Horizontal Applications

The G61MP furnace can be installed in horizontal applica- tions with either right− or left−hand air discharge.

The G61MP may also be installed as a unit heater. Either suspend the furnace as shown in figure 18, or install the furnace on a field−fabricated raised platform. The unit must be supported at both ends and beneath the blower deck to prevent sagging.

Refer to figure 17 for clearances in horizontal applications.

*Front clearance in alcove installation must be 24 in. (610 mm). Maintain a minimum of 24 in. (610 mm) for front service access. **A 5−1/2ained below the unit to

provide for servicing of the condensate trap.

‡For installations on a combustible floor, do not install the furnace directly on carpeting, tile or other combustible materials other than wood flooring.

Suspended Installation of Horizontal Unit

NOTE − If unit is suspended in attic or crawl space, horizon- tal support kit (Cat No. 56J18 ordered separately) must be used to ensure proper unit support and coil drainage.

1 − Select location for unit keeping in mind service and other necessary clearances. See figure 17.

2 − Provide service platform in front of unit.

3 − If unit is installed above finished space, fabricate a drain pan fitted with a 1/2 inch or 3/4 inch N.P.T. fitting.

4 − Using 3/8 inch rods and support frame kit or field−fabri- cated supports, fabricate suspension hangers, keep- ing in mind front service access clearances.

5 − Mount unit on support frame as shown in figure 18.

6 − Continue with exhaust, condensate and intake line piping instructions.

7 − If unit is suspended above finished space, hang the field−provided drain pan below the support frame as shown in figure 18. Leave 5−1/2 inches for service clearance below unit for condensate trap.

8 − Route auxiliary drain line so that water draining from this outlet will be easily noticed by the homeowner. If necessary, run the condensate line into a condensate pump to meet drain line slope requirements. The pump must be rated for use with condensing furnaces. Protect the condensate discharge line from the pump to the outside to avoid freezing.

1 − Select location for unit keeping in mind service and other necessary clearances. See figure 17.

2 − Construct a raised wooden frame and cover frame with a plywood sheet. Provide a service platform in front of unit. If unit is installed above finished space, fabricate a drain pan to be installed under unit.

When installing the unit in a crawl space, a proper sup- port platform may be created using cement blocks and the horizontal support frame kit (ordered separately,

G61MP Series Units, Gas Units specifications

Lennox International Inc. has established itself as a leader in the heating and cooling industry, and its G61MP Series Gas Units stand as a testament to the company's commitment to innovation and energy efficiency. These gas units are specifically designed for residential applications and are recognized for their reliability, performance, and advanced technology.

One of the main features of the G61MP Series is its variable speed motor, which offers significantly enhanced comfort over traditional single-stage gas units. This technology allows for precise temperature control and improved humidity management. By adjusting its speed according to the heating demand, the unit minimizes temperature fluctuations, leading to a more consistent indoor climate.

Another notable characteristic of the G61MP Series is its ECM blower motor, which operates quietly and efficiently. This motor not only reduces energy consumption but also enhances the overall comfort of the home by providing a steady flow of warm air without the disruptive noise often associated with traditional gas units.

The G61MP Series units are designed with a focus on energy efficiency, boasting an impressive Annual Fuel Utilization Efficiency (AFUE) rating. 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. With features designed to maximize comfort, minimize energy costs, and ensure safety, these units represent a significant advancement in residential heating solutions.
