CPSC, Weil-McLain Announce Recall of Ultra 155 & 230 Gas Boilers

The hazard

Weil-McLain has determined that the gas valve mounting screws on the recalled boilers may have not been fully tightened during the assembly process and may have come loose in transportation. Weil-McLain is concerned that loose gas fittings could result in leaking gas, fire and/or explosions, that could cause bodily injuries or property damage.

Incidents reported: None reported.

What to do now

Weil-McLain is providing distributors and installers with a "Safety Notice" package for each boiler containing instructions, replacement screws and a reimbursement form. Installers are also asked to tighten the gas valve union. Installers will be reimbursed $50 for each boiler they inspect.

Contact: Call Weil-McLain at 219-879-6561 between 8 a.m. to 4 p.m. CT, Monday through Friday, excluding holidays, and ask for Consumer Relations, or visit the firm's website at www.weil-mclain.com
