Designation:E277814Standard Specification forCustom Tiled/Mortared Masonry Heaters(Stoves)1This standard is issued under the fixed designation E2778;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification contains specifications for the dimen-sioning of custom tiled/mortared masonry heaters(stoves).Thecustom tiled/mortared masonry heaters(stoves)are individu-ally technically calculated and constructed.This informationcan be used for log(cordwood)wood-fired masonry heatersthat burn one fuel load per storage period with a maximum loadbetween 10 and 40 kg and a storage period(nominal heatingtime)between 8 and 24 h per EN 15544.1.2 This specification is valid for masonry heaters equippedwith fireclay as interior material with an apparent densitybetween 1750 and 2200 kg/m,a degree of porosity 18 up to33%by volume,and a heat conductivity from 0.65 up to0.90 WmK(temperature range 20 to 400C)per EN 15544.1.3 This specification is valid for masonry heaters withsidewise combustion air supply of the combustion chamber.1.4 This specification is not valid for masonry heaterscombined with water heat exchangers for central heating orother heat-absorbing elements such as glass plates greater than16of the combustion chamber surface,open water tanks,andso forth.It is also not valid for masonry heaters combined withheating/fireplace elements in accordance with EN 13229.Furthermore,this specification is not valid for mass-producedprefabricated or partly prefabricated slow heat release appli-ances according to EN 15250.1.5 The calculation method of this specification is used toestablish emissions and energy efficiency when burning logwood or wood briquettes according to the manufacturers orbuilders manual.1.6 Clearance to CombustiblesWhen a masonry heater isconstructed according to this specification,the clearance tocombustibles shall be in accordance with TRVB 105 or otherappropriate standards.1.7 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.1.8 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E631 Terminology of Building ConstructionsE1602 Guide for Construction of Solid Fuel Burning Ma-sonry Heaters2.2 EN Standards:3EN 13229 Inset appliances including open fires fired by solidfuelsRequirements and test methodsEN 133841 ChimneysThermal and fluid dynamic calcu-lation methodsPart 1:Chimneys serving one applianceEN 15250 Slow heat release appliances fired by solid fuelRequirements and test methodsEN 15544 One off Kachelgrundfen/Putzgrundfen tiled/mortared(sic)stoves:Calculation methods2.3 Austrian National Fire Service Association Standard:4TRVB 105 Fireplaces for Solid Fuels3.Terminology3.1 Definitions:Terms used in this specification are definedin Terminology E631.3.2 Masonry heaters are also known by the following wordsand terms and are further explained in Guide E1602;Kachelofen,Kakelugn,grundofen,Kachelgrundfen,Putzgrundfen,and slow heat release appliance.4.Classification4.1 Nominal Heat OutputThe nominal heat output shall bespecified.4.2 Load of Fuel:1This specification is under the jurisdiction of ASTM Committee E06 onPerformance of Buildings and is the direct responsibility of Subcommittee E06.54on Solid Fuel Burning Appliances.Current edition approved Oct.1,2014.Published October 2014.DOI:10.1520/E277814.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from Deutsches Institut fur Normung e.V.(DIN),Burggrafenstrasse 6,10787,Berlin,Germany,http:/www.din.de.4Available from sterreichischer Bundes Feuerwehr Verband(BFV),Voit-gasse 4,1220 Wien,Austria,http:/www.bundesfeuerwehrverband.at/shop/contact.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.2.1 Maximum LoadThe maximum load of fuel is calcu-lated per EN 15544.4.2.2 Minimum LoadThe minimum load is fixed at 50%of the maximum load per EN 15544.mBmin50.5!mB!(1)where:mB=maximum load(kg),andmBmin=minimum load(kg).4.3 Design of the Essential Dimensions:4.3.1 Combustion Chamber DimensionsThe design of thedimensions of the combustion chamber is necessary because,on one hand,enough room to place the fuel in it is needed and,on the other hand,the requirements for a clean combustionhave to be fulfilled.4.3.1.1 Combustion C
