Sidewall Single Pipe Vent Termination
Sidewall direct vent applications shall be vented as follows:
• Both the inlet and exhaust terminations should be located on the same side of the building and the exhaust
termination should be placed so as to reach 24" minimum above the down-turned intake - to avoid re-circulation
• The elevation of both pipes can be raised in “periscope style” after passing through the wall, then configured as in
Figure 6, to gain required clearance.
• Ideally use a 45° elbow on the exhaust termination to launch the plume up and off the sidewall, for protection of
wall. A bird screen is useful to guard against foreign objects.
Unbalanced Terminations
Eco King also permits unbalanced flue terminations where exhaust is terminated at the roof of building and intake is
piped directly to the boiler from building side wall. Follow guidelines for each as noted above in roof and wall
termination sections. For example, in the roof termination section it states a straight pipe can be used as a vent
termination at the roof as rain filtration into the boiler is not an issue. For air intake on the side wall, ideally, a 45
elbow is used to prevent rain ingress.
