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 that you can purchase from your retailer (see table below).
The diameter and density of the gasket is important to getting a good seal.
Place the doors 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 frame gasket (A) groove of the door gasket. 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. Do the same for center door gaskets (B).
Repeat for other door. Close the door and do not use the fireplace for 24 hours.
