This took over an hour to assemble, then it wouldn't lite. We've had several of these heaters & knew right away that the switch was defective. This is just frustrating because to return is a time consuming hassle. Called the mfr & they are sending us replacement parts but of course they are on backorder. So we won't have our heater for the holidays & they don't know when they will be shipped.  I wouldn't buy a heater online ever again.
