3. It is recommended to use the shortest length cable that will reach between the boilers and create a neat installation. Do not run
unprotected cables across the floor where they may become wet or damaged. Avoid running communication cables parallel and close
to or against high voltage (120 volt or greater) wiring. HTP recommends that the maximum length of communication bus cables not
exceed 200 feet.
4. Route the communication cables through one of the knockouts in the cabinet.
5. Connect the boilers in a daisy chain configuration as shown below. It is best to wire the boilers using the shortest wire runs rather
than trying to wire them in the order that they are addressed. The communication bus jacks on the customer connection panel are
interchangeable so you can use either one or both in any order to connect the cable.
If you have connected the boilers to each other properly, there will be no open communication connection ports.
