DOOR GASKET REPLACEMENT (Cold Heater)
To replace deteriorated gaskets, following steps must be taken to ensure proper installation of gaskets.
1. Obtain proper gaskets and silicone glue from your local dealer.
2. Using pliers, remove any worn and deteriorated gaskets.
3. Using a scraper, wire brush and sandpaper or steel wool, clean glue and gasket residue from door frame.
4. Measure and cut gaskets to length. Care should be taken not to stretch gaskets. What you want is a full and
loose gasket weave after attachment to framing.
5.
Obtain silicone glue and run a 3/16” bead inside door frame.
6. Obtain gasket (s) and place in gasket channel areas. Use a technique which assures that gasket is applied in a
loose like manner. DO NOT STRETCH GASKETS.
7. After gasket (s) are applied to glue, use your finger and go over all gasket gently pressing gasket to the
channel. Use same pressure against gasket so that final result is an evenly applied gasket.
8. Leave door open and allow at least one hour for glue to dry.
9. Once gaskets are checked, heater is ready for use.
10. This should be done annually. Allowing gaskets to deteriorate can cause over-firing and shorten burn time.
