NOTE:
Slope vent pipes a minimum of 1/4-in. per linear ft.
(20mm/meter) toward the Vent/Exhaust Pipe External Trap Kit with no
sags between hangers. DO NOT slope the vent pipes toward the furnace
when using the trap kit on the vent/exhaust piping system.
NOTE:
Slope the combustion-air inlet pipes a minimum of 1/4-in. per
linear ft. (20mm/meter) toward the exterior of the structure or insert a
second Trap Kit at the lowest point of the combustion-air inlet piping
system, within 24-in. (0.6 M) of the furnace.

and no more than 24-in. (0.6M) horizontally from where the vent exits
the furnace to achieve proper drainage.
