PRODUCT DESIGN

quired due to the natural reduction in the density of both the gas fuel and combustion air as altitude increases. The kit will provide the proper design certified input rate within the specified altitude range.

High altitude kits are purchased according to the installa- tion altitude and usage of either natural or propane gas. Refer to the chart above for a tabular listing of appropriate altitude ranges and corresponding manufacturer’s high altitude Natu- ral Gas and Propane Gas kits. For a tabular listing of appro- priate altitude ranges and corresponding manufacturer's High Altitude Pressure Switch kits, refer to either the Pressure Switch Trip Points & Usage Chart in this manual or the Ac- cessory Charts in Service Instructions.

of time before stepping up to high stage to satisfy the thermostat’s call for heat. The delay period prior to stepping up can be set at either a fixed 5 minute time delay or a load based variable time between 1 and 12 minutes (AUTO mode). If the AUTOmode is selected, the control averages the cycle times of the previous three cycles and uses the average to determine the time to transition from low stage to high stage.

To use a single-stage thermostat, turn off power to the fur- nace, move the thermostat selection DIP switch to the OFF position. Set the desired transition time by setting the tran- sition delay DIP switch to the desired ON/OFF position. Turn power back on. Refer to the following figure.

Single Stage Thermostat

A single-stage thermostat with only one heating stage may be used to control this furnace. The application of a single- stage thermostat does not offer “true” thermostat-driven two- stage operation, but provides a timed transition from low to high fire. The furnace will run on low stage for a fixed period

Goodman 90%-95% Gas Furnace Units, ACVC9/AMVC95, GCVC9/GMVC95 specifications

Goodman Manufacturing is a prominent name in the HVAC industry, known for providing energy-efficient solutions that cater to both residential and commercial environments. Among its offerings, the Goodman GCVC9/GMVC95 and ACVC9/AMVC95 models stand out as top-tier gas furnace units, with efficiency ratings between 90% and 95%. These furnaces provide an excellent balance of performance, reliability, and affordability.

The GCVC9 and GMVC95 gas furnace units are designed with advanced features that ensure optimal heating and comfort. One of the key characteristics of these models is their energy efficiency. With Annual Fuel Utilization Efficiency (AFUE) ratings of up to 95%, these furnaces convert nearly all the fuel they consume into heat, resulting in significant cost savings on energy bills. This makes them an ideal choice for homeowners looking to reduce their carbon footprint while maintaining a comfortable indoor environment.

These units are equipped with a two-stage gas valve and a variable-speed blower motor. The two-stage gas valve allows for precise temperature control by providing two levels of heating output, ensuring that the furnace runs at lower capacities during milder conditions and ramping up when more heat is needed. The variable-speed blower motor enhances comfort by providing consistent airflow, reducing temperature fluctuations, and operating more quietly than single-speed motors.

Another notable feature is the firing system, which utilizes a hot surface igniter for reliable operation. This technology enhances safety and performance, eliminating the need for a pilot light and minimizing gas waste. Additionally, both models are designed for easy installation and maintenance, with features like a compact design and convenient access to internal components.

Durability is also a hallmark of Goodman furnaces. The units are constructed with high-quality materials, including a heavy-gauge steel cabinet and a durable powder-coated finish to resist corrosion. Furthermore, Goodman offers exceptional warranties, including a lifetime heat exchanger warranty, providing peace of mind for homeowners.

In conclusion, the Goodman GCVC9/GMVC95 and ACVC9/AMVC95 gas furnace units are engineered for efficient heating with advanced technologies that enhance performance and comfort. Their high AFUE ratings, reliable ignition system, and durable construction make them excellent choices for anyone looking to invest in a reliable heating solution. With Goodman at the helm, homeowners can enjoy efficient heating without compromising on comfort or cost.
