Clearance to Surrounding

Intrepid 1640 Woodburning Stove

6.If the chimney exits the mobile home through a wall at a point 7’ (2.1m) or less above the ground level on which the mobile home is located, a guard or other noncombustible enclosure must be fitted at the point of exit and extend up to a height of 7’ (2.1m). Any openings in this guard must be smaller than 3/4” (19mm).

7.Check all local building codes, specifically those related to mobile homes. Other requirements may be applicable to chimney system removal for trans- portation of the mobile home.

WARNING: Do not install the Intrepid in a sleeping room or hallway.

CAUTION: The structural integrity of the mobile home roof, floor, walls and ceiling must be main- tained.

Clearance to Surrounding

Combustible Materials

When the stove is operating, both the stoveplate and the chimney connector radiate heat in all directions. A safe installation requires that adequate clearance be maintained between the stove and nearby combustible materials to ensure that those materials do not overheat.

Clearance is the distance between either your stove or chimney connector, and nearby walls, floors, the ceiling, and any other fixed combustible surface. Keep furnishings and other combustible materials away from the stove as well. In general, a distance of 48" (1219mm) must be maintained between the stove and moveable combustible items such as drying clothes, furniture, newspapers, firewood, etc. Keep this area empty of any combustible material.

Safe Ways To Reduce Clearances

The Intrepid clearance requirements, listed and diagramed on Pages 14-15, have been established through testing to UL and ULC standards to meet most installation configurations. These involve four basic variables:

When the stove has no listed heat shield in- stalled.

When the stove does have a listed heat shield mounted on it.

When the wall has no listed heat shield installed.

When the wall does have a listed heat shield mounted on it.

In general, the greatest clearance is required when the stove will be positioned with no heat shield near a wall with no heat shield. The least clearance is required when both the stove and the wall have heat shields.

Reducing a stove clearance may require installation of a listed heat shield on the chimney connector as well.

Clearances may be reduced only by means approved by the regulatory authority, or in accordance with the clearances listed in this manual.

When determining clearance, always measure from the top plate of the stove, or, from the chimney connector itself, to the adjacent combustible surface. Do not measure from the heat shields of the stove or connec- tor to the combustible surface.

Wall Shields

Wall shields should be constructed of 24 gauge or heavier sheet metal, or another noncombustible mate- rial such as 1/2" (13mm) insulation board or common brick "laid on flat," with the 3¹⁄₂" (89mm) side down.

Shields must be spaced out from the combustible surface 1" (25mm) on noncombustible spacers. The spacers should not be directly behind the stove or chimney connector. (Fig. 16)

Air must be able to flow between the wall and the shield. At least 50% of the bottom 1" (25mm) of the shield should be open and the shield must be open at the top.
