A heating apparatus for a heat exchanger system includes a manifold having a plurality of burners, a shutoff valve, a first controller and a second controller. The shutoff valve divides the manifold into a first manifold portion and a second manifold portion. The first controller selectively controls the communication of a fluid within the manifold. The second controller selectively actuates the shutoff valve between a first position and a second position to control a firing rate of the plurality of burners.

1. A heat exchanger system, comprising: a gas valve;a manifold in fluid communication with said gas valve;a shutoff valve positioned downstream from said gas valve and dividing said manifold into a first manifold portion and a second manifold portion;a plurality of burners positioned adjacent to said manifold, wherein a first amount of said plurality of burners are positioned upstream from said shutoff valve within said first manifold portion and a second amount of said plurality of burners are positioned downstream of said shutoff valve within said second manifold portion;a first controller that selectively communicates with said first amount of said plurality of burners; anda second controller that selectively communicates with said second amount of said plurality of burners. 2. The system as recited in claim 1, comprising a thermostat operable to selectively communicate a control signal to each of said gas valve, said first controller and said second controller. 3. The system as recited in claim 1, comprising a thermostat system having a first thermostat, a second thermostat and a relay, wherein said thermostat system is operable to selectively communicate control signals to each of said gas valve, said first controller and said second controller. 4. The system as recited in claim 1, comprising at least one spark electrode and at least one flame sensor associated with said plurality of burners. 5. The system as recited in claim 1, wherein a first spark electrode and a first flame sensor are associated with said first amount of said plurality of burners and a second spark electrode and a second flame sensor are associated with said second amount of said plurality of burners. 6. The system as recited in claim 5, wherein said first controller controls said first spark electrode and said first flame sensor and said second controller controls said second spark electrode and said second flame sensor. 7. The system as recited in claim 1, wherein said second controller selectively actuates said shutoff valve between a first position and a second position to control a firing rate of said plurality of burners. 8. The system as recited in claim 7, wherein said first position is a closed position and said second position is an open position, and said fluid is blocked from said second amount of said plurality of burners in response to said shutoff valve being positioned at said first position.
