Heat Shields when installation wood burning Stoves
If the appliance selection criteria and heat shield construction caveats as stated above are met, then the clearance distances to combustible materials as stated by the appliance manufacturer can be reduced to a minimum distance of 95mm from the rear of the appliance to the front face of the heat shield when installed at 90° angle parallel to two internal walls. If the appliance installation is at an angle of 45° to each to each wall, then these distances may be reduced to no less that 65mm from the nearest point of the appliance to the front face of the heat shield as stated.
Important installation points to meet the heat shielding installation caveats of BS8303 include:
An air gap of 25mm is maintained at all times between the rear face of the heat shield and front face of the protected combustible material
Clearance distances from the size of the appliance to the front face of the appliance shield when installed in a 90° configuration is a minimum of 95mm
The shield extends to at least the extremities of the hearth, and at least 300mm above the top surface of the appliance
There shall be no protrusions above the shield to hinder flow of cool air behind (i.e shelves)
