What is acceptable reading for flue gas Analyser?

Flue gas analysers usually display a CO/CO2 ratio. This shows the ratio of carbon monoxide and carbon dioxide in the exit flue (chimney) of the appliance. Generally when this level is below 0.004 the boiler is considered to be running efficiently.

What does a combustion analysis tell you?

Combustion analysis is a method used in both organic chemistry and analytical chemistry to determine the elemental composition (more precisely empirical formula) of a pure organic compound by combusting the sample under conditions where the resulting combustion products can be quantitatively analyzed.

What is the acceptable CO level in the flue?

Professionally trained technicians get a minimum of three readings during equipment operation. Ideally, CO measurements should be less than 100 ppm and stable during the run cycle for vented gas-fired HVAC equipment. The ANSI Z-21 maximum CO level is 400 ppm air-free.

What is high CO on combustion analysis?

High Carbon monoxide readings tend to point to what I like to call unbalanced combustion. You see, it could be due to lack of combustion air, too much gas, or too much excess air. No matter how you slice it, the combustion process is out of balance.

What is the combustion analysis?

Combustion analysis is a standard method of determining a chemical formula of a substance that contains hydrogen and carbon. First, a sample is weighed and then burned in a furnace in the presence of excess oxygen. All of the carbon is converted to carbon dioxide, and the hydrogen is converted to water in this way.

What are the acceptable levels for combustion analysis?

CO(AF) 400ppm - Shutdown Unit

What is the purpose of the combustion test?

The combustion safety test will make sure that heating and cooling equipment is running safely and efficiently. A safety test can identify things like high carbon monoxide levels in the home, which can lead to sickness and even death.

What is a good CO2 reading for combustion?

Every manufacturers have their own specs that they want. Installation manual will have the info. Usually between 10 and 11 CO2, around 5 for 02 and under a hundred ppm for co.
