What do I have to do to clean my Harman Mark III for the closing of the heating season? Do I have to remove the pipe from the stove as well. I was thinking that if I did that the house would get fly ash all over the place. Any help would be appreciated.

Thankss,

Bryan

The best method is to remove the flue pipe completely, and wipe/wash the inside of the pipe and the stove with a solution of baking soda and water. Vacuum out the fly ash first of course.

The baking soda solution [one box in a 2-gallon bucket of water] helps to neutralize the acids in the ash. Normal summertime humidity will activate the acid in the ash, and you will have your flue pipes rust away just sitting there..

So: a good vacuum, and a wash/wipe with the soda solution, and if you want some form of rust preventative. or keep a light bulb burning in the stove to keep it slightly warm, to drive off the humidity.

When you vacuum out the stove make sure you get on top of the baffle, ash likes to lay up there. Another place it accumulates is inside the flue port on both sides between the interior jacket and the outside wall of the stove (if it is a rear exhaust and not a top exhaust). I can just barely get the hose from my small shop vac to fit in those cavities in the back, my larger shop vac won't fit.
