General installation instructionsEngineeringPrior to the installation check that themaximum possible flue length inaccordance with the technical guide forthe respective boiler will not be exceeded.Flue gas temperature protectionThe flues are approved for flue gastemperatures up to 120°CMeasures inside the Viessmann condensingboilers ensure that the maximumpermissible flue gas temperature will neverbe exceeded.Installation informationn The component overviews for the typesof routing also apply to the Vitocrossal300 and the Vitoladens 300-T.n Keep flue paths as short as possible withthe fewest number of bends possible.n Check the gaskets in all femaleconnections.n Use only the special gaskets suppliedwith the boiler.n Plug-in fem. connections in the flue mustalways point in the flow direction.n Only use the components supplied withthe PP flue gas system.n Twist the pipes slightly whilst pushingthem in.n Inner and outer pipe can be trimmed tothe same length.Required tools/equipmentn Rope for lowering the flue gas systeminto a duct (length: chimney height plus 3metres).n Saw and file for trimming and chamferingthe pipe sections.n Power drill for securing the duct cover andthe support rail.25458 035 GB

General installation instructions (cont.)Leak/soundness testFlue gas system with Building Regulations approval -Routing through a ductAfter their installation, flue gas systemsrouted through a duct must be tested forsoundness by a competent person as perthe Building regulations.n Pressurised flues inside buildings that arenot surrounded by combustion air (openflue) must be pressure tested.To pressure test a flue, air is pumped intothe flue that has been sealed at the topand bottom using a flue test device, untila pressure of 200 Pa has built. Whilstmaintaining this pressure, the volumeof air that escapes through leaks isestablished.Up to a leakage rate of 0,006 litres/ (s xm 2 ), relative to the internal surface area,is considered as indication that the flue issound.n In pressurised flue gas systems that aresurrounded by combustion air (balanceflue), the soundness can be checked bytesting the O 2content in the combustionair (annular gap test).The flue is reckoned to be sufficientlysound if the O 2content in the combustionair deviates by no more than the followingvalues from the reference value. Thereference value results after the selfadjustmentof the test equipment:– for flues with general BuildingRegulations approval 0.4% by vol.– for other flues 0.2% by vol.Flue gas systems as technical units with Vitodens and Vitoladens5458 035 GBn Balanced flue roof outlet (C33x)n Balanced flue external wall terminal (C13x)n Routing over external walls (C53x)n Separate ventilation and flue gas routing(C53x)We recommend that a simple soundnesstest is carried out during the commissioningof your system. For this it would besufficient to check the CO 2concentration inthe combustion air at the annular gap of thebalanced flue pipe. The flue pipe is deemedto be sound if the CO 2concentration in thecombustion air is no higher than 0.2% orthe O 2concentration is at least 20.6%.If higher CO 2or lower O 2values aremeasured, check the flue system forsoundness.3

Installation requirementsStatutory requirementsThe appliance is suitable only for installation in GB and IE and should be installed in accordancewith the rules in force. In GB a Gas Safe Registered Installer must carry out the installation. Itmust be carried out in accordance with the relevant requirements of the:Gas safety (installation and use) regulations (current issue)It is in your own interest and safety to ensure that the law is complied with.In addition to the above regulations, thisappliance must be installed in accordancewith the current IEE Wiring Regulationsfor electrical installation (BS 7671), localBuilding Regulations, the Building Standards(Scotland) (Consolidation) Regulations, byelaws of the local water undertaking andHealth and Safety Document NO. 635 ‘TheElectricity at Work regulations 1989’In Ireland (IE), the installation must becarried out by a Competent Personand installed in accordance with thecurrent edition if I.S.813 “DomesticGas Installations”, The current BuildingRegulations and references should bemade to the current ETCI rules for electricalinstallation.It should also be in accordance with therelevant recommendations in the currenteditions of the following British Standardsand Codes of Practice: BS 5449, BS 5546,BS 5440:1, BS 5440:2, BS 6798, BS 7593,BS 6891, IGE/UP/7 and IS 813 for IE.All Registered installers are required tonotify building control when they haveinstalled or exchanged a gas appliance ina residential dwelling, this can be done viaGas Safe.Gas Safe will then issue either a BuildingCompliance Certificate (for England andWales) or a Declaration of Safety (Scotland,Northern Island, Isle of Man or appliancesout of the scope of Building Regulations)to the homeowner, which will confirmthat the work has been carried out by acompetent Gas Safe Registered Installer.This document will be used to form part ofthe Home Information Pack (HIP).!Please noteManufacturers instructions must notbe taken in any way as overridingstatutory obligations.Boiler PositionThe following limitations must be observedwhen siting the boiler:n The boiler is not suitable for externalinstallation. The position selected for theinstallation should be within the building,unless otherwise protected by a suitableenclosure and must allow adequate spacefor installation, servicing and operationof the appliance and for air circulationaround it.4n The position must allow for a suitable fluesystem and terminal position. The boilermust be installed on a flat vertical wallcapable of supporting the weight of theappliance and any ancillary equipmentwhen full.n Due consideration should be given to therouting of the condensate drain from thechosen position.n If the boiler is to be fitted in a timberframed building it should be fitted inaccordance with ige/up/7. If in doubtadvice must be sought from the Instituteof Gas Engineers.5458 035 GB 08/2007

Thefollowing notes are for general guidance.n The boiler must be installed so that theterminal is exposed to external air.n It is important that the position of theterminal allows free passage of air acrossit at all times.n It is essential to ensure that products ofcombustion discharging from the terminalcannot re-enter the building or any otheradjacent building, through ventilators,windows, doors, other sources of naturalair infiltration or forced ventilation / airconditioning.n The minimum acceptable dimensionsfrom the terminal to obstruction andventilation openings are specified above(BS 5440 Part 1).n If the terminal discharges into a pathwayor passageway check that combustionproducts will not cause nuisance andthat the terminal will not obstruct thepassageway.n Where the lowest part of the terminalis fitted within 850 mm of a plastic orpainted gutter, or 450 mm of paintedeaves, an aluminium shield at least 750mm long must be fitted to the undersideof the painted surface.n Where the terminal is fitted within 850mm of a plastic or painted gutter, or 450mm of painted eaves, an aluminiumshield at least 750mm long must be fittedto the underside of the painted surface.n The air inlet / flue outlet duct must notbe closer that 25 mm to combustiblematerial.n Due to the high efficiency of the boilerthe terminal may emit a plume of vapour.This is normal but positions wherethis would cause a nuisance should beavoided.5458 035 GB 08/20077

Routing through a ductInstallation InformationPrior to installation, the competentperson should check that the appropriateflue routing is suitable and meets theappropriate requirements. If the flue systemis routed within a duct then the appropriateinspection hatches must be provided, forinspection and cleaning as well for testingthe pressure (if required). If the flue pipeis inaccessible from the roof, a secondinspection aperture must be provided in theattic behind the chimney cleaning hatch.Provide an inspection aperture at the baseof the duct for checking the secondaryventilation. The condensate drainage fromthe flue to the boiler must be ensuredthrough a gradient of at least 3° (approx.50 mm/m).Route the flue over the roof (observethe roof clearance parallel to the roofinclination 400 mm according to thebuilding regulation.105458 035 GB
