In addition to the methods shown by A, B, C, and D of Figure 8, a listed factory-built wall pass-through system
may be purchased and installed according to the instructions packaged with it to provide a safe method of
passing chimney connector through a combustible wall for a connection to a masonry chimney.
CONNECTION OF CHIMNEY CONNECTOR TO A MASONRY CHIMNEY WHEN CHIMNEY CONNECTOR
If the chimney connector does not have to pass through a combustible wall to get to a masonry chimney, simply connect
the chimney connector directly to the masonry chimney's chimney thimble as described and shown by parts C and D of
Figure 8. Remember, the chimney connector should extend into the chimney thimble to the innerface of the chimney flue
but not beyond; if the chimney connector is extended through the chimney thimble into the chimney flue, resistance to the
flow of smoke and gases up the chimney will occur; that flow resistance will have an adverse affect on the operation and
performance of the heater and venting system.
