G. Negative Pressure
Negative pressure results from the imbalance of air avail-
able for the fireplace to operate properly. Causes for this
imbalance 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
conditioning.
• Imbalances of the HVAC air handling system.
• Upper level air leaks: recessed lighting, attic hatch
opening, duct leaks.
