Intertherm 4 Ton AC And 95% AFUE Downflow Gas Furnace System with Coil Cabinet for Mobile Homes - Top-Return, Select Your Furnace, R454B

High-Efficiency Gas Comfort with Flexible Return-Air Options

Up to 95% AFUE heating designed for the specialized layouts of factory-built homes.

The Intertherm MG2R Series Gas Furnace combines high-efficiency single-stage heating with configuration choices for compatible manufactured and mobile homes. Models are available with front-return or top-return airflow and with or without a coil cabinet, allowing the furnace to match different replacement and central-cooling layouts.

MG2R furnaces provide up to 95% AFUE with nominal input capacities from 45,000 to 72,000 BTU. A multi-speed ECM blower supports compatible heating and cooling airflow requirements, while the direct-vent design allows approved vertical or horizontal two-pipe venting installations.

• Up to 95% AFUE: Uses a high percentage of the supplied fuel for home heating.
• Single-Stage Operation: Provides consistent heating output during each operating cycle.
• Front- or Top-Return Options: Allows selection based on the home’s return-air layout.
• With or Without Coil Cabinet: Supports different cooling-coil and installation-height requirements.
• Multi-Speed ECM Blower: Provides selectable airflow for approved heating and cooling applications.
• Category IV Direct Venting: Supports approved vertical or horizontal two-pipe configurations.
• Propane Conversion Capability: Conversion must follow the manufacturer’s instructions.
• Diagnostic Indicators: Help qualified technicians identify operating and service conditions.

The Intertherm MG2R Series was formerly marketed under the Revolv brand. Select the furnace according to the home’s heating load, return-air position, coil-cabinet requirement, fuel supply and approved cooling-system combination.

Simplify the Outdoor Termination for a Direct-Vent Gas Furnace

A compact termination assembly routes combustion air and furnace exhaust through one coordinated opening.

Intertherm Concentric Vent Kits provide an approved termination option for specific high-efficiency gas furnaces. A concentric assembly keeps the combustion-air intake and exhaust pathways separate while arranging them within one coordinated termination, reducing the number of exterior wall or roof openings required.

Two kit sizes are available, but they are not universally interchangeable. Model 904952 uses a 2-inch connection and is listed for compatible MG2R and MG3P furnaces. Model 904953 uses a 3-inch connection and is listed for compatible MG2R, MG2S and MG3P furnaces. Final sizing depends on the furnace model, vent length, number of fittings and installation requirements.

• Concentric Configuration: Coordinates separate combustion-air and exhaust pathways at one termination.
• Reduced Exterior Openings: Can simplify the finished wall or roof penetration.
• Two Available Sizes: Choose between the applicable 2-inch and 3-inch models.
• Model-Specific Compatibility: Furnace compatibility differs between 904952 and 904953.
• Direct-Vent Application: Intended for qualifying high-efficiency gas-furnace installations.
• Professional Sizing Required: Vent diameter and installation limits must follow the furnace instructions.

These Intertherm venting accessories were formerly marketed under the Revolv brand. Do not select a kit by pipe diameter alone; verify the exact furnace model and complete venting requirements before ordering.

High-Capacity Indoor Cooling Designed for Factory-Built Homes

Efficient 4-ton heat transfer supports dependable cooling in properly matched air-conditioning systems.

The Intertherm C85DAMX48U-B is a 4-ton, 48,000 BTU uncased indoor evaporator coil developed for compatible manufactured and modular home air-conditioning systems. This model is intended for cooling-only applications and works with an approved outdoor air conditioner and compatible indoor furnace.

For homeowners familiar with the former Revolv equipment line, Intertherm now carries that manufactured-home HVAC tradition forward. Its micro-channel A-coil design efficiently transfers indoor heat to the R454B refrigerant, while the factory-installed TXV regulates refrigerant flow to support consistent cooling performance.

• 4-ton cooling capacity: Supports approved air-conditioning systems with approximately 48,000 BTUs of nominal capacity.
• Cooling-only design: Intended for compatible air-conditioner combinations rather than heat-pump applications.
• R454B compatibility: Engineered for current R454B split-system equipment.
• Micro-channel construction: Supports efficient heat transfer through a compact indoor coil design.
• Factory-installed TXV: Adjusts refrigerant flow to help maintain proper system performance.
• Vertical A-coil configuration: Designed for compatible manufactured-home furnace and airflow arrangements.
• Uncased installation: Fits inside an approved furnace or coil cabinet without an additional outer casing.

The C85DAMX48U-B provides the indoor heat-transfer component needed for an approved 4-ton Intertherm cooling system. Because this model is designed for air-conditioning applications, a qualified HVAC professional should verify the outdoor condenser, furnace, airflow, and certified coil match before purchase.
