## Hazards

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.

## Description

The recall involves Weil-McLain Ultra 80, Ultra 105, Ultra 155, Ultra 230 and Ultra 310 condensing, high-efficient, gas-fired boilers for space heating.
