This particular application represents a low mass boiler with a single system loop. Because the system
flow requirements may vary, or fall outside of the parameters of the boilers recommended flow, it is
beneficial to hydraulically separate the system flow, from the boiler flow. This can be achieved by using
a low loss header or closely spaced tee's on the system loop. A low loss header sensor can be installed
allowing better system control and increased efficiency. To program the boiler for this type of application,
please complete the following procedure:
