Co-linear to Co-axial Combined Venting
IMPORTANT: Maximum horizontal vent runs of 24” (609mm) require
a 1” (25mm) rise per 12” (305mm) run. Care should be taken when
installing the flexible vent pipes to avoid a tight bend that may cause
abrasion or damage to the flexible pipes.
After the co-linear to co-axial vent adapter, the co-axial pipe requires
a minimum of 1” (25mm) clearance to combustibles on all sides of the
rigid pipe.
