CPSC recommends that every home should have at least one CO alarm that meets the requirements of the most recent Underwriters Laboratories (UL) 2034 standard or International Approval Services 6-96 standard.
Recall Program to Replace Vent Pipes
Consumers should also have the vent pipes on their heating systems inspected. In 1998, virtually the entire furnace and boiler industry together with the manufacturers of high-temperature plastic vent (HTPV) pipes joined with CPSC to announce a vent pipe recall program. The program's purpose is to replace, free of charge, an estimated 250,000 HTPV pipe systems attached to gas or propane furnaces or boilers in consumers' homes. The HTPV pipes could crack or separate at the joints and leak CO.
Consumers can check the vent pipes attached to their natural gas or propane furnaces or boilers to determine if they are part of this recall. They can be identified as follows: the vent pipes are plastic; the vent pipes are colored gray or black; and the vent pipes have the names "**Plexvent®**," "**Plexvent®II**" or "**Ultravent®**" stamped on the vent pipe or printed on stickers placed on pieces used to connect the vent pipes together. Consumers should also check the location of these vent pipes. For furnaces, only HTPV systems that have vent pipes that go through the sidewalls of structures (horizontal systems) are subject to this program. For boilers, all HTPV systems are subject to this program. Other plastic vent pipes, such as white PVC or CPVC, are not involved in this program.
After checking the vent pipes, consumers should call the recall hotline toll-free at (800) 758-3688 Monday through Friday from 7 am to 6 pm CST, to verify that their appliance venting systems are subject to this program. Consumers with eligible systems will receive new, professionally installed venting systems free of charge. Additionally, consumers who already have replaced their HTPV pipe systems may be eligible for reimbursement for some or all of the replacement costs.
