With a few onsite meetings and discussions with the design team it was discovered that the existing windshield structure was far taller than required. After carrying out all necessary calculations including BS EN13084-7 and 1090 ex class 2 and whilst adhering to all relevant standards including UP10 and Clean Air Act, John J Doyle Ltd were able to decrease the height of the new windshield by almost half.
As the existing boilers have been in place for many years, we opted to increase the flue diameters in order to future proof the installation should any of the existing boilers require replacement.
The existing structure was safety dismantled and removed from site within a day when the pupils were absent in order to help with health and safety.
New holding down bolts were chemically anchored and allowed to cure for 24-48hrs prior to the new structure arriving.
The new structure was safely landed and installed all within a few hours, again on a day when the pupils were absent for with health and safety in consideration.
All internal Dinak DWJ 316L stainless steel flues were installed with test points and at least a 3Degree fall to allow for any condensation to be correctly drained away.
New box flashing was installed where the new structure protrudes through the boiler house.
The overall installation, from dismantling to commissioning was carried out within 7 days.
All chimney and flue products were supplied and installed CE Marked and compliant with European and regional standards.
