How to check if you have an MK1 or Mk2 model stove?
If you're unsure whether your Clock Blithfield 5kW or Clock Blithfield Compact 5kW is an MK1 or MK2 model, there is one easy way to find out.
Look inside your stove at the back wall. If yours is a MK1 model, there will be a black tertiary air bar (black horizontal strip) like the photo opposite. However, if yours is an MK2 model, there will be no black air bar present.
