You should never block both the top and bottom of your chimney. Proper airflow is essential because the temperature inside the chimney will still fluctuate as your house warms and cools. Moisture can build up without ventilation, leading to dampness in your walls over time. Blocking the top prevents debris and animals from entering, but the chimney still needs air circulation to avoid condensation issues. Allowing the chimney to breathe maintains the health of your home and prevents long-term damage.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

This can add more protection from the heat and also protect the look of your hardscaping if you choose to remove the fire pit in the future.
