HAMWORTHY HEATING LTD51FLEET H series 500001212/FAPPENDIX C - FLUE DATA - Natural GasC1.0 FLUE SYSTEM1. Detailed recommendations for flue systems are given in BS 6644, and IGE/UP/10. All flue discharges for plantexceeding 150kW output must comply with the third edition of the 1956 Clean Air Act Memorandum.WARNING: THE FLUE DISCHARGE FROM A FLEET BOILER WILL GENERATE A PLUMEAT THE TERMINAL EXIT. THIS MUST BE CONSIDERED WITH REGARD TO TERMINALLOCATION AND ADJACENT BUILDING FABRIC.FOR ALL B23 INSTALLATIONS THE HHL SUPPLIED AIR INLET FILTER (Pt. No. 532812008) MUST BEFITTEDC1.1 General RequirementsThe Fleet boilers are designed to be used with natural draught or room sealed flues. Flue systems should bedesigned in accordance with regulations and with reference to BS 6644 and IGE/UP/10.The following points should be noted:a. Due to the high thermal efficiency of the boiler, condensation will occur in the flue. It is strongly recommendedthat the design of the flue system recognises this. HHL supply plastic flue components and suitable terminals todischarge the flue gases safely. The Fleet flue systems supplied by Hamworthy are non UV stabilised polypropyleneand are therefore suitable for internal use only. For external flue runs and termination, either use the dedicated kitssupplied by Hamworthy or refer to a chimney specialist .b. Care should be taken to ensure that the flue is installed such that any condensation is continuously drained.Any flue system with a horizontal section should have a maximum slope of 3° upwards in the direction of theexhaust gas flow. All joints should be such that any condensation is directed back down the slope to an opendrain connection in the flue. The drain pipe must be manufactured from a corrosion resistant material and at least15mm diameter. It must have a fall of at least 3° (approx. 50mm/meter) and connect to a drain via a waste trap.c. Boiler flue outlet sizes - A flue system designed with the same diameter as the boiler flue outlet may not providesatisfactory performance in all applications. Consideration must be given to the correct calculation of the requiredflue size. If in any doubt consult Hamworthy Heating Ltd who can supply a full flue design and installation service.C1.2 Waste Gas Volume and Temperature.It is recommended that the volume and temperature of the waste gases used for design of the flue system are asgiven in the above tables.* Note:- Flue gas volumes are corrected to a flue gas temperature of 15°C and barometric pressure of1013.25mbar.FLUE DATA per boiler module BOILER MODELF40H F50H F60H F70HFlue connections (concentric) - mm 80/125Approx.
