Reducing Clearances - Vermont Castings Intrepid II Installation & Operating Manual

Keep the Stove and Connector a Safe Distance from
Surrounding Materials:
Both a stove and its chimney connector radiate heat in all
directions when operating, and dangerous overheating of
nearby combustible materials can occur if they are too close to
the heat. A safe installation requires that adequate clearance
be maintained between the hot stove and its connector and
nearby combustibles.
Clearance is the distance between either your stove
(measured from the back edge of the stove's top plate) or
chimney connector, and nearby walls, floors, the ceiling, and
any other fixed combustible surface. Your stove has special
clearance requirements that have been established after
careful research and testing to UL and ULC standards. These
clearance requirements must be strictly observed.
In addition, furnishings and other combustible materials must
be kept away from the stove as well. In general, a distance of
48" (1220 mm) must be maintained between the stove and
movable combustible items such as drying clothes, furniture,
newspapers, firewood, etc. Keeping those clearance areas
empty assures that nearby surfaces and objects will not
overheat.

Reducing Clearances:

Stove clearances may be reduced by using heat shields
attached to the stove. Chimney connector clearances may
be reduced by using heat shields on single-wall connector,
or by using double-wall connector. Clearances may also be
reduced by using wall shields. All shielding used to reduce
clearances must be listed by a recognized testing laboratory
and approved by the local regulatory body.
Clearance requirements are established for many different
installations. In general, the greatest clearance is required
when you are placing a stove and its connector with no heat
shields near a wall with no heat shield.
For example, when the Intrepid II is installed parallel to the
rear wall and no shielding is used, it must be at least 30"
(760 mm) from the wall behind it and at least 24" (610 mm)
from walls on either side.
If the Intrepid II is installed in a corner and no shields are
used, the corners of the stove must be at least 20" (510 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 non-combustible 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.
Shields are never used on double-wall connectors.
Clearances may be reduced only by means approved by the
regulatory authority, and in accordance with the clearances
listed in this manual.
NOTE: ALCOVE INSTALLATION OF THE INTREPID II IS
NOT PERMITTED IN CANADA.
Stove Heat Shields
The Intrepid II Rear Heat Shield is one way to reduce the
clearance to the rear wall. The rear heat shield may be
installed on either rear- or top-exiting stoves. However, since
the chimney connector also radiates heat toward the wall
in top-exiting installations, either single-wall connector with
connector heat shields, or listed and approved double-wall
chimney connector should be used whenever the rear heat
shield is used on top-exiting stoves.
Clearance reductions with the rear heat shield apply only to
the wall to the rear in parallel installations. Neither the side
clearance requirement nor the clearance requirement in
corner installations may be reduced.
Wall Shields
Clearances may be reduced by using a wall shield constructed
of 24 gauge or heavier sheet metal, or of another non-
combustible material such as 1/2" (13 mm) insulation board
or common brick "laid on flat," with the 3-1/2" (90 mm) side
down. Figure 13 shows such a wall shield.
