5.1.5 Replacing the Door Gasket
It is important to maintain the gasket in good condition. After a year or more of use, the door gasket will
compress and become hard, which may allow air to leak past it. You can test the condition of the door
gasket by closing and latching the door on a strip of paper. Test all around the door. If the paper slips out
easily anywhere, it is time to replace the gasket.
Use the correct replacement gasket that you can purchase from your retailer. The diameter and density of
the gasket is important to getting a good seal.
Place the door face-down on something soft like a cushion of rags or piece of carpet. Remove the old gasket
from the door by pulling and prying it out with an old screw driver. Then use the screwdriver to scrape the
old gasket adhesive from the door. Now run a 6 mm bead of high temperature silicone in the door gasket
groove. Starting from the middle of the hinge side, press the gasket into the groove. Do not stretch the
gasket as you place it. Leave the gasket about 12 mm long when you cut it and press the end into the
groove. Tuck any loose fibres under the gasket and into the silicone. Close the door and do not use the zero
clearance wood inbuilt for 24 hours.
