Refer to Use and Care Manual. If your home has copper water pipes, you can solder the water pipe connections or use SharkBite or push-fit type of fittings that dont require soldering. If you have increased the temperature setting and the Thermostatic Mixing Valves are not set properly (or not installed) you could scald yourself while checking the temperature. At lower temperatures and relative humidity levels, efficiency will be lower and recovery will take longer. Connect these 2 wires to the 2 wires on the water heater using wire nuts or other connectors. WARNING: If local codes require external application of insulation blanket kits the manufacturers instructions included with the kit must be carefully followed. . Water Leak Sensor Not Installed. If your toilet occasionally runs for no apparent reason (usually briefly at night), that may be due to thermal expansion increasing the water pressure temporarily. Remove the jacket access panel(s) and insulation. Remove the aerator at the nearest hot water faucet. Inspect the drain pan, pipes, and surrounding area regularly and fix any leaks found.
