Vermont Casting 2462 Manuel D’Utilisation

5

A prefabricated metal chimney must be one tested and 
listed for use with solid-fuel burning appliances.  
A horizontal connector run should be inclined 1/4” per 
foot (20 mm per meter)  from the stove toward the 
chimney.  The recommended maximum length of a hori-
zontal run is 3 feet (1m) and the total length of chimney 
connector should be no longer than 8 feet (2.5m).

For proper draft and good performance, the chimney 
should extend at least 16’ (5 m) above the flue collar of 
the stove.
The chimney must also extend at least 3’ (900 mm) 
above the highest point where it passes through a roof, 
and at least 2’ (600 mm) higher than any portion of a 
building within 10’ (3 m). (Fig. 2)

The Model 2460 and 2461 heaters should be vented 
into a masonry chimney with a square flue with nomi-
nal flue size of 8” x 8” (200 x 200 mm), or a round flue 
with nominal flue size of 6” (150 mm). The Model 2462 
heater should be vented into a masonry chimney with a 
nominal flue size of 8” x 8” (200 mm x 200 mm) square, 
or 8” (200 mm) round.
Chimney liners larger than 8” x 12” (200 x 300 mm) 
may promote rapid cooling of smoke and reduction in 
draft, especially if they are located outside the home.  
These large chimneys may need to be insulated or 
have their flues relined for proper stove performance.  
Accessories to help make the connection between 
stainless steel chimney liners and the stove are avail-
able through your local dealer.

Fig. 3  The 2/3/10 rule for chimneys.

The chimney connector is the single-wall pipe, or listed 
and approved double-wall pipe that connects the stove 
to the chimney.  The chimney itself is a masonry or 
prefabricated structure that encloses the flue.  Chimney 
connectors are used only to make the connection from 
the stove to the chimney.
Do not pass the chimney connector through a combus-
tible wall or ceiling, or through an attic, a closet or any 
similar concealed space.  If passage through a combus-
tible wall is unavoidable, follow the recommendations in 
the following section on Wall Pass-Throughs.  Keep the 
passage as short and direct as possible, with no more 
than two 90 degree turns.  

You may use either a single-wall steel connector of the 
size and gauge described below, or a listed and ap-
proved double-wall connector.

The single-wall chimney connector should be made of 
24 gauge or heavier steel, and must have a minimum 
internal diameter of  6” (150 mm) for models 2460 and 
2461, or 8” (200 mm) for model 2462.
Install single-wall chimney connector not less than 18” 
(450 mm) from the ceiling.
In cathedral ceiling installations, extend the prefabri-
cated chimney downward to within 8 feet (2.5 meters) 
of the stove.  The entire chimney connector should be 
exposed and accessible for inspection and cleaning.
Do not use galvanized chimney connector; it cannot 
withstand the high temperatures that can be reached 
by smoke and exhaust gases and it may release toxic 
fumes under high heat.
