Plumbing
Domestic Water Piping
1.Connect the cold water supply to the connection labeled
COLD WATER.
2.Connect the HOT WATER piping to the domestic hot water system.
3.When all domestic water piping is complete, open the cold water supply and allow some water to enter the tank. Look and listen for signs of leaks and repair as necessary before continuing.
Note: If installing on a city supply, a properly sized thermal expansion tank is required and should be installed in accordance with the product installation manual.
Note: If an external electrical source is utilized, the appliance, when installed,must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70.
Note: The temperature control is adjusted to 120°F, when shipped from the factory.
4.Install the T & P relief valve and plumb a blow down tube. Plumb to within 6 inches above a floor drain or as directed by plumbing code.
Do not drill, puncture or otherwise penetrate 
the outer tank shell. Do not screw pipe hangers or other hardware into the exterior of the tank.
Clearance From Combustible Surfaces
Boiler Piping
1.Plumb the circulator or zone valve on the BOILER SUPPLY line.
2.Pipe the BOILER RETURN connection to the boiler return line.
Be sure the return line is NOT plumbed to 
the suction side of any heating circulators. This may require moving the heating circulator off the boiler tapping on packaged boilers. Failure to do so will result in overheating and tank damage when the heating system is in operation.
3.Install a weighted flow check on the boiler return line or use a circulator pump with integral check valve. This is not necessary on systems utilizing a zone valve to control the water heater temperature.
4.After completing the boiler piping, slowly open the boiler fill valve and pressurize the water heater loop. Check for leaks and repair as necessary. Proceed to the appropriate wiring section in this manual.
EXPLOSION HAZARD. Do not install to a high pressure steam boiler (greater than
15 psig). An explosion could occur.
