Using this patio heater is a breeze. First, make sure you have a refillable 48000 propane tank (not included). Once you've got the tank, fully assemble the heater as it requires full assembly. After assembly, connect the propane tank to the heater. Use the piezo ignition system to light it up quickly and easily. You can adjust the heat intensity based on how warm you want your outdoor space to be. When it comes to safety, always remember that the heater has an automatic safety shut - off feature, but still, place it in a stable and well - ventilated area. Do not use it in commercial settings. For maintenance, keep it clean and dry. Check the connections regularly to ensure there are no leaks. If you're going to store it, make sure it's in a dry place and disconnect the propane tank. And that's all you need to know to enjoy this great patio heater for many outdoor seasons to come.
