service switch should be mounted on the side of the boiler so the burner man can service the burner
and controls. The electrical wiring should be routed so as not to interfere with normal servicing of the
boiler. Wiring done in the field between devices not attached to boiler shall conform with the
temperature limitations for type T wire (63F/35C) or other specified wire as applicable when installed
in accordance to manufacturer's
instructions and wiring diagrams.
