To install the heater without legs as a fireplace insert, the floor must be completely noncombustible, such as an unpainted concrete floor over earth.
Many fireplaces do not satisfy the “completely non- combustible” requirement because the brick or con- crete hearth in front of the fireplace opening usually is supported by heavy wooden framing as in Figure 13. Because heat passes readily through brick or concrete, it can easily pass through to the wood. As a result, such fireplace hearths are considered a combustible floor. You may not install a heater on a combustible hearth without legs. Standard leg installations must include the bottom heat shield. The floor protector must also meet standard requirements for freestanding installations.
Floor Protection for Fireplace
Installations with Standard Legs
Fireplace installations with the standard legs and the bottom heat shield must have a floor protector of the same construction as that specified for freestanding in- stallations: 1/4”
(152 mm) from the right side and rear. It must also provide protection beneath any horizontal runs of the chimney connector, including 2” to either side.
Many raised hearths will extend less than the required distance from the front of the heater when it is installed. In such cases, sufficient floor protection, as described above, must be added to extend the hearth 16” (406 mm) [18” (457 mm) in Canada].
Hearth rugs do not satisfy the requirements for floor protection.
Fireplace insert installations also have specific clear- ance requirements to the side walls, side decorative trim, and fireplace mantel. This information is found in
“Fireplace Installation Clearances” in this section.
REMINDER- FIREPLACE INSERT INSTALLATIONS WITHOUT LEGS ARE PERMISSIBLE ONLY IF THE HEARTH IS COMPLETELY NONCOMBUSTIBLE, SUCH AS UNPAINTED CONCRETE OVER EARTH.
Keep the Stove a Safe Distance
From Surrounding Materials
Both a stove and its chimney connector radiate heat in all directions when operating. A safe installation re- quires that adequate clearance be maintained between the stove and nearby combustible materials to ensure that such 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 furnish- ings and other combustible materials 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 drying clothes, furniture, newspapers, firewood, etc. Keeping those clearance areas empty assures that nearby surfaces and objects will not overheat.
Safe Ways To Reduce Clearances
Your stove has specific clearance requirements that have been established through careful research and testing to UL and ULC standards.
Clearance requirements have been established to meet every installation possibility, and they involve the combi- nation of basic variables:
•When the stove has no listed heat shield
•When the stove has a listed heat shield
•When the wall has no heat shield
•When the wall has a heat shield
•When the stove has a
•When the stove has a
In general, the greatest clearance is required when you locate a stove 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 a listed heat shield on the chimney connector as well, or a
Clearances may be reduced only by means approved by the regulatory authority and in accordance with the clearances listed in this manual. The charts and sample installations that follow list all the clearances required for the various installation configurations of Dutchwest Convection Heaters.
