ABSTRACT:
The heater includes a jacket unit connectable to the cooling system of an internal combustion engine, the jacket unit forming a central cavity in which a catalytic burner unit is suspended by means of a bolt that extends upwardly through an upper opening in the jacket unit. Overlying the jacket unit is a perforated dome-shaped cap having a hole through which the bolt extends so that a nut applied to the upper end of the bolt clamps the perforated cap against the upper end of the jacket unit, at the same time suspending the burner unit within the jacket unit's cavity. Within the cavity is a fixedly positioned ring through which the bolt extends, the bolt having a collar that abutts the underside of the ring when the nut is fully tightened. The catalytic burner unit also includes a feed tube extending downwardly therefrom. A second perforated dome-shaped cap underlies the jacket unit having a hole through which the feed tube extends. A sleeve of catalytic material is included in the burner unit. In one instance a glow plug is employed to initially ignite the fuel supplied through the feed tube and in a second instance a heating wire is wrapped around the sleeve of catalytic material to initiate the burning action. At the upper end of the feed tube is a wick in one embodiment and a propane nozzle in a second embodiment. Provision is made for attaching the heater to a specially designed portable tank.
