Upright “Alternate” Connections - Right Side Only

“right-side only” drain hoses to be connected as follows. Refer to Section IX, Vent/Flue Pipe and Combustion Air Pipe for details on alternate vent/flue pipe connection.

1.Remove the rubber plug from the front cover right-side drain port. Save for use in step 3.

2.Secure Hose A to front cover drain port with a red hose clamp. Route hose to rear right side panel grommet hole.

3.Remove grommet from front right-side panel drain hole. Seal hole in grommet with large end of plug. Reinstall grommet and plug into side panel drain hole.

4.Cut 1/4 inch from the end of the drain port on the externally mounted rubber elbow. Discard cut portion.

5.Insert Tube 1 into rubber elbow drain port and secure with a red hose clamp. Angle tube outward toward front of furnace.

6.Cut 17 7/8 inches from the long end of Hose B and discard.

7.Secure remaining end of Hose B to exposed end of Tube 1 with a green hose clamp. Route hose toward right side panel grommet holes.

8.Insert short end of one Tube 2 through rear right side panel grommet drain hole. Secure tube to Hose A with a green hose clamp.

9.Insert short end of remaining Tube 2 into Hose B from rubber elbow and secure with green hose clamp. Ensure hoses and tubes maintain a downward slope for proper drainage and are not kinked or binding.

Upright “Alternate” Connections - Right Side Only

(Upflow Shown, Counterflow Similar)

For details concerning mounting of the drain trap, refer to the fol- lowing section.

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 the coil 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 red 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.

Horizontal Connections - Right Side Down

(Upflow Shown, Counterflow Similar)

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 Section X, Condensate Drain Lines and Drain Trap - Upright Drain Trap Mounting.

LEFT SIDE DOWN

Horizontal installations with the left side panel down will require drain hoses to be connected to the left side front cover drain port and the side drain port on the rubber elbow.

1.Remove the rubber plug from the coil front cover left (down) side drain port.

2.Relocate the front cover pressure switch hose connection from the right side (as shipped) pressure tap to the left (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 right (unused) pressure tap with plug removed from left side.

3.Secure Hose A to front cover drain port with a red hose clamp. Route hose to rear left (down) side panel grommet holes. NOTE: For left side drainage, grommets must be relocated to left side panel.
