†A vent shall not terminate directly above a sidewalk or paved driveway that is located between two single family dwellings and serves both dwellings. †† 12 inches (30 cm) up from the bottom edge of the structure for Two-pipe (direct vent) applications per ANSI Z223.1 / NFPA 54, National Gas Code.

‡ Permitted only if veranda, porch, deck, or balcony is fully open on a minimum of two sides beneath the floor and the distance between the top of the vent termina- tion and the underside of the veranda, porch, or deck is greater than 1 foot (30 cm) as specified in CSA B149.1-00.

A vent shall not terminate less than 1 foot (30 cm) above a grade level.

Any fresh air or make up inlet for dryer or furnace area is considered to be forced air inlet.

Avoid areas where condensate drippage may cause problems such as above planters, patios, or adjacent to windows where steam may cause fogging.

A terminus of a vent shall be fitted with a cap in accordance with the vent manufacturer’s installation instructions, or in accordance with the installation instructions for a special venting system.

Responsibility for the provision of proper adequate venting and air supply for application shall rest with the installer.

Vent shall extend high enough above building, or a neighboring obstruction, so that wind from any direction will not create a positive pressure in the vicinity of the vent.

Consideration must be given for degradation of building materials by flue gases. Sidewall termination may require sealing or shielding of building surfaces with a corro- sion resistant material to protect against combustion product corrosion. Consideration must be given to wind direction in order to prevent flue products and/or conden- sate from being blown against the building surfaces. If a metal shield is used it must be a stainless steel material at a minimum dimension of 20 inches. It is recommended that a retaining type collar be used that is attached to the building surface to prevent movement of the vent pipe.

TG9S*MP, GG9S*MP specifications

Johnson Controls has long been at the forefront of building efficiency solutions, and their TG9S*MP and GG9S*MP series exemplify this commitment. These two-stage, multi-position gas furnaces are designed for optimal comfort and performance in residential applications, and they come packed with a variety of features that enhance their efficiency and operational capabilities.

One of the standout features of the TG9S*MP and GG9S*MP furnaces is their efficient two-stage operation. This technology allows the unit to operate at a lower capacity most of the time, which translates into reduced energy consumption and costs. When the demand for heating increases, the furnace automatically shifts to a higher capacity, ensuring a consistent and comfortable indoor temperature. This flexibility not only enhances comfort but also extends the lifespan of the unit as it doesn't have to work harder than necessary.

Energy efficiency is a crucial characteristic of both models. With an Annual Fuel Utilization Efficiency (AFUE) rating of up to 96%, these furnaces convert a significant amount of the fuel they consume into usable heat. Such efficiency ratings not only help in reducing energy bills but also have a positive impact on the environment by minimizing greenhouse gas emissions.

Both models feature advanced technology in their design, including a fully modulating gas valve and a variable-speed blower motor. The modulating valve adjusts the gas flow in response to the thermostat’s signals, allowing for precise temperature control and improved comfort. Meanwhile, the variable-speed blower motor enhances airflow while operating quietly, significantly improving overall indoor air quality by promoting even heat distribution throughout the home.

From a structural standpoint, the TG9S*MP and GG9S*MP are built with durable materials designed for longevity. Their compact design allows for flexible installation options, whether in a closet, attic, or basement. The furnaces also come equipped with a robust heat exchanger crafted from high-quality materials, which ensures both reliability and efficiency.

In conclusion, the Johnson Controls TG9S*MP and GG9S*MP furnaces provide homeowners with efficient, reliable, and comfortable heating solutions. With advanced features such as two-stage operation, impressive AFUE ratings, and modern technology integrations, these models stand out in the market as dependable options for both energy savings and year-round comfort. Whether you're a homeowner looking to upgrade your heating system or a contractor seeking high-quality products for your clients, these furnaces represent a smart choice.
