1.4.6 Sidewall Vent Termination
DIRECT VENT - TWO PIPE
Sidewall direct vent applications shall be vented as follows:
• Both the inlet and exhaust terminations should normally be located on the
same plane (side) of the building.
• The exhaust outlet is to be placed so as to reach 24" minimum above the
down-turned intake - to avoid intake re-ingestion of exhaust gases.
• The elevation of both pipes can be raised in “periscope style” after passing
through the wall, then congured as in Figure 8, to gain required clearance.
