Sealed Combustion Appliances

When we burn natural gas or propane in our homes for heating, creating hot water, or to fuel a fireplace, the byproducts of combustion must safely leave the house. Proper full combustion burning of natural gas produces carbon dioxide, water vapour, nitrogen, carbon monoxide, and nitrogen oxides - products which can pose serious health and safety risks to occupants.

R-2000 Homes in Manitoba use sealed combustion or induced draft gas appliances to virtually eliminate the risk of backdrafting the products of combustion into the home, where they can be ingested.

Sealed combustion, condensing natural gas, and propane furnaces bring in their own air for combustion through one plastic pipe and blow the byproducts of combustion out of the house through a second sealed plastic pipe.

Induced draft natural gas and propane hot water tanks incorporate a fan on top to blow their byproducts of combustion out of the house.

Direct vent natural gas or propane fireplaces and hot water tanks are connected to the exterior by a two concentric metal pipes. The inside pipe acts as the flue to carry the products of combustion outdoors while the outer pipe draws air for the combustion process into the house around the inside flue.
