Flue Pipes

Flue Pipes for Wood Stove Installation and Inspection in Barrie, Alliston or OrilliaFlue pipes carry the exhaust gases from the appliance flue collar to the base of the chimney. They have been referred to as the “weak link” in the wood-burning system because they are too often installed improperly. As you will see from the list below, there is a number of rules for the safe installation of flue pipe assemblies. These rules apply to flue pipes connected to all wood-burning appliances, including central heating systems.

Flue pipe assemblies should be as short and direct as possible between the appliance and the entrance to the chimney in order to maintain chimney draft. The ideal assembly is one that rises straight up from the appliance flue collar and directly into the chimney with no elbows. A straight flue pipe assembly offers the least restriction to gas flow and results in stronger draft. Straight assemblies also need less maintenance because there are no corners for creosote deposits to accumulate.
Flue pipes may be metallic or wooden. Metal pipes are usually circular in cross section; wooden pipes, square or rectangular, though triangular and round wooden pipes do exist. Read More

WETT Inspection Barrie, Alliston and Orillia

WETT Inspection Barrie, Alliston and Orillia

A fireplace insert is best described as a woodstove inserted into the fireplace opening. The most common reason for an insert being installed is to increase the efficiency of your fireplace. The Ontario B365 Code which is the regulating authority governing solid fuel burning appliances, states in section 5.5.1:

Masonry chimneys. When chimney fires occur in masonry chimneys, the 2100 degree temperatures, and the extreme pressure’s that result, often crack the terra cotta clay flue tiles which line the WETT inspections Barrie, Orillia and Allistonchimney. Chimney fires are NO ordinary fires! They frequently melt dampers and chimney caps, and can actually “melt” mortar! Flue tiles expand until they crack when subjected to such extreme temperatures. These cracks then provide a pathway for flame under intense pressure to reach the combustible wood frame of the house. Enough heat can also be conducted through a perfectly sound chimney to ignite nearby combustibles. Even if a first chimney fire doesn’t seem to have harmed a home, the structure may be so weakened that a second fire will burn it down.

In the past, most installers placed inserts in the fireplace without any chimney connections. This method, in some cases, allowed creosote to build up inside the fireplace, presenting a potential fire hazard. To prevent this, the National Fire Protection Association (NFPA) now requires that inserts be installed with at least (minimum) a positive connection to the chimney.

Space Heating

Space Heating and WETT Inspections

Space heating involves a self-contained device for heating an enclosed area. Space heating is generally employed to warm a small space, and is usually held in contrast Wett Inspections - Newer Wood Stovewith central heating, which warms many connected spaces at once. The inspection includes ensuring manufactures installation instructions are followed and wood burning units are installed in accordance with their listing requirements. The verification of installation is done by a Certified Inspector. Space heaters which do not have a ULC or other agency’s Certification Data Tag will have to have 48 inches of clearance from combustibles. This is an important part of the Inspection and home owners can easily verify for themselves whether of not their space heater is Certified prior to paying for an inspection.

Newer style space heaters are more efficient than previous models with some have catalytic inserts that burns with a higher efficiency.  The catalyst needs to be replaced every 5 years or so.  Even though catalytic stoves are recommended for home owners who are replacing a major part of their homes heating there are non-catalytic stoves which have a secondary combustion chamber which helps reduce emissions.  New stoves can produce 90 % less particulate and smoke emissions.
