[Figure 1H-C. Modulating Burner Circuit Diagram]
1. Before connecting the motive power to the burner, ensure that the supply voltage is the same as the voltage on the burner nameplate.
2. Correctly connect the power phase and ground phase. (In the case of reverse wiring, there is a risk of explosion due to short circuit upon the burner start-up.)
3. The burner's ground terminal shall be securely connected to the actual ground.
