VERTICAL TERMINATIONS (175,000+ BTU/HR)
Figure 9B: Vertical Termination (175,000+ BTU/Hr models)
For inputs of 175,000 BTU/Hr or greater, all termination pip-
ing and fittings are 3”. Do not reduce before penetrating
the wall.
The vertical inlet air termination requires a return bend or
two short or long sweep radius 90° elbows to keep the inlet
downward and prevent entry of rain. These elbows are con-
sidered part of the termination and should not be included
when calculating the maximum allowable vent pipe length.
Refer to figure 9B for the proper location of the air inlet
with respect to the exhaust outlet termination. The vertical
exhaust outlet termination is a 3 inch pipe which terminates
at least 12 inches above the inlet air termination.
The air inlet and exhaust outlet terminations must be at
least 12 inches above the roof line or anticipated snow
levels as shown in figure 9B below.
