Brass Plug for Autopilot CO2 Generators

Seal Unused Burner Outlets on Your Autopilot CO2 Generator

When running an Autopilot CO2 generator with fewer than its maximum number of active burners — or after removing a failed burner before a replacement arrives — unused burner outlets must be sealed to prevent gas leakage and ensure safe, complete combustion from the active burners.

The Autopilot brass plug is the correct sealing component for this purpose. Its brass construction provides a durable, reliable seal that is compatible with both LP (propane) and NG (natural gas) Autopilot CO2 generator models.

Key Features & Benefits

• Seals unused burner outlets — prevents gas leakage from open outlets when running fewer active burners than the generator's capacity.
• Compatible with LP and NG generators — works with both liquid propane and natural gas Autopilot CO2 generator models.
• Brass construction — provides corrosion resistance and a secure, reliable seal at the burner outlet connection.
• Required when reducing active burners — any outlet that is not fitted with an active burner must be sealed with this plug — start from the back row and work forward.

Who Should Use the Autopilot CO2 Generator Brass Plug

Growers running Autopilot CO2 generators with fewer active burners than the generator's capacity — either intentionally or while awaiting a replacement burner — who need to seal the unused outlets safely.

Correct Order for Sealing Outlets

When reducing the number of active burners, start plugging from the back row and work forward toward the front. This order ensures that active burners are in the front positions where air flow and ignition are optimal for complete combustion.

Frequently Asked Questions

Do I need to plug unused burner outlets on my Autopilot CO2 generator?

Yes — all outlets not fitted with an active burner must be sealed with a brass plug to prevent gas leakage and ensure safe operation. Running the generator with open, inactive outlets is a safety hazard.

Does the plug fit both LP and NG generator models?

Yes — the brass plug is compatible with both liquid propane and natural gas Autopilot CO2 generator models.

In what order should I plug unused outlets?

Start from the back row and work forward. This places active burners in the front positions, which is optimal for air flow and complete combustion.

Can I permanently reduce the number of active burners on my generator?

Yes — plug the unused outlets with brass plugs and operate only the active burners. The generator will produce proportionally less CO2 output, which may be appropriate for smaller rooms or lower CO2 demand.
