I’ve had this heater for about three weeks now, IT’S BEEN NOTHING BUT TROUBLE!!! The main control it has you CANNOT SET SPECIFIC PARAMETERS LIKE MOST OTHERS!! That wasn’t specified in description! Fuel pump quit a few days in. Was able to remove pump and get working again for a day then quit again. Ordered new pump worked wonderful for 4-5 days then quit again. I’ve spent WAY more time trying to figure this thing out than ITS WORTH. Spend few more bucks and get one that you can control the parameters. I know a few people that have same priced units that work great!
