Common Venting Tables 3 and 4 Apply to Vertical Common Venting into an Interior, Tile-Lined
Masonry Chimney

Do not vent into an exterior tile-lined masonry chimney.
Before connecting a vent connector to a chimney, inspect the chimney passageway to be sure that it is clear and free of obstructions. Clean the
chimney if it was previously used for venting solid or liquid fuel-burning appliances or fireplaces. Install the vent connector above the extreme
bottom of the chimney. Use a thimble or slip joint to facilitate removal. Attach the connector securely to the thimble. Do not insert the vent
connector into the chimney beyond the chimney wall.
