Upright Drain Trap Mounting—Left or Right Side
1. Insert the drain tubes into the drain trap and position the
drain trap against the side panel.
NOTE: Drain tubes must reach the bottom of the drain trap.
2. Secure the drain trap to the side panel at the mounting holes
(dimples or crosshairs on counterflow models) located below
the grommet drain holes.
3. Attach the PVC drain line to the drain trap outlet with either a
90° elbow or coupling.
Horizontal Installations—Right Side Down
Horizontal installations with the right side down require that the
drain hoses be connected to the right side front cover drain port
and the rubber elbow drain port.
NOTE: On counterflow models, relocation of the front cover
pressure switch hose is required.
Make connections as follows:
1. Remove the rubber plug from the right side of the front cover
drain port.
NOTE: On counterflow furnaces, relocate the front cover
pressure switch hose connection from the left side pressure
tap to the right (down) side tap to guard against blocked drain
conditions. Cut the hose to appropriate length to minimize
sagging. Plug the left (unused) pressure tap with the plug
removed from right side.

right (down) side panel grommet holes.
11. Secure the tubes to Hose A and Hose B using the green hose
clamps.
NOTE: Ensure that the hoses and tubes maintain a
downward slope for proper drainage and are not kinked or
bound.
