Combustion Safety
If you have and gas appliances, one of the first thing that we will want to do when we arrive at your home is to test for excessive carbon monoxide levels. We use a combustion analyzer to check the CO levels throughout the house. If the CO level goes over 35 ppm this tells us that there problem we will attempt to turn off the appliance and determine to source of the excessive CO. We may be able to turn off the appliance and continue with the audit. If the excessive CO level cannot be stopped we will evacuate the house and help you get the necessary help to correct the problem.
We also use a gas leak detector to check for a gas leak in the gas supply lines throughout the house.
We experiment with the pressure differences under all conditions in the house to verify that the exhaust from the gas appliance will be exhausted from the house under the worst pressure conditions. This means turning on all of the bathroom fans, stove vents and the clothes dryer to create a negative pressure in the house and verify that the gas vent will draft under the worst conditions.
Unvented fireplaces will generate CO and should be avoided, or replaced.
If you have any gas appliances or unvented fireplace in your house then you need to have CO alarms and monitors near the areas with these appliances.
