We were asked to design, supply and install a new flue system to suit 3No. 770kW gas condensing boilers.
At design stage, we carried out the flue sizing and height calculations inhouse to determine the overall flue diameter and required height to comply with regulations set out by Clean air act and IGEM UP10. By carrying out these calculations, it confirmed that we could remove the existing flue structure from site and follow a new flue route.
A crane was hired to remove the existing structure and flues from site on a weekend to prevent any health and safety concerns with pupils and teachers within the vicinity.
Once the structure was removed, John J Doyle was able to install the flues as per the new route set out at design stage. Each flue rises to a high level within the boiler house around existing services to exit the boiler house wall at high level. Due to the positioning of the new flues, a specialised ‘spider’ MEWP was required to install each flue to high level externally.
Installation of the flues were complete over a 5-day period.
