Vermont Castings Intrepid Multi-Fuel

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 moveable combustible items such as dry- ing clothes, furniture, newspapers, firewood, etc. Keep- ing 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. Clear- ances 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 differ- ent installations. In general, the greatest clearance is required when you are placing a stove and its connec- tor with no heat shields near a wall with no heat shield.

For example, when the Intrepid Multi-Fuel 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 Multi-Fuel 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” (25-50mm) away from the stove or connector surface on noncombustible spacers. Air flowing between the stove (and/or chimney connector) and nearby shields carries heat away. Do not block the air flow by filling this empty space with any insulating material.

The shiny surface facing the heat source must be left unpainted, enabling heat to reflect 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.

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 12, and contact your Vermont Castings dealer for details before beginning an alcove installation.

Stove Heat Shields

The Vermont Castings Intrepid Multi-Fuel 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-exit- ing installations, either single-wall connector with con- nector 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. Nei- ther 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 noncombustible material such as 1/2” (13 mm) insulation board or common brick “laid on flat,” with the 3¹⁄₂" (90 mm) side down. Figure 12 shows such a wall shield.

Shields must be spaced out from the combustible surface 1" (25 mm) on noncombustible spacers. The spacers should not be directly behind the stove or chim- ney 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. (Fig. 12)

The wall shield for a stove must extend 10” (250 mm) above the top of the stove, or a height of 35” (890 mm). The wall shield for the chimney connector must be 28” (710 mm) wide, centered behind the connector; for installations that use an approved prefabricated chim- ney to pass through the ceiling, the chimney connector shield used with single-wall connector must stop 1” (25 mm) below the ceiling.

Chimney Connector Clearance Reductions

Chimney connector clearances may be reduced by using heat shields on single-wall connector or by using double-wall connector. One of these methods should be used whenever the rear heat shield is used in top- exit installations, or in any other situation when it is necessary to protect nearby combustibles from the heat of the chimney connector. The ceiling above horizontal runs of chimney connector must be protected as well if the clearance is inadequate. Refer to the Clearance Charts.
