Well, it's quite easy to operate this heater. You need a propane tank of 1 lb and install it on the side dedicated to the heater to start it. If you wish to connect the heater to a bigger tank, you can use an extra hose to secure it. Once the tank is installed, you need to press the igniter button and hold it for around 30 seconds. When the heater ignites, you can choose the required heat setting, and that's it.
