For Your Safety AN ODORANT IS ADDED TO THE GAS USED BY THIS WATER HEATER. PRINTED IN THE U. S. A. 185380-000 SAFE INSTALLATION, USE AND SERVICE Your safety and the safety of others is extremely important in the installation, use and servicing of this water heater. 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. [. . . ] 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. Even though the flue gas temperature leaving the blower is between 140°F (69°C) and 175°F (79°C), some installations will have water vapor condense in the vent piping. If this occurs, then adequate means of draining and disposing of the condensate needs to be made by the installer. 18 CONDENSATION Condensate formation does not occur in all installations of power vented water heaters, but should be protected against on installations where it can form in the venting system. Condensation in the venting system of power vented water heaters is dependent upon installation conditions including, but not limited to ambient temperature and humidity of installation location, ambient temperature and humidity of venting space, vent discharge and slope, and product usage. In certain conditions, installations in unconditioned space or having long horizontal or vertical vent runs may accumulate condensate. In these conditions, the vent pipe should be sloped downward away from the blower assembly 1/4" (6. 4 mm) per five feet (1. 5 m) of pipe but not more than 1 1/2" (3. 8 cm) in the total vent length. If the vent piping is vented level or sloped upwards away from the blower assembly, then adequate means for draining and disposing of the condensate needs to be made by the installer (if condensate is detected). If you have condensate, then a 3/8" drain hose can be connected to the built-in drain port of the rubber boot on the blower assembly. For your convenience, the rubber boot is supplied with a removable cap on the built-in drain port. Prior to operating the water heater, make sure the removable cap is installed on the drain port (if a drain hose is not needed). MAXIMUM VENT LENGTHS 40, 000 BTU Units: For 2" Venting, the maximum equivalent feet of pipe allowed is 40 feet (12. 2 m). This does not include the supplied vent termination for the water heater. For the 2" venting, one 90° elbow is approximately equal to 5 feet (1. 5 m). It is recommended that at least 2 feet (0. 6 m) of spacing be used in between all 45° elbows and all 90°elbows.
