Goodman Furnace: Venting restrictions and vent system check
Venting restrictions and vent system check on a Goodman furnace: This furnace cannot connect to Type B, BW or L vent or vent connector, and cannot enter any part of a factory-built or masonry chimney, except as a pathway for PVC. Never common-vent it with another appliance or a solid-fuel vent. Use only the no-hub connectors shipped with the unit. Before leaving, check the whole flue system inside and out for sealing, because leaks can cause carbon monoxide exposure.
Applies to: All vented installations
How to fix venting restrictions and vent system check: step by step
- Confirm the vent is not Type B, BW or L and is not common-vented.
- Confirm the vent does not run through a chimney except as a PVC pathway.
- Use only the supplied no-hub connectors.
- Inspect the full flue system inside and out for leaks before startup.
