Devices attached to the flue or vent for the purpose of reducing heat loss up the chim- ney have not been tested and have not been included in the design certification of this furnace. We, the manufacturer, can not and will not be responsible for injury

1. Safety Information

The furnace area and the vicinity of any other gas appliance must be kept clear and free of combustible materials, gasoline, and other flammable vapors and liquids. Do not store or use flammable items such as paint, varnish, or strippers in the vicinity of the furnace.

Do not use the furnace closet or area next to the furnace as a storage area. This area must be kept clear, clean, and free of lint. The furnace must also be kept clear of loose or exposed insulation materials. Examine the furnace area when the furnace is installed or when insulation is added. Some insulation materials may be combustible.

For proper and safe operation, the furnace needs air for combustion and ventilation. Do not block or obstruct air openings on the furnace, or any air openings where the furnace may be installed, including any surrounding spaces.

Should the gas supply fail to shut off or if overheating occurs, shut off gas valve to the furnace before shutting off electrical supply.

Do not use this furnace if any part has been

under water. A flood-damaged furnace is extremely dangerous. Attemps to use the furnace can result in fire or explosion. A qualified service agency should be contacted to inspect the furnace and to replace all gas controls, control system parts, electrical parts that have been wet or the furnace if deemed necessary.

Familiarize yourself with the controls that shut off the gas and electrical power to the furnace. If the furnace is to be shut down for an extended period of time, turn off both the gas and electrical power. For your safety always turn off both the gas and electrical power before performing service or maintenance on the furnace.

2. Combustion Air Supply

A furnace needs an adequate supply of combustion and ventilation air for proper and safe operation. Follow the installation instructions included with the furnace to properly vent air to the combustion air inlet and exhaust the products of combustion to the outside from the exhaust vent.

For 90+ and 93+ Models: If the furnace is operated with a restricted combustion air supply, the pressure switch will open, turning off the gas supply to the burners. (See Figures 2 and 3). DO NOT install a jumper wire across this switch to defeat its function. If this switch must be replaced, use only the replacement part specified in the Replacement Parts List.

For 80+ Models: If the furnace is operated with inadequate combustion air supply, the flame roll- out control switch located above the burners may open, turning off the gas supply to the burners. The flame roll-out control is a manually resettable device (See Figure 1 and 4). DO NOT install a jumper wire across this switch to defeat its function. DO NOT reset the control without identifying and correcting the fault condition which caused the control to trip. If this switch must be replaced, use only the replacement part specified in the Replacement Parts List.

Air openings in warm air registers, and return air grilles must not be restricted.

!CAUTION:

Combustion air must not be drawn from a corrosive atmosphere.

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.
