Connecting To An Existing Chimney
The Clarity may be connected to an existing ma- |
sonry chimney by using aSimpson |
version kit #934. |
With this kit and a 4" flex linner in the chimney the |
flue gases exit through the 4" linner and the outside |
air comes down the chimney in the space between |
the chimney and the linner. This method allows you |
to install the Clarity your chimney and still get the |
added efficiency provided by direct venting. |
The use of an existing chimney as an
air intake is not covered under the ANSI
