Water Connections; Safety Before Lighting The Pilot - AquaStar 125B LP Installation And Operating Instructions Manual

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.
