Hello, I'm new to the group and in need of some help. We bought a house a year ago and it has a Montgomery ward franklin heater 686830R in the sun room. It doesn't have the vents attached and we can't find them anywhere. I'm not even sure if its called a pellet stove? My husband wants to use it. Not sure if We would need anything else besides the vents? Or if we should just buy a new one. Are these safe?
