All installations and services must be performed by qualified service personnel.

F. INSTALLATION OF OUTSIDE VENT/AIR INTAKE TERMINATIONS

NOTICE: Installation of the outside exhaust and combustion air vents must be performed by a qualified installer or service person in accord with local codes, the National Fuel Gas Code (NFPA 54, ANSI Z223.1 or latest edition) and the sections on venting in this manual.

1.Observing all clearances specified in this manual, cut two 2-3/8” diameter holes in the outside wall for CHX1/CDX1-75 and two 3-1/2” diameter holes for the CHX1/CDX1-100 and 125.

2.Cut two 2” diameter PVC pipes 1-1/2” longer than the depth of the wall. This allows for 3/4” connection on both ends of the pipe. (For 3” PVC pipe, leave 3” for connection). Using PVC pipe cement, cement a PVC elbow or coupler to one end of each pipe.

Mark the pipe before inserting into the wall so the elbow orientation can be determined. Also, if a protective shield will be used on the exterior surface of the wall, it should be installed at this time. Glue a coupling or elbow to each pipe, depending on your installation with the PVC pipe cement being careful to maintain the proper orientation of the elbows. Complete the assembly of the outlet and inlet as shown in Figure 5, making sure that the spacing between the inlet and outlet complies with that shown in Figure 3.

3.Finish the vent installation by caulking around the two holes where the PVC pipes pass through the wall.

4.An optional vent or intake terminal (stainless steel) screen is available under part no. 320226.

Optional Terminations

Two optional vent kits are available for vent terminations on horizontal vent applications. The concentric vent kit (part no. 370171) allows for the vent and intake to be installed through one 4.5-inch diameter hole. The side wall vent cap (part no. 370191) is a cover to be installed over the vent and intake pipe as they exit the exterior of the building. These optional kits shall be installed according to the instructions provided with each kit. The locations and clearances are identical to the requirements of the standard vent terminations described in this manual. These vent kits may be used on any size of the CHX1/CDX1 furnace series.
