The furnace is factory configured for upflow application. The versatility of this furnace is further enhanced by its dual venting capability. The PerformanceTM 93 can be installed as 1-pipe/Non-Direct vent or 2-pipe/Direct Vent. This versatile unit utilizes hot surface ignition (HSI) which ignites the burners directly. HSI eliminates gas waste that typical continuous-pilot designs can bring. Hot surface ignition provides reliable start-up and operation. Take a look at the control center on the PerformanceTM 93. Control of ignition, inducer, and blower operation is all handled in 1 central printed circuit board. The status indicator on the control signals when an event has occurred and identifies where the event is. This, along with the component test feature, makes the PerformanceTM 93 one of the easiest gas furnaces to troubleshoot. A unique feature of this unit is the patented polypropylene-laminated heat exchanger. This secondary heat exchanger ensures that all available heat is properly transferred to the airstream and throughout the home. Using the exclusive flow-through design, the secondary heat exchanger reduces the pressure drop in the furnace which leads to lower electrical usage, an important part of this unit’s efficiency. Carrier heat exchangers are backed by a Limited Lifetime Warranty. (See Warranties section for details.) Catalog No. 58MTB-1PD A05069 2005 Carrier Corporation When we put it all together, the PerformanceTM 93 combines quality and design to bring high efficiency and comfort. You will enjoy the versatility and ease of installation of this unit. The PerformanceTM 93 is equipped for either left- or right-side connections. Blower speeds are easily adjustable with speedtaps conveniently located on the control center. A more efficient combustion inducer allows for more use of 2-in. vent and combustion-air piping, keeping installation costs low. As with other Carrier furnaces, this model is designed to work as a part of the total home comfort system which includes elements for cooling, air cleaning, humidification, ventilation, and zoning. THE PERFORMANCETM 93 FEATURES/BENEFITS ComfortHeatTM Technology–The PerformanceTM 93 has a 2-stage gas valve to vary the amount of gas being used from low-heat to high-heat stage. The low-stage operation allows longer running periods, which helps maintain your most comfortable temperature, prevents drafts, reduces noise, and enhances the air quality of your home. During the extreme cold, the high-heat levels will run to ensure that you are still comfortable. Primary Heat Exchanger & SerpentuffTM Secondary Heat Exchanger — The primary heat exchanger is corrosion resistant and maintains a proven track record for longterm reliability and high-efficiency performance. The secondary heat exchanger is built with a patented lamination process that bonds a corrosion-proof lining of polypropylene to a heavy, galvanized steel shell. The unique secondary clamshell design allows wider spacing between cells for reduced air resistance through the furnace, reduced load on the blower motor, and reduced need for cleaning.
