Saf-T Vent CI Plus Tall Cone Flashing with Rain Cap In Combustible Chase:
Figure 2
Figure 1
APPLICATION 1. Directly On Flat Roof (figures 1 & 2).
Prepare a square or round opening 4 1/2" larger than the inner vent pipe diameter, i.e. an 8" inner vent
would have a 12 1/2" opening. Apply weather-stripping or outdoor caulk to the bottom of the cone plate.
Attach the cone to the roof using common construction methods. Flash over the cone plate and seal
the fastener heads using normal roofing requirements. When the vent pipe is in place through the Tall
Cone, attach the Tall Cone storm collar around the pipe and position at least 2" above the top edge of
the cone (figure 1). This 2" air space will release any built up heat from inside the cone. Apply RTV
sealant around the top of the storm collar and the pipe. On the last section of pipe before the Rain Cap,
install the Ventilation Collar over the air space between the inner and outer vent pipes. Install the Rain
Cap on the last section of vent per the Rain Cap installation instructions. Position the Rain Cap Storm
Collar 2" above the Ventilation Collar as shown in Figures 1 & 3. When the Tall Cone is used as a
vertical support, screw the self-tapping screws through the holes in the cone and into the wall of the
Outer Vent.
CAUTION: Support screws can only be installed with Saf-T Vent CI Plus venting.
