Hey folks, Mike here!
If you just picked up the Goodman GR9S920603BN furnace, congrats — you’ve got a solid, efficient system on your hands. This 60,000 BTU, 92% AFUE furnace with a 9-speed ECM blower is perfect for upflow or horizontal installations.
Installing a furnace can feel intimidating, but I’ll break it down step by step so even a hands-on homeowner can follow along. And remember, if something feels off, always call a professional — safety first! 💪
Step 1: Preparation
Before you touch a wrench or wire:
-
Gather all necessary tools: screwdrivers, wrenches, tape, level, and safety gear.
-
Turn off the power and gas supply in your home.
-
Clear the installation area and verify that it meets local codes.
For a more detailed preparation checklist, check HVAC.com’s furnace installation guide.
Step 2: Positioning the Furnace
-
Place the furnace on a level surface.
-
Ensure there’s proper clearance on all sides for airflow and maintenance.
-
If you’re doing a horizontal installation, make sure the airflow direction matches the manufacturer’s specifications.
Tip: A level furnace ensures proper condensate drainage and reduces stress on the blower motor.
Step 3: Connecting Ductwork
-
Secure supply and return ducts to the furnace.
-
Seal all joints with foil tape or mastic to prevent leaks.
-
Check that ducts are properly sized for the system’s airflow requirements.

Step 6: Venting
-
Install the venting according to local code.
-
Ensure the vent termination is clear of debris and obstructions.
-
Check that the vent system is correctly pitched to allow condensate drainage.
Proper venting ensures both safety and efficiency for high-AFUE furnaces.
Step 7: System Startup
-
Turn on gas and electricity.
-
Set the thermostat to the desired temperature.
-
Watch the furnace run through its first cycle to verify ignition, blower operation, and airflow.
Tips for a Smooth Installation
-
Always double-check clearances around the furnace.
-
Label wires and ducts to make future troubleshooting easier.
-
Make sure your air filter is installed before startup to prevent blower issues.
-
Keep the manual handy — the diagrams and specs are gold.
