Installation
Basic Plumbing
This is a basic plumbing hook up. Your system may vary depending on many factors. Therefore, we recommend having
experienced personnel do the plumbing.
This is only one of many layouts possible. Cirulator pumps, zone valves, and thermostats are not supplied with the unit
because the amount and type of these parts vary with every system. It is best to have a professional plumber do the job.
