Protect the opening

If a cap is missing or damaged, avoid using an appliance if an obstruction or unsafe condition is suspected. Do not improvise a cover that could block the vent.

Ask about fit

A professional should identify the vent type, measure the opening and consider the appliance instructions. Ask whether the crown, liner or flue also needs review.

Verify completed work

Request the product details and a record of installation. Confirm the company has current insurance and experience with the system.

Find a local company and confirm scope

Company profiles are directory records, not a diagnosis or endorsement. Confirm current service area, qualifications, insurance, availability and written scope directly with the provider.
