When penetrating roof with PVC vent pipe, a flexible flashing may be
used for a weather tight seal. Lubricate flexible seal on flashing before
PVC pipe is pushed through the seal. (Field Supplied)
Note: No vent cap is the preferred method for vertical vent
termination in extremely cold climates.
Note: In extreme climate conditions, insulate the exposed pipe above
the roof line with Armaflex type insulation.
