Cleaning fines under grate

This is what I found when cleaning my econo 1, I took the combustion motor out to clean it good and oil it. I looked in the hole and could see the fines under the grate. I took my vac and cleaned it out through the combustion fan hole. It was much easier than removing the grate.

Hope this helps someone.

That's the way I do my Keystoker as well, make sure to clean all the plate holes first. I use a brush for a refrigerator cooling fins to loosen everything up while I vacuum, works well, kills two jobs at once & you don't have to reseal the grates.

Also make sure the holes are clean, a small drill bit or piece of wire works good too.

Yes, removing the combustion blower and vacuuming in under the grates is pretty easy.

That is definitely the way to go. By removing the grates you run the risk of not sealing them properly and increasing the chance of a hopper fire if they are not sealed correctly.
