The kit is equipped with a 3/4" adapter for the pressure relief valve that is shipped with the boiler as shown in the drawing attached (in attachments to this article). It is strongly suggested that this location is used for the boilers pressure relief valve , but if the user chooses to put the the pressure relief elsewhere, this connection must be plugged.
To accommodate systems that use an indirect water heater, this manifold is equipped with indirect water heater connections as shown in the drawing attached (in attachments to this article). The manifold is shipped with these connections "capped" . The connections must remain "capped" if not used. If an indirect water heater is to be connected, remove the caps and connect to the indirect water heater piping.
