Product Data ComfortTM 92 Model 58MXA Highly-Efficient 4-Way Multipoise Fixed-Capacity Direct-Vent Deluxe Condensing Gas Furnace Input Capacities: 40,000 thru 138,000 Btuh 4-Way Multipoise Design Allows More Applications. The Comfort 92 is a must for your product line. This high-efficiency furnace allows more applications with its reliable 4-way multipoise design. The Comfort 92 is available in 12 heat/ airflow combinations and with the 4way multipoise design can be installed in upflow, downflow, or horizontal positions covering up to 48 different applications.

With the exception of the 140 size unit, all Comfort 92 models can be installed in a manufactured (mobile) home when the optional kit is used, and in installations with elevations up to 10,000 ft (140 size unit limitation 7,000 ft). The furnace is factory configured for upflow application. 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 Comfort 92. Control of ignition, inducer, and blower operation is all handled in 1 central printed circuit board. The status indicator on the control signals when a fault has occurred and identifies where the problem is. This, along with the component test feature, makes the Comfort 92 one of the easiest gas furnaces to troubleshoot. High efficiency is achieved by maximizing heat transfer. The Comfort 92 uses 100 percent outdoor air for combustion in a sealed-combustion system. The result is energy-saving efficiency, up to 95.5 percent (Pg. 12) Annual Fuel Utilization Efficiency (AFUE), and reduced operational noise. The Comfort 92 is one of the quietest furnaces in the industry. A unique feature of this unit is the patented polypropylene-laminated 2003 Carrier Corporation Form 58MXA-11PD 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.) When we put it all together, the Comfort 92 combines quality and design to bring high efficiency and comfort. You will enjoy the versatility and ease of installation of this unit. The Comfort 92 is equipped for either left- or right-side connections. Blower speeds are easily adjustable with speed-taps conveniently located on the control center. An updated, 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. motor noise to promote quiet operation.

A CSA (A.G.A./C.G.A.) listed gas conversion kit is required to convert furnace for use with propane gas. The efficiency is GAMA efficiency rating certified. The Comfort 92 meets California Air Quality Management District emission requirements. Except for the 140 size unit, all Comfort 92 models can be installed in a manufactured (mobile) home when the optional kit is used. Refer to Vent Table, pg. 15, for elevation limitations. Warranties — Limited Lifetime Warranty on the heat exchangers for the lifetime of original owner in single family residence; 20 years in other residential and commercial applications.
