A Big Buddy heater can continuously shut down when it detects low oxygen in the area. Big Buddy heaters are portable propane heaters that should only be used in ventilated spaces. You can use a Big Buddy heater indoors or outdoors as long as the air is circulating.

Since Big Buddy heaters are radiant gas heaters, they utilize fire in order to transmit heat to the objects around their vicinity.

As a result of this process, Big Buddy heaters expel carbon monoxide into the air. Carbon monoxide is a gas that can be poisonous when inhaled in excessive amounts.

Big Buddy heaters do not have a carbon monoxide reader, but they do have an oxygen detector. Once the Big Buddy heater detects that there is a low amount of oxygen in the air, it shuts down.

This safety feature is meant to prevent the user from inhaling high amounts of carbon monoxide. If the heater detects that the oxygen level is low, the device will assume that there is little to no air circulation in the area.

As a response, it will shut down to prevent emitting more carbon monoxide.

Another reason your heater is shutting down could be the altitude of your location. High-altitude areas can affect the heating process of a Big Buddy heater. In an area that's 7,000 feet above sea level, the heater may continuously stop operating.

If this happens, give the heater some air and allow it to stay idle for five minutes. Then you can try to reignite it.

Insert the cotton swab into the pilot hole to thoroughly clean the inner surface of the tube. Before returning the black grille, make sure that the alcohol has completely dried on the surface of the pilot hole.
