Delayed gas ignition: An explosive problem. If the banging noise is located at the heater this is most likely the problem. Delayed gas ignition is when gas in the furnace builds up rather than igniting immediately. When the gas finally ignites after building up a while, a mini explosion happens—possibly harming your furnace. Causes of delayed
We have written a lot of articles lately on how to troubleshoot problems with your furnace, but today's topic is a bit more serious. When someone asks us why their furnace smells like gas, the answer is almost always due to a leak in your furnace's heat exchanger, which can be serious for all sorts of reasons including possible fire hazards, explosions and carbon monoxide poisoning.

Blast furnaces are similar to furnaces, but can smelt only ore blocks and tools/armor made of iron, gold or chainmail. Smelting equipment yields one iron or gold nugget from their respective materials. Once an item and a fuel are placed into the blast furnace, the block state changes to lit and the item is smelted twice as fast as a regular furnace. Fuel is also used at double the rate of
