What homeowners should consider
Existing chimneys and vents should not be assumed suitable. Materials, sizing, clearances, terminations, and combustion air require review.
Conditions differ by home. Equipment age, fuel type, access, venting, drainage, electrical capacity, and local requirements can affect the right next step.
Plan a safe next step
Do not open, modify, or bypass safety controls. Gas, electrical, plumbing, drainage, and venting work must be completed by appropriately qualified professionals and follow the requirements that apply to the home and municipality.
