Tony’s Hello
Alright, furnace warriors—Tony here. You’ve got the Goodman GR9S960803BN staring at you and thinking, “Do I really have to wrestle this beast into place?” The answer: yes—but I’m here to make it painless. We’re covering step-by-step installation, both upflow and horizontal setups, with safety, efficiency, and a little Tony-style sarcasm thrown in.🔥
Section 1: Prep Like a Pro
Before you even touch that 80,000 BTU monster:
-
Safety first – shut off gas and power. Seriously. Don’t test your luck. (HVAC Optimizer’s Gas Furnace Guide)
-
Check the location – for upflow, ensure vertical clearance; for horizontal, check space for vents and condensate lines.
-
Tools & materials – level, wrenches, foil tape, pipe sealant, and a sturdy work surface.
-
Permits – your local code might require inspection. Don’t skip it.
Tip from Tony: measure twice, curse once. 😎
Section 2: Remove the Old Furnace
-
Disconnect gas line and power.
-
Label electrical wires—you’ll thank me later.
-
Remove duct connections carefully.
Section 3: Position the New GR9S960803BN
Upflow Installation:
-
Place the unit on a level platform.
-
Ensure bottom vents align with return ducts.
-
Leave clearance for the service panel and filter access.
Horizontal Installation:
-
Rotate the cabinet carefully.
-
Ensure vent and condensate connections remain accessible.
-
Double-check level to prevent condensate pooling.
Pro tip: If it’s a tight squeeze, get a buddy. This thing’s not light. 💪
Section 4: Connect Ductwork
-
Seal return and supply ducts with foil tape, not duct tape.
-
Check that there are no kinks or blockages.
-
Horizontal runs may need additional support brackets.

Section 5: Gas and Electrical Connections
-
Gas line: Apply pipe sealant and test for leaks. Safety first!
-
Electrical: Follow manufacturer’s wiring diagram. Labeling is critical.
-
Thermostat: Install or reconnect, ensuring proper C-wire connections.

Section 6: Venting and Condensate
-
Connect PVC venting for combustion gases.
-
Horizontal installations require slope for condensate drainage.
-
Check manufacturer recommendations—do not improvise.
For condensate tips specific to high-efficiency units, Trane’s troubleshooting page is a solid reference.
Section 7: Start-Up and Testing
-
Restore power and gas supply.
-
Run the furnace through self-diagnostics.
-
Check airflow, temperature rise, and listen for unusual noises.
-
Inspect all connections for leaks or vibrations.
If it’s running smooth, congrats—you just tamed a 96% AFUE beast.🔥
Section 8: Common Mistakes to Avoid
-
Not leveling the furnace → poor drainage in horizontal setups.
-
Loose duct connections → airflow loss and efficiency drop.
-
Skipping gas leak checks → danger. Don’t be that guy.
-
Ignoring self-diagnostics → costly troubleshooting later.
