Negative pressure results from the imbalance of air available
for the appliance to operate properly. It can be strongest in
lower levels of the house.
Causes include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustion air requirements for furnaces, water
appliances 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 such as:
- Recessed lighting
- Attic hatch
- Duct leaks

ISSUES
SOLUTIONS
Odor from appliance
When first operated, this appliance may release an odor for the first several hours. This is
caused by the curing of the paint and the burning off of any oils remaining from manufacturing.
Metallic noise
Noise is caused by metal expanding and contracting as it heats up and cools down, similar to
the sound produced by a furnace or heating duct. This noise does not affect the operation or
longevity of the appliance.
Whirring sound
If the blower has been installed, the blower produces a whirring sound which increases in
volume as the speed is increased.
