    Abstract: A heater including a housing, a heating assembly having a burner, and at least one of an oxygen level detection assembly adapted to distinguish between a relatively normal oxygen level, a relatively low oxygen level and relatively unsafe oxygen, a carbon monoxide sensor and a combustible gas sensor. The heater may also include an indicator adapted to produce at least one of an audible indication and a visible indication in response to a detection of a relatively low oxygen level, a detection of a predetermined level of carbon monoxide, or a detection of combustible gas.

    Abstract: A heating assembly can include a switching valve which can include certain pressure sensitive features. These features can be configured to change from a first position to a second position based on a pressure of a fuel. The valve can be used with either a first fuel or a second fuel different from the first. The valve can become locked or be held in either the first or the second position. For example, a set fuel pressure can cause the valve to move to a closed position and the valve can become locked or held in that position. If the pressure decreases, the valve can remain in the locked position. Actuation of a reset switch can allow the valve to move to a new position, such as an open position.

    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.

    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 a fuel regulator valve including a main pressure regulator to maintain the fuel pressure, a first fuel source connection for connecting the first fuel type to the heater assembly, a second fuel source connection for connecting the second fuel type to the heater assembly, and an air shutter system. The air shutter system introduces air into the fuel discharged at the main burner nozzle before it is supplied to the main burner. The air shutter system can open the air shutter to two or more different positions to vary the amount of air introduced based on the type of fuel supplied.

    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 a fuel regulator valve including a main pressure regulator to regulate the fuel pressure, at least one auxiliary pressure regulator, a first fuel source connection for connecting the first fuel type to the heater assembly, and a second fuel source connection for connecting the second fuel type to the heater assembly. The one or more auxiliary pressure regulators introduce a backline pressure to the main pressure regulator, thereby adjusting the fuel pressure to fall within a predetermined range.
