worked great for first year cannot find replacement parts

Bought this bistro heater 2 years ago last winter we used it 5 or 6 times worked great provided just enough heat to take the chill off while standing around the heater. Now the heater will not stay on after the pilot is lit. There are a few possible solutions all requiring replacement parts. Called the toll free number it not in service anymore. Found the manufactures web page it is not active. Still trying to find some spare parts but right now all I have is a expensive small table.More detail ...
