To maximize heat exchanger life, the combustion air must be free of chemicals which form corrosive acidic compounds in the combustion gases. Some examples of these chemicals are chlorine, fluorine, and sulphur. Some common sources of these chemicals are detergents, bleaches, aerosol sprays, cleaning solvents, and a wide variety of commercial and household products.

be connected to any other heat producing device such as a fireplace insert, stove, etc. Doing so may result in fire, explosion, personal injury, carbon monoxide poisoning, or property damage.

Use a type high velocity air filter in the return air duct to maintain a clean heat exchanger.

3. Return Air Supply

In applications where the supply ducts carry heated air to areas outside the space in which the furnace is installed, the return air must be delivered to the furnace by duct(s) sealed to the furnace casing. These duct(s) must be full size and without interruption in the spaces outside of where the furnace is installed.

The return air duct connection(s) must be physically sound and sealed to the furnace casing to prevent products of combustion from entering the living space.

The floor or platform on which the furnace is mounted must provide sound physical support of the furnace with no gaps, cracks, or sagging between the furnace and floor or platform. The return air and circulating air ductwork must not

!WARNING:

Failure to prevent products of com- bustion from being circulated into the living space can create potentially hazardous conditions including car- bon monoxide poisoning that could result in personal injury or death.

4. Vent System

The furnace must always be connected to an approved vent pipe to carry the furnace combustion products outdoors. At the beginning and end of each heating season, inspect the outdoor vent terminal closely with a flashlight to determine if any of the conditions listed under the following warning exist.

Residential Gas Furnaces specifications

Nordyne Residential Gas Furnaces are a prominent choice for homeowners seeking reliable heating solutions. Renowned for their efficiency and durability, these furnaces are designed to meet the demands of various climates while ensuring optimal home comfort.

One of the primary features of Nordyne gas furnaces is their high-efficiency ratings. Many models boast AFUE (Annual Fuel Utilization Efficiency) ratings of 90% or higher, which means they convert a significant percentage of gas into usable heat. This efficiency translates to lower energy bills and a reduced environmental footprint. The advanced heat exchangers used in these furnaces allow for efficient heat transfer and improved performance.

Nordyne also incorporates multi-stage heating technology in their gas furnaces. This feature enables the system to adjust its heating output based on the current demand, promoting energy savings and creating a more consistent indoor temperature. The quiet operation of these units ensures that comfort doesn’t come at the expense of noise, making for a peaceful home environment.

Another standout technology in Nordyne gas furnaces is the use of modulating gas valves. These valves control the amount of gas supplied to the burner, allowing the system to operate at varying speeds. Consequently, this results in more precise temperature control and enhanced energy efficiency, as the furnace can run longer at lower capacities instead of cycling on and off frequently.

Durability is a hallmark of Nordyne products. The furnaces are constructed with high-quality materials that resist wear and tear over time, providing reliability that homeowners can depend on during the cold months. Many models also feature a robust warranty, offering peace of mind regarding long-term performance.

Nordyne's commitment to innovation extends to their intelligent controls and smart technology compatibility. Many models can be integrated with home automation systems, allowing users to monitor and adjust their heating remotely. This connectivity enhances convenience and energy management.

In addition, Nordyne gas furnaces are designed with easy maintenance in mind. Features like accessible filter locations and diagnostic controls simplify routine upkeep, contributing to the longevity of the unit.

In conclusion, Nordyne Residential Gas Furnaces stand out for their energy efficiency, advanced technologies, durability, and user-friendly features. Homeowners can feel confident investing in these heating solutions, knowing they prioritize comfort, performance, and cost-efficiency.
