Takes almost any fuel. Four diameters, 140 to 200 mm.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eFull description\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eW3G is the point of this system. Most chimneys are certified either for dry operation at high temperature or for wet operation at low temperature. MULTIKERAM is certified for both: it survives a soot fire and it tolerates the condensate that a modern low-temperature boiler produces.\u003c\/p\u003e\u003cp\u003eIn practice that means the fuel decision is not locked in by the chimney. Wood now, gas in five years, pellets after that — the flue stays. That flexibility is worth more than it looks, because replacing a chimney means opening every floor it passes through.\u003c\/p\u003e\u003cp\u003eIt covers gas and oil boilers (except sealed „turbo” types, which need MULTIKERAM LAS), pellet and wood boilers, mixed burners, fireplaces and stoves. Each metre is one fireclay liner, three insulation boards and three outer blocks.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey benefits\u003c\/strong\u003e\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eW3G certified: soot-fire resistant and moisture insensitive at once\u003c\/li\u003e\n  \u003cli\u003eThe fuel can be changed later without changing the chimney\u003c\/li\u003e\n  \u003cli\u003eGas, oil, pellets, wood, mixed burners, fireplaces and stoves\u003c\/li\u003e\n  \u003cli\u003eFour diameters: 140, 160, 180 and 200 mm\u003c\/li\u003e\n  \u003cli\u003eOne-metre fireclay liners — fewer joints than a three-piece flue\u003c\/li\u003e\n  \u003cli\u003eInsulated, load-bearing concrete outer block\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cstrong\u003eTechnical specifications\u003c\/strong\u003e\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eProduct type: insulated ceramic chimney system\u003c\/li\u003e\n  \u003cli\u003eBrand: Leier\u003c\/li\u003e\n  \u003cli\u003eRange: MULTIKERAM\u003c\/li\u003e\n  \u003cli\u003eCertification: W3G\u003c\/li\u003e\n  \u003cli\u003eFlue diameters: 140, 160, 180 and 200 mm\u003c\/li\u003e\n  \u003cli\u003eOuter dimensions: 35 x 35 cm (140 \/ 160), 40 x 40 cm (180 \/ 200)\u003c\/li\u003e\n  \u003cli\u003eWeight: 103–123 kg per linear metre, depending on diameter\u003c\/li\u003e\n  \u003cli\u003eConsumption per linear metre: 1 fireclay liner, 3 insulation boards, 3 outer blocks\u003c\/li\u003e\n  \u003cli\u003eUse: gas, oil, pellet, wood and mixed-fuel appliances — not sealed „turbo” boilers\u003c\/li\u003e\n  \u003cli\u003eSold by: linear metre\u003c\/li\u003e\n  \u003cli\u003eDelivery: made to order, subject to supplier stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cstrong\u003eRecommendation\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eSealed-combustion „turbo” and condensing boilers need a concentric air\/flue system — that is MULTIKERAM LAS, not this one. Everything else, MULTIKERAM handles. Size the flue from Leier's sizing diagram using the appliance output and the useful height. If the fuel is undecided, this is the system to build: the price gap against LSK is small next to the cost of replacing a chimney that turns out to be the wrong class.\u003c\/p\u003e","brand":"Leier","offers":[{"title":"140 mm","offer_id":57161659875706,"sku":"HGM-CS-LIR-MTK-14","price":0.0,"currency_code":"RON","in_stock":true},{"title":"160 mm","offer_id":57161659908474,"sku":"HGM-CS-LIR-MTK-16","price":0.0,"currency_code":"RON","in_stock":true},{"title":"180 mm","offer_id":57161659941242,"sku":"HGM-CS-LIR-MTK-18","price":0.0,"currency_code":"RON","in_stock":true},{"title":"200 mm","offer_id":57161659974010,"sku":"HGM-CS-LIR-MTK-20","price":0.0,"currency_code":"RON","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0943\/5050\/8410\/files\/MULTIKERAM.webp?v=1786606574","url":"https:\/\/heligom.com\/en\/products\/leier-multikeram-chimney-system","provider":"HELIGOM","version":"1.0","type":"link"}
