Equipped with factory-installed high limit switches and thermoelectric safety valves, you can feel comfortable using these heaters on any jobsite. Just plug the heater into a 115-volt outlet, hook up the hose and regulator to a 20 lbs (or larger) propane tank, and you're ready to take the chill out of any job. Equipped with quiet burner technology, this model operates quieter than standard propane forced air heaters by as much as 50%. Typical uses include construction sites, patios, factories, sporting events, utility and out buildings, and farming functions.
