Optional Top Vent Pipe Clearances
#8 Installing into an existing chimney using the Optional
Top Vent option. (Figure 4.10)
This method provides excellent venting for normal operation.
This method also provides natural draft in the event of a
power failure. If the chimney condition is questionable* you
may want to install a liner as in method #6.
In some places in the US and Canada it is required that the
vent pipe extend all the way to the top of the chimney.
*The chimney should be inspected and cleaned before
installing your stove. If you discover that the chimney does
not have a clay tile liner or has cracks or flaking of the tile
liner you will need to install a stainless steel liner within the
chimney.
Be sure to design the venting so that it can be easily cleaned.
