Your wood stove heat shield should be installed anyplace within 36" from a combustible wall to the heat source. The best way to do this is to cut a piece of scrap wood 36" long, place one end against all the edges of the wood burning stove, then place the other end up against the walls.
- It must be affixed to the wall using non-combustible fixings, with an air gap of at least 25mm between the heat shield and the wall.
- The heat shield must be open at both the top and the bottom to allow the flow of cool air between the shield and the wall.

Yes. Clearance should be three times the diameter of the pipe, e.g., a 6-inch pipe needs 18 inches of clearance. Heat shields may be used to reduce the clearance by the same ratio as for the stove. For example, with sheet metal you can reduce the clearance by two-thirds, from 18 inches to 6 inches.
How does a wood stove heat shield work?
A thin metal heat shield is effective because metal is an excellent conductor of heat. The wood stove heats up the metal, and the metal spreads this heat over its entire surface area so that circulating air can keep everything sufficiently cool.

Clearances are calculated in all directions in a straight line. The easiest way to figure out what surfaces a shield needs to cover is to cut a dowel to the rated clearance you're testing.
How far does a Dwarf heat shield go?
Attaching air-cooled heat shields directly to the body of Dwarf stoves using our factory heat shield kit cuts required clearances in half, so 16" from the sides becomes 8", and 18" from the back becomes 9". Similarly, attaching air-cooled heat shields to our single-wall pipe creates a double-wall pipe, which requires 9" clearance to combustibles with the heat shield in between instead of the standard 18".
Why are clearances important?
Pyrolysis - Why Clearances are So Large. Clearances are important because wood stoves get very hot while in operation. Combustible materials that are too close to the stove can heat up past their autoignition temperature, and catch fire. A spark is not required to start a fire, just heat, fuel, and oxygen.
What temperature should a stove be?
To be safe, exposed combustible materials around the stove should never exceed 117 degrees F over ambient temperature, and unexposed areas (under the hearth, for example) should never exceed 90 degrees F over ambient. If you observe potentially combustible materials around a stove discoloring, that can be an indication that pyrolysis is occurring.

So, 18" clearance reduced to 6" with a shield that stands 1" away from the wall would need at least 5" from the shield to the heat source.
Why is clearance violation dangerous?
Clearance violations are an especially dangerous problem because they often don't cause a fire immediately. Sometimes pyrolysis is visible as discoloration or charring on the surface of combustibles, but sometimes the pyrolysis can occur inside a wall. You could use your wood stove with no problems for months or years until one day, your wall catches fire from the inside without warning.
How do I drill a hole in a hardi board?
