Before the installation and repair process can begin, the chimney must be inspected and thoroughly cleaned using the recognized procedures of the National Chimney Sweep Guild

.

Step #1: All openings in the chimney such as clean-out doors, thimbles, and fireplace openings are carefully closed and all weak areas are properly braced.

Step #2: The inflatable rubber former, the Supaformer, is lowered into the chimney. It is properly sized to the requirements of the heating appliance(s), thus providing optimum draft and insuring gases resulting from combustion are efficiently vented. If the chimney is lined with clay tile, the tiles should be completely removed.

Step #3: The Supaformer is inflated to the proper flue size and centered within the flue cavity using spacers. In offset chimneys, this spacing is vital to insure the required thickness of Supaflu® is achieved.

Step #4: The Supaflu® lining material (water added at site) is then poured inside the chimney and around the inflated Supaformer. The lining material requires approximately 24 hours to properly dry before the Supaformer is removed. The clean-outs and thimbles are then reopened and all braces are removed. The heating appliance(s) are then reconnected.
