Using this tabletop heater is easy. First, assemble the parts as the partial assembly required. Then, connect a refillable 9500 propane tank (not included) to the heater. Use the piezo ignition system to quickly and easily light the heater. You can adjust the heat intensity according to your personal preference. When using it, make sure it's under a covered patio and away from flammable materials. Since it has an automatic safety shut - off feature, you don't have to worry too much about safety. For maintenance, keep the heater clean and dry. Check the connections regularly to ensure there are no leaks. If you're taking it on a trip, handle it carefully because it's portable. And always remember, this heater is for household use, not for commercial purposes.
