Bard part number 5818-021 is an OEM burner manifold used on select Bard gas-fired furnace sections, where it distributes incoming gas evenly to a four-burner setup through a 3/4 inch manifold body with four outlet ports. A worn, damaged, or leaking manifold can cause uneven ignition, poor burner carryover, nuisance lockouts, or unsafe operation, so replacing it with the correct Bard OEM manifold helps restore proper gas delivery and burner performance. Before ordering, confirm your furnace model and burner count, and match the manifold style and connections to your existing gas valve and orifices for correct fit and safe service.
* Orders less than $50 may incure a minimum order fee.
