Exhaust Port Caution: Exhaust port must not be allowed to be sub-merged in
water and port must remain free of obstructions. The fitting shall be installed in a
horizontal or a decreasing angle as provide from the Civacon factory. The exhaust
tube opening should not be allowed to rest on the manhole cover. The tube should
be overhanging the man-hole assembly.
Alternate exhaust configurations: If you believe that the exhaust tube may be
submerged in water at times due to inadequate drainage we recommend daisy
chaining all exhaust ports together and locate the exiting tube where it will not
be restricted (i.e. midway down the back of the tank).
