Installing the Storage Tank –
Continued
11. Turn on mains electric power and mains gas upstream from the water heater.
12. Turn on the cold water supply to the tank, followed by the main water supply to the
system. Allow the tank to fill with cold water. Open the relief valve on the top of the tank to
vent air from the tank so it fills completely. Close the relief valve when tank is filled.
13. Set the thermostat at your required temperature, switch on the power supply and allow the
water to heat.
14. After installation, fill the system and run at operating temperature for at least one day in a
closed loop mode, then drain system, and re-fill.
NOTE
The tank should be installed in such a manner that should the tank
or any connections leak, the resulting flow of water will not cause
damage.
5. STORAGE TANK MAINTENANCE
Anodes should be checked and cleaned every six months. Should their diameter be reduced by
20% or more, they should be replaced.
AERCO supplies 25 grams of anode per square foot of tank area. Replacement anode rods are
available from your local AERCO sales representative:
•
28”

6. STORAGE TANK FIELD PIPING
NOTE FOR MASSACHUSETTS INSTALLATIONS:
Storage tank installations within the
Commonwealth of Massachusetts must conform to 248 CMR 10.00.
Select the appropriate piping diagrams for your application from the following drawings: Figures
3, 4, and 5 are piping schematics for the stratified storage tank with AERCO water heaters.
Figures 6 and 7 are piping schematics for the accumulator tank with AERCO water heaters.
NOTE
The Innovation water heater can only be piped with a stratified
storage tank to ensure that the maximum continuous flow rate
through the heater does not exceed 50 gpm.
IMPORTANT!
The piping schematics shown in these installation procedures
illustrate only the piping between the water heater and the
AERCO tank. SEE THE APPROPRIATE WATER HEATER
OPERATIONS AND MAINTENANCE MANUAL FOR COMPLETE
WATER HEATER INSTALLATION INSTRUCTIONS.
