9.3.2 Removing The Burner Modules
To remove the burner modules and gaskets, refer to the instructions, below.
NOTE
Before removing the burners and gaskets, verify if the gaskets have
been glued to the aluminum surface. If they have, apply an appropriate
solvent and let set for the recommended time before attempting to
remove the gaskets.
Removing Burner Module(s)
1. If present, remove all the grounding tabs (Figure 9-12) at the rear of the burner modules (one per
burner and screwed onto the boiler body) and discard. These are no longer needed as the new
replacement gaskets are self-grounding. Use only the newer style gaskets as replacements.
Ensure that the small plaited copper grounding used on OLD gaskets is
completely removed along with old gaskets from the burner mounting
surfaces.
2. Remove each burner module from its seat by inserting a cutter between the gasket and the aluminum
body on which it rests, and then carefully running the cutter down three sides of the burner. The
photos in Figure 9-13 show the (1) cutter being run along the shorter front edge, (2) along right long
edge, and (3) along left long edge.
3. Next, remove the burner by carefully rotating it upward ONLY along the left or right long edge axis (#4
in Figure 9-13). Take care to avoid deforming the burner module as it is removed.

NOTE
Old style gaskets are orange. Newer style gaskets are grey.
