DOUBLE WALL:
1. Align pipes and push them together until the snap-lock
engages. (Illustration #1A, Images 4, 5 & 6).
Proper pipe orientation is essential to achieve effective
condensate flow. In most cases the use of an appliance
specific flue collar adaptor is required to connect directly to
the appliance. This adaptor will configure the vent orientation
with the gasket end of pipe and fittings towards termination.
Also:
Some flue collars may require the use of high temperature
silicone sealant to make a positive pressure gas tight seal.
