WATER CONNECTIONS

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 125B

is provided with two elbow type connectors that must be

connected to the inlet and outlet fittings of the water valve

as shown in Fig 5. 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. 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. 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 6. To install the PRV,

a suitable fitting connected to an extension on a "T" fitting

can be sweated to the hot water line.

OPERATING INSTRUCTIONS

Before proceeding with the operation of the heater make

sure that the system is filled with water.

Make sure the water heater drain plug is closed. See Figure

7 below.

Fig. 7 - Water heater drain plug

Open the cold water inlet supply to the heater fully.

Open a hot water faucet to permit the water to fill the heater

and the piping and to eliminate the air trapped in the system

Close the hot water faucet after the water flows freely and

all the air has escaped from the system. The water heater

is now ready to work

FOR YOUR SAFETY READ BEFORE

LIGHTING THE PILOT

Warning: If you do not follow these instructions exactly, a

fire or explosion may result causing property damage,

personal injury or loss of life

A. This appliance has a piezo-igniter for lighting the pilot

burner. When lighting the pilot, follow these instructions

exactly.

B. BEFORE LIGHTING 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.

WHAT TO DO IF YOU SMELL GAS

- Do not try to light any appliance.

- Do not touch any electric switch; do not use any phone

in your building

- Immediately call your gas supplier from a neighbor's

phone. Follow the gas supplier's instructions.

- If you cannot reach your gas supplier, call the fire

department.

C. Use only your hand to push in or turn the gas control

buttons. Never use tools. If a button will not push in, check

to make sure the buttons are being pushed in the proper

sequence. Follow these instructions exactly. If control

button(s) are jammed, close the gas supply and call a

qualified service technician. Attempted forceful repair may

result in a fire or explosion.

D. Do not use this appliance if any part has been under

water. Immediately call a qualified service technician to

inspect the appliance and to replace any part of the control

system and any gas control which has been under water.
