Comfortably enjoy your backyard all year long with the Avanti propane powered patio heater. With 47,000 BTUs the range of warmth is generous to ensure you can focus on your outdoor activity rather than the cold. The built-in wheels allow easy movement of the heater to facilitate relocation. The simple push-button ignition control starts the heat in an instant and the safety auto shut off tilt valve turns it off if the unit is accidentally tipped or knocked over.
