Opacity (Visible Smoke); Negative Pressure - Vermont Castings Dauntless FlexBurn Catalytic Owner's Manual

Empty the ash pan regularly, typically every one to three
days. The frequency will vary depending on how you
operate your Dauntless FlexBurn
faster at higher heat outputs.
Removed ash should be placed outdoors in a metal
container with a tight-fitting lid. Keep the closed container of
ash on a noncombustible floor or on the ground, well away
from all combustible materials, pending final disposal. If
the ash is disposed of by burial in soil or otherwise locally
dispersed, it should be kept in the closed container until all
cinders have thoroughly cooled.
!
Never use your household or shop vacuum cleaner to
remove ash from the stove; always remove and dispose
of the ash properly.
F. Opacity (Visible Smoke)
This is the measure of how cleanly your appliance is burning.
Opacity is measured in percent; 100% opacity is when
an object is totally obscured by the smoke column from a
chimney, and 0% opacity means that no smoke column can
be seen. As you become familiar with your appliance, you
should periodically check the opacity. This will allow you to
know how to burn as nearly smoke-free as possible (goal of
0% opacity).
!
Fire Risk
• DO NOT BURN GARBAGE OR FLAMMABLE
FLUIDS SUCH AS GASOLINE, NAPTHA OR
ENGINE OIL.
• Do NOT burn treated wood or wood with salt (driftwood).
• May generate carbon monoxide if burn material other
than wood.
May result in illness or possible death.
!

WARNING
WARNING
Vermont Castings • Dauntless FlexBurn Owner's Manual_R3 • 2020 - ___ • 05/20
!
When burning your first fire, you will experience smoke
and odor from the appliance resulting from the curing
of paint and burning off of any oils remaining from
manufacturing.
OPEN WINDOWS DURING INITIAL BURN TO
DISSIPATE SMOKE AND ODORS!
• Odors may be irritating to sensitive individuals.
• Smoke detectors may activate.
G. Negative Pressure
!
Asphyxiation Risk
• Negative pressure can cause spillage of
combustion fumes, soot and carbon monoxide.
• Appliance needs to draft properly for safety.
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
To minimize the effects of negative air pressure:
• Install outside air to the stove with the intake facing
prevailing winds during the heating season
• Ensure adequate outdoor air for all combustion appliances
and exhaust equipment
• 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 a "sealed can" design
• Attic hatches weather stripped or sealed
• Attic mounted duct work and air handler joints and seams
taped or sealed
