G. Clearance to Combustibles

Keep the Stove a Safe Distance From Surrounding 

Materials

Both a stove and its chimney connector radiate heat in all 

directions when operating, and nearby combustible materials 

can overheat dangerously if they are too close to the heat 

source. 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  or 

chimney  connector,  and  nearby  walls,  floors,  the  ceiling, 

and any other fixed combustible surface. This appliance has 

specific clearance requirements that have been established 

after careful research and testing. These clearance 

requirements must be strictly observed.

In addition, keep furnishings and other combustible materials 

away from the stove. In general, a distance of 48" (1219 

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. 

Safe Ways to Reduce Clearances

Clearance  requirements  are  established  to  meet  every 

installation possibility, and they involve the combination of 

these variables:

•  When the stove pipe has no listed heat shield mounted 

on it.

•  When the wall has no heat shield mounted on it.
•  When the wall has a heat shield mounted on it.
•  When the wall and stove pipe have heat shields.

In general, the greatest clearance is required when you place 

a stove and its connector near a wall with no heat shield. 

Clearances may be reduced only by means approved by the 

regulatory authority, and in accordance with the clearances 

listed in this manual. Refer to the clearance chart for approved 

clearance reduction specifications. 

NOTE: Installation of this appliance is not permitted in 

alcoves.
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 such as Durock

®

 or Wonderboard

®

, or common brick 

“laid on flat,” with the 3-1/2" (90 mm) side down.

Shields must be spaced out from the combustible surface 1" 

(25 mm) on noncombustible spacers, as in Figure 2.11. 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 must be 

open, and the shield must be open at the top. Metal screening 

across the top will keep small stray objects from being trapped 

behind the shield, Figure 2.11.

Figure 2.11

 - Approved wall shield construction.

The shield must be a minimum of 48" (1219 mm) tall, and 

must extend at least 19" (483 mm) higher than the top of the 

stove, whichever is higher. The shield behind the chimney 

connector must be 30" (760 mm) wide, centered behind the 

pipe; for installations that use an approved prefabricated 

chimney to pass through the ceiling, the shield behind the 

chimney connector must stop 1" (25 mm) below the ceiling. 

With 8" connections and chimneys, because of potentially 

higher  pipe  temperatures,  the  shield  must  extend  the  full 

height of the wall (up to 9’ (2.7 m)) and stop 1" (25 mm) 

below the ceiling.

Fireplace and Mantel Trim Shields

A fireplace installation requires special clearance between 

the side of the stove and the right and left walls, between the 

side of the stove and the decorative side trim on the fireplace 

face, and between the top of the stove and the mantel.

Figure 2.14

 - Parallel installation, vertical chimney connector, two 

wall shields. Reduced clearances for both rear and side walls. Wall 

shields may meet at corner if desired. Shielding for connector is 

centered behind connector.
