The low pressure limit values between outside air and living space are determined and documented over the time period of 5 minutes. They hereby should not exceed -by operating firing place and maximal suction performance- the limit value of 4 Pa (8-Pa test by heating plants independent from ambient air). The 4 Pa test can be performed with several ecom flue gas analysers or pressure meters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"class_list":["post-5572","glossar","type-glossar","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.ecom.de\/en\/wp-json\/wp\/v2\/glossar\/5572","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ecom.de\/en\/wp-json\/wp\/v2\/glossar"}],"about":[{"href":"https:\/\/www.ecom.de\/en\/wp-json\/wp\/v2\/types\/glossar"}],"wp:attachment":[{"href":"https:\/\/www.ecom.de\/en\/wp-json\/wp\/v2\/media?parent=5572"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
