Confirm that the inlet gas pressure is between the minimum and maximum pressures allowed for this

appliance.

• If subsequent conversions are made, then a new conversion label must be placed on the water

heater to accurately reflect the gas type.

• Failure to correctly assemble the components according to these instructions may result in a

gas leak or explosion.

WARNING

1. Disconnect the electrical power.

2. Turn off the gas supply to the appliance.

3. Remove the four screws securing the front panel. Remove the front panel.

1. Press the “On/Off” button on the controller to start the unit. The LED display will illuminate, the

combustion fan will begin to run if water is flowing, and the spark will ignite the main burner.

2. This water heater has an automatic ignition system. When the main burner has lit, the “In Use”

lamp will glow red and the spark will stop.

3. Check that the burner flames are operating normally. The flame can be seen through the circular

window above the burner. When operating normally, the burner flame should burn evenly over

the entire surface. The flame should be clear, blue and stable. A yellow flame is abnormal and

maintenance is required (Figure 5).

TO TURN OFF GAS TO APPLIANCE

1. Set the temperature controller to lowest

setting.

2. Turn off all electric power to the

appliance if service is to be performed.

3. Turn the manual gas control valve

located at gas inlet of appliance

clockwise to the OFF position.

OPERATING INSTRUCTIONS

1. STOP! Read the safety information

above.

2. Set the temperature controller to

lowest setting.

3. Turn off all electric power to the

appliance.

4. This appliance does not have a pilot. It

is equipped with an ignition device

which automatically lights the burner.

Do not try to light the burner by hand.

5. Turn the manual gas control valve

located at gas inlet of appliance

clockwise to the OFF position.

6. Wait five (5) minutes to clear out any

gas. Then smell for gas, including near

the floor. If you smell gas, STOP!

Follow “B” in the safety information

above. If you don’t smell gas, go to the

next step.

7. Turn the manual gas valve located at

gas inlet of appliance counterclockwise

to the full ON position.

8. Turn on all electric power to the

appliance.

9. Set the temperature controller to

desired setting.

10. If the appliance will not operate, follow

the instructions “To Turn Off Gas To

Appliance” and call your service

technician or gas supplier.

FOR YOUR SAFETY READ BEFORE OPERATING

A. This appliance does not have a pilot.

It is equipped with an ignition device

which automatically lights the burner.

Do not try to light the burner by hand.

B. BEFORE OPERATING, 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 valve. Never use

tools. If the gas control valve will not

turn by hand, do not try to repair it,

call a qualified service technician.

Force or attempted 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.

If you do not follow these instructions exactly, a fire or

explosion may result causing property damage, personal

injury or loss of life.
