1.Turn off service switch on boiler control panel.
2.Remove boiler front door by removing the two knurled screws at the bottom with a flat blade screwdriver. Once the knurled screws are removed, lift the front door off the boiler.
3.Remove the existing gasket and adhesive from the top, bottom, and sides of the front door.
4.Clean the edges of the boiler in the locations of the new gasket as shown in Figure 1. Isopropyl Alcohol may be used to remove any oil or residue. Allow the surfaces time to dry before continuing to the next step.
NOTICE
Do not stretch gaskets when applying them to the boiler. Simply press the gasket firmly into place to allow the adhesive to make contact with the boiler.
When applying the gasket only remove plastic backing to expose the adhesive as needed. This will make the gasket easier to handle. Minimize gaps between sections of gaskets and trim any excess length.
