CSA International and Laars Heating Systems Company announce a voluntary recall of gas boilers and water heaters

In cooperation with CSA International, Laars Heating Systems Company of Rochester, New Hampshire announces the voluntary recall in Canada of approximately 82 units of the 9600 CB Series Condensing Boilers and 9600 HWG Series Condensing Water Heaters. Internal black plastic venting components in the boilers and water heaters can crack and leak flue gases, including carbon monoxide (CO), posing a risk of CO poisoning.

No injuries or incidents have been reported.

This recall involves the Laars 9600 CB Condensing Boilers and Laars 9600 HWG Condensing Water Heaters. The CB series is installed as a space-heating appliance to generate hot water used in a closed-system loop for hydronic heating systems, such as baseboards or radiant flooring. The HWG series is installed as a water heater to generate hot water for domestic use, such as showers, sinks and dishwashers. Consumers can identify the units by the label on the front that includes the headline “Mark II” at the top and then either “9600 CB” or “9600 HWG” directly under the headline. The jacket colours are either putty and black, or taupe (dark grey) and black. On the right side, a data plate repeats the information, and also contains the specific model number and BTU size as indicated below. Only the following product names and model numbers are included in this recall:
