NOTE − Do not discharge exhaust gases directly into any chimney or vent stack. If ver- tical discharge through an existing unused chimney or stack is required, insert piping inside chimney until the pipe open end is above top of chimney and terminate as illus- trated. In any exterior portion of chimney, the exhaust vent must be insulated.

Details of Exhaust Piping Terminations for Non-Direct Vent Applications

Exhaust pipes may be routed either horizontally through an outside wall or vertically through the roof. In attic or closet installations, vertical termination through the roof is pre- ferred. Figures 40 through 43 show typical terminations.

1 − Exhaust piping must terminate straight out or up as shown. The termination pipe must be sized as listed in table 8.The specified pipe size ensures proper veloc- ity required to move the exhaust gases away from the building.

2 − On field supplied terminations for side wall exits, ex- haust piping should extend a maximum of 12 inches (305mm) beyond the outside wall, unless support is provided in the horizontal section. See figure 41.

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.
