ABSTRACT:
A sealed combustion, low profile gas-fired baseboard heater has a heat exchanger which is U-shaped, and which has upper and lower horizontal sections. Appropriate inlets are provided for air and combustion gas, and a gas valve. The air inlet may be coaxial with an exhaust for combustion gases. The heater may include a combustion blower, in which case the heat exchanger can include fins and other features to improve heat transfer. A natural draft version includes a larger bore tubular heat exchanger. Ignition can be by way of a pilot. Alternatively, a hot surface igniter, with safety lockout-timing device, can be used.
