Common Chimney Terminations
Two chimney terminations are offered by Isokern, the DM 54
large crown cap and the DM 54 small crown caps. These are cement
crown caps designed to provide a weather cap to the DM 54 chimney
system. Their design is typical of the cement caps found on traditional
masonry chimneys.
Due to owner preference and architectural design criteria other
chimney terminations can be used alone or in conjunction with the crown
caps. Special design caps may be designed and constructed by others and
must be fashioned so as not to restrict the flow of smoke and gasses out
the top of the flue opening. Figure 75 depicts common chimney termina
-
tions.
Check with local building codes to establish the need for chim
-
ney caps and spark arrestors or for any limitations to their design and
use.
