to no less than 1/2 inch diameter to allow the full flow capacity. Threaded connectors are supplied with this heater for both the hot and cold water fittings. These fittings permit 1/2” NPT connections to be made. Be certain there are no loose particles or dirt in the piping. Blow out or flush the lines before connecting to the AquaStar. A ball valve should be installed on the cold water feed line to facilitate servicing the heater.
For installation on a private well system, be sure that the water pressure is set between 30 and 50 psi.

Connecting the pressure relief valve (PRV)
A listed pressure relief valve supplied with the heater must be installed at the time of installation. Should a discharge line be added to the PRV no valve is to be placed between the PRV and the heater. No reducing coupling or other restriction may be installed in the discharge line. The discharge line must be installed such that it allows complete drainage of both the PRV and the line. The location of the PRV must be readily accessible for servicing or replacement., and be mounted as close to the water heater as possible See Fig 4. To install the PRV, a suitable fitting connected to an extension on a “T” fitting can be sweated to the hot water line.
