1. Turn the appliance combination control valve button to the “Pilot” position.
2. Push down the appliance combination control valve button and keep it depressed for several seconds,
so that all the air in the manifolds are clear.
3. Keep the gas valve button depressed and meanwhile push down the igniter button several times until
the pilot is lit.
4. Keep the gas valve button depressed for at least 10 seconds, so that the pilot sensor is heated up
enough. Release the gas valve button. If pilot goes out, repeat step 3 and step 4.
5. When the pilot flame is stable, slightly push the gas valve button down and turn to the “6 o’clock”
position QUICKLY. Heater will then operate normally. Now you can turn the control button to the
position as your desired.
To stop the heater shut off the external safety valve in gas inlet line (not part of the heater), then turn the
appliance gas valve to “OFF” position.
