What’s wrong with it?
These boilers were manufactured for use with natural gas, but could have a blue tag incorrectly indicating to installers that they are intended for use with LP (propane) gas. If an installer connects one of the boilers to LP gas without installing a propane conversion kit, carbon monoxide (CO) can build up due to incomplete combustion, posing a risk of CO poisoning.

What should you do?
Consumers who had a Weil-McLain Ultra series boiler installed for use with propane and have not already been contacted by their installer should contact the installer or a heating professional for a free safety inspection. If the boiler was not installed with a propane conversion kit, one will be installed at the time of the inspection at no charge. Heating professionals may contact Weil McLain Technical Service at (219) 879-6561 for more information.
