3.9.3.1 Single Opening Vented Cavity
Option Alternative Installations
•
Figure 3.20 shows an alternative installation method where you
cap off the fireplace cavity so the air discharge opening can be
located further down the fireplace chamber. 1-1/2” (38mm) is
the maximum drop for framing the air discharge opening to the
fireplace enclosure top. This avoids trapping heat in the upper
areas of the vented cavity enclosure. Framing the outlet any
lower than 1-1/2” (38mm) will cause over heating and create a
fire hazard. This installation method can alleviate any possible
concerns with paint discoloration from heat or dust.
•
Figure 3.20 is shown with an air discharge overhang in front of
the air discharge opening. This optional installation method can
provide a means to visually hide the air discharge opening.
