New Low-Level Carbon Monoxide Monitor Can Help Save Lives…and Your Business

HVACR contractors and technicians are responsible for the byproducts of any combustion appliances that they install, service, and maintain. Even when properly installed and maintained, combustion appliances can still generate carbon monoxide. Carbon monoxide (CO) poisoning has led to HVACR contractors being sued and/or charged with the death of their clients. Situations like this are avoidable by including a low-level carbon monoxide monitor with each installation, service, or maintenance call they perform. While there… Read More

Carbon Monoxide: Three Airflow Impacts on Combustion Safety

By David Richardson Fuel-fired appliances need controlled and consistent combustion air for safe operation. If this fact is ignored, the results can be deadly. Equipment installations that get combustion air from indoors require special care to assure safe operation. Let’s look at three ways airflow impacts the safe operation of fuel-fired equipment. Natural Airflow Natural airflow conditions constantly affect building air movement. To assure safety, combustion air must be controlled. The three biggest combustion air… Read More

Bacharach Releases Monoxor XR High Range CO Exhaust Gas Analyzer

Bacharach, an industry expert in gas detection and analysis instrumentation, introduces the Monoxor XR (extended range) hand-held exhaust gas analyzer for measuring CO (carbon monoxide) in ambient air or directly from the exhaust pipe of forklifts, floor burnishers or other equipment burning propane, gasoline, diesel, or CNG (compressed natural gas). Bacharach Monoxor XR The Monoxor XR is the ideal instrument for verifying worker safety and achieving compliance with OSHA air quality regulations. It can also… Read More

Carbon Monoxide: Be Thankful for the Mentors in Your Life

By David Richardson In September 2019, I found out that Jim Haney – director of the Bluegrass and Great Lakes HVAC Insider newspapers planned to retire. This caused me to reflect on the 12 years that I’ve been writing for him and the opportunity he first gave me. This month I’m going to stray from my normal CO (carbon monoxide) and combustion topics to share the influence that Jim had on an HVAC guy… Read More

Carbon Monoxide: The First Line of Defense Against Carbon Monoxide

By David Richardson The news media frequently promotes store-bought carbon monoxide (CO) alarms as the first line of defense against CO poisoning. It’s an easy position to take since there is no accountability. Plug the alarm into a receptacle and you’re protected, right? What if the CO alarm sounds? Many suggest that you call the fire department or gas company. Once they arrive, the house is usually aired out. The mysterious CO leak isn’t… Read More

Carbon Monoxide: When to Test the Intake of Condensing Equipment

By David Richardson Those who conduct combustion tests regularly understand how frustrating it can be to identify the source of unstable CO (carbon monoxide) and O2 (oxygen) readings. If you’re testing a direct-vent (two-pipe) 90% condensing furnace, a simple test can help you eliminate one potential cause of unstable combustion – flue gas recirculation. Often you may see visual clues of recirculation such as, rusting in the burner compartment and condensation, but don’t know… Read More
