Flame burner ignition system

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 secondary winding coupled to an electrically isolated neutral conductor, 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;
• connecting the second input of the ignition module to the ground conductor;
• and
• creating a return path for passing a current via a flame output from the burner and via the ground conductor to the electrically isolated neutral conductor.

An ignition system comprising:

• a burner for producing a flame;
• a power supply;
• an electrical system comprising a ground conductor coupled to said burner;
• an ignition module comprising a first input, a second input, and a single output, said output operatively coupled to said burner, one of said inputs coupled to said ground conductor, the other of said inputs coupled to said power supply;
• an isolation transformer connected in series between said power supply and said ignition module;
• an electrically isolated neutral conductor coupled to said ignition module and said isolation transformer;
• wherein said ground conductor configured to provide a return path that passes a current from a flame output from said burner to said electrically isolated neutral conductor.

An ignition system comprising:

• a gas burner;
• an AC power supply comprising a phase conductor and neutral conductor;
• an electrical system comprising a ground conductor coupled to said burner;
• an isolated neutral conductor;
• an isolation transformer comprising a primary winding and a secondary winding, said primary winding connected to said phase conductor and to said neutral conductor, said secondary winding coupled to an isolated phase conductor and said isolated neutral conductor;
• and
• an ignition module comprising a first input, a second input, and an output, said output electrically connected to an igniter, said ignition module coupled in series with said isolation transformer, wherein one of said inputs coupled to said isolated neutral conductor, the other of said inputs coupled to said isolated phase conductor, said ground conductor coupled to said isolated neutral conductor between said ignition module and said isolation transformer, and said ground conductor configured to provide a return path that passes a current from a flame output from said burner to said isolated neutral conductor.
