Claim:
1. A dual fuel heating assembly comprising: a housing comprising at least one inlet, at least one first outlet, and at least one second outlet, the housing configured to direct a fuel flow therethrough and defining: a single pressure selector valve configured to selectively block the fuel flow at the single pressure selector valve depending on a pressure of the fuel flow, the single pressure selector valve comprising a single movable valve body positioned at least partially within the second flow path; wherein in a first position of the single movable valve body, the second flow path is closed by the single movable valve body, and in a second position the single movable valve body allows the fuel flow through the second flow path, the first flow path remaining open independent of the position of the single movable valve body when fuel flow is flowing to either one of, or both of the at least one first outlet and the at least one second outlet; wherein the single movable valve body is configured such that movement between the first and second positions is controlled by the pressure of the fuel flow flowing to the single pressure selector valve; and a control valve having a first position that allows a first amount of the fuel flow through a control valve body and a second position that allows a second amount of the fuel flow through the control valve body, the control valve positioned in the second flow path downstream from the single pressure selector valve.
