Resetting a tilt switch on a patio heater requires the following steps:
* Turn off the power supply to the unit.
* Disconnect any electrical connections from the switch and remove it from its mounting bracket.
* Check for any defects or damage that may have caused it to trip, such as broken wires.
* Clean any debris or dirt that could be preventing proper operation of the switch.
* Re-install it onto its mounting bracket and reconnect all electrical connections correctly.
Finally, turn on the power supply again to reset your tilt switch and restore heating operations.
