Abstract

An ignition system includes a burner, a power supply, an electrical system including a ground conductor, and an ignition module. The ignition module includes a first input, a second input, and an output. The output is operatively coupled to the burner, while one of the inputs is coupled to said ground conductor, and the other of the inputs is coupled to the power supply.

Claims

1. A method for installing an ignition module for a flame burner to an electrical system, the electrical system including a phase conductor, a neutral conductor and a ground conductor, the burner connected to the ground conductor, the ignition module including first and second inputs and at least one output, said method comprising:

connecting the phase conductor to the first input of the ignition module; and

connecting the ground conductor to the second input of the ignition module.

2. A method in accordance with claim 1, the electrical system including a junction box, said method further comprising connecting an isolation transformer between said junction box and said ignition module.

3. A method in accordance with claim 2 wherein the transformer includes a secondary winding, said method further comprising connecting the secondary winding to the first input of the ignition module and to the ground conductor.

4. A method in accordance with claim 3, the transformer including a primary winding, said method further comprising connecting the primary winding to the phase conductor and the neutral conductor.

5. A method for installing an ignition module for a gas-fired burner to an isolation transformer of an electrical system, the isolation transformer including a primary winding and a secondary winding, the electrical system including a phase conductor, a neutral conductor and a ground conductor, the burner connected to the ground conductor, the ignition module including first and second inputs and at least one output, said method comprising:

connecting the transformer secondary winding to the first input of the ignition module;

connecting the transformer secondary winding to the ground conductor; and

connecting the second input of the ignition module to the ground conductor.

6. A method in accordance with claim 5 further comprising connecting the primary winding to the phase conductor and the neutral conductor.

7. An ignition system comprising:

a burner for producing a flame;

a power supply;
