This number is used to identify parts for your boiler, track service history, and aid in the registration and warranty claim processes. Your heating professional should have this number handy prior to any troubleshooting with Weil-McLain Technical Support.
The CP number for your boiler will be printed on a small rectangular barcode sticker on either side of the boiler jacket. For some models such as the ULTRA, the CP number may be inside the boiler jacket near the heat exchanger. If you know your boiler model but do not know where to find your CP on your boiler, use our CP Location Reference Guide to verify location of the CP number by model.
Your local heating professional should perform a heat-loss estimate based upon the size and construction of your home before recommending a boiler size and model.
Weil-McLain does not sell direct to consumers. Our products are sold exclusively through our wholesale distributors to contractors. If you are a heating contractor, contact your local wholesale distributor for pricing and availability. For distributors near you, use our Distributor Locator. If you are a homeowner, facility manager or building owner, contact licensed professional heating contractors for price quotes. Use our Contractor Locator.
Problems & Troubleshooting
Please contact your local heating professional to troubleshoot your system. Your heating professional can contact a Weil-McLain distributor or our technical service department for additional assistance.
Weil-McLain® does not employ heating technicians who come out to repair your boiler, nor do we have factory-authorized servicers. We rely upon independent heating professionals in your area to install, maintain and troubleshoot Weil-McLain products. Please contact a heating professional in your area. If needed, your heating contractor can contact our area office or our technical service department for assistance with trouble-shooting problems.
If you are a homeowner who installed your own boiler and are not a professional heating contractor, you must contact the distributor/dealer who sold you the boiler for technical support and warranty action.

System Operation
Certain types of anti-freeze can be used with Weil-McLain® boilers. We recommend your hired heating professional use an anti-freeze designed for hydronic systems and formulated with inhibited propylene glycol, a non-toxic antifreeze. Do not use automotive antifreeze.
The average setting for a forced hot water system is 180°F (lower for in-floor heating). It can be raised as high as 210°F if needed in severe weather. For systems that use coils to heat domestic hot water, the high limit setting is 210°F and the low limit setting 140°F. A differential setting of 15°F is recommended for the optimum amount of domestic hot water.
