Cleaning of your flue pipe
After one week of use you should check your flue pipe to see the rate of creosote buildup. If it is clean then you can push it back another week. You can do this until you see the flue pipe needs to be cleaned out.
When the stove is cold, first look into the fire box and on the top you will see two screws, one in each plate. Loosen the screws using a screw driver. Once loose they can be pushed up and they will drop down. Then you can go to your cap and remove it. Pass your brush the entire length of your flue system. The junk will fall into the stove, some may go on the secondary combustion channel which you can just brush off, then scoop the junk out the stove.
Once clean you can place the cap back on. You can take the plates you removed and place them back as you found them. Tighten the screws enough to secure them in place and you can once again use your stove.
Once you determine your cleaning schedule of your particular set up, you should follow that schedule and clean the flue pipe regularly.
