The Field Control Star-Kap roof vent cap prevent downdrafts and assists the vent in drawing off and exhausting waste gases regardless of wind direction.

WHEN DO YOU USE A STAR KAP ROOF VENT CAP?

  • To prevent downdrafts.
  • To keep birds and debris out of the vent stack.
  • To keep rain out of the vent stack.
  • When venting gas or oil appliances.

The Star-Kap is the only roof vent cap that is not required to be two feet higher than any structure within ten feet. The unique design of the aluminized Star-Kap Roof Vent Cap prevents downdrafts and assists the chimney in drawing off and exhausting waste gases regardless of wind direction. The Star-Kap can be used to vent gas or oil fired boilers, furnaces, water heaters and more. Although chimneys are designed to vent off dangerous gases and smoke created by burning gas and oil, this process can be adversely affected by the direction of the wind. A sudden gust could blow noxious waste gases down the chimney and into the building. The Field Controls Star-Kap prevents a potentially dangerous situation. HOW DO YOU PREVENT FLUE GAS SPILLAGE? The Star-Kap roof vent caps, when used in conjunction with a double-acting Draft Control and Thermal Safety Switch, creates a system that prevents flue gas spillage and carbon monoxide formation.
