58MCB 4-WAY MULTIPOISE FIXED-CAPACITY

CONDENSING GAS FURNACE

Input Rates: 40,000 thru 138,000 Btuh

Product Data

High Efficiency and Flexibility Designed to Meet the Needs of New Homes

The model 58MCB combines high efficiency with flexibility to meet the changing needs of new home construction. The unique 4-way, multipoise design of the 58MCB allows for installation in upflow, downflow, horizontal left, and horizontal right orientations, meaning it is perfect for a variety of installation applications. With the exception of the 140 size unit, all sizes of the 58MCB 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 but can easily be made ready for downflow or horizontal installation. With the exception of the 140 size, all sizes can be installed with 2-pipe or 1-pipe venting. The 140 size can be installed only as a 2-pipe system.

Horizontal applications offer the advantage of reduced space requirements by locating the furnace in an attic or crawlspace, freeing space formerly dedicated to a furnace or utility room.

The 58MCB is specifically designed to meet the needs of home builders and new home owners. Home builders benefit from the 58MCB’s unmatched flexibility and by building a reputation of using quality appliances in homes. Home owners benefit by energy savings from one of the most important home appliances.

The components of the 58MCB represent the finest in the industry. Hot surface ignition (HSI) and a control center provide reliable and efficient ignition. The combustion inducer is unique in that efficient operation is

achieved in any type of installation. Standard 2-in. PVC pipe connects the combustion-air and vent pipes to the furnace. The primary and secondary heat exchangers are backed by a 20-year Limited Warranty.

The 58MCB is a standard part of a quality-built new home. This highefficiency furnace will provide years of quality service to home builders and home owners alike.

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.

58MCB FEATURES/ BENEFITS

Serpentuff

coating, a patented polypropylene laminate is used on the secondary heat exchanger.

Power Heat™ Igniter —Carrier’s

unique SiN igniter is not only physically robust but it is also electrically robust. It is capable of running at line voltage and does not require complex voltage

—Exclusive Serpentuff

regulators as do other brands. This unique feature further enhances the reliability of the 58MCB gas furnace and continues Carrier’s tradition of technology leadership and innovation in providing a reliable and durable product.

Control Center —Controls sequencing

and furnace operation. Equipped with a component test feature and status indicator light to assist in troubleshooting. Control times blower start after main burners ignite to eliminate cold air blowing into rooms.

Warranties —20-year Warranty

on the heat exchangers. Fiveyear Warranty on entire unit. Contact your dealer for details.

Direct or Non-direct Venting —The

58MCB can be installed as a 1 pipe-NonDirect vent or 2 pipe/Direct vent furnace except the 140 size which can be installed as 2-pipe only. This provides added flexibility to meet diverse installation needs.

Adjustable Blower Speed —For precise

airflow selection of heating or cooling operation.

Casing —One piece, seamless wrap-

around construction of prepainted

galvanized steel resists corrosion.

Combustion Products Venting —The

combustion-air and vent pipes can terminate through a side wall or through the roof when used with a factoryauthorized vent termination kit.

Insulation —Foil-faced insulation in

heat exchanger section of the casing minimizes heat loss.

Certifications —The 58MCB units are

CSA (A.G.A. and C.G.A.) design certified for use with natural and propane gases. The furnace is factory-shipped for use with natural gas. 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 58MCB meets California Air Quality Management District emission requirements. Except for the 140 size unit, all sizes of the 58MCB can be installed in a manufactured (mobile) home when the optional kit is used. Refer to Vent Table for elevation limitations.

Quality Registration —The 58MCB is

engineered and manufactured under an ISO 9001 registered quality system.

NOTES:

1. The 58MCB Furnaces are for use with natural gas, but can be field-converted for propane gas with a factoryauthorized and listed accessory conversion kit.

2. Component location and configuration may be different than shown above.

Burner sight glass for viewing burner flame.

Burner assembly (inside) operates with energy-

saving, inshot burners and hot surface igniter for safe, dependable heating.

Redundant gas valve. Safe, efficient, gas control.

unction box for 115-v electrical power supply.

Vent outlet uses sealed PVC pipe to carry vent

gases from the furnace’s combustion system (right or left side).

Secondary condensing heat exchanger (inside), wrings out more heat through condensation of gases. Constructed with Polypropylene-laminated steel to ensure durability.

Pressure switch ensures adequate flow of flue products through furnace and out vent system.

CONCENTRIC VENT

(Direct Vent/2-Pipe

Application)

A concentric vent kit allows vent and combustion-air pipes to terminate through a single exit in a roof or side wall.

One pipe runs inside the other allowing venting through the inner pipe and combustion air to be drawn in through the outer pipe.

DOWNFLOW

SUBBASE

One base fits all furnace sizes. The base is designed to be installed between the furnace and a combustible floor when no coil box is used or when a coil box other than a Carrier cased coil is used. It is CSA (A.G.A./C.G.A.) design certified for use with Carrier 58MCB furnaces when installed in downflow

ELECTRONIC AIR

HUMIDIFIER

CLEANER

Cleans the air of smoke, dirt, and many pollens commonly found. Saves decorating and cleaning expenses by keeping carpets, furniture, and drapes cleaner.

By adding moisture to winterdry air, a Carrier humidifier can often improve comfort and keeps woodwork, wallpaper, and paint in better condition. Moisturizing household air also helps to retain normal body heat and provides comfort at lower temperatures.

AND ZONING

Available in programmable and non-programmable models, Carrier thermostats maintain a constant, comfortable temperature level in the home.

For the ultimate in home comfort, Carrier’s 2-zone, 4-zone and 8-zone systems allow temperature control of individual “zones” of the home. This is accomplished through a series of electronic dampers and remote room sensors. The 4-zone system is shown.

Disk usage. Unless otherwise specified, use perforated disk assembly (factory-supplied in loose parts bag). If one disk is stated, separate 2 halves of perforated disk assembly and use shouldered disk half. When using shouldered disk half, install screen side toward inlet box. †Wide radius elbow. ‡Vent sizing for Canadian installations over 4500 ft (1370 m) above sea level are subject to acceptance by the local authorities having jurisdiction. NA-Not Allowed; pressure switch will not make.

NOTES:

1. Do not use pipe size greater than those specified in table or incomplete combustion, flame disturbance, or flame sense lockout may occur.

2. Size both the combustion-air and vent pipe independently, then use the larger diameter for both pipes.

3. Assume two 45° elbows equal one 90° elbow. Long radius elbows are desirable and may be required in some cases.

4. Elbows and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.

5. The minimum pipe length is 5 ft for all applications.

6. Use 3-in. diameter vent termination kit for installations requiring 4-in diameter pipe.
