Vermont Castings Encore 2550 Installating And Operation Manual page 11

In general, the greatest clearance is required when you
place a stove and its connector with no heat shields
near a wall with no heat shield.
For example, when the Encore is installed parallel to
the rear wall and no shields are used, it must be at least
31" (787 mm) from the wall behind it and at least 24"
(610 mm) from walls on either side.
If the Encore is installed in a corner and no shields
are used, the corners of the stove must be at least 24"
(610 mm) from nearby walls.
The least clearance is required when both the stove
and its connector, as well as the wall, have heat
shields.
When shields are attached to the stove or chimney
connector, they are mounted 1" - 2" (25-51 mm) away
from the stove or connector surface on noncombustible
spacers. Air flowing between the stove (and/or chimney
connector) and nearby shields carries away heat. Do
not block the air flow by filling this empty space with any
insulating material.
The shiny shield surface facing the heat source must be
left unpainted, enabling it to reflect heat back towards
the stove or connector and away from the wall.
Clearances may be reduced only by means approved
by the regulatory authority, and in accordance with the
clearances listed in this manual.
Because of their restricted air flow and heat retention
characteristics, specific construction requirements and
special clearances apply to installations into alcoves.
Refer to the diagrams on Page 10, and contact your
Vermont Castings Dealer for details before beginning
an alcove installation.
NOTE: ALCOVE INSTALLATION OF THE ENCORE
IS NOT PERMITTED IN CANADA.
Stove Heat Shields
The Vermont Castings Encore Rear Heat Shield is one
way to reduce the clearance to the rear wall. The rear
heat shield can be installed on either rear- or top-vent-
ing stoves. However, since the chimney connector
also radiates heat toward the wall in top-venting instal-
lations, you should use a chimney connector shield
whenever you use the rear heat shield on top-venting
stoves.
Clearance reductions with the rear heat shield apply
only to the wall to the rear in parallel installations. Nei-
ther the side clearance requirement nor the clearance
requirement in corner installations may be reduced.

Wall Shields
One way to reduce clearances is with a wall shield
constructed of 24 gauge or heavier sheet metal, or of
another noncombustible material such as 1/2" (13 mm)
insulation board or common brick "laid on flat," with the
3¹⁄₂" (90 mm) side down.
Shields must be spaced out from the combustible
surface 1" (25 mm) on noncombustible spacers, as in
Figure 13. The spacers should not be directly behind
the stove or chimney connector.
Air must be able to flow between the wall and the
shield. At least 50% of the bottom 1" (25 mm) of the
shield should be open and the shield must be open at
the top. Use metal screening, as in Figure 14, to keep
stray objects from falling behind the shield.
The shield for a top-exit stove must extend 10" (254 mm)
above the top of the stove; for a rear exit configura-
tion, the shield must be 36" (914 mm) high. The shield
for the chimney connector must be 30" (762 mm) wide,
centered behind the pipe; for installations that use an
approved prefabricated chimney to pass through the ceil-
ing, the chimney connector shield must stop 1" (25 mm)
below the ceiling.
