    2. Theory of Operation 2.1 DTHS-2 Models: 40,000 BTU/H through 100,000 BTU/H • Starting Circuit (Figure 2.1) When voltage is applied to L1 and L2, a circuit is completed from L1 via the blower motor to L2. The blower fan is mounted in the control box and rated to supply sufficient air combustion. Air pressure generated by the blower will cause the normally open burner pressure switch No.
  • Page 5: Dths-3 Wiring Diagram & Theory Of Operation

    Theory of Operation 2.2 DTHS-3 Models: 125,000 BTU/H and 150,000 BTU/H • Starting Circuit (Figure 2.2) When voltage is applied to L1 and L2, a circuit is completed from L1 via the blower motor to L2. The blower fan is mounted in the control box and rated to supply sufficient air for combustion. Air pressure generated by the blower will cause the normally-open burner pressure switch No.
