Followed nstructions from U-tube to set it up. The instructions it comes with are confusing as all heck. Installed it on my camper under the wing, and just hole-sawed some holes for the heater hoses. Wired it up, , put on the diesel and it fired right up! Produces more heat then we need, but we just open a window and it_ no problem. It doesn_ drain the battery to much overnight. Only thing I recommend is getting new hose clamps. The ones it comes with are too cheesy and the fuel will leak if you try to use them.
