•If an air conditioning coil is installed with the furnace, a common drain may be used. An open tee must be installed in the drain line, near the cooling coil, to relieve positive air pressure from the coil’s plenum. This is necessary to prohibit any interference with the function of the furnace’s drain trap.
NOTE: In vertical installations, air conditioning coil condensate may drain into the furnace trap as long as there is a trap between the coil and the furnace trap and the drain pipe is not terminating below the water level of the furnace trap.
STANDARD RIGHT OR LEFT SIDE DRAIN HOSE CONNECTIONS
All installations positions require the use of the drain trap, hoses, tubes, and clamps. The following quantity of hoses, tubes, and hose clamps are provided with the unit.

Hose and Tube Identification
In a upright installation drain hoses are connected to drain ports on the rubber elbow and the recuperator coil front cover. The drain lines are then routed through the right side panel and into the drain trap secured to the outside of the cabinet.
NOTE: Refer to Alternate Vent/Flue Hose Connections for upright installations using an alternate vent/flue outlet.
1.Remove the rubber plug from the right side of the front cover drain port.
2.Secure Hose A to front cover drain port with a red hose clamp. Route hose to rear side panel grommet hole.
3.Cut and remove 1/4 inch from the end of the drain port on the rubber elbow.
4.Insert Tube 1 into rubber elbow drain port and secure with 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. Secure the remaining hose to Tube 1 with a green hose clamp. Route the other end of Hose B to front right side panel grommet hole.
For details concerning mounting of the drain trap, refer to Vertical Drain Trap Mounting.
6.Insert short end of each of tube 2 through side panel grommet holes. Secure tubes to hoses A and B with green hose clamps. Ensure hoses and tubes maintain a downward slope for proper drainage and that they are not kinked or binding.
