VENT CAPS
The Star-Kap
®
is the only vent cap that is not required to be two feet
higher than any structure within ten feet when used on detached or lean-to
buildings that house heating equipment outside of the living space.
The unique design of the aluminized steel Star-Kap Vent Cap prevents
downdrafts and assists the vent 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 vent stacks are designed to remove 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 vent stack and into the building. The Star-Kap prevents a
potentially dangerous situation.
PREVENT FLUE GAS SPILLAGE
The Star-Kap, when used in conjunction with a double-acting
Draft Control and Thermal Safety Switch, creates a system that
prevents flue gas spillage. Ask about AGA testing reports for
more information.
