I got the Eco 45 pellet stove with my new house. The pressure switch hose I disconnected at the brass nipple end and I can't find it he nipple to connect too. The droplet company says it connects to the exhaust fan or exhaust channel but I can't find it unless the brass fitting is missing. I almost need an "X" marks the spot or something. I'm to old and disabled and too cheep to look any more. No YouTube or manual shows me. Can anyone help me please. Or it's the pay the service guy for my cheep old butt for me.
