INSTALLATION CONSIDERATIONS
solvent cemented to a length of pipe connecting the two
couplings. The length of pipe should be the wall thickness
plus the depth of the socket fittings to be installed on the
inside and outside of the wall. The wall penetration should
be sealed with silicone caulking material.

In a basement installation, the vent/flue pipe can be run be-
tween joist spaces. If the vent pipe must go below a joist
and then up into the last joist space to penetrate the header,
two 45° elbows should be used to reach the header rather
than two 90° elbows.
Direct Vent (Dual Pipe) Piping
Direct vent installations require both a combustion air in-
take and a vent/flue pipe. The pipes may be run horizontally
and exit through the side of the building or run vertically and
