chrisasst said:Great info, my ef2 is really hard to pull and push. I guess I will have to try the nut and see if that works. It may not help either that the rod seems to be bent. I haven't taken it out to really check it though.
Hello chris
My rod was bent also but I straightened it with a hammer. Not perfect but works great. You can also buy a new rod for $29.90 (broken link removed to http://woodheatstoves.com/heat-exchanger-rod-wknob-p-9854.html)
Good Luck.
