Installation

Kozy Kollar products are the only roof vent boot/flashing or exhaust hood you install from inside a building and over shingles or similar roofing materials. Patented and proven, both systems form a weathertight seal for vent pipe penetrations and utilizes three independent gasket systems which are designed to work in conjunction with each other to keep out the elements and you off the roof.

Step One: After selecting an area to install from inside the building, square the template between the roof rafters and outline with a marker. Using a sawzall, cut any roofing nails in the area of the lower mounting plate flush with the sheathing. Next, use a reciprocating saw with a rough-in blade to cut the out the marked template. The downward pull of the blade will cut the shingles cleanly. Do not cut outside the line.

Step Two: Install four of the six threaded studs and apply a thin bead of the sealant supplied with the Kozy Kollar or EV-4 into the caulking channel of the primary seal. Pass the Kozy Kollar or EV-4 through the opening and position it on the shingles. The four corner studs will hold the Kollar or EV-4 in place.

Step Three: Install the remaining studs, the lower mounting plates, and rod couplings. The Kozy Kollar and EV-4 require compression to work. Starting with the top studs, tighten the rod couplings to approximately 3 ft. lbs. If a torque wrench is not available, tighten the rod couplings until the lower mounting plates begin to distort.
