components are protected from water. 2. Condenser coils must have an unlimited supply of air. 3.
- Page 4 Roof Curb Installation If a roof curb is used, follow the manufacturer’s Installation Instructions and be sure that all required clearances are observed (see following Clearances section). Roof Curb Assembly Figure 2 Clearances All units require certain clearances for proper operation and service.
- Page 5 a sidewalk, patio, or other walkway where the condensate could cause the surface to become slippery. The products of combustion must not be allowed to accumulate within a confined space and recirculate. Vent Hood The unit is shipped with the vent hood, screen, and sheet metal screws packed in the plastic bag containing the Installation Instructions.
- Page 6 Condensate Drain The PGE/SG package unit is equipped with a 3/4" FPT coupling for condensate line connection. Plumbing must conform to local codes. Use a sealing compound on male pipe threads. The condensate drain line must be properly trapped and routed to a suitable drain.
- Page 7 Minimum Required Surface Area for Disposable Filters Table 2 The gas supply line should be routed through the grommet on the side of the unit. Refer to Figure 7 to locate this access opening. If local codes allow the use of a flexible gas appliance connector, always use a new listed connector.
- Page 8 WARNING Any conversion of a natural gas unit to propane gas must be done by qualified personnel using a conversion kit available from the manufacturer, following the instructions in the conversion kit. If done improperly, overfiring of the burners and improper burner operation can result. This can create carbon monoxide which could cause asphyxiation.

Page 11: Operation
For Natural Gas: Check the gas input rate by observing the gas meter, when available, making sure all other gas appliances are turned off. The test hand on the meter should be timed for at least one revolution. Note the number of seconds for one revolution. - Page 12 Insure unit is installed per manufacturer’s instructions and that line voltage and air flows are correct. Refer to Table 3 for proper superheat or subcooling values. Check superheat settings by measuring pressure at the suction line service port. For TXV systems, measure pressure at the liquid service port.

Variable Speed Motor Units equipped with a variable speed circulation air blower motor will deliver a constant airflow within a wide range of external static pressures. Other features of this variable speed motor include: Soft Start/Stop – The variable speed motor will slowly ramp up to normal operating speed. -
Page 14: Control System Diagnostics
Burners Light the burners and allow to operate for a few minutes to establish normal burning conditions. Observe the burner flames. Compare this observation to Figure 10 on page 14 to determine if proper flame adjustment is present. Flame should be predominantly blue in color and strong in appearance. -
