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. In some cases a clamping mechanism may be necessary to 
secure the adaptor to the appliance.
