9 Cleaning of the exhaust system will depend
upon the ash and debris content of your fuel. If
your fuel has a high ash content and/or
significant debris in it, your exhaust system
will require weekly cleaning. Cleaner fuels
will allow for monthly cleaning of the exhaust
system. Remove the exhaust pipe from the
back of your stove and remove any ash that my
have collected in the pipes. Replace the pipes
to the stove and seal with high temperature seal
tape. If you have installed proper clean out tees
you will not have to take the chimney sections
apart.
9 While you are doing the weekly cleaning, have the unit set on high and the draft knob all the way out.
This will help draw the fly ash to the back of the stove. (Remember the unit is not burning.) After
cleaning, push the draft knob back into the stop collar.
REMEMBER: A clean unit burns efficiently and will remain trouble free!
9 While you are doing the monthly cleaning, it is recommended to vacuum inside of firebox. Remove
firebrick located on the inside of the unit. Then remove the knock-out plugs located on the panel as
shown. Thoroughly vacuum ash out of area using a ash vacuum cleaner.
