Why do I need a wall screen?
Most installations in the UK do not require a wall screen as the wall behind the fire is generally made of non-combustible material. For homes that do have combustible walls behind the wood fire, the following is applicable:
Unlike most other wood fires which are able to use a standard shield attached to the flue pipe, the heat output of the Pyroclassic IV is too great and as such requires a separate shield to be attached to a combustible wall surface to make it comply with the clearance standards required.
However, you can install a Pyroclassic IV without wall screens if you chose to use a non-combustible wall board product such as Eterpan, Supalux or Promina board and install it as per the manufacture specifications. Usually this involves ensuring a 25mm air gap is maintained between the wall board and any timber framing.
