SunGlo A244VE "Mushroom"-Type Hanging Gas Patio Heater
24 Volt Operation, Electronic Ignition, 50,000 BTU. The SunGlo A244 overhead patio heater works well when it is centrally located, as it heats in all directions. It is fantastic for large areas, and an excellent choice for over a round table. This 24 volt heater comes with a transformer and can be controlled by a switch at a remote location. It buzzes and lights when you flick the switch. Made in America by Infrared Dynamics.
In order for the bottom of the heater to be 6'8", the height of a standard door opening, your ceiling height will need to be at least 10'3" to stay outside safe flammable-clearance tolerances. In some cases, if mounting over a table, it may be safe to mount the heater a few inches lower.
