SAFETY NOTICE:  IF YOUR ENCORE IS NOT PROP-
ERLY INSTALLED,  A HOUSE FIRE MAY RESULT.  
TO REDUCE THE RISK OF FIRE, FOLLOW THE 
INSTALLATION INSTRUCTIONS.  CONTACT LOCAL 
BUILDING OR FIRE OFFICIALS ABOUT RESTRIC-
TIONS AND INSTALLATION INSPECTION REQUIRE-
MENTS IN YOUR AREA.
Before you begin an installation, be sure that:

• 

Your stove and chimney connector will be far 
enough from combustible materials to meet all 
clearance requirements.

• 

The floor protector is large enough and is con-
structed properly to meet all requirements.

• 

You have all necessary permits from local au-
thorities.

Your local building official is the final authority for ap-
proving 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 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 
in most cases 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 publication 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.  

In some modern, super-insulated homes, there is 
inadequate air for combustion because of insufficient 
air infiltration into the building. Such air enters a home 
through unsealed cracks and openings. Exhaust fans 
for kitchen or bath can compete with the stove for avail-
able 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 in the vicinity of the stove will usually 
alleviate the problem.
Another 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 im-
proved stove performance often results. An Outside Air 
Adapter Kit for the Encore is available from your local 
Vermont Castings dealer.

Altitude affects chimney performance.  When using a 
6” flue collar on the Encore, refer to Figure 2 for sug-
gested chimney heights at various altitudes.  Chimney 
height should be measured from the flue collar to the 
top of the chimney.  The recommended minimum chim-
ney height is 16’ (4.9m).
