A decorative torch produces a luminous flame and can be used on a patio or balcony as an aesthetically pleasing light and/or heat source. A filter received in a passage of a fuel tube minimizes acoustical noise generated by the flow of fuel from a pressurized fuel source. The fuel tube may omit any vents to enhance the luminous character of the flame and/or to reduce acoustical noise. Alternatively, a sleeve may be used to seal one or more vents. The sleeve may, or may not, be positionable on the fuel tube to adjust the number of vents sealed.
