Installation & Servicing Instructions Rinnai E-Series

To protect the entire heating system we recommend installing a dirt particle
trap in the return circuit. When the boiler is installed to an existing heating
system this trap is required. Use of a Y strainer is not permitted as substitute
for a dirt trap.

Rinnai Boiler Applications Manual.
The boiler is designed to be used on pressurized heating systems only (closed
loop).
If the boiler is to be installed in a system that utilizes zone pumps and not zone valves
a low loss header plumbing kit should also be installed (part number: 804000061).
If the pressure drop in the loop/system is greater than the available head pressure
from the boiler pump a low loss header plumbing kit should be used (part number:
804000061).
