    The flue combustion gases are taken from the boiler and terminated at a higher level to the air intake or a different termination location to avoid contaminating the air supply with the flue gas. Elco recommend that single wall plastic flue pipe (PPs) be used for open flue systems.

  • Page 4: Room Sealed System

    Open flue systems continued… When using an open flue system, Elco recommends that an air inlet cover or air filter must be fitted on the air inlet connection on the boiler, to stop any debris entering the air supply and causing issues with the boilers combustion.
