Figure 26. See Figure 31. For Canadian applications
ONLY: IPEX 196006 may be used for horizontal and
vertical terminations. IPEX 081216, IPEX 081218, and
IPEX 081219 may only be used for horizontal vent
terminations.

CAUTION
!
When the vent pipe is exposed to temperatures below
freezing, i.e., when it passes through unheated spaces,
etc., the pipe must be insulated with 1/2 inch (22.7
mm) thick Armaflex-type insulation or equal. If the
space is heated sufficiently to prevent freezing, then
the insulation would not be required. If domestic water
pipes are not protected from freezing then the space
meets the condition of a heated space.
VENTING THROUGH THE ROOF
When penetrating roof with a 2" PVC Vent Pipe, a 2"
electrical conduit 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 as shown in Figure 35 is the preferred
method for vertical Vent Termination in extremely cold
climates.
In extreme climate conditions, insulate the exposed
pipe above the roof line with Armaflex type insulation.
