Heater

Abstract

In certain embodiments, a heater comprises a fluid opening configured to communicate with a source of fuel. In some embodiments, the heater further comprises a first flow channel, a second flow channel, and a fluid flow controller in communication with the fluid opening. In some embodiments, the controller is configured to selectively permit flow of fuel to either the first flow channel or the second flow channel. In some embodiments, the heater further comprises at least one of a nozzle and an oxygen depletion sensor coupled with at least one of the first flow channel and the second flow channel.
