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 8-11, 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 8-11), 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 8-11 - Cleaning the Burner Module.
