Chimney and draft, Chimney Maintenance

Chimney and draft

The chimney is the most important element of a successful stove operation. The chimney ‘drives’ the system by producing the draft that draws in combustion air and exhausts smoke and gases to outdoors.

When installing a new stove or upgrading an existing one, give as much attention to the chimney as you do to the appliance that it serves.

A glowing red hot stove or chimney connector indicates excessive draft. The stoves failure to get hot, or long burn times may indicate poor draft conditions.

Good draft in a cold chimney should be between 0.01” and 0.1” of water column. Your dealer may be able to check this for you.

Recommended Chimney Clearances

The chimney must:

1.extend at least 14 ft. above the collar of the stove.

2.extend at least 3 ft. above the point where it passes through the roof.

3.be at least 2 ft. above anything within 10 ft. radius of the top of the pipe.

Chimney Maintenance

Chimneys serving woodburning appliances must be checked for creosote build-up. Until you are familiar with the rate of creosote build-up in the system, check it often - every couple of weeks.

Creosote may be in the form of dry, flaky deposits clinging to the liner of a shiny, glazed coating that resembles black paint. Glazed creosote is the most dangerous kind and indicates that one or a combination of the following conditions exist.

1.cold liner

2.smouldering fires

3.wet wood

Glazed creosote should never exceed 1/8” (3mm thickness). Dry flaky creosote should never exceed 1/4” (6mm thickness) before it is removed.

Floor Protection

When installing your woodstove on a combustible floor, a non-combustible floor protector is required under the stove to protect the floor from hot embers that may fall when reloading. The floor pad must be a continuous, non- combustible pad (floor tile with grouting or a sheet metal pad). A floor pad should not be placed on top of a carpet. Pad must extend 21” (534mm) in front of the stove in Canada and 18” (458mm) in front of stove in U.S.

Pad must extend 8” (203mm) to the sides and back of the stove.

Pad must extend fully to the wall if using side and back clearances less than these dimensions.

Pad extension must be fabricated from non-combustible materials: 1/2” (13mm) thick minimum with thermal conductivity factor “K” of 0.43 or lower (units of K = btu/h/F/in).

To determine thickness of equivalent material required use formula (“K” x 0.5) / 0.43 = thickness required (“K” value can be obtained from manufacturer of floor material).

Effect of Extractor Fan

It is not permissible to use an air extraction device in the same room as the appliance, unless additional ventilation is provided to compensate the equivalent capacity. Anything that may cause a negative pressure can cause gases or fumes to be pulled into the living area.
