This vent should always be standing straight up with the vent hole at the top. These come in a few different varieties, most look like a bell, but they all serve one purpose - they let the air out of the radiator, making way for the steam to come in. With some vents, you can use a screwdriver, coin or something flat to turn or twist the notched area at the top of the vent – this controls the amount of air in the radiator. The basic premise is that if you control the amount of air that comes out of the vent, you control how much steam goes in, thus limiting how hot the radiator gets. Please note that if you open or close the vent hole, you need to be patient for a change in heat to occur.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;+&lt;/td&gt;&lt;td style=&quot;color: #222; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;[[file:Steam_Radiator_Vent.jpg&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;|frame|A steam vent&lt;/ins&gt;]] On the opposite end of the radiator, there is an air vent (see picture).
