G61MP Gas Furnace

The G61MP category IV gas furnace is shipped ready for installation in the upflow, downflow, horizontal left air dis- charge or horizontal right air discharge position. The fur- nace is shipped with the bottom panel in place. The bot- tom panel must be removed if the unit is to be installed in upflow applications with bottom return air. The bottom panel must also be removed and discarded in all downflow or horizontal applications.

The furnace is equipped for installation in natural gas ap- plications. A conversion kit (ordered separately) is re- quired for use in propane/LP gas applications.

The G61MP can be installed as either a Direct Vent or a Non−Direct Vent gas central furnace.

NOTE − In Direct Vent installations, combustion air is taken from outdoors and flue gases are discharged outdoors. In Non−Direct Vent installations, combustion air is taken from indoors and flue gases are discharged outdoors. See figure 2 for applications involving roof termination.

This rating indicates that these units convert a significant portion of the fuel they consume into usable heat, resulting in lower energy bills for homeowners. The units are equipped with a modulating gas valve that further optimizes fuel usage by adjusting the gas flow according to the heating needs of the home.

Safety is a paramount consideration in the design of the G61MP Series. These units are built with advanced safety features, including a self-diagnostic control system that continuously monitors the unit’s performance. This system alerts homeowners to any potential issues, allowing for proactive maintenance and ensuring the longevity of the equipment.

The G61MP Series is also designed for ease of installation and servicing. Its compact design allows for flexible placement in various home environments, while the user-friendly access panels simplify routine maintenance tasks.

In conclusion, Lennox International Inc.'s G61MP Series Gas Units deliver a combination of advanced technology, energy efficiency, and reliability, making them an excellent choice for homeowners looking to enhance their heating systems.
