Goodman 80,000 BTU Efficient Upflow Furnace GR9S800804BN

Description

Product Overview

The Goodman GR9S800804BN is a high‑performance furnace engineered for demanding laboratory and industrial environments. Rated at 80,000 BTU, it operates at 80% seasonal energy efficiency ratio (SEER), delivering powerful heating while reducing energy consumption. The unit features a multi‑speed ECM (electronically commutated motor) that intelligently adjusts airflow to match load conditions, resulting in quieter operation and finer temperature control. Constructed with an aluminized steel primary heat exchanger, the furnace ensures durability and resistance to corrosion, extending service life even under continuous use. Its compact cabinet dimensions—33.38″ × 28″ × 17.5″—allow for easy installation in upflow or horizontal configurations, making it suitable for tight spaces. The polished grey finish provides a professional appearance that blends seamlessly with most lab and industrial settings.

Usage

This furnace is designed for a variety of applications, including research laboratories, manufacturing facilities, and large‑scale HVAC systems that require reliable, high‑capacity heating. The upflow/horizontal installation flexibility means it can be mounted in ceiling voids, raised floors, or dedicated equipment rooms where space is at a premium. It excels in environments where precise temperature regulation is critical, such as chemical processing labs, pharmaceutical production areas, and testing chambers. The low‑noise ECM motor makes it suitable for settings where acoustic comfort is important, like clean rooms or office‑adjacent facilities. The unit is compatible with both natural gas and liquid propane (LP) conversion kits, allowing it to adapt to varying fuel availability across different regions.

FAQ

Can this furnace be installed as a downflow unit?

No. The GR9S800804BN is engineered for upflow or horizontal installation only. For downflow applications, Goodman offers separate model lines that begin with the GD9 prefix.

What type of fuel does the furnace support?

The unit is supplied for natural gas use. A liquid propane (LP) conversion kit is available separately, allowing the furnace to operate on propane where natural gas is not accessible.

How does the ECM motor improve efficiency?

The ECM motor adjusts its speed based on heating demand, delivering only the airflow needed at any given moment. This variable‑speed operation reduces energy waste, lowers operating noise, and extends motor life compared to traditional single‑speed fans.

What is included in the warranty?

The warranty covers parts for ten years when the furnace is installed by a certified technician and the unit is registered online within 60 days of installation. Labor is not covered, but Goodman provides optional service plans for extended coverage.

Is professional installation required?

Yes. To qualify for the warranty and ensure optimal performance, the furnace must be installed by a qualified HVAC professional familiar with upflow/horizontal configurations and local building codes.
