that stove should be the same as my defiant. if you want to make sure that the secondary is running shut down the lights in the room and look into the secondary air inlet next to the side loading door and you should see a bright light from the fire ranging from yellow to i seen whitish blue. one thing i did in my defiant to help cushion the temp in the secondary camber was to slide in a brick in the hole on the right side of the stove where the secondary chamber is and sit it under the air manifold. on the defiant it fit perfect and it helped with secondary so much that i can interrupt the burn for more wood and close it down again for relight. and the brick helped keep the stove from turning red in a small spot on the side of the stove with the secondary fire.
