Abstract: Multiple candle wicks include a wick construction having at least one pair of substantially parallel elongate candle wicks which are laterally separated from one another, and a ladder filament connecting the pair of candle wicks. The ladder filament extends back and forth between the candle wicks (e.g., at substantially 90° relative to the elongate axes of the wicks) and is of sufficient flexural stiffness so as to resiliently bias the pair of candle wicks from a compacted position and into a spread position following release of an applied bending force. A multiple candle wick assembly includes such a wick construction whereby the crossing portions of the ladder filament are bent around an exterior circumferential portion of an elongate core element so as to assume a general U-shape around the exterior circumferential portion thereof and to place the candle wicks into the compacted position thereof.

Abstract: A portable indirect fuel fired heater includes a burner assembly having a fuel burner to deliver fuel from a fuel supply to a combustion chamber of the heater and a combustion air blower to deliver combustion air to the combustion chamber with the fuel for combustion in the combustion chamber to produce exhaust gases. A heat exchanger receives air to be heated in heat exchanging relationship with at least a portion of the combustion chamber. A sensor senses an oxygen level as a partial pressure of oxygen in the exhaust gases. A controller operates an actuator operatively connected to the burner assembly to controllably vary the delivery rate of combustion air and thus vary the ratio of the air and fuel responsive to the oxygen level sensed by the combustion sensor so as to maintain the sensed oxygen level at a prescribed set point level stored on the controller.

Abstract: Exemplary embodiments of a pelletized fuel delivery and combustion system are disclosed. Certain embodiments are configured to be detachably mounted to the exterior of a kettle-styled grill such as, but not limited to, a Weber® charcoal grill. When mounted to the kettle-styled grill, a firebox is external to the kettle and delivers thermal energy and smoke to the interior of the kettle by, and through, at least one damper port in the kettle. In this way, embodiments of the solution do not require significant, if any, modification to the kettle-styled grill in order for the kettle-styled grill to use a pelletized fuel source. Embodiments may also include temperature loop control and/or a thermal energy and smoke distribution plate configured to be set within the kettle of the grill.
