I just bought this stove yesterday and got it all hooked up today I did the 20 min dry run like it said then load the hopper with a bag of pellets. The fire started and and ran for a about 15 or 20 mins then I got error code E2 fail to start. So I restarted it and it ran for about same amount of time then got the error again. The blower never kicked on either. Any ideas
