Embodiment Construction

[0031] Many varieties of space heaters, fireplaces, stoves, fireplace inserts, gas logs, and other heat-producing devices employ combustible fuels, such as liquid propane and natural gas. These devices generally are designed to operate with a single fuel type at a specific pressure. For example, as one having skill in the art would appreciate, some gas heaters that are configured to be installed on a wall or a floor operate with natural gas at a pressure in a range from about 3 inches of water column to about 6 inches of water column, while others operate with liquid propane at a pressure in a range from about 8 inches of water column to about 12 inches of water column.

[0032] In many instances, the operability of such devices with only a single fuel source is disadvantageous for distributors, retailers, and / or consumers. For example, retail stores often try to predict the demand for natural gas units versus liquid propane units over a given winter season, and accordingly stock thei...

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.
