UPRIGHT DRAIN TRAP MOUNTING (LEFT OR RIGHT SIDE PANEL)
1.Insert drain tubes into drain trap and position the drain trap against the side panel. NOTE: Drain tubes must reach the bottom of the drain trap.
2.Secure drain trap to side panel at the mounting holes (dimples or crosshairs on counterflow models) located below the grommet drain holes.
3.Attach PVC drain line to 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 right side of the front cover drain port.
Counterflow furnaces
Relocate the front cover pressure switch hose connection from the left side pressure tap to the right (down) side tap. The pressure switch hose must be connected to the down side to guard against blocked drain conditions. Cut hose to appropriate length to minimize sagging. Plug left (unused) pressure tap with plug removed from right side.
2.Secure Hose A to front cover drain tap with a red hose clamp. Route hose to rear right (down) side panel grommet holes.
3.Cut 1/4 inch from the end of the drain port on the rubber elbow and discard.
4.Insert Tube 1 into rubber elbow drain port and secure with a silver hose clamp. Angle tube outward toward front of furnace.
5.Cut 17 3/4 inches from the long end of Hose B and discard.
6.Secure remaining end of Hose B to exposed end of Tube 1 with a green hose clamp. Route hose to front right down side panel grommet holes.
7.Cut 5 1/2 inches straight length from the long end of each Tube 2 and discard the radius pieces.
8.Insert approximately one inch of each Tube 2 through the right down side panel grommet holes. Secure tubes to Hose A and Hose B using green hose clamps. Ensure hoses and tubes maintain a downward slope for proper drainage and are not kinked or bound.
For details concerning mounting of the drain trap, refer to Conden- sate Drain Lines and Drain Trap - Horizontal Drain Trap Mounting.
