Equipment Airtherm have recently designed, supplied and installed a complete twin wall
stainless steel flue system serving each MHS Adinox ADI LT 200 modulating boiler
at Oakham Primary School in Dudley in the West Midlands.
■ MHS ADI LT
The existing cast iron boilers were removed by the contractor during the School
summer shut-down, working on a tight program the MHS high efficiency boilers
were installed followed by the installation of our flue system. All of the plant was
commissioned in time for the return of the pupils to enter a new begging.
Application
The flue system installed was designed to completely evacuate the products
■ High Efficiency Condensing combustion taking into account for the over-pressure from each appliance. Each
primary flue incorporated a volume control damper and draft regulator in the event
of unstable operation. The complete system had a 30 fall back to the appliance to
allow condense to vacate and drain from the flue.
