The Fire Protection Association recommends that the common radiant-type stove must be spaced out by 900mm (36 inches) from a combustible wall. Using a heat shield can reduce the space required to 95mm as stated by HETAS. However, when using a Vlaze heatshield with a Charnwood stove you can reduce this space to just 75mm. It's important that the heat shield is designed properly and that you follow the rated clearance reductions and manufacturers guidelines as your wood stove can get very hot when in operation and combustible materials too close to the stove can catch fire.
