Solid-Fuel-Fired Central Heating Appliances
This is the second edition of CSA Standard B366.1 (now CAN/CSA 8366.1), Solid-Fuel-Fired Central Heating Appliances.
In 1979 CSA published Preliminary Standard 8366, Solid-Fuel-Fired Appliances for Residential Use, which covered both central-fired units and space heaters. Subsequently, it was decided to replace 8366 with two new Standards, as follows:
(a) B366.1, Solid-Fuel-Fired Appliances for Residential Use (now titled Solid-Fuel-Fired Central Heating Appliances), and
(b) B366. 2 Space Heaters for Use with Solid Fuels.
Together these Standards supersede B366.
Supplement No. 1-1985 to 8366.1 added requirements for automatically fuelled solid—fuel-burning appliances (both mechanically and gravity fed); for solid-fuel-fired appliances added onto forced-warm—air electric furnaces (Clause 13) to provide an alternative source of heating; for wood chip and wood pellet fuel for use in automatically fuelled appliances (Table 1B); and for catalytic combustors.
Supplement No. 2-1986 added requirements for solid-fuel—fired warm-air furnaces intended for connection to ductwork serving an existing natural-gas- or propane-fired warm-air furnace (Clause 14) to provide an alternative source of heating.
In addition, the following major changes have been incorporated in this edition of B366.1:
(a) The requirements and tests regarding the supply of combustion air, and the fuel-loading level, have been revised significantly.
(b) Figures 2 to 6 have been clarified and a new Figure 7 has been added.
In recent years, much emphasis has been placed on energy conservation and there has been a great deal of renewed interest in the use of solid fuels, such as wood and coal, as energy sources for residential heating. This has resulted in a proliferation of solid-fuel-fired heating appliances on the market and a demand that they be subject to controls in the interest of public safety. CSA has responded to this demand by developing both this Standard on solid—fuel-fired central heating appliances and CSA Standard B366.2 on space heaters for use with solid fuels. It is intended that these appliances be installed in accordance with CSA Standard CAN/CSA-B365, Installation Code for Solid-Fuel-Burning Appliances and Equipment.
It has been approved as a National Standard of Canada by the Standards Council of Canada.
This Standard applies to manually or automatically fuelled solid—fuel-fired central heating appliances that have provision for venting directly to the outdoors by means of flue pipes, chimneys, etc.
This Standard applies to appliances, factory- or field—assembled, that have been, or could have been, completely assembled at the manufacturer’s plant and transported in the assembled condition.
This Standard also applies to the manually or automatically fuelled solid-fuel features of a combination solid—fuel-fuel-oil-fired appliance, where the solid-fuel features may affect the safety or performance of the oil-fired appliance. In these cases, requirements in this Standard are additional to the requirements for the specific oil-fired appliance.
This Standard also applies to outdoor-aired solid— fuel—fired appliances. For the purposes of these requirements, “outdoor-aired refers to appliances wherein all combustion air is to be taken directly from the outdoors.
This Standard also applies to solid-fuel-fired furnaces intended to be added on directly in series at a point after the warm air leaves the forced-warm-air oil-, natural-gas-, or propane-fired furnace (downstream series add—on).
The requirements for solid-fuel-fired add-on furnaces also apply to any additional ductwork, controls, and other equipment recommended by the add-on furnace manufacturer and intended to be added on during the installation of the furnace.
The requirements for solid—fuel-fired add—on furnaces do not apply to parallel systems and upstream series add-ons (where the solid—fuel-fired furnace has been added on directly in series at a point before the air enters the existing forced-warm-air furnace).
This Standard also applies to solid-fuel—fired furnaces
(a) intended to be added on directly in series at a point after the warm-air leaves the existing forced-warm-air electric furnace (downstream series addon); and
(b) with a single warm-air discharge meeting the requirements of CSA Standard C22.2 No. 23.
This Standard does not cover fireplaces, incinerators, space heaters or stoves.
The values given in SI (metric) units are to be considered to be the standard. The values given in parentheses are for information only.
