Before you begin an installation, be sure that:
•
Your stove and chimney connector will be far enough
from combustible material to meet all clearance require-
ments.
•
The floor protector is large enough and is constructed
properly to meet all requirements.
•
You have all necessary permits from local authorities.
Your local building official is the final authority for approv-
ing your installation as safe and determining that it meets
local and state codes.
The metal label permanently attached to the back of every
Vermont Castings' stove indicates that the stove has been
tested to current UL and ULC standards, and gives the
name of the testing laboratory. Clearance and installation
information also is printed on the label. When the stove
is installed according to the information both on the label
and in this manual, local authorities usually will accept the
label as evidence that the installation meets codes and
can be approved.
However, codes vary in different areas. Before starting
the installation, review your plans with the local building
authority. Your local dealer can provide any additional
information needed.
For any unresolved installation issues, refer to the National
Fire Protection Association's publication ANSI/NFPA 211
Standard for Chimneys, Fireplaces, Vents and Solid Fuel
Burning Appliances. For Canada, the equivalent publica-
tion is CSA CAN-B365 Installation Code for Solid Fuel
Burning Appliances and Equipment. These standards
are the basis for many national codes. They are nationally
recognized and are accepted by most local authorities.
Your local dealer or your local building official may have a
copy of these regulations.
iMpoRTaNT: Failure to follow these installation instruc-
tions may result in a dangerous situation, including a
chimney or house fire. Follow all instructions exactly,
and do not allow makeshift compromises to endanger
property and personal safety.

installation

In some modern, super-insulated homes, there may be
inadequate air supply for combustion because of insuf-
ficient air infiltration into the building. Such air enters a
home through unsealed cracks and openings. Exhaust
fans in kitchens or bathrooms can compete with the stove
for available air and compound the problem.
When poor draft is caused by a low infiltration rate, opening
a ground floor window on the windward side of the house
and near the stove will usually alleviate the problem.
A better solution is to install a permanent outside air supply
to the stove and/or room. In fact, bringing air for combustion
from outside the home directly to the air inlet of the stove
is required for new construction in some areas.
Pressure variations within the house do not affect a stove
equipped with an outside air supply, and improved stove
performance often results. An Outside Air Kit for the Defi-
ant is available from your local dealer.
Altitude affects chimney performance. When using an 8"
oval to 6" flue collar adapter on the Defiant, refer to Fig-
ure 1 for suggested chimney heights at various altitudes.
Chimney height should be measured from the flue collar
to the top of the chimney. The recommended minimum
chimney height is 16' (5 m).
