Installation Prior to installation, the chimney is inspected, cleaned, and prepared using chimney maintenance procedures and equipment recognized by our industry. Should the flue already be lined, the existing liner is removed.
All openings in the chimney structure, such as cleanouts, thimbles, and fireplace openings, are sealed, and weak areas in the chimney are braced.
The proper-size former is calculated for the particular heating application. The inflatable rubber former is then lowered and guided into the chimney flue. The former is then inflated and centered within the flue.
The Supaflu mix is prepared by adding water. The material is then pumped into the chimney from the top. It fills the space between the former and the inside of the chimney casing.
After the new Supaflu liner has fully cured, the former is deflated and removed from the flue, leaving a smooth, round, one-piece liner.
