SAFEGUARD THE FINAL STEP OF THE VENT PATH

Whether venting through a chimney or a sidewall, every combustion system needs a secure, properly designed termination point. Termination caps are essential for preventing downdrafts, keeping out debris, and maintaining proper draft pressure.
Field Controls offers a complete range of vertical and horizontal vent terminations built for gas, oil, and power vented systems. These components are engineered for weather resistance, easy installation, and code-compliant performance, helping ensure combustion systems operate safely and reliably, all year long.
WHY TERMINATION MATTERS
Prevents Downdrafts
Proper cap design minimizes wind interference that can push exhaust gases back into the venting system.
Keeps Out Debris and Critters
Screens or hoods block birds, rodents, leaves, and rain from entering the flue.
Supports Consistent Draft
Maintains outlet velocity and reduces turbulence to help ensure steady exhaust flow.
Meets Code Requirements
Terminations are designed to comply with clearances, spacing, and protection requirements under NFPA and local building codes.


HOW IT WORKS
Termination caps are installed at the outermost end of the venting system on rooftops, vertical stacks, or horizontal sidewall runs. Depending on the fuel type and venting configuration, caps may include wind guards, spark arrestors, screens, or deflectors to manage airflow and improve system stability.
