Domestic Water Connections

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.

The water connections must be installed in accordance with all national and local plumbing codes, or any pre- vailing standard. NEVER USE DIELECTRIC UNIONS

OR GALVANIZED STEEL FITTINGS ON ADVANTAGE PLUS CONNECTIONS. The inlet and outlet connections are 1" on the 45 gallon models and 1-1/2" on the 80 and 119 gallon models. On the cold inlet, install a 1" brass tee on the 45 gallon models, or a 1-1/2" brass tee on the 80 and 119 gallon models. On the run of the 1" brass tee install, with pipe sealant, compound a 1" brass drain cock or it's equivalent (not supplied). Into the branch of the 1" or 1-1/2" brass tee install a copper male adapter to match with the copper plumbing system. For convenience, you may install a shut off valve and a union in the cold inlet piping to ease servicing in the future. If there is a back flow preventer, or any type of a no return valve in the sys- tem, then you must install an additional tee for a suitable potable thermal expansion tank. (See section on Expansion Tank.) In the hot outlet connection, (top left), install a suitable adapter to match the copper tubing of the plumbing system. A thermal trap or heat trap loop may be installed here to provide additional energy sav- ings and prevent thermal siphoning of domestic hot water. A domestic hot water tempering/ anti-scald valve should be installed into the hot water line to prevent the

maximum outlet water temperature from exceeding 125° Fahrenheit to prevent scald injury.
