Many safety-related messages and instructions have been provided in this manual and on your own water heater to warn you and others of a potential injury hazard. Read and obey all safety messages and instructions throughout this manual. [. . . ] · For Schedule 40, 3" PVC, ABS, Coex Cellular Core vent pipe: Every 3. 5 feet (1. 1 m). · For Schedule 40, 4" PVC, ABS, Coex Cellular Core vent pipe: Every 4 feet (1. 2 m). · For Schedule 40, 2" CPVC vent pipe: Every 5 feet (1. 5 m). · For Schedule 40, 3" CPVC vent pipe: Every 6 feet (1. 8 m). · For Schedule 40, 4" CPVC vent pipe: Every 6. 5 feet (2. 0 m). It is imperative that the first hanger (or support) be located on the horizontal run immediately adjacent to the first 90-degree elbow from the vertical rise. Support method used should isolate the vent pipe from the floor joists or other structural members to prevent the transmission of noise and vibration. Do not support, pin, or otherwise secure the venting system in a way that restricts the normal thermal expansion and contraction of the chosen venting material. If the water heater is being installed as a replacement for an existing power vented heater in pre-existing venting, a thorough inspection of the existing venting system must be performed prior to any installation work. Verify that the correct material as detailed above has been used, and that the minimum or maximum vent lengths and terminal location as detailed in this manual have been met. Carefully inspect the entire venting system for any signs of cracks or fractures, particularly at the joints between elbows and other fittings and the straight runs of vent pipe. Check the system for signs of sagging or other stresses in the joints as a result of misalignment of any components in the system. If any of these conditions are found, they must be corrected in accordance with the venting instructions in this manual before completing the installation and putting the water heater into service. Except where instructed in this manual, the mixing of 2", 3" and 4" vent pipe is NOT ALLOWED. If 2" pipe is to be used, then a 2" to 3" bell reducer is recommended. If the bell reducer is located at the rubber boot on the blower assembly, then a short section of 3" vent pipe needs to be installed in the rubber boot for proper connection of the 2" to 3" bell reducer. If 4" pipe is to be used, then a 3" to 4" bell reducer is recommended. If the bell reducer is located at the rubber boot on the blower assembly, then a short section of 3" vent pipe needs to be installed in the rubber boot for proper connection of the 3" to 4" bell reducer. The water heaters covered by this manual are supplied with a 2" Schedule 40 PVC 22. 5° Vent Terminal. If you decide to vent with 3" or 4" pipe, a Schedule 40 DWV 45° Vent Terminal must be used. For your convenience, we have included a screen for both 3" and 4" Vent Terminals. The vent piping should be connected to the blower with a rubber adapter and secured with hose clamps.
