Figure 7a: Individual Vents – PREFERRED Installations
NOTE 1:
For high wind, wind blocked sites, a tee may be installed at the fresh air inlet. The leg of the
tee connects to the combustion air intake. The branches of the tee can be in the horizontal or
vertical direction, as determined by the system designer and site conditions.
NOTE 1A:
Flue terminations should never be stacked. Condensate from the upper can freeze over and
block the lower.
