INPUT ARTICLE: Article: To gain access to the specific post you want to remove, you’ll first need to detach any fasteners securing the post to a wood fence panel or wire mesh. These fasteners may include:  Nails placed through a wood post into a wood panel. Screws connecting the post to the fence via a detachable panel. Tension bands holding wire mesh to the post. With a shovel, break into the ground surrounding the fence post’s concrete base. Keep digging until you create a half-circle gap between the ground and concrete. If possible, dig a hole that is as deep as the concrete itself, giving the post as much wiggle room as possible. Creating a semi-circular hole will be more than enough for most posts. However, if your pole refuses to budge, try digging out the rest. Your pole will resist at first, but should eventually start to move. Keep wiggling the post until you can move it back and forth with ease, indicating that the ground has lost its hold on the concrete base. Some posts, especially those that were not installed particularly well, can be easily removed by hand. Simply grip the base of the pole and lift up with your legs, pulling it out of the ground. Concrete is incredibly heavy, so make sure to grab a friend or 2 for help. Place a thick block or brick next to your post and set a high lift jack on top of it. Then, wrap 1 end of a thick chain around the base of your post and connect the other end of the chain to the jack. When you’re ready, pump the jack slowly. The additional force will help pull the post out of the ground. If the jack doesn’t provide enough support, try connecting the chain to something even larger like a power lift. To prepare the hole for your replacement post, pull out any remaining wood splinters, concrete slivers, and other unwanted items. If necessary, run the head of a shovel along the inside edge of the hole, pulling out any excess debris and smoothing everything over.

SUMMARY: Disconnect the post from any fence panels or wires. Dig a hole around 1 side of the fence post. Rock the post back and forth to break up the surrounding ground. Lift loose posts up by hand. Use a jack to remove your post if it’s stuck. Clear the hole of any post and concrete remains.

In one sentence, describe what the following article is about: Parts of the fireplace can break or wear down, and it's important to note these before the fireplace malfunctions or causes an emergency fire. While the fireplace is cool, open the damper (seal at the top of the fireplace) and inspect the flue (opening connecting the fireplace to the chimney). The flue should be open and clear of obstructions. Examine the hearth to make sure no bricks are damaged or missing, and that the firebox—the interior of the fireplace—is not cracked or damaged. If you're more comfortable letting professionals inspect your fireplace and chimney, call a local chimney sweep. They will inspect both inside and outside of your house, and inform you if any cleaning or repairs are needed. The chimney cap is at the very peak of the chimney: a small, plate-sized lid that is attached to the top of your chimney pipe to make sure that no small animals or debris fall down the chimney. If it becomes clogged or broken, smoke will not be able to exit the chimney and could back up into your house. Make sure that the cap is in good condition, and is free from cracks, ash buildup, or birds' nests. Since you'll need to climb on top of your roof to do this, make sure to observe safety precautions. Firmly ground your ladder before you begin to ascend. Even if the chimney cap is clear, ash can still build up on the inside of the chimney pipe itself. This presents a risk, as excess buildup can catch on fire and lead to a dangerous and chimney fire. If your chimney has excess internal ash buildup, during summer months, smoky-smelling air can be drawn through the chimney into the house.  To clean a chimney, you'll need a specific set of pipes and brushes that you should be able to purchase at your local hardware store. If you prefer not to clean your own chimney, a local cleaning or maintenance service should be able to do the job for you. Also inspect the chimney flashing (the seal between the chimney and roof). This should be tight and not show any signs of damage or wear. Even if your fireplace seems to be in good shape and has been inspected regularly, you need to be aware of fireplace warning signs. You may smell smoke in the room while a fire is burning, notice damaged wallpaper on the wall by the fireplace (or “hot spots,” where the wall adjacent to the chimney is intensely hot in certain places), or begin to notice rust around the damper or firebox. If you see any of these signs, call a chimney sweep or local fireplace-inspection service before lighting your next fire. You may experience downdrafts when using your fireplace. A downdraft is caused by air rushing down your chimney and pushing smoke and ash out from the fireplace into your home. Your chimney cap should prevent downdrafts, but if they occur frequently, inspect the chimney cap and make sure there are no branches overhanging the top of the chimney, as these can interfere with proper airflow.
Summary: Inspect your fireplace every two years. Keep the chimney cap clean. Clean your chimney annually. Be aware of signs of potential problems with your fireplace.
