Friends and Colleagues:

Reading the threads on the Digest, it appears that no one has mentioned

NOx, the, nitrogen oxides that are produced when burning a fossil fuel.

(Most emissions are originally NO but they can be converted to NO2 .)

NO2 is a respiratory irritant at low levels.

http://www.epa.gov/iaq/schools/tfs/guidee.html#Nitrogen Oxides (NO, NO2)

and http://www.epa.gov/iaq/no2.html. Children in homes with gas stoves

have more respiratory symptoms.

This only occurs with burning the fuels, and has nothing to do with a

possible sensitivity to natural gas itself, which dominated yesterday's

thread.

Henry: I understand that it is the process of combustion of a compound containing no nitrogen (natural gas) that produces the NOx. According to my reading, in fossil fuel combustion, nitrogen is taken from the atmosphere and combined with oxygen to produce NOx. Thus if a person gets reactions from natural gas, it is impossible that this can be attributed to the gas coming out of the pipe.

Barbara: Gas heaters can be designed so that no combustion products enter the living space. The better quality high efficiency furnaces with air supply blowers fall into this category. My furnace is located in the attic, brings in outside air for combustion of the gas and exhausts the burned gas back to the outside. A furnace with an intact heat exchanger and exhaust pipe will not blow any combustion products into the living space. Some gas wall heaters may not exhaust combustion products to the outside. In this kind of situation, they operate similar to the gas burners on a kitchen stove.

Barb: My point was that natural gas as it arrives at the house has no nitrogen. If sensitivity to unburned gas is noticed, it cannot be because of the NOx. The nitrogen oxide found in exhaust gases occurs because the nitrogen is coming from the air you breathe, since the atmosphere is composed of 78% nitrogen. When combustion occurs in a blue flame, the methane in natural gas combines with oxygen and nitrogen from the atmosphere and produces carbon dioxide and nitrogen oxide. If the flame is yellow, some carbon monoxide is produced. That is why it is important that the gas burns with a blue flame.

Carol: At the risk of accusations of being a know-it-all, some time ago I suggested turning off the gas to each and every gas appliance in your house (all off at the same time) and checking your gas meter every day to see if it moves. You may have a leak within the walls of your residence.To turn on the gas appliances after your test, you probably need to call the gas company. This is what is generally recommended.My hobby is finding out as much about indoor environments as I can dig up. I have been reacting to chemicals and mold for much of my 76 year life. I constantly probe to find out what is making me sick.I hope you eventually find out what is making you sick. If you determine that there is no gas leak anywhere in your house, you have eliminated one more irritant. Another possibility is formaldehyde in your kitchen cabinets. Sealing the sawed ends of each panel in each cabinet will go a long way toward reducing formaldehyde emissions.

Barb,

The most common method to check a gas burning appliance for proper venting is to check the air by the appliance with a direct reading carbon monoxide detector.

Keep in mind that gas water heaters and furnaces are vented to the outdoors. Gas ranges/ovens are only vented to the outdoors if there is an adequately installed and functioning exhaust fan (not just a re-circulating fan) above the appliance.

CO measurements can be made and reported in two ways. “As measured” is the most common and refers to the amount of CO in air (usually reported in ppm or

sometimes %). 0 ppm “as measured” CO concentrations are ideal, but realistically should not remain above an average of 9 ppm for greater than 8 hours or average 35 ppm for 1 hour. “Air free” determines the amount of CO in a sample by compensating for the

amount of excess air. This is computed from CO and O2 (sometimes CO2) measurements. This typically requires the use of a Combustion Analyzer that can withstand the temperature of flue gas and has the ability to remove water vapor. The “air free” method is

used to determine the source strength of CO.

Your HVAC technician may have been using a Combustion Analyzer to determine if the furnace was operating properly based on guidelines such as the following:

< 100 ppm CO air free: Gas furnaces, space and water heaters

are usually considered safe and left in operation (25 to 50 ppm typical).

<150 ppm CO air free: Common ceiling concentration for unvented

gas oven emission.

100 – 400 ppm CO air free: Gas appliances require further testing

and correction

>400 ppm CO air free: Gas systems commonly shut off and/or

corrected.

ANSI Z21 standards specify that furnace flue gas should not exceed 400 ppm CO air free and a gas range/oven should not exceed 800 ppm CO air free. The required

test for the gas range/oven, however, is difficult to perform in the field (your house).

The technician may have gone outside to make a flue gas measurement to avoid needing to put a hole in your flue pipe. If the technician found 17

ppm CO air free in the furnace flue gas, that would indicate the furnace was properly adjusted. If the technician found 17% (equals 170,000 ppm) CO air free that would indicate a serious problem. The best thing to do would be call the HVAC company

back and ask for clarification about what the technician did, what the results were, and what those results indicated.

Another possible association with the use of the oven or stove and an increase in emissions of volatile chemical compounds in the kitchen might be the heating of the walls and cabinets and convective air flow patterns. In other words, the heat from the stove (gas or electric) may increase offgassing from materials in the kitchen.

Carol,

What about Teflon? I remember reading about some problems when frying pans were overheated.

Are you cooking different types of food or using different cooking oils etc.?

What about grease and combustion by products collecting in the exhaust hood. I know that many times, the back draft damper in the duct above the hood can be "glued" in place by grease. If the damper is closed then the combustion by products could not escape to the exterior. Also, grease in the hood could off gas when heated. Check the exhaust hood and duct systems to insure they are clean and working properly.

Carol,

Keep in mind that just because a flame is producing carbon monoxide, or nox, it does not mean it is being released into the living space. If the venting system is working properly all the combustion by products should exhaust to the exterior. In order for the unwanted combustion by product to find a pathway into the breathing air there must be something wrong with the vent system. While it has been suggested that carbon monoxide detectors and other speicalized equipment can be used to find a venting condition, try starting with a mirror. Combustion by products are composed mostly of carbon dioxide and water vapor. When water vapor comes in contact with the cold surface of the mirror it will condense on the mirror. This is an easy and first step to determne if there is a venting problem. Typically a water heater has a draft hood where the water heater connects to the vent at the top of the tank. This is usually where the vent puffs,or back drafts, spilling combustion by products into the surrounding air. Placing a mirror next to the draft hood is an easy way to determine if there is any spilling. Try placing a mirror nearby any flames and see what happens.

The flexible metallic conduit and high temperature insulated leads provided with some appliances are evaluated as a component part of the appliance. Unless a conduit fitting or outlet box is installed at the factory, tape or other means is provided at the end of the conduit to protect the conductors during shipment. This protection is not intended to take the place of a conduit bushing or fitting which is required by the NEC.
