WARNING
ALWAYS properly cut the pipe at a 90° angle and

Use water (NOT grease) to lubricate the end of
the vent pipe before inserting into the Common
Vent Collar.
ALWAYS insert the vent pipe 1.5 in (38 mm) into
the Common Vent Collar using a twisting motion
until the end reaches the bottom of the socket.
If flue gas leaks, inhalation of carbon monoxide
