  • Page 20 FURTHER SPECIFICATIONS TO BE CONSIDERED The central heating cooker works with the combustion chamber in depression; it is essential that the exhaust pipe is hermetically sealed. We recommend using rigid stainless steel pipes, with sealing gaskets having a minimum diameter of 120 mm.
  • Page 21 SOLUTION 2 – UPPER FLUE GAS OUTLET If a “conventional” flue is used to discharge flue gas, make sure it is in good working order and complies with the standards currently in force. If the flue should be too big (internal diameter greater than 14 cm), duct the flue using a stainless steel pipe, properly insulated with rock wool or vermiculite, and sized according to the route.
