Benefits of technology

This patent is about a heater assembly that can be used with different types of fuel. The heater has a housing with two fuel hook-ups, an inlet, an outlet, and a vaporizer. The assembly also has two actuation members that are positioned within the respective fuel hook-ups. When fuel is connected to the heater, the actuation members move to allow fuel to flow through the appropriate outlet. The technical effect of this design is that it allows for seamless switching between different types of fuel without the need for a separate vaporizer, which simplifies the operation and reduces the risk of leaks or malfunctions.

Problems solved by technology

However, such devices and certain components thereof have various limitations and disadvantages.

Embodiment Construction

[0061]Many varieties of space heaters, fireplaces, stoves, ovens, boilers, 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.

[0062]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 season, and accordingly stoc...

Abstract

A heater assembly can be used with a gas appliance. The gas appliance can be a dual fuel appliance for use with one of a first fuel type or a second fuel type different than the first. The heater assembly can include at least one pressure regulator, a housing, and an actuation member. The housing has a first fuel hook-up for connecting the first fuel type to the heater assembly, and a second fuel hook-up for connecting the second fuel type to the heater assembly. The actuation member can control a flow through the heater assembly based on whether the first or the second fuel hook-up is used.
