We look for the type of chimney you have, the liner type, if present, the size of your chimney flues, the type fuel you burn, both fireplace, or stove, and central heating. We also check to see if you have a chimney cap installed. A flue is the passageway inside your chimney that conveys the gases out of the home and into the atmosphere. A chimney houses flues. You should have one flue for each fireplace, stove, and furnace or boiler.
Some homes also have a separate flue for their water heater.
All chimneys should have caps to prevent leaves, sticks, debris, animals and most importantly, rain and snow from entering the chimney flue. A chimney cap is designed by codes for your protection. It must be installed and sized properly to vent correctly. In some cases caps actually help eliminate certain downdrafts and improve venting. A damper that has come loose or off its bracket it can be reseated.
