C. Negativ e P res s ure
Draft is the pressure difference needed to vent appliances
successfully. C onsiderations for successful draft include:
• Preventing negative pressure
• Location of appliance and chimney
Negativ e pres s ure
results from the imbalance of air avail-
able for the stove to operate properly. C auses 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
• Recessed lighting
• Attic hatch opening
• Duct leaks
T o 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 exh aust eq uipment.
• Ensure furnace and air conditioning return vents are
not located in the immediate vicinity of the appliance,
• 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.
WARNING
• Negative pressure can cause spillage of
combustion fumes, soot and carbon mon-
oxi de.
• Appliance needs to draft properly for
safety.
