Installing the water heater. WARNING: If local codes require external application of insulation blanket kits the manufacturer's instructions included with the kit must be carefully followed. Insulation Blankets Insulation blankets, available to the general public, for external use on gas water heaters are not necessary. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. This water heater meets or exceeds the National Appliance Energy Conservation Act standards with respect to insulation and standby loss requirements making an insulation blanket unnecessary. The manufacturer's warranty does not cover any damage or defect caused by installation, attachment or use of any type of energy saving or other unapproved devices (other than those authorized by the manufacturer) into, onto or in conjunction with the water heater. The use of unauthorized energy saving devices may shorten the life of the water heater and may endanger life and property. The manufacturer disclaims any responsibility for such loss or injury resulting from the use of such unauthorized devices. CAUTION: If local codes require the application of an external insulation blanket to this water heater, pay careful attention to the following so as not to restrict the proper function and operation of the water heater: ● Do not cover the operating or warning labels attached to the water heater or attempt to relocate them on the exterior of insulation blanket. Do not apply insulation to the top of the water heater. This will interfere with the safe operation of the draft hood.  Do not cover the burner access door, jacket door, gas control (thermostat)/gas valve or pressure and temperature relief valve. Heat Traps For increased energy efficiency, some water heaters have been supplied with factory installed 3/4" NPT heat traps in the hot outlet line and cold water inlet line. NOTICE: Do not apply heat to the HOT or COLD water connections. If sweat connections are used, sweat tubing to adapter before fitting adapter to the water connections on heater. Any heat applied to the water supply fittings will permanently damage the dip tube and/or heat traps. During Installation of this water heater...........
