The RF000142 coupling (Figure 9) can be secured
directly to the furnace intake coupling if condensation/
rain water is a concern. If the RF000142 is used on the
combustion air inlet, it must be installed with the arrow
pointing up. It should be noted, the combustion air will
actually be moving in a direction opposite of the arrow
on the RF000142 coupling. It must have a eld supplied,
trapped drain tube free-draining to a proper condensate
disposal location. A loop in the drain tube can serve as a
trap. The unused RF000142 drain tting must be capped.
A eld supplied tee installed in the intake pipe is also an
acceptable method of catching condensation. It must have
a eld supplied, trapped drain tube or pipe, free-draining to
a proper condensate disposal location. A loop in the drain
tube can serve as a trap.

When installing a furnace horizontally with the left side
down, alternate ue and combustion air pipe connections
may be used. This method allows the ue and combustion
air piping to be run vertically through the side of the
furnace (facing up in horizontal left). The alternate vent
location is the 3” hole directly in line with the induced draft
blower outlet.
When using the horizontal alternate vent conguration,
you must use the RF000142 vent drain kit. See Figures
8-11 & follow steps below.
