A heater attachment for an L.P. gas container having a gas outlet, the attachment comprising:
- a. an adaptor means threadedly attachable to the gas outlet and having an inlet orifice receiving gas from said outlet and a restricted outlet orifice means,
- b. base means operatively attached to the adaptor means,
- c. burner means including a tubular mixing chamber mounted to the base means and disposed in coaxial relation to the restricted outlet orifice, said chamber having a plurality of lower air inlet openings and an open upper end,
- d. a flame chamber having an open upper end and an open lower end disposed in coaxial relation to said mixing chamber and separated therefrom by an annular air opening,
- e. flame shield means disposed in spaced relation above said flame chamber in overlapping relation thereto and including an inner conical member intercepting the path of the flame an an outer conical member having a larger diameter than said inner conical member and spaced from said inner conical member to define an insulating passage thereby, and
- f. support means operatively attached to said base means and carrying said flame chamber above the base means, said support means holding said flame shield means in spaced relation from said flame chamber and holding said conical members in spaced relation from each other to define said passage.
