So Easy
Not only does this heater work great, but it was so easy to convert from propane to natural gas. I bought the heater for a rental property that had propane and then moved it to my house where there is natural gas. There were no expensive and long list of parts to convert it - just one $30 small part that took no time to install. Too easy.

Very Happy
I have had it for about a month now. It fired right up and works extremely well and works fast. The savings in time and gas are amazing.<br>
