Frequently Asked Questions
Q: My chimney has suddenly started smoking?
A: This could be caused by the flue being blocked by mortar or something else; try getting the chimney swept.
Q: Smoking gets worse over a period of time?
A: Your flue is likely to be partially blocked by soot or tar; try getting the chimney swept.
Q: My fire smokes in certain wind directions and conditions?
A: This could either be pressure variation, or downdraught. For downdraught fit an anti-downdraught cowl such as the Brewer UFO. For pressure variation you need to increase the room pressure.
Q: What is downdraught?
A: Where wind for various reasons blows down the chimney preventing gases and smoke from rising up the chimney to the atmosphere.
Q: What is pressure variation?
A: Where the pressure at the fire is less than at the chimney pot, sucking air down the chimney.
Q: Why does my fire smoke when the doors and windows are closed?
A: This is probably caused by lack of ventilation which is causing the pressure to drop in the room. You need to add ventilation and fitting the Brewer Aspirotor would also help.
Q: I have a large opening fireplace that smokes most of the time.
a) The opening may be too big for the flue - reduce the fire size to correct ratio and smoke level.
b) You may have a blocked chimney; try getting it swept.
c) If you have downdraught fit a Brewer U.F.O Cowl
My standard size fireplace smokes most of the time?
a) Your flue may be too large or too small; try changing to the correct ratio.
b) You may have a badly formed throat/lintel. There must not be a flat surface directly over the fire.
c) If you have downdraught fit a Brewer UFO Cowl or a Mini Anti Down Draught Cowl
Q: What precautions should I take if I no longer use my chimney?
A: It is important to protect these types of chimney, especially in the winter. The rain/freeze cycle can cause structural damage to the chimney or adjacent brickwork. By fitting a Chimney Cap (C-Cap) rain and birds are prevented entry, but important nominal ventilation is maintained.
Q: How often should I sweep my chimney?
A: The National Association of Chimney Sweeps (NACS), strongly recommends that smokeless fuel systems be swept once a year, bitumous coal twice a year, wood quarterly and oil and gas once a year.
Q: I have been told I have a leaky flue, what does this mean?
A: This is where two flue's are built with a common dividing brick wall, which over the years could be breached so gases do not escape correctly.
