With the Easy Fix kit the wall terminal can be connected to the heater very easily. First the wall plates are put into place; then the heater has to be installed. Then the pipes can be put in between by pushing the shorter pieces of pipe over the longer pieces, and subsequently pushing them back over the outlet pipes of the heater.  

The MDV 80 consists of 1 wall plate for the inside wall and 1 outside wall plate, both provided with a combustion air outlet and a fresh air inlet. Extension pipes (diam. 80). are not provided.
