operation, and fill system through feed pressure. Manually
open air vent on the compression tank until water appears,
then close vent.

Purge all air from system before heater operation. This
can be normally accomplished by opening a downstream
valve.

CAUTION: An air vent valve should be installed at
the highest point in the system for proper operation. If
water piping is located higher than the header, an air
vent valve should be located at the highest point in the
installed system.
Venting System Inspection
1. Check all vent pipe connections and flue pipe
material.
2. Make sure vent terminations are installed per code
and are clear of all debris or blockage.
