Gas-Fired Forced-Air Furnace
with Electronic Ignition
INSTALLATION
Before installing the furnace, refer to “Pro cedures for Gas-Fired Furnaces” (packaged with the equipment) for information concerning com bustion, venting, piping, and other standard instal lation practices. Further reference is made to the current edition of the American National Standard Z223.1 National Fuel Gas Code.
Each furnace is shipped from the factory com pletely assembled with multispeed direct-drive blower and wired ready for indoor heating installa tion. All sizes feature a printed-circuit board control center with easy-to-read low-voltage terminal strip to ensure proper connections. The control center also provides easy connections for line-voltage air cleaners.
CAUTK)?i : Do not iosiaB famace in a corrosive or contasninated atmospheres Miakesnre that ail local ordinances for combnstion and oircalating air supply axe observed.

The design of the upflow gas-fired furnaces is A.G.A. certified for installation on combustible flooring in alcoves, basements, closets, or utility rooms.
For accessory installation details, i.e., automatic vent damper, humidifier, electronic air cleaner, etc., refer to applicable installation literature.
Electrical Connections
LINE VOLTAGE WIRING
IMPORTANT: Before proceeding with the elec trical connections, make certain that voltage, frequency, and phase correspond to that specified on the unit rating plate. Also, check to be sure that the service provided by the utility is sufficient to handle the additional load imposed by this equip ment. Refer to the unit rating plate for equipment electrical requirements.

CAUTION: Use copper or copper-dad aluiainum conductors only. Use a separate branch electrical circuit for this furnace. A disconnect ing means must be located within sight of, and readily accessible to, the furnace.
See Fig. 2 for wiring diagram showing the proper field highand low-voltage wiring. Make all elec trical connections in accordance with the National Electrical Code and any local codes or ordinances that might apply.
WARNING: The unit cabinet m.ust have an uninterrupted or unbroken electrical ground to minimize personal injury if an electrical fanlt should occur. This may consist of electrical wire or approved conduit when installed in accordance with e.Kisting electrical codes.
LOW-VOLTAGE WIRING — Make field lowvoltage connections at the low-voltage terminal strip. See Fig. 2.
Set the thermostat heat anticipator at the settings indicated below. If additional controls are connected in the thermostat circuit, their amp draw must be added to this setting. Failure to make the setting will result in improper operation of the thermostat.

exposed to cold air infiltration, drafts from win dows, doors, or other openings leading to the out side, or exposure to air currents from warm or cold air registers; or to exposure where the natural circu lation of the air is cut off — such as behind doors, above or below mantels, shelves, etc.
The thermostat should not be exposed to heat from nearby fireplaces, radios, televisions, lamps, or rays from the sun. Nor should the thermostat be mounted on a wall containing pipes or warm air ducts, or a flue or vent that could affect its operation and prevent it from properly controlling the room temperature. Any hole in the plaster or panel thru which the wires pass from the thermostat should be adequately sealed with suit able material to prevent drafts from affecting the thermostat.
