Re-lighting your Gas Hot Water Tank System

Rinnai Hotflow tank hot water system, can run on electricity or gas

Is your hot water coming out of your tap cold?

If you have a Gas Hot Water Tank, before calling a plumber, you can first check if the pilot light has gone out.

You do this by:

  • Go to your hot water tank, find the access panel and open the flap. There may be instructions on the flap on how to re-light, if not read on…
  • Turn the gas knob “off”. Wait at least 5 mins for unused gas to dissipate.
  • After 5 mins, turn the know to the pilot position (instead of saying pilot, it might have a flame symbol)
  • Locate the ignition button (may be a small red button you can push)
  • While pressing the knob down, press the ignition button until the pilot light comes on. You might have to repeatedly press the ignition button for it to work.
  • Once the pilot light comes on, keep holding the knob for another 20-30 seconds.
  • If it goes out, try the process again.

Hopefully this works! But if you find your pilot light is repeatedly going out, you will need to book a plumber to assess.
