Flue systems technical guide

Flue gas temperature protection

The flue pipes are approved for fluegas temperatures up to 120 °C.

With Viessmann condensing boilers,internal safeguards ensure that themaximum permissible flue gas temper-ature is not exceeded.

Installation information

■ The component overviews for the dif-ferent types of routing also apply tofloorstanding condensing boilers.

■ Keep flue gas routes short and withthe fewest number of bends possible.

■ Route horizontal connection pipeswith a fall of ≥ 3° (approx. 50 mm/m)towards the boiler.

■ Support horizontal connection pipesat intervals of approx. 1 m.

■ To avoid damage and leaks, isolatethe flue system from sources of vibra-tion (e.g. ventilation systems).

■ Check whether the gaskets in allfemale connections are correctlyseated.

■ Prior to installation, lubricate all gas-kets with the lubricating paste provi-ded.

■ Use only the special gaskets suppliedwith the boiler.

■ Female plug-in connections in theflue gas path must always point in thedirection of flow.

■ Use only the components suppliedwith the Viessmann flue system.

■ Push the pipes into each other with aslight twisting motion.

■ Balanced flue pipes can be trimmedin their assembled state.

Only carry out commissioning whenthe following conditions have been met:■ Unrestricted flow in the flue gas

routes.■ Positive pressure flue system is gas-

tight.■ Inspection port covers checked for

secure and tight seating.■ Apertures for supplying sufficient

combustion air are open and cannotbe closed.

■ All current regulations on installingand commissioning flue systemshave been observed.

DangerLeaking or blocked flue sys-tems, or an inadequate supplyof combustion air can cause lifethreatening poisoning from car-bon monoxide in the flue gas.

Ensure the flue system is ingood working order. Vents forsupplying combustion air mustbe non-closable.

Required tools/equipment

■ Rope for lowering the flue systeminto a shaft (length: Chimney heightplus 3 m)

■ Saw and file for trimming and cham-fering the pipe sections

Tightness test

After installation, flue systems routedthrough a shaft must be tested for tight-ness by the flue gas inspector [checklocal regulations].■ Pressurised flues which are routed

inside buildings and which are notsurrounded by combustion air (openflue) must be pressure-tested.For the pressure test, a leak detectoris used to pump air into the flue,which has been sealed at the top andbottom, until a pressure of 200 Pahas built up. This pressure is main-tained while the volume of air leakingout is established.A leakage rate of up to0.006 l/(s x m2), relative to the inter-nal surface area, is permitted forclassifying a flue as sufficiently gas-tight.

■ In pressurised flues that are surroun-ded by combustion air (room sealed),the tightness can be checked by test-ing the O2 content in the combustionair (annular gap test).The flue is considered sufficientlygas-tight if the O2 content in the com-bustion air does not deviate from thereference value by more than the fol-lowing values. The reference value isestablished following the self-adjust-ment of the test meter:– For flues with general building reg-

ulations approval 0.4 % by vol.– For other flues 0.2 % by vol.

NoteObserve country-specific regulations.

Certification of the balanced flue system

The balanced flue system is CE desig-nated and approved in accordance withEN 14471. See the flue systems techni-cal guide and enclosed "System certifi-cation" labels.

System certification

System certification to EC Gas Applian-ces Directive EU/2009/142/EC in con-junction with PPs flues offered by Sko-berne.

NoteAffix the "System certification" and"Flue system ..." labels clearly visiblenear the flue system or on the boiler.

The labels are supplied with the techni-cal documentation.

Boiler position

The following limitations must beobserved when siting the boiler:■ The boiler is not suitable for external

installation. The position selected forthe installation should be within thebuilding, unless otherwise protectedby a suitable enclosure and mustallow adequate space for installation,servicing and operation of the appli-ance and for air circulation around it.

■ The position must allow for a suitableflue system and terminal position.The boiler must be installed on a flatvertical wall capable of supporting theweight of the appliance and anyancillary equipment when full.

■ Due consideration should be given tothe routing of the condensate drainfrom the chosen position.

■ 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 Insti-tute of Gas Engineers.

■ If the appliance is to be installed in aroom containing a bath or shower,any electrical switch or control utilis-ing mains electricity must be so situ-ated that it cannot be touched by aperson using the bath or shower.Attention is drawn to the require-ments of BS 7671 (the current I.E.EWiring Regulations) and in Scotlandthe electrical provisions of the Build-ing Regulations applicable in Scot-land.

■ A compartment used to enclose theappliance must be designed and con-structed specifically for this purpose.An existing cupboard or compartmentmay be used provided it is modifiedaccordingly. BS 7698:2000 givesdetails of the essential features ofcupboard / compartment design,including airing cupboards. TheVitodens range does not requirecompartment ventilation.

■ Where installation will be in anunusual location, special proceduresmay be necessary. BS 6798 givesdetailed guidance on this aspect.

Installation information

Prior to installation, the local flue gasinspector should check that the shaft tobe used is suitable and permissible[where applicable].Ventilation air ducts with which oil orsolid fuel boilers were previously usedmust not contain any sulphur or sootdeposits on the inner surfaces of thechimney. Sulphur and soot depositscause faults. If thorough cleaning is notpossible, a balanced flue pipe must belaid through the shaft. Alternatively, aseparate balanced flue can be routed.In the installation room, at least oneinspection port must be provided in theflue system for inspection, cleaning andpressure testing (if required). If the flueis not accessible from the roof, a sec-ond inspection port must be providedbehind the chimney cleaning hatch inthe attic.

Provide an inspection port at the baseof the shaft for inspecting the secon-dary ventilation. Safeguard condensatedrainage from the flue to the boiler witha fall of at least 3° (approx. 50 mm/m).The flue system must protrude abovethe roof line. Observe 400 mm protru-sion from the roof parallel to the roofslope according to FeuVo [or local reg-ulations].

If the balanced flue system is routedthrough roof spaces that are not usedas accommodation, run the flue throughan additional metal pipe as protectionagainst mechanical damage(TRGI 2008).

If several roof outlets are installed sideby side: Observe a minimum clearanceof 1.5 m between outlets and to otherbuilding structures (e.g. skylights) inaccordance with TRGI 2008. Observethe clearance of the flue outlet abovethe roof (see diagram). If the ratedheating output is ≥ 50 kW, an above-roof extension is required (seepage 40).
