I recently bought the Enviro M55 Cast and had it installed yesterday, pictures shown below, yes it did actually happen. I noticed a high pitch hum when the auger would turn. It sounds like the motor is straining to turn the auger. I also noticed that after the initial start up phase the flame would die down and would not rise above the burn pot regardless of which button I pressed. The pellets would trickle a few at a time, sometimes none at all. I took j-takeman's advice and emptied the hopper of all the Stove Chow pellets. I examined the auger to see if something was blocking the way, like a forgotten piece of packing material or a manual left behind. There was nothing that I could see. Next I removed the rear panel and examined where the auger connects to the motor. I checked the ring that has the screw in it that tightens the auger to the motor and it was tight. I turned on the stove and watched the auger turn where it connects to the motor, no slippage. The agitator turns about an 1/8th of a turn when the auger kicks on. Not sure what else to do, other than call the dealer and wait for them to come out and service it. Any suggestions are greatly appreciated. The white surge protector is only temporary. Big thanks to my brother for making the custom hearth for us. Here is a video of the auger turning.
