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.

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

Fig. 6 - Pressure Relief Valve

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 installation on a private well system, be sure that the
water pressure is set between 30 and 50 psi.

LIGHTING INSTRUCTIONS

1. STOP! Read the safety information above on this plate.
2. The gas valve must be turned off by depressing the

gas valve off button (     ).

3. Wait five (5) minutes to clear out any gas. If you smell

gas, STOP! Follow “B” in the safety information above
on this plate. If you don’t smell gas, go to the next step.

4. The pilot burner is located behind the peephole in the

front center of the jacket directly below this instruction
plate.

5. Depress PILOT button (    ) and light pilot by pushing

PILOT INGITER button (    ).  This may have to be
repeated.

6. Observe the pilot flame through the peephole. The pilot

button (      ) should be held down at least 10 seconds
with pilot burning.  When the pilot button is released the
pilot should continue to burn.

- If the gas valve button does not pop up when released,

stop and immediately call your service technician or gas
supplier.

- If pilot does not stay lit, repeat steps 1 through 6.
- If pilot will not stay lit after several tries, depress the

OFF button (     ), and call your service technician or gas
supplier.

7. When lit, depress the ON button (        ). The heater will

now fire when water is drawn at a rate greater than the
threshold flow rate.
