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

2.Measure and cut two (2), 2-inch diameter thermoplastic pipes 1-1/2 inches longer than the depth of the wall. (Cutting the pipe longer leaves a ¾ inch connection allowance at both ends of the pipe.) For 3-inch diameter PVC pipe, leave a 3-inch allowance for end connections. Using PVC pipe cement, glue a PVC elbow or coupling fitting to one (1) end of each pipe.

Before inserting the pipe through the wall, mark the other end of the pipe so the elbow orientation can be determined. Also, if a protective shield (refer to Section E., passage 1. of this manual) will be used on the exterior surface of the wall, it should be installed at this time. From the inside, glue a coupling fitting to each pipe, using PVC pipe cement, while being careful to maintain the proper orientation of the termination elbow(s). 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 noted in Figure 3.

3.Finish the vent installation by caulking the annulus to seal around the two (2) holes where the thermoplastic pipes pass through the wall.

4.To prevent foreign material, insects, or small animals from entering the pipes, an optional vent or intake terminal (stainless steel) screen is available from Thermo Products under part no. 320226 for 3” vent and 320219 for 2” vent.

5.Optional Direct Vent Terminations

Three optional vent kits are available for direct vent terminations, refer to Figure 6.

•The concentric vent kits (Thermo Products p/n AOPS7488 & AOPS7489) provide a means for the vent and intake to be installed through a single opening in the roof or exterior wall. Kit p/n AOPS7488 requires a 4” inch diameter hole and is used on furnace models CHB1/CDB1-50 & 75. Kit p/n AOPS7489 requires a 5” inch diameter hole and is used on furnace models CHB1/CDB1-100 &125.

•The sidewall vent cap (Thermo Products part no. 370191) is a cover installed over the exhaust vent and air intake pipes on the exterior of the building. For horizontal sidewall vent applications only. This kit may be used on any size furnace in the CHB1/CDB1 family.

Install these optional kits according to the instructions provided with each kit. The location and clearance requirements are identical to those of the standard vent terminations described in this manual.
