CAP System Kit

Combustion Air Proving Kit (with Burner Cut-Off)

The Carlin CAP (Combustion Air Proving) System — A Superior Solution for Meeting Combustion Air Code Requirements.

Why fill a homeowner’s basement with cold air in the winter and humid air in the summer? When dealing with combustion air or confined space limitations, the CAP System is a superior solution!

By providing direct combustion air to your appliance and allowing you to reduce the area considered “confined” for ventilation by 50%, the CAP System makes dealing with confined space installations a breeze!

The CAP System provides direct combustion air to the appliance, is simple to install and ensures safe operation by cutting off burner when a blockage is detected.

The Carlin CAP System provides code compliant piece of mind!

• Easily Installed
Building Code Compliant*
• Preferred by Homeowners

*Designed to meet NFPA31, section 5.4.3.3, as covered by April 2019 TIA 16-2
