Is this burner assembly compatible with propane units?
No, the 100110753 is designed strictly for natural gas water heater applications. Propane units require different orifice sizing and pressure ratings; using this component with LP gas is unsafe and will lead to system failure.

When should I replace the entire burner assembly instead of just the pilot?
If you notice heavy corrosion on the burner plate, clogged ports that cannot be cleared, or persistent yellow tipping that isn't resolved by cleaning, a full burner assembly replacement is necessary to ensure safety and code compliance.

Does this kit include the orifice?
Yes, this assembly comes standard with the #32 orifice already installed, tailored for specific Lochinvar and A.O. Smith natural gas manifolds.
