7. Burner maintenance may be performed on all burner modules simultaneously or on each
one separately, as described in a) and b) below:
a) All Modules: Use a 13mm wrench to remove all “A” and “C” nuts (surrounded by
horizontal dotted lines in Figure 7-11, below). Leave the “ B” screws affixed so all
burner plates may be lifted together. Then complete the remainder of the instructions
in this section.
b) Separate Modules: Use a 13mm wrench to remove only the “A” and “C” nuts on
either side of the module in question (vertical dotted lines in figure 7-12), then
remove the “ B” Phillips screw at the end of the burner module. You can then skip the
remaining steps in this section and continue with section 11 - Cleaning the Burner
