tuBe inlet installation figure 19 code restrictions Use of the top inlet water connection is not permitted on installations in the state of North Carolina, due to the material of the tube (Polypropylene). Where such code restrictions exist, use only lower inlet tank connection. This may also require a heat trap -check local codes. The “Top Outlet” connection may still be used on these applications. Plug or cap all unused openings in the tank before filling with water. temperature setting should not exceed safe use temperature at fixtures. see water temperature control and mixing ValVe warning on page 12. if higher preheat temperatures are necessary to oBtain adeQuate Booster output, add an anti-scald ValVe for hot water supplied to fixtures. 20 heater wiring All electrical work must be installed in accordance with the latest version of the National electrical Code ANSI/NFPA No. 70 and must conform to all local code authority having jurisdiction. AN eLeCTrICAL GrOUND IS reQUIreD TO reDUCe rISk OF eLeCTrICAL ShOCk Or POSSIBLe eLeCTrOCUTION. If any of the original wire as supplied with the appliance must be replaced, use only type 105°C thermoplastic or equivalent and 2500C type F must be used for the flame sensor and igniter leads. The controls of this water heater are polarity sensitive. Be certain to properly wire the hot and neutral connections. figure 20 21 gas piping Contact your local gas service company to ensure that adequate gas service is available and to review applicable installation codes for your area. Size the main gas line in accordance with Table 9. The figures shown are for straight lengths of pipe at 0.5 in. W.C. pressure drop, which is considered normal for low pressure systems. Note: Fittings such as elbows, tees and line regulators will add to the pipe pressure drop. Also refer to the latest version of the National Fuel Gas Code. Schedule 40 Metallic Pipe is the preferred material for the gas line of this water heater. It is imperative to follow the sizing recommendations in the latest version of the National Fuel Gas Code if Corrugated Stainless Steel Tubing (CSST) is used as the gas line for this water heater.
