Water Connections

When facing the heater, the cold water inlet is on your right and the hot water outlet is on your left.

Although water piping throughout your structure may be other than copper, we recommend that copper piping be used for at least three feet before and after the heater (follow local codes if more stringent). Keep water inlet pipe to no less than 1/2 inch diameter to allow the full flow capacity. Remember that water pressure must be sufficient to activate the heater when drawing hot water from the top floor. If the hot and cold connections to the heater are reversed, the heater will not function. The AquaStar 125HX is provided with two connectors that must be connected to the inlet and outlet fittings of the water valve as shown in Figs 5 and

6.½” copper or brass fittings work best when connected to the connectors. See Fig 6.

These fittings seal to the water valve by means of a union connection with a washer type gasket at the joint. No pipe dope or thread tape is to be used at these joints. Be certain there are no loose particles or dirt in the piping. Blow out or flush the lines before connecting to the AquaStar. Full port valves should be installed on both the cold water feed line and the hot water outlet 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.

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 7. To install the PRV, a suitable fitting connected to an extension on a “T” fitting can be sweated to the hot water line.

Connecting the pressure relief valve (PRV)

A listed pressure relief valve supplied with the heater must be installed at the time of installation. 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.

A.This appliance is equipped with electronic ignition for lighting the pilot and main burners. When turning the heater on, follow these instructions exactly.

B.Before operating the unit, set the On/Off switch to the

On ( ) position. The On/Off switch is located behind the flip-down coverplate on the front panel strip. Smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
