I am eploring the insides of my pretty near dead heater unit, and think I have found the problem. Inside the combustion chamber is the remains of what looks like it was once a fan of some sort. Very rusty, and lots of sharp edges. The fan motor turns freely enough, and the little aluminium scoop-type fan is intact. Is there anywhere I can get parts for this heater, or maybe access to a drawing of it's insides so I could get a firm to make a fan up for me? Or does the forum think I should leave well alone, avoid risking C0 poisining, bin the thing and buy a boaty eberwhatsit/espar or etc?
PS - please hurry, it's getting coooooold on board!
