The burner was good but the soleinoid valve, that was not working, has been tested according to supplier recommendations and not replace. We sent video, we paid local technicians that showed that valve was not working, we wasted tme and money and supplier didin't replace any part. The Alibaba support was very inefficient, waiting more than 2 months in solving the issue and fixing a refund, after suddenly close the issue without writing me and refund Quality: Service:
