Regulator reset procedure

You may need to reset the tank regulator if:

  • The tank was allowed to become empty and has now been filled.

  • The gas isolation valve (under the tank hood) has been turned off (as illustrated on the back page).

  • The supply to the house has been disconnected and re-connected. Resetting the regulator is done by operating the Under Pressure Shut Off (UPSO) as shown. Before resetting the UPSO you must perform the following checks:

  • Turn off all gas appliances and the emergency control valve on the exterior of the building.

  • Check that the gas isolation valve, under the tank hood is open. Turn it anti-clockwise if it is fully or partly closed.

Once completed, take the following 5 steps to reset the regulator:

  1. Resetting the regulatorRemove the cover cap marked ‘UPSO reset’ on the regulator.
  2. Grip the spindle firmly and pull - do NOT push. You should be able to both hear and feel if the regulator has reset.
  3. Release the spindle gently and replace the cover cap.
  4. Slowly open the emergency control valve on the exterior of the building. Re-light any permanent pilots and check that all appliances will light to ensure that the gas supply has been re-established.
  5. If the gas supply does not re-establish itself then check that all appliances are turned off and then repeat the reset procedures as detailed above.

Important:

If, after two attempts the gas supply has not been re-established or you have any doubts or difficulty, contact the Calor Emergency Service on 0845 7 444 999.
