INTRODUCTION

The model 58ZAV Series 140 Furnaces are available in sizes 46,000 through 135,000 Btuh input capacities.

The design of the downflow/horizontal gas-fired furnace is A.G.A./C.G.A. certified for natural and propane gases and for installation on noncombustible flooring. The furnace is factory- shipped for use with natural gas. A factory accessory gas conver- sion kit, as listed on the furnace rating plate is required to convert furnace for use with propane gas.

These furnaces SHALL NOT be installed directly on carpeting, tile, or any other combustible material other than wood flooring. In downflow installations, a factory accessory floor base, as listed on the furnace rating plate MUST be used when installed on com- bustible materials and wood flooring. A factory base is not required when this furnace is installed on manufacturer's Coil Assembly Part No. CD5 or CK5, or when Coil Box Part No. KCAKC is used. This furnace is for installation in alcoves, attics, crawlspaces, basements, closets, or utility rooms. The design of this furnace line is not A.G.A./C.G.A. certified for installation in mobile homes, recreation vehicles, or outdoors.

Before installing the furnace in the United States, refer to the current edition of the NFGC and the NFPA 90B. For further information, the NFGC and NFPA 90B are available from Na- tional Fire Protection Association Inc., Batterymarch Park, Quincy, MA 02269; or the American Gas Association, 400 N. Capitol St., NW, Washington DC 20001.

→Before installing the furnace in Canada, refer to the current edition of the NSCNGPIC. For a copy of the NSCNGPIC, contact

Standard Sales, CSA International, 178 Rexdale Boulevard, Eto- bicoke (Toronto), Ontario, M9W 1R3 Canada.

Installation must comply with regulations of serving gas supplier and local building, heating, plumbing or other codes in effect in the area in which installation is made. In absence of local building codes, installation must conform with NFGC in the United States and the NSCNGPIC and all authorities having jurisdiction in Canada.

These instructions cover minimum requirements for a safe instal- lation and conform to existing national standards and safety codes. In some instances, these instructions exceed certain local codes and ordinances, especially those that may not have kept pace with changing residential construction practices. We require these instructions as a minimum for a safe installation.

Application of this furnace should be indoors with special 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 component failure.

NOTE: These furnaces are designed for a minimum continuous return-air temperature of 60°F or intermittent operation down to 55°F such as when used with a night setback thermostat. Return-air temperature must not exceed a maximum of 85°F. Failure to follow these return-air temperature limits may affect reliability of heat exchangers, motors, and controls.
