Dec. 2, 2009: AHRI Warns Consumers About Modification of Gas-Fired Appliances
ARLINGTON, Va. - The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) is warning consumers about the dangers of unauthorized and unapproved altering of any gas-fired heating appliance.
AHRI noted that manufacturers must use specific engineering and design knowledge to develop gas-fired heating appliances that operate safely and properly under a variety of conditions. Product designs are tested and certified by third-party independent testing agencies, like CSA International, ETL/Intertek and Underwriters Laboratories for compliance with nationally recognized voluntary consensus safety standards. The association said any unauthorized modification to a gas-fired appliance, no matter how minor, can alter the design and compromise the safety of that unit. For example, an alteration that changes the combustion process may cause carbon monoxide (CO) emissions that exceed the limits specified in the safety standards. Modifications should only be made that are authorized by the original equipment manufacturer (OEM) or other recognized authority and performed by qualified service personnel.
In addition, AHRI said that consumers should beware of companies that offer to make, or instruct consumers about how to make, modifications to various appliances without expressed, written authorization of the OEM. The consumer should always check with the OEM or its local representative to ensure that a modification is authorized.
“Any unauthorized modification to a gas burning appliance voids its safety certification and may expose consumers to a risk of property damage, personal injury, or even death,” said AHRI Chief Technical Advisor Frank A. Stanonik. “AHRI is committed to providing consumers with information on the proper installation and safe and efficient use of gas-fired appliances.”
