Safety Information

Using the wrong type of propane heater indoors can have serious consequences. This heater is specifically designed to be safe for indoor use, but you should still use caution. Be sure to check the heater often to make sure it is still in optimal condition. If any propane heater is in disrepair it can expose you and your family to carbon monoxide.

Carbon monoxide is a colorless, odorless, tasteless gas. Carbon monoxide poisoning can lead to headaches, neurological injury, or even death. If you develop a headache, nausea, or become fatigued, turn the heater off and go somewhere with fresh air.

How to Use the Portable Buddy

This heater is simple to use. All you must do is swivel the knob to turn the knob to the pilot and push. The ignitor system kicks in and lights the heater for you. The Piezo Sparking System makes the ignition quick and easy. You can leave a window open for ventilation, although this heater does come with an oxygen sensor and will turn off if it detects carbon-monoxide, so you can feel safe in using it.
