The MICROMAT EC has an excess pressure combustion system that allows the appliance to be exhausted over extended
distances using small OD flue components.
The flue gas temperature is extremely low (typically the same as the flow water temperature), which allows the use of easy
to install PPS (polypropylene) flue pipe and fittings.
The appliance can take combustion air from the room in which it is installed (conventional application) or can be room
sealed (fanned balanced flue) using a concentric flue arrangement of a 70mm PPS flue duct within a 125mm galvanised
metal air duct, finished in off-white RAL 7035. A full range of flue pipe and air duct components including roof and wall
terminals is available from RVR Limited.
