Abstract
A fuel-fired heater can include a fuel tank; a housing assembly supported by the fuel tank, the housing assembly defining a chamber having an inlet and an air outlet; a fan located within the housing assembly; an air pump located within the housing assembly; an electric motor coupled to at least one of the fan and the air pump; a burner assembly located within the housing assembly, the burner assembly including a burner nozzle in fluid communication with the air pump and the fuel tank via a fuel line, and including an ignitor; and an electronic controller operating the electric motor and ignitor, the electronic controller including a proximity sensor oriented and arranged to sense an object located in front of the air outlet, wherein the electronic controller deactivates the electric motor when an object is sensed by the proximity sensor within a predetermined distance for a predetermined time period. In some examples, the heater includes a carbon monoxide sensor oriented and arranged to sense an ambient carbon monoxide level proximate the heater, wherein the electronic controller closes the fuel shut-off valve when a sensed carbon monoxide level exceeds a predetermined threshold for a predetermined period of time, for example 180 seconds. In some examples, the heater includes a fuel shut-off valve oriented and arranged to control fuel flow in the fuel line, wherein the electronic controller deactivates the heater by first activating the fuel shut-off valve to block flow through the fuel line and subsequently deactivating the electric motor after a predetermined time period.
