77,000 BTU

BTU, or British Thermal Unit, ratings are a standard way to describe and compare furnace capacity. The Guardian DGAX077BDTA has a 77,000 BTU input rating and a 62,000 BTU output rating. Compare these figures with the heating requirements of the home.

80% AFUE

AFUE, or Annual Fuel Utilization Efficiency, measures how much of the fuel energy a furnace turns into usable heat over a typical year. A higher number indicates greater efficiency. This furnace carries an 80% AFUE rating.

Sealed Combustion

The sealed combustion design draws combustion air directly from outside the home. This supports quiet operation and helps reduce cold drafts. The furnace vents through a manufactured home roof jack, so confirm the correct roof jack for the installation.

Downflow Design

This furnace is a downflow unit, delivering heated or cooled air downward into floor ductwork, the typical layout in manufactured homes. Its zero clearance design lets it be installed in a closet or alcove where space is limited.

Two Systems in One

The DGAX Series works as both a gas furnace and an air handler. The built-in coil cabinet accepts a matching indoor coil, and the standard ECM blower is ready for air conditioning up to 4 tons. An optional blower accessory is available for 5 ton cooling applications.

Single Stage Heating

Single-stage, or 1-stage, furnaces run at one fixed heat output level. The furnace turns on at full output when heat is needed and shuts off once the thermostat setting is reached.

Durable Construction

An aluminized steel heat exchanger provides efficient operation and corrosion resistance, and the louvered front door panels are built for durability. Electronic hot surface ignition helps save fuel costs while increasing dependability.

Cabinet Dimensions

The cabinet is listed at 19.5 inches wide, 76 inches high, and 24.75 inches deep. Use these measurements to plan for placement, access, and clearances.

Before ordering, verify the model number, 77,000 BTU input, 80% AFUE rating, downflow configuration, cooling capacity, roof jack requirements, and cabinet dimensions against your project requirements.
