FUEL SELECTOR SWITCH (COMBINATION UNITS ONLY)
This switch is located in the lower right-hand corner of the panel box. It is used to determine the
type of fuel for the burner. If both fuel supplies are connected, all that is required to change fuel
types is to flip the switch. If both fuel supplies are not connected, refer to SECTION 5: BURNER
OPERATION for the proper start-up procedure. If switching from gas to oil, make sure the fuel oil
pump coupling is connected. Also note that this is a three-position switch. Make sure that it is
not in the neutral position.
