VENT/FLUE PIPE & COMBUSTION AIR PIPE

In a basement installation, the vent/flue pipe can be run between joist spaces. If the vent pipe must go below a joist and then up into the last joist space to penetrate the header, two 45° elbows should be used to reach the header rather than two 90° elbows.

DIRECTVENT(DUALPIPE)PIPING

The inlet air screens provided in the installation instruction packet are available for the installer to use in the inlet of the combustion air pipe to prevent animals from building nests in the combustion air pipe. Installation of screens, while strongly recommended, is not required and will not affect performance of the unit.

Direct vent installations require both a combustion air intake and a vent/flue pipe. The pipes may be run horizontally and exit through the side of the building or run vertically and exit through the roof of the building. The pipes may be run through an existing unused chimney; however, they must extend a minimum of 12 inches above the top of the chimney. The space between the pipes and the chimney must be closed with a weather tight, corrosion resis- tant flashing. Both the combustion air intake and a vent/flue pipe terminations must be in the same atmospheric pressure zone. Refer to Vent/Flue and Combustion Air Pipe - Termination Loca- tions or Concentric Vent Termination for specific details on termi- nation construction. For details concerning connection of pipes to the furnace, refer to the Vent/Flue Pipe and Combustion Pipe - Standard Furnace Connections or Alternate Furnace Connections.

Refer to the following table for applicable length, elbows, and pipe diameter for construction of the vent/flue and combustion air intake pipe systems of a direct vent (dual pipe) installation. The number of elbows tabulated represents the number of elbows and/or tees in each (Vent/Flue & CombustionAir Intake) pipe. Elbows and/or tees used in the terminations must be included when determining the number of elbows in the piping systems.

If the combustion air intake pipe is to be installed above a finished ceiling or other area where dripping of condensate will be objec- tionable, insulation of the combustion air pipe may be required. Use 1/2” thick closed cell foam insulation such as Armaflex™ or Insultube™ where required.

VENT/FLUE AND COMBUSTION AIR PIPE TERMINATIONS

The vent/flue and combustion air pipes may terminate vertically, as through a roof, or horizontally, as through an outside wall.

The ECM motor also operates quietly, enhancing the comfort of your living space without the disruptive noise often associated with traditional furnaces.

The MVC95, on the other hand, offers similar efficiency with its also 95% AFUE rating. This model is equipped with a patented ignition system that enhances reliability with minimal maintenance needs. Its durable construction includes a heavy-gauge steel cabinet and an insulated blower compartment that minimizes heat loss. This design not only supports optimal performance but also contributes to its longevity.

Both models come with a self-diagnostic control board that provides straightforward troubleshooting capabilities, making it easier for technicians to ensure that your system is operating at peak performance. This feature aids in timely maintenance, which is crucial for extending the lifespan of the unit.

Additionally, Goodman backs their products with a strong warranty, offering a lifetime limited warranty on the heat exchanger and a 10-year limited parts warranty. This assurance provides homeowners peace of mind regarding their investment.
