WATER PIPING:
Boiler applications:
•
Use primary/secondary piping configuration.
•
Common pipe diameter must be sized for less than 4.0 ft/sec; common pipe length must
be 3 to 5 times its diameter.
•
Single unit application - relocate supply temperature sensor from boiler header to system
piping.
•
Multiple unit application - install Cascade header temperature sensor in the system piping
(see AERCO Cascade Sequencer user manual (GF-146-CS) for installation details).
Water heating applications:
•
A storage tank must be used. See below for basic
piping configurations.
•
An anti-scald valve must be used and installed in
accordance with local codes.
Ensure that the minimum system flow is met
per chart and table below, otherwise the flow
sensors will automatically stop the burner.
