Custom Storage Tanks

After installation, fill the system and run at operating

temperature for at least one day in a closed loop mode.

Then drain system, and refill.

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.

Glass Lined Vessels:

Anodes should be checked and cleaned every six

months. Should their diameter be reduced by 20% or

more, they should be replaced.

LAARS Heating Systems supplies 25 grams of anode

per square foot of tank area.

Replacement anode rods are available from LAARS

Heating Systems. Please specify tank size when ordering.

Incorrect installation can cause failure of storage tanks due to electrolysis. The storage tank must be installed using

dielectric connections and isolation of the tank supports and other tank components from conductive materials.

Regular anode inspection and replacement is required. Damage due to incorrect installation or lack of anode

maintenance is not covered under the limited warranty. For assistance, please call 805-579-5200.

Manway Installation:

NOTE: Not all tanks are equipped with a manway.

LAARS manufacturers under the ASME code HLW

section of the ASME code, in which a manway is not

required. If your vessel has a manway, please follow

these procedures:

Manway covers and gaskets are shipped in place so

they will not be lost in shipment. The bolts are NOT

tightened, so be sure to check for shifting of the gasket

due to vibration in transit.

The bolts are not tightened completely so that the

tank can be opened and cleaned and inspected prior to

service. Once the manway bolts are fully torqued, the

gasket cannot be reused.

For final assembly of the manway, the gasket must

cover the surface of the ring 100% and project slightly

on each side of the ring. The bolts should be tightened

before the tank has been pressurized and then re-

tightened when the tank is at operating pressure.

DO NOT use adhesives, glues, epoxies, or other

such materials to secure the gasket in place. Use only

the gasket that was supplied with the manway. If

additional gaskets are required, or a replacement is

needed, please contact LAARS Heating Systems.
