The Tee Trap must be connected to the main condensate drain

line as conceptually shown above. Different installations may

require slightly different orientations. The following steps apply to all installations.

Connecting Vent and Combustion Air Piping

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 elimi- nate 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.

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.

5.Condensate drain lines from a cooling coil may be con- nected 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,,.

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.
