Common Questions:

Is this pilot assembly compatible with propane units?
No, the 100108775 is specifically engineered for natural gas (NG) configurations. Using this on a liquid propane system is unsafe and will result in improper combustion.

Does this kit include the necessary mounting hardware?
This kit typically includes the pilot assembly and the pilot tubing. It is designed to mount using existing burner door hardware or standard replacement clips often found in the heater's burner assembly.

Why is my pilot light failing to stay lit on my Lochinvar boiler?
Failing pilots are often caused by carbon buildup on the hood or a degraded sensor/thermocouple. Replacing the entire 100108775 assembly ensures all ignition components are refreshed for peak performance.
