Common Questions

Is the 1190850 "Brute Pilot" the same as the "Long Pilot"?
No. While they look similar, the 1190850 Brute Pilot is distinct from the 1190100 Long Pilot and 1190800 Short Pilot. Always verify your specific Midco burner model to ensure you have the correct length for proper ignition overlap.

What is the recommended spark gap for this assembly?
For optimal ignition reliability, ensure the spark gap between the electrode and the pilot shroud is set between 1/8" and 9/64". Using a drill index or pocket screwdriver as a feeler gauge is a common field practice for this adjustment.

Does this assembly include the gaskets?
Yes, this OEM replacement kit typicaly includes the necessary hardware and rubber seals. However, when replacing the pilot box, always inspect the white fiber gaskets to ensure a gas-tight seal against the burner manifold.
