VENT SYSTEM

This furnace is certified to be installed with one of two possible vent configurations.

1.Horizontal vent system. This vent system can be installed com- pletely horizontal or combinations of horizontal, vertical, or offset using elbows.

2.Vertical vent system. This vent system can be installed completely vertical or a combination of horizontal, vertical, or offset using elbows.

VENT APPLICATIONS AND TERMINATION

When selecting the location for a combustion air / vent termination, the following should be considered:

1.

Observe all clearances listed in vent clearances in these instruc-

 

tions.

2.

Termination should be positioned where vent vapors will not dam-

12” MIN.

12” MIN.

12” Minimum below overhang

12” Minimum separation between bottom of combustion air intake and bottom of vent

Maintain 12” minimumclearance above highest anticipated snow level or grade, whichever is higher

 

age plants or shrubs or air conditioning equipment.

3.

Termination should be located where it will not be affected by wind

 

gusts, light snow, airborne leaves or allow recirculation of flue

 

gases.

4.

Termination should be located where it will not be damaged or

 

exposed to flying stones, balls, etc.

5.

Termination should be positioned where vent vapors are not objec-

 

tionable.

6.

Horizontal portions of the vent system must slope upwards and be

 

supported to prevent sagging.

7.

Direct vent systems must be installed so the vent and the combus-

 

tion air pipes terminate in the same atmospheric zone. Refer to Fig-

 

ures 31 or 32.

Maintain 12” minimum clearance above highest anticipated snow level. Maximum 24” above roof.

VENTING MULTIPLE UNITS

Multiple units can be installed in a space or structure as either a single pipe configuration or a two-pipe configuration.

The combustion air side of the single pipe configuration shown in Figure 30 is referred to in these instructions as ambient combustion air supply. Follow the instructions for ambient combustion air installations, paying particular attention to the section on air source from inside the building. The vent for a single pipe system must be installed as specified in the venting section of these instructions with the vent terminating as shown in Figure 30. Each furnace must have a separate vent pipe. Under NO circumstances can the two vent pipes be tied together.

The combustion air side of the two-pipe configuration shown in Figure 31 can be installed so the combustion air pipe terminates as described in outdoor combustion air or ventilated combustion air sections in these instructions. Follow the instructions for outdoor combustion air or venti- lated combustion air and the instructions for installing the vent system with the vent terminating as shown in Figures 33 or 34. The two-pipe system must have a separate combustion air pipe and a separate vent pipe for each furnace. Under NO circumstances can the two combus- tion air or vent pipes be tied together. The combustion air and vent pipes must terminate in the same atmospheric zone.

This not only enhances comfort by maintaining consistent temperatures but also significantly reduces energy consumption. The variable speed motor operates quietly and efficiently, making it ideal for both living environments and workplaces.

In terms of design, the TM9V*MP is engineered for ease of installation and maintenance. It comes in a compact size that allows for flexible positioning within existing ductwork, making retrofits simpler for contractors. Additionally, the modular design allows for easy access to internal components, which facilitates hassle-free servicing and maintenance.

The unit also features a robust filtration system that works in tandem with a range of air quality technologies. This includes optional media filters that capture allergens and particulates, ensuring that the air quality within a space is not only comfortable but also healthy. The integration of advanced technologies, such as integrated Wi-Fi capabilities, provides users with the ability to monitor and adjust settings remotely via smartphones or tablets.

Moreover, the TM9V*MP series is compatible with a wide range of communication protocols, enabling seamless connectivity with smart home systems. This means that users can create customized comfort profiles and take advantage of energy-saving features automatically.

Durability is another key characteristic of the TM9V*MP series. Built with high-quality materials and subjected to rigorous testing, these air handlers are designed to endure even the most demanding conditions while providing reliable performance over time.

In summary, Johnson Controls' TM9V*MP series offers an array of features that cater to modern comfort demands. With its variable speed technology, user-friendly design, air quality enhancements, and strong connectivity options, it stands out as a prime choice for both residential and commercial HVAC applications, setting a high standard for efficiency and indoor comfort.
