R

C. Negative Pressure

Draft is the pressure difference needed to vent appliances successfully. Considerations for successful draft include:

•Preventing negative pressure

•Location of appliance and chimney

Negative pressure results from the imbalance of air avail- able for the stove to operate properly. Causes for this imbal- ance include:

•Exhaust fans (kitchen, bath) etc.)

•Range hoods

•Combustion air requirements for furnaces, water heaters and other combustion appliances

•Clothes dryers

•Location of return-air vents to furnace or air condi- tioning

•Imbalances of HVAC air handling system

•Upper level air leaks

To minimize the affects of negative air pressure the following must be considered:

•Install the outside air kit. Install the intake on the side of the house towards prevailing winds during the heating season.

•Ensure adequate outdoor air is supplied for combus- tion appliances and exhaust equipment.

•Ensure furnace and air conditioning return vents are not located in the immediate vicinity of the appli- ance,

•Avoid installing the appliance near doors, walkways or small isolated spaces.

•Recessed lighting should be of “sealed can” design; attic hatches weather stripped or sealed; and attic mounted ductwork and air handler joints and seams taped or sealed.

•Recessed lighting

•Attic hatch opening

•Duct leaks

WARNING

Asphyxiation Risk.

•Negative pressure can cause spillage of com- bustion fumes, soot and carbon monoxide.

•Appliance needs to draft properly for safety.
