Q: Are spider webs flammable?

• <div><p>Yes, spider webs are flammable, taking them from minor household nuisance to something more dangerous.

Q: What is the purpose of a spark arrestor?

• <div><p>A spark arrestor is a simple metal mesh device that prevents flammable particles from escaping from a combustion source and causing a fire. You typically find these attached to gas or diesel engines on things like cars, generators, and garden tools (lawnmowers, chainsaws, etc.).

Q: What is the best thing to put under a fire pit?

• <div><p>If you plan to put a fire pit on a grassy area, be sure to put compacted paver sand down first to help level out the ground and add better heat protection.

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.</p></div>

Q: What are the disadvantages of a ventless fireplace?

• <div><p>The primary disadvantage of a ventless fireplace is that it doesn&rsquo;t have an exterior venting system.
