TYPICAL INSTALLATION
• Read label on provided T&P valve before
beginning installation.
• No valve may be placed between the relief valve
and water tank.
• To avoid water damage, discharge line must be run
to a safe place of disposal and must pitch downward.
• Do not install a shut-off valve, plug or cap in the
valve discharge line.
• Follow local codes where they vary from these
instructions.
4) Attach the threaded flexible water heater connection hose
to the domestic hot water outlet of the T&P relief valve.
5) Using the 3/4” push-fit flexible water heater
connection hose, attach the cold water supply line to the
inlet of the MODEL 1 on the bottom of the unit. If

valve (ball valve) on the inlet side of the MODEL 1 Water
Heater to provide a convenient shut-off point.
