Hi everybody. Does anyone know if the secondary air plenum on the Hearthstone Heritage 8024 can be removed to access more of the stove for cleaning? I have seen a video for the 8023 but mine seems different. Mine is vented out the rear into a T and flexible liner up chimney. I can clean it from roof but to remove the dust and clean T snout I have to disconnect pipe. If I could remove the secondary air plenum I could access the snout and vacuum out the dust without disconnecting pipe. First year with this stove. In our last house we had a Jotul Castine which we liked a lot. This Hearthstone a little finicky but did produce a lot less creosote. TIA. Enjoy the summer, woodburning season on the way!
 
The tube and baffle can be removed. It's a bit involved, but covered in detail on pages 26-27 of the manual.

Thanks for reply. I only see in manual how to remove baffles and catalyst. I want to remove the secondary air plenum I think. It is the part that holds the air tubes. In one video for the 8023 the guy says it ways 50 pounds. I think the 8024 is different. I found a little AI article that said the the top had to be taken off. it wasn't very clear. Maybe I should just disconnect pipe and pull stove out every year?
 
Why remove the plenum for cleaning?
 
I just thought it would be better to leave the pipes together. Also I have to move the stove to do it. Maybe I am just spoiled. At my old house I had a Jotul Castine. It was easy to take top off, then remove a chamber and I could brush thru pipe to the T and I could easily remove the bottom foot of the T to remove the dust. This stove with baffles removed I can see into pipe but the access is pretty small for a vacuum or brush. If the plenum was removed I could easily access T with a brush and vacuum. Both stoves sit in front of fire place and vent out the back. How many times can you take stove pipe apart and put it back together? My old stove was hooked up to Supervent insulated pipe. I had a foot long piece attached to bottom of T that could be easily removed by removing a clamp and twisting pipe. This house the stove is hooked up to a T that is hooked to flexible liner. Just had a thought. If the screw holes get worn out I could use bigger screws. The dealer that sold me the stove said I could easily access the pipe thru the stove but his crew that hooked it up said that wasn't right. I really don't want to ask the dealer, was not happy with the job they did. I am thinking maybe the stove top has to be removed to get the plenum out.
