    Important Regulatory and Installation Requirements (continued)

    When replacing parts, use originalViessmann or Viessmann approvedreplacement parts.

    For coaxial venting systems only:Venting material to be supplied byViessmann only.

    The venting system must be installedby a licensed professional heatingcontractor familiar with the operationand maintenance of heating appliancesand venting. Before installing thisproduct, ensure that the completeinstallation literature has been read.Failure to follow proper installationprocedures as stated in theseinstructions, including vent pitch andproper appliance connections, mayviolate local, provincial/state, ornational codes and cause unsafeconditions which may lead to severeproperty damage or personal injury.

    The venting system must be installedin accordance with local building coderequirements as well as national codes.For installations in Canada useCAN/CSA-B149.1 Natural GasInstallation Code or CAN/CSA-B149.2Propane Installation Code as applicable;in the U.S. use the National Fuel GasCode ANSI Z223.1 or NFPA Standard54.

    To ensure safe operation of theappliance, Viessmann recommends thatthe system be inspected once a yearby a qualified service technician.

    Every venting system must be plannedand installed for optimum performanceand safety. These InstallationInstructions are designed to help youdetermine venting requirements andlimitations with respect to installation.Please read and follow theseinstructions carefully.

    It is the responsibility of the installer tocontact local building and fire officialsconcerning any installation restrictionsand/or inspection requirements thatmay apply. Permits may be requiredbefore commencement of theinstallation.

    The vent termination for side wall ventinstallations should be located on awall that is least affected by prevailingwinds. High winds may affect boileroperation and/or degrade the exteriorfinish of the wall. They may also causerecirculation of the appliances ownflue products. Recirculation of flueproducts can result in poor combustionand inlet condensation problems. Ifwind is a problem, steps must be takento shield the vent termination from highwinds, such as building a fence orplanting shrubs. Ensure that the totalequivalent vent length is not exceeded.

    Operation with balanced flue usingViessmann supplied coaxial ventsystem

    Side wall vent installations mustinclude Viessmann protective screen.

    Because of its sealed combustionchamber, the Vitodens gas-firedcondensing boiler is suitable foroperation with balanced flue.The Vitodens boiler, flue gas adaptorand parallel adaptor (if used) areapproved together under CSA 4.9.ANSI Z21.13 - 2007 Standard.The venting system components aretested and listed to ULCS636 byIntertek and are marked and labelled onech component.

    Do not mix pipe, fittings, or joiningmethods from different vent systemmanufacturers. Do not use adhesivesof any kind with this venting system.

    The vent length requirements stated inthis manual (starting on page 22 forside wall vent installations and page 31for vertical vent installations) must beobserved.

    The combustion air is supplied and theflue gas discharged via a coaxial doublepipe. Combustion air is fed through thecircular gap between the outeraluminum air intake pipe and the ventpipe. Flue gases are discharged via aninner pipe constructed fromflame-retardant plastic (polypropylenerated for a maximum temperature of230F / 110C).

    Not all inspection authorities require aleak test of the vent-air intake systemin conjunction with the wall-mountedgas-fired boiler during system start-up.In cases where the leak test is notrequired, Viessmann recommends thatthe heating contractor perform asimplified leak test when starting upthe system. For this purpose, it issufficient to measure the CO2concentration in the combustion air ofthe circular gap of the coaxial vent-airintake pipe. The vent pipe is consideredsufficiently leak-proof if the CO2concentration in the combustion air isno higher than 0.2 % and the O2concentration no lower than 20.6 %.If higher CO2 or lower O2 values aremeasured, the flue gas system must bechecked for leaks.

    The coaxial venting material can beextended (without exceeding themaximum equivalent length) beyondthe outside wall of the structure,provided that the coaxial ventingmaterial is installed in an enclosed,insulated and waterproof chase that isacceptable for outdoor installation. Thevent termination location must complywith the instructions and codes statedin this manual.

    Potential gaps between the vent-airintake and the surrounding constructionwhich may cause air, rain or flue gasesto leak into the wall or the building,must be sealed with approvedsealant/caulking to prevent leakage ofany kind.

    The Vitodens 100-W and 200-Wboilers are NOT approved forcommon-venting applications.Do not attempt to common-vent theVitodens 200-W boiler with anyother appliance.

    WARNING

    Failure to ensure that all flue gaseshave been safely vented to theoutdoors can cause propertydamage, severe personal injury, orloss of life. Flue gases may containdeadly carbon monoxide.

    WARNING

    Under certain climatic conditionssome building materials may beaffected by flue products expelled inclose proximity to unprotectedsurfaces. Sealing or shielding of theexposed surfaces with a corrosionresistant material (e.g. aluminumsheeting) may be required to preventstaining or deterioration. Theprotective material should beattached and sealed (if necessary) tothe building before attaching the venttermination. It is stronglyrecommended to install the venttermination on the leeward side ofthe building.

    General Installation Information

    Installation steps (outline)

    Boiler operation in marine environments(damp, salty coastal areas):

    The service life of the boilers exposedmetallic surfaces, such as the casingand fan housing, is directly influencedby proximity to damp and salty marineenvironments. In such areas, higherconcentration levels of chlorides fromsea spray, coupled with relativehumidity, can lead to degradation ofthe exposed metallic surfacesmentioned above. Therefore, it isimperative that boilers installed in suchenvironments not be installed usingdirect vent systems which drawoutdoor air for combustion. Suchboilers must be installed using room airdependent vent systems; i.e. usingroom air for combustion. The indoor airwill have a much lower relativehumidity and, hence, the corrosion willbe minimized.

    H Route vent pipe as directly aspossible and with as few bends aspossible to the boiler.

    H Check proper location of gaskets inall coaxial pipe collars.(Only use supplied parts with thepolypropylene venting system.)Apply moderate amount of suppliedlubricant to slip joint ends of vent andair intake pipe collars.

    H Slide pipes into each other with agentle twisting motion.

    H Condensate must drain from the fluepipe to the boiler. Ensure a suitablegradient of at least 3 (approx. 2 per3.3 ft. / 50 mm per 1 m).

    H Use a hacksaw and sheet metal snipsto cut pipes to length (if necessary).Use a file to smooth rough edges.Pipe must be round and not bent intoan oval shape.

    When cutting pipes to length, deburand clean pipes.

    H For stainless steel and CPVC ventingsystems:In conjunction with theseinstructions, follow the installationinstructions supplied by the specialventing manufacturer.Viessmann Venting SystemInstructions supersede theinstructions supplied by themanufacturer.

    Ensure that the entire ventingsystem is protected from physicaldamages. A damaged ventingsystem may cause unsafeconditions.

    WARNING

    The venting system is approved forindoor installations only.Do not install the venting systemoutdoors.

    Recommended venting practice

    When installing a venting system thefollowing recommended ventingpractices apply:

    H Keep length and number of 90elbows to a minimum.

    H Try not to use back-to-back 90elbows.

    H Use 45 elbows where possible tominimize the number of 90 elbowsin case redirection of flue gas isrequired.

    H The special vent system shall not berouted into, through, or within anyother vent such as an existingmasonry or factory-built chimney.

    Exception:A masonry chimney flue may be usedto route the venting system only if noother appliance is vented in the sameflue.

    Leak test (for coaxial venting systems only)

    Viessmann recommends that theheating contractor perform a simplifiedleak test during boiler start-up. For thispurpose it is sufficient to measure theCO2 concentration of the combustionair in the annular gap of the air intakepipe. The vent pipe is consideredsufficiently leak-proof if a CO2concentration in the combustion air nohigher than 0.2% or anO2 concentration no lower than 20.6%is measured relative to a starting O2concentration of 20.9%.

    If higher CO2 values or lower O2 valuesare measured, inspect the ventingsystem thoroughly.

    Continuous short cycling of the boilercan indicate a leaking venting system.

    Note that the vent pipe adaptor comeswith two measurement ports, one forcombustion air intake measurementand one for flue gas measurement.

    1. ....less than 7 ft./2.13 m above apaved sidewalk or a paved drivewaylocated on public property.

    2. ....within 4 ft./1.2 m horizontallyfrom service regulator vents, electricand gas meters as well as reliefequipment.

    3. ....at least 3 ft./0.9 m above anyforced air inlet located within 10 ft./3 m.

    4. ....less than 1 ft./0.3 m above gradelevel or anticipated snow level(consult local building authorities orlocal weather office). Locate thevent termination in such a way thatit cannot be blocked by snow.

    5. ....within 1 ft./0.3 m of a window ordoor which can be opened in anybuilding, any non-mechanical airsupply inlet to any building or thecombustion inlet of any otherappliance.

    6. ....in areas where condensation maycause problems, such as aboveplanters, patios, or adjacent towindows where flue gases maycause fogging.

    7. ....within 3 ft./0.9 m to the propertyline (advisable, not mandatory;please check with local buildingauthorities and municipal bylaws).

    8. ....at a location where ice formationon the ground can present a hazard.

    9. ....so that the flue gases are directedtoward brickwork, siding, or otherconstruction, in such a manner thatmay cause damage from heat orcondensate from the flue gases.

    10. ....where discharging hot fluegases may cause property damageor personal injury.

    11. ....within 3 ft./0.9 m from aninside corner of outside walls.

    Installation of Anchoring System

    The venting system must be securelysupported by an anchoring systemsuitable for the weight and design ofthe materials employed. To do so, usesupplied mounting clips (see fig. 12,and fig. 13).

    The joints in the horizontal section ofthe Vitodens 200-W venting systemmust be secured with the suppliedsheet metal screws (see fig. 9) toprevent the system from sagging.

    The 4/101.6 mm screws suppliedwith the mounting clip provide wall orceiling support for aHminimum distance of 2/50.8 mmHmaximum distance of 3/82.5 mm(see fig. 13).

    If a longer anchoring system is requireduse brass adaptors M8 x 5/16(supplied) with 5/16 all-threaded rods

    (field supplied) (see fig. 13).

    The venting system must be supportedas outlined by one anchor per straightvent pipe. Viessmann recommends theinstallation of the anchor(s) near thevent joint. See illustration (fig. 5) ofside wall venting layout on page 14 ofthis manual.

    Installation of Support System

    The venting system must be securelysupported by a support system suitablefor the weight and design of thematerials employed.Contact your vent material supplier formore information specific to yourinstallation.

    Supports

    Supports are used to transfer theweight of an installation to the buildingstructure. There are different types ofsupports and their capacity varies witheach type and diameter.The following support types areavailable at your local vent materialsupplier...H anchor plateHwall supportH roof supportH floor supportH suspension band (hanger).

    In addition to the support types listedabove Viessmann offers mounting clips(see fig. 25 and fig. 26) which canbe used in conjunction with the abovesupport types to support the weight ofthe venting system. Please contactViessmann to order.

    Vertical vent systems with horizontalsections must have the joints in thesesections secured with supplied sheetmetal screws (see fig. 25) toprevent the system from sagging.

    The 4/101.6 mm screws suppliedwith the mounting clip provide wall orceiling support for aHminimum distance of 2/50.8 mmHmaximum distance of 3/82.5 mm(see fig. 26).

    If a longer support system is requireduse brass adaptors M8 x 5/16(supplied) with 5/16 all-threaded rods

    (field supplied) (see fig. 26).

    Bracing

    Contact your local vent materialsupplier for more information specificto your installation.

    Braces are required to stabilize aninstallation. There are different typesand their use and spacing vary.The following types of braces areavailable at your local vent materialsupplier...Hwall bandHwall band extensionH guy wire bandH roof brace.

    Exhaust Vent/Air Intake Requirements

    Combustion air supply

    The Vitodens boiler is suitable forsidewall, as well as vertical ventingusing field supplied venting material.The Vitodens 100-W and 200-Wboilers are approved for both directvent (sealed combustion), as well asdirect exhaust (non-sealed combustion)operation in both horizontal and verticalarrangements. For non-sealedcombustion vent systems (i.e. room-airdependent), see appropriate sectionunder Single Wall Venting starting onpage 64 in this manual.

    The boiler must be connected to adirect vent system in which all air forcombustion is taken from the outsideatmosphere and all combustionproducts are discharged safely to theoutdoors.

    The boiler must be vented and suppliedwith combustion air and exhaust ventas described in this section. Ensure thevent and combustion air supply complywith these instructions.

    Inspect all finished exhaust vent/airintake piping to ensure:

    HVent/air intake pipe and fittings are ofapproved material.

    HAcceptable size, length and numberof elbows on combined vent/airintake system.

    H Installation is in accordance withprevailing provisions of local codes.

    H Installation complies with therequirements of these instructions, aswell as the exhaust vent/air intakesuppliers instructions.

    The exhaust vent and combustion airintake system and terminations may beinstalled in one of the following typeterminations (2-pipe system):

    1. Horizontal air intake and exhaustvent pipes

    2. Vertical air intake and exhaust ventpipes

    3. Horizontal air intake pipe and verticalexhaust vent pipe

    * Typically when the boiler is used asa temporary heat source during thebuilding construction phase.

    Do not locate boiler in areas wherehigh dust levels or high humiditylevels are present.

    CAUTION

    Do not install boiler duringconstruction involving drywall orheavy dust of any kind. Dust canaccumulate in the burners and causesooting. Install boiler after all heavydust construction is completed.

    CAUTION*

    If the boiler has been exposed to highdust levels, all burners and the heatexchanger must be cleaned prior touse.

    CAUTION

    If above criteria are not properlyobserved and boiler damage results,any warranty on the complete boilerand related components will be nulland void.

    CAUTION

    Exhaust Vent/Air Intake Requirements (continued)

    General requirements

    The Vitodens 100-W and 200-Wboilers must be located in such a waythat the vent length is as short aspossible and that the vent can berouted as directly (and with as fewbends) as possible.The minimum equivalent vent length is4 ft. / 1.2 m.See tables NO TAG, 40. and 41. formaximum and minimum vent lengths.

    All products of combustion must besafely vented to the outdoors.The Vitodens boiler is not approved forcommon-venting applications. Do notcommon-vent with any other appliance.The Vitodens boiler vents underpositive pressure and is a Category IVboiler.

    Viessmann recommends that the entirevent system be checked by a licensedprofessional heating contractor at leastonce each year following initialinstallation.

    The stainless steel special ventingsystem is completely sealed when fullyassembled. Locking bands are used toreinforce the joints between pipe andfittings.

    Do not install vent pipe in a way thatflue gases flow downwards. Thedirection of flue gas flow must bevertically upwards or horizontal with anupward slope.

    Ensure there is no flue gas leakage intothe area in which the boiler is installed.

    Check joints for leaks with the gassupply turned off and the fan running.Use a soapy solution to check for ventleaks.

    Condensate must drain from the fluepipe to the boiler. Ensure a suitablegradient of at least 3 (approx. 2 per3.3 ft. / 50 mm per 1 m).No condensate trap is required in thevent pipe system.

    5368815

    v2.0

    b

    Failure to ensure that all flue gaseshave been safely vented to theoutdoors can cause property damage,severe personal injury, or loss of life.Flue gases may contain deadly carbonmonoxide.

    WARNING

    Different manufacturers offer anumber of different joint systems andadhesives. Do not mix pipes, fittingsand/or joining methods from differentmanufacturers. Failure to complycould result in leakage, potentiallycausing personal injury or death.

    Exhaust and combustion air pipingmaterial

    Use only the materials listed in table32. entitled Approved materials fortwo-pipe system on page 44 forexhaust, combustion air intake pipeand fittings.

    HCut the pipe end square and removeall burrs and debris from joints andfittings.

    H If using CPVC special vent materialfor exhaust vent pipe andABS/PVC/CPVC for combustion airintake pipe, all joints must be properlycleaned, primed and cemented. Useonly cement and primer approved forthe use with the pipe material. Seetable 32. entitled Approvedmaterials for two-pipe system onpage 44 for approved solvent cementmaterial.

    HNo low point is allowed in theexhaust vent pipe system, unless aproper drain pipe is used to allowcondensate to drain.

    H Route vent pipe as directly aspossible and with as few bends aspossible to the boiler.

    H Condensate must drain from the fluepipe to the boiler. Ensure a suitablegradient of at least 3 (approx. 2 per3.3 ft. / 50 mm per 1 m).

    H Use a hacksaw and sheet metal snipsto cut pipes to length (if necessary).Use a file to smooth rough edges.Pipe must be round and not bent intoan oval shape.

    When cutting pipes to length, deburand clean pipes.

    In conjunction with theseinstructions, follow the installationinstructions supplied by the specialventing manufacturer.Viessmann Venting SystemInstructions supersede theinstructions supplied by themanufacturer.

    HAll piping must be fully supported.Use pipe hangers at a minimum of48 / 1219 mm intervals to preventsagging of the pipe.

    HThe exhaust vent/air intake pipe andfittings must be securely supportedby a support system suitable for theweight and design of the materialemployed. Contact your local ventmaterial supplier for more informationspecific to your installation(s).

    Ensure that the exhaust vent/air intakepipes are properly supported. TheVitodens boiler is not designed tosupport the weight of the exhaustvent/air intake pipe system.

    H Field supplied increaser fittings(transition) should always be insertedin vertical sections of pipe to preventaccumulation of condensate in thevent pipe.

    HThe total equivalent length specifiedfor a two-pipe system is the total ofthe combined length of the exhaustvent/air intake pipe system. Do notexceed these maximum lenghts.

    Vent Requirements - Stainless Steel

    Additional requirements for stainless steel vent pipe material

    Use an AL29-4C special stainlesssteel venting system (UL/ULC listed forcategory IV) for horizontal or verticalventing of the Vitodens boilers.See tables 35 and 36, and contact oneof the suppliers (see listing on right) toorder.

    Prior to installation, check that thecorrect single-wall vent parts wereordered and supplied.

    See table 38 for special parallel/starteradaptor and bird screen modelsrequired for your installation. In case ofdiscrepancies, contact original partssupplier.

    Exhaust vent/air intake connection toboiler

    The vent connection to the Vitodensboiler must be made with the starterstainless steel adaptor (supplied byothers and/or parallel adaptor see table38). The starter adaptors are intendedfor a slip fit and slide into the paralleladaptor with a gentle twisting motion.

    Combustion air intake pipe:

    If the venting system will useCPVC/ABS, PVC plastic pipe forcombustion air intake, a CPVC starteradaptor for use on air intakeconnection to parallel adaptor must beordered from Viessmann (see table38.).The bird screen for the air intaketermination elbow must also be orderedfrom Viessmann.

    Note:The Vitodens boiler has passed thezero inches vent clearance tocombustibles testing requirementsdictated by the Harmonized StandardANSI Z21.13. CSA 4.9.2005 andtherefore is listed for zero clearance tocombustibles when vented with asingle wall special venting system(AL-29-4C material).
