Brand new unit will not fire for the first time; it won't drop pellets Yellow light is flashing 3 times continuously, call light is on. I cannot find anywhere that tells me what the yellow light means. Also, I was under the impression that the fan is supposed to shut off after running for 10 minutes and it will not shut off. We've read the entire manual and nothing we've tried has worked. If anyone can please help me I would greatly appriciate it!! I have a cold house and a fustrated husband! Thank you!
