I am new to wood furnaces having just bought a house that has a woodgun180. I did receive a short tutorial from previous owner but would like more in depth. Also want to make sure it is operating efficiently. I do also have oil furnace as backup and seem to be burning oil as well as wood. I know there will be some crossover when I shut down to clean etc but just not sure how it all coordinates. Was hoping to find someone who services these or installs in MA
