Let's Get Started!
Hey friends, Mark here! If you’ve got your eyes on the Goodman GR9S920603BN furnace (check it out here), you’re about to make your home a warm, energy-efficient haven.
This little powerhouse packs 60,000 BTUs, a 92% AFUE rating, and a 9-speed ECM blower in a compact 17.5-inch cabinet. But like all serious heating machines, proper installation is everything. Follow along as I break it down step by step—with my personal tips sprinkled in so you don’t hit any surprises. 🔧🔥
Step 1: Gather Your Tools and Prepare the Space
Before touching the furnace, make sure you have:
-
Screwdrivers (Phillips & flathead)
-
Wrenches & pliers
-
Drill with bits
-
Level and tape measure
-
Combustion analyzer (optional, but recommended for pros)
Clear the installation area. Whether you’re going upflow in the basement or horizontal in a crawl space, make sure there’s room to maneuver and proper ventilation.
For safety, always shut off power and gas lines before starting—trust me, you don’t want surprises here. For general safety guidance on furnace installation, this guide from the U.S. Department of Energy is worth a look.
Step 2: Unbox and Inspect Your Furnace
Check the contents:
-
GR9S920603BN furnace unit
-
Installation manual & warranty card
-
Mounting hardware and drain kit
Look for shipping damage. Make sure panels, burners, and blower assembly are intact. Any missing or damaged parts can slow you down or cause issues later.
Step 3: Positioning the Furnace
This furnace supports upflow and horizontal configurations:
-
Upflow: Ideal for basements or utility rooms. Ensure clearance around the unit for airflow and maintenance.
-
Horizontal: Great for attics or crawl spaces. Make sure the furnace is level to avoid drainage problems.

Step 4: Venting and Combustion Air
Proper venting is critical for safety and efficiency. The GR9S920603BN allows both direct vent and non-direct vent installations. Follow the manufacturer’s specifications for pipe diameter, termination points, and clearances.
-
Use rigid or approved PVC venting for the most secure installation.
-
Maintain minimum clearance from combustibles.
More details on furnace venting can be found in Goodman’s official installation manual.
Step 5: Gas and Electrical Connections
-
Gas: Only a licensed professional should connect the gas line. Test for leaks with a soapy water solution before firing the furnace.
-
Electrical: Connect to a 115V supply. Ensure proper grounding and secure connections.

Step 6: Ductwork and Airflow
The GR9S920603BN has a 9-speed ECM blower capable of moving ~1200 CFM. Ensure your ducts are sized appropriately to match airflow requirements:
-
Measure existing ducts and adjust if needed
-
Seal all joints to prevent leaks
-
Insulate ducts in unconditioned spaces to maintain efficiency
Check out Energy Star’s HVAC duct guide for tips on proper ductwork sizing and sealing.
Step 7: Startup and Initial Testing
-
Turn on power and gas supply
-
Set thermostat to heating mode
-
Observe ignition sequence
-
Confirm proper flame and burner operation
-
Use a combustion analyzer if available to check gas pressure
If something seems off—like delayed ignition or inconsistent airflow—double-check venting, filters, and electrical connections.
Step 8: Final Adjustments and Tips
-
Install the access panels securely
-
Check that condensate lines are flowing freely
-
Test the blower at different speeds for smooth operation
Pro tip: Label wires and document your setup.
