accordance with all local codes and the instructions in the follow- ing sections.
Follow the bullets listed below when installing the drain system. Refer to the following sections for specific details concerning fur- nace drain trap installation and drain hose hook ups.
•The drain trap supplied with the furnace must be used.
•The drain line between furnace and drain location must be constructed of 3/4” PVC or CPVC.
•The drain line between furnace and drain location must maintain a 1/4 inch per foot downward slope toward the drain.
•Do not trap the drain line in any other location than at the drain trap supplied with the furnace.
•Do not route the drain line outside where it may freeze.
•If the drain line is routed through an area which may see temperatures near or below freezing, precautions must be taken to prevent condensate from freezing within the drain line.
•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.
UPRIGHT INSTALLATIONS
In an 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 or left side panel and into the drain trap secured to the outside of the cabinet.
NOTE: Refer to Section X, Condensate Drain Lines and Drain Trap
-Alternate Vent/Flue Hose Connections for upright installations using an alternate vent/flue outlet.
STANDARD RIGHT OR LEFT SIDE DRAIN HOSE CONNECTIONS

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 red hose clamp. Angle tube outward toward front of furnace.
5.Right side drains
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.
Left side drains
Cut “X” inches from the long end of Hose B and discard. Refer to table for appropriate length to cut. Secure remaining hose to Tube 1 with a green hose clamp. Route other end of Hose B to front left side panel grommet hole.
