Follow these tips to keep your fireplace/woodstove and chimney working safely
and efficiently each year!
The Ontario Fire Code requires homeowners to maintain their
heating appliances in safety operating condition. The Technical Standards
and Safety Act 2000 requires homeowners to have heating appliances
inspected, including chimneys or vents.
Check stovepipes and connections. Ensure that screws are
located at every joint and that each connection is a tight fit. Also look
for signs of dark staining or white powder (leeching) at every joint. Rust
is a clear sign that it is time to replace the pipe.
Check for creosote. Creosote is a by-product of combustion
that can form quickly on the interior walls of your chimney. It is black or
brown gummy substance that builds up on the flue. A buildup of creosote can
catch fire, so have your chimney cleaned professionally as required.
Check walls for heat. If the wall above or behind your
fireplace or stove gets very hot, it could be a sign of improper
installation. Have it checked by a WETT certified professional.
Protect walls and floors from heat and sparks. Keep
combustible objects away from your wood stove or fireplace. Fireplace
openings should always be protected by a properly fitted screen and wall and
floor surfaces around the fireplace/stove should be covered or constructed
of noncombustible materials.
Inspect the masonry chimney, looking for leeching on the
outside bricks as well.
Check for missing pieces in the chimney liner as well (these
pieces may be found in the clean out door at the bottom of the chimney) and
if found, have the chimney liner checked by a professional.
Ensure doors, gaskets, seals, baffles and flues work as
required. If not, have them repaired right away.
Always ensure that exterior vents are kept clear of snow or
other materials that may block them.
Remember: When using any fuel fired appliance, always
make sure you have a carbon monoxide detector installed in the sleeping areas!
