AERCO Buffer Tank Installation and Maintenance
Technical Instruction Document
TID-0006_0B
3. BUFFER TANK INSTALLATION
Consult your local building codes for water heater regulations and make sure that you acquire
any necessary permits.
NOTE FOR MASSACHUSETTS INSTALLATIONS: Storage tank installations within the
Commonwealth of Massachusetts must conform to 248 CMR 10.00.
Refer to the user manual for the water heater being used to ascertain any special requirements
for your installation and proceed as follows:
Installing the Buffer Tank
1. Clear the area around installation site of all flammable and combustible materials.
2. Switch off the boiler/water heater and allow the system to cool for four hours.
3. Isolate the electrical supply to the existing boiler/water heater by switching off the
electricity at the mains supply point.
4. Turn off the cold water supply to the existing heating system and any other heating
appliance.
5. Turn off the main gas supply valve downstream from the boiler/water heater.
6. If you are replacing an existing buffer tank, be sure to drain and disassemble it according
to the manufacturer’s instructions.
7. Install drain fittings at bottom connection before setting the tank permanently.
8. Place the new tank into position and line it up to be flush with existing plumbing
connections. Connect the buffer tank to the plumbing using appropriate techniques.
9. Ensure ground wires to the boiler/water heater are connected.
10. Turn on mains electric power and mains gas upstream from the boiler/water heater.
11. 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 bleeder valve on the top of the
tank to vent air from the tank so it fills completely.
12. 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.
