Different installations may require slightly different orientations. The following steps apply to all installations. 2. The Tee Trap should be installed as close to the side or top of the furnace as practical. Minimize the distance between the inducer and the Tee Trap as much as possible. 3. An open tee is to be used at the Tee Trap discharge. The top end of the tee should be open to the atmosphere to eliminate potential air lock problems. 4. The drain line from the Tee Trap is to be connected to the furnace condensate trap drain line as shown above. 5. Condensate drain lines from a cooling coil may be connected downstream of the connection point of the Tee Trap and Furnace Condensate Trap. Important: Prime both traps with water before operation. Failure to prime the traps may result in discharge of flue gases from the condensate drain line and open tee for a period of time, and may result in temporary lockout of the furnace upon start up. Main drain line construction is left to the discretion of the installer. It may be made of either ridged pipe or flexible tube. Tube ID should NOT be less than 1/2,,. 44001 102004 EB Condensate Trap ,m o o_ / 25-24-41N Connecting Vent and Combustion Air Piping CARBON MONOXIDE POISONING HAZARD Failure to properly seal vent piping could result in death, personal injury and/or property damage. Cement or mechanically seal alljoints, fittings, etc. to prevent leakage of flue gases. Refer to Figure 9 through Figure 17 that corresponds to the installation position of the furnace for the application. Preassemble the vent and combustion air piping from the furnace to the vent termination. Do not cement the pipe joints until the pipe preassembly process is complete. Combustion Air Pipe Connection (Dual Certified or Direct Vent) Install the air intake coupling and gasket to the furnace with the four(4) screws. Note: The air intake cou piing and gasket ca n be installed to the top panel to the alternate air intake locations on either the left or right side panels of the furnace. For downflow installation, the air intake coupling and gasket must be installed to the alternate air intake location on either the left or right side panels. Remove the 3" hole plug from the side panel and relocate to the air intake hole in the top panel. Use four screws to seal the four(4) mounting holes in the top panel next to the hole plug. Drill four(4) 7/64" diameter holes in the casing using the air intake coupling as the template. [!N The air intake coupling is sized for 2" PVC pipe. Install the combustion air pipe to the air intake coupling using RTV sealant to provide for future serviceability. Vent Pipe Connection Install the vent pipe grommet to the furnace panel. Locate the grommet in the furnace panel at a location directly away from the vent fitting on the combustion blower. The grommet snaps into the 3" hole plug from the furnace panel. NOTE: Depending on the installation position, the vent pipe grommet will be installed to the top panel or to the alternate location on the side panels. If needed, remove the 3" hole plug from the furnace panel and relocate to the open hole in the furnace panel. (See Figure 9 or Figure 18) Install the vent pipe to the rubber coupling, the vent fitting or the PVC...
