DO NOT BUY THIS UNIT!! This is a huge liability & we have received absolutely no support from Samsung. Our original unit was leaking propane so we received a replacement. Within a few months, the replacement unit was leaking propane again. We had a local fire inspector review the unit & confirmed the leak was from the unit. When working with customer service we were told it was a known defect, so we requested a refund. Our request for a refund has now been repeatedly declined.
