1.6 PROCEDURE TO BE FOLLOWED BEFORE PLACING
BOILER FEED SYSTEM IN OPERATION
1.6.1 CLEANING THE FEED SYSTEM
After installation is complete, the feed system should be checked for debris. Any debris found in
the tank, pump, or strainers should be removed before start-up. Mechanical floats should be
checked to make sure no debris is keeping the float from operating correctly. If a steam pre-
heater assembly as supplied, the pressure/temperature-regulating valve should also be checked
for obstructions.
1.6.2 LEAK TEST OF FEED SYSTEM AND PIPING
After completing the feed system installation, the piping connections, fittings, attachments and
adjacent piping must be inspected for leaks by filling the unit with water. Inspect all openings and
fittings for leaks, removing any obstructions if necessary for proper evaluation. Although the feed
system is inspected and tested at the factory, minor leaks in fittings and attachments can develop
from shipping vibrations or from installation procedures. It may be necessary to re-tighten such
fittings after installation and after the boiler feed system has been in operation for some time.
