Propane regulator guide

We've put together a handy video and guide which gives you a step-by-step guide on how to correctly and safely connect propane gas bottles to your appliances, with details of how to remove and replace regulators.

How to connect a Propane gas bottle

  • Check that the valve hand wheel is off by turning it clockwise
  • Remove the protective plug and leave it hanging (to replace later)
  • Check the bullnose connection on the regulator for any damage before connecting
  • Make sure the gas bottle connection is tight
  • When you need gas, turn the valve hand wheel

IMPORTANT: This type of gas bottle has a female valve connection. Check the connection is clean and undamaged. Always use the correct size spanner and fully tighten.

How to disconnect a Propane gas bottle

  • Turn the valve hand wheel off (clockwise rotation)
  • Except for multi-bottle installations with a changeover valve, turn off the gas tap if it’s fitted to the appliance. Wait until the burner and pilot lights have gone out. For installations with a change-over valve, you only need to turn off the empty gas bottle
  • Never remove the regulator (or connecting nut) with the bottle valve open
  • Use a spanner to remove the regulator (or connecting nut – left hand thread)
  • Replace the protective plug into the valve outlet
