Hello, I purchased the Mt. Vernon Pellet Stove AE, MTVERNON-AE-MBK, serial 00700109713. It was disassembled when purchased. I connected the thermostat wires. However, there are two green wire leads still disconnected. One is coming from the power supply input line voltage and the other from near the thermostat wire post from what looks like the 12 volt battery back up cable plug. I assume these two green wire leads are grounds and should be connected to the stove frame? Can anyone please confirm or deny my assumption and provide instruction on where to connect these two green wire leads? Pictures attached for reference. Thank you in advance for your response.
