To help improve the draw on our open fireplace, we always warm up the chimney before each fire. As we use newspaper as our fire starter, we simply take another sheet of newspaper, roll it up and light it at end, place it within the top area of our fireplace and leave it to burn through By increasing the height of the fire grate, the fire is closer to the chimney channel, as a result of which, the chimney flue becomes warmer and the draft will improve immediately. You can test the effect of this by raising the fireplace grate or the fire basket with stones Fireplace Product's Reece Toscani shows you how to warm up your chimney before you use it, to ensure smoke and gases are drawn up the chimney. www.fireplacep..

Put the grill in cycle 0 (turn the unit on), and tap lightly on the auger tube with either a hammer, or a similar device. Sometimes this is enough to free up whatever is jamming the auger. If the auger hasn't fed any pellets by cycle 1, switch off the grill This will increase the heat in the chimney and increase draw. 4.

The angle of the flue should be 90 degrees or directly perpendicular to ground level if possible. However, it is possible to come off of this vertical by as much as 30 degrees.

In the Ahrens method, there's a second step where. The home will actually draw air down the basement chimney flues, needed to replace the air lost above the neutral pressure plane. This is known as a chimney downdraft. Chimney downdrafts could be caused by external forces, i.e., wind, or internal forces, i.e., positive/negative air pressure zones
The chimney needs to draw in outside air to start and maintain a fire in the fireplace. When there is insufficient oxygen, the negative air pressure can cause chimney draft problems, including a smoky fireplace. It typically occurs in homes with airtight insulation.

This process will increase the speed of those gases escaping by keeping the flue gases warm and subsequently reduce the chance of condensation forming on the liner Include more details such as a television over the mantle, extend the chimney higher to achieve the draw your site requires, then cap it off with a spark-arresting chimney cap in black, stainless, or copper.

This pull, called draft, is created by hot gases rising through the chimney trying.
