Double-sealed high-temperature resistant DC ignitor for use with wood pellet burner assemblies

A high-temperature resistant direct current (DC) ignitor for use with a wood pellet burner assembly, comprising:

• a non-heating element portion, wherein the non-heating element portion is connected to at least one of a battery or an alternating current (AC) to DC electrical transformer attached to the wood pellet burner assembly;
• a heating element portion connected to the non-heating element portion, and configured to extend into a combustion region of the wood pellet burner assembly, wherein the heating element portion is configured to be heated by power received from the at least one of the battery or the AC to DC electrical transformer;
• an outer housing surrounding a mid section of an ignitor housing;
• a plurality of threads disposed in the outer housing;
• and
• a plurality of set screws disposed in the corresponding plurality of threads, and configured to hold the ignitor housing within the outer housing without the ignitor housing directly touching inner walls of the outer housing,
• wherein:
• the heating element portion is configured to extend through a pellet fuel slide of the wood pellet burner assembly;
• the DC ignitor is disposed in a substantially horizontal orientation;
• the wood pellet burner assembly includes a DC fan positioned to direct a flow of air in a substantially horizontal direction along the length of the DC ignitor, through perforations in the pellet fuel slide and into the combustion region;
• the AC to DC electrical transformer is configured to power the DC ignitor and the DC fan;
• the wood pellet burner assembly includes a body grounding lug, a user operable power switch, and a user-operable ignitor switch in communication between the AC to DC electrical transformer and the DC ignitor;
• and
• wherein the non-heating element portion is connected to the at least one of the battery or the AC to DC electrical transformer via the user-operable ignitor switch.
