5.1.5 Replacing the door gasket

It is important to maintain the gaskets in good condition. After a year or more of use, the door gaskets will
compress and become hard, which may allow air to leak past it. You can test the condition of the door
gaskets 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 gaskets.
Use the correct replacement gasket: (A) for the doors and (H) for the doors junction. Both can be purchased
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
gaskets 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 1/4" (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 1/2" 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
fireplace for 24 hours.
