1. A combustion gas exhaust cap assembly for a combustion gas exhaust stack, the combustion gas exhaust cap assembly comprising:
an adapter section for mounting to the combustion gas exhaust stack, the adapter section having a primary combustion gas outlet that allows combustion gases from the combustion gas exhaust pipe to vent to the atmosphere and a secondary combustion gas outlet, the secondary combustion gas outlet directing combustion gas into a secondary process; and
a combustion gas exhaust cap mounted on the adapter section proximate the primary combustion gas outlet, the combustion gas exhaust cap being movable between an open position in which the combustion gas exhaust cap allows combustion gas to vent from the combustion gas exhaust pipe vent through the primary combustion gas outlet and a closed position in which the combustion gas exhaust cap covers the primary combustion gas outlet to seal off the primary combustion gas outlet, which diverts combustion gas from the combustion gas exhaust pipe through the secondary combustion gas outlet.
