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.
- Position H3 (figure 7) is a garden hose thread boiler drain, that can be used to
drain the boiler or add water treatment additives to the system, such as inhibitors
or glycol.
- For information on locating the expansion tank and system fill, please see the
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).
