Because in addition to this small piece will cause disruption, there is no other blocking factors. It is unlikely, because the hose folded into 90 degrees into the shed, the naked eye can not see it. But you can use wire to touch it, and if you can push it open, you can try again. However, it is estimated that the shed is still of little significance.The kitchen ceiling is usually plastic buckle or aluminum pinch plate, demolition does not cost anything.It is a reminder: remove the check valve, hose in the crossing installation process should be carefully done, it is best to buy a duct flange, glass sealant with a circle, and then buckle in the flue, the hose into the flange, carefully wrapped with tape, confirmed that no leakage shall prevail this is because, in the shed, and then deal with trouble ah.If the check valve is well connected with the flue port, it is possible to remove the check plate (plate) and make it easier to use the original chassis.
