Installation, Start-Up and Service Instructions

NOTE: Read the entire instructions before starting the

installation.

INTRODUCTION

Before installing the furnace, refer to “Procedures for Natural-Draft Gas-Fired Furnaces” (packaged with the equipment) for information concerning combustion, venting, piping, and other standeird installation practices. Further reference is made to the current edition of the National Fuel Gas Code NFPA No. 54-1988/ANSI Z223.1-1988.

Reference should also be made to the regulations of the

serving gas supplier and the local building, heating, plumb ing, or other codes in effect in the area in which the installa tion is made.

SAFETY CONSIDERATIONS

Installation and servicing of heating equipment can be haz ardous due to gas and electrical components. Only trained and qualified personnel should install, repair, or service heating equipment.

Untrained personnel can perform basic meuntenance func tions such as cleaning and replacing air filters. AU other operations must be performed by trained service personnel, when working on heating equipment, observe precautions in the literature, tags, and labels attached to or shipped with the unit and other safety precautions that may apply.

Follow all safety codes, including NFPA No. 54/ANSI

Z223.1-1988, National Fuel Gas Code. Wear safety glasses and work gloves. Have fire extinguisher available during startup and adjustment procedures and service call.

Recomized safety information: This is the safety-alert sym bol A. When you see this symbol on the furnace and in instructions or manueils, be alert to the potential for per sonal injury.

Understand the signal word—DANGER, WARNING, or CAUTION. These words are used with the safety-alert sym bol. DANGER identifies the most serious hazards which

will result in severe personal injury or death. WARNING

on the other hand could result in personal injury or death.

CAUTION is used to identify unsafe practices, which would result in minor personal injury or product and property damage.

Each furnace is shipped from the factory completely assem bled with multispeed direct-drive blower and wired ready for downflow indoor heating installation only. AU sizes feature a printed-circuit board control center with easy-to-read, 24volt terminal strip to ensure proper connections.

design-certified for use with the vent damper specified on the furnace rating plate. See instructions packaged with the vent deunper for its installation.

A CAUTION

Application of this furnace should be indoors with spe cial attention given to vent sizing and material, gas input rate, air temperature rise, and unit sizing. Improper installation or misapplication of the furnace can require excessive servicing or cause premature com ponent failure.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

A CAUTION

Do not insteill furnace in a damp, corrosive, or contami

nated atmosphere. Make sure all combustion and circu lating air requirements listed in “Procedures for Natured-Draft Gas-Fired Furnaces” are adhered to, in addition to all local codes and ordinances.

Do not use this furnace during construction when adhe sives, sealers and/or new carpets are being installed. If the furnace is required during construction, use clean outside air for combustion and ventilation. Compounds of chlorine and fluorine when burned with combustion air form acids which wiU cause corrosion of the heat exchangers and metal vent system. Some of these com pounds are paneling and dry wall adhesives, paints, thinners, masonry cleaning materials, and many other solvents commonly used in the construction process.
