If your boiler is leaking, contact your installer or a professional heating contractor of your choice. Use our contractor locator for a list of contractors in your area. If the unit needs to be replaced immediately, your heating contractor should obtain the appropriate cast iron section block or boiler from a local wholesale distributor.

Warranties are not approved sight unseen, and field representatives cannot make any type of warranty determination while the boiler is still installed.

For warranty consideration, the leaking boiler or section block should be returned to the same wholesale distributor where the replacement was purchased. Our field representative will then do a thorough inspection of the product at the wholesale distributor. At that time, claim credit or denial will be processed based on the findings. Credits for warranties are processed through the wholesale distributor; Weil-McLain does not reimburse consumers directly.

To clean a steam boiler, a heating professional can:

• Use one pound of trisodium phosphate for every 50 gallons of water content. 

• Heat the boiler to 180°F; hold at 180°F for two hours.

• Do not allow the boiler to make steam. 

• After two hours, drain the boiler and fill with fresh makeup water. Water treatment chemicals should be reviewed before they are introduced into the boiler. Foaming agents that will interfere with steam action are of particular concern. Sodium carbonate (up to one pound for every 30 gallons) or sodium hydroxide (lye) (up to one pound for every 50 gallons) may be used.

• Check pH level after cleaning. It should be between 7 and 8.5. A small amount of cleaner may be added to adjust the pH up to the proper range.

• DO NOT use petroleum-based products in the boiler.

To clean a cast iron boiler, a heating professional can:

• Use one pound of trisodium phosphate for every 50 gallons of water content. 

• Fill, vent and circulate the system with above mixture, allowing it to reach design or operating temperature if possible. 

• After circulating a few hours, drain the system completely and refill with fresh water. Usually, enough of the cleaner will adhere to the piping to give an alkaline solution satisfactory for operation: a pH reading between 7 and 8.5. Sodium carbonate (up to one pound for every 30 gallons of water content) or sodium hydroxide (lye) (up to one pound for every 50 gallons) may be used.
