These systems require a specific and constant negative pressure for operation. If the chimney draft exceeds the value for optimal draft, the damper of the chimney draft regulator opens, reducing the negative pressure by allowing additional air to flow in. Once the preset value is reached, the damper of the Z4 draft regulator can be closed again. The Z4 draft regulator is made of stainless steel and designed for installation in the chimney wall.\u003cbr\u003e\u003c\/p\u003e  \u003ch3\u003eTechnical data:\u003c\/h3\u003e  \u003cul\u003e  \u003cli\u003eSize: 130 x 190 mm\u003c\/li\u003e  \u003cli\u003eLid dimensions: 15 x 22 cm\u003c\/li\u003e  \u003cli\u003eFrame depth: 6 cm\u003c\/li\u003e  \u003cli\u003efor installation in the chimney wall\u003c\/li\u003e  \u003cli\u003eMaterial: V2A stainless steel 1.4301\u003c\/li\u003e  \u003cli\u003eAutomatically operating secondary air device according to DIN 4795\u003c\/li\u003e  \u003cli\u003eSuitable for oil, gas and all solid fuels\u003c\/li\u003e  \u003cli\u003eControl range 10 - 50 Pa\u003c\/li\u003e  \u003cli\u003ePerformance group 1 - 5\u003c\/li\u003e  \u003cli\u003eWeight: 0.8 kg\u003c\/li\u003e  \u003c\/ul\u003e","brand":"Gema GmbH","offers":[{"title":"Default Title","offer_id":53515462410588,"sku":"ZBGZ4","price":83.96,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/7796\/6428\/files\/zugbegrenzer-z4-130-x-190-mm-2964801.jpg?v=1770693082","url":"https:\/\/si.gemashop.de\/products\/draft-limiter-z4-130-x-190-mm","provider":"GEMA Shop","version":"1.0","type":"link"}
