Gas Fireplace Hearth Requirements of a fireplace hearth

A hearth is the part of your home that surrounds your fireplace. It needs to be constructed on sound material, and must be sturdy enough to support heavy objects like firewood or even people getting too close to the heat source. The primary purpose of a hearth is not only protection from hot embers but also to add a decorative element.

The following explanation will help you understand the necessary requirements of your hearth:


Your fireplace hearth must be made from granite, tile or brick––as these materials are durable and easier to clean than other options. Granite is very sturdy and can withstand heat while looking great in any room that is decorated with a stone fireplace. Tile is an economical option and can be found in nearly any color, size or shape to coordinate with your decor.

Bricked fireplaces tend to look elegant and add warmth, but they may need more maintenance than other types of hearth material because bricks are porous and will absorb soot over time––meaning you’ll need to repaint them periodically.

Decorative Elements

Your hearth does more than just keep you safe from the heat of your fireplace––it also adds an element of design and warmth to any room that is decorated with a stone or brick fireplace. You can use your new hearth as part of your home décor by adding some interesting elements. For example, you could add a white brick hearth with some colorful flowers in the front. You can also incorporate your fireplace into your décor by painting it to match or complement your walls so that they flow together nicely when viewed from across the room.

Building Your Hearth

The most important thing about building an effective hearth is to make sure you build it strong enough to withstand the heat and weight of your fireplace. You must also construct a hearth that is large enough so that people can stand next to the fire without feeling too hot or getting burned if they touch something inside their fireplace––and don’t forget about how many logs will fit in there as well!

You can build your hearth yourself, but it is recommended that you have a professional do the job to ensure everything comes together properly.

Ensure that the gas fireplace is on a nonflammable surface. Do not use it on an unstable or wooden table, as this can cause damage to both the floor and your fire place. Make sure there’s nothing flammable within three feet of the unit before using it for any extended period of time.

Ensure that you’re wearing nonflammable clothing while using the unit. If your clothes catch aflame, stop using it and help put out any fires before they get worse.gas fireplace

How to install your own Gas Fireplace Hearth?

The first step to installing your gas fireplace hearth is making sure there’s a proper foundation. Once you have done that, it becomes much easier for you to install the firebox and gas lines. For this type of installation, we recommend hiring a professional installer as they are more familiar with safety codes and procedures involved in these types of installations.

There may be a gap between the floor and your gas fireplace hearth which can lead to potential problems down the line, so you should check first if there is enough space for it to sit flush with the rest of the flooring. You will need this gap as part of installation process or else firebox won’t fit properly.

Tips on picking out the right style and size of your new gas Fireplace Hearths

Take measurements of the hearth area in order to get an accurate picture of what size is best for your home. Keep in mind that actual dimensions may vary slightly from published ones, depending on construction differences between manufacturers.

  • Before you shop: Measure and sketch or measure photos/pictures for reference materials.
  • At the store: Examine the hearth for any damage or warping, and check that it fits flat against a wall. Look inside to see if there’s an adjustable flame effect with no visible wire connections.
  • Consider purchasing from a licensed contractor so you can be sure of installation practices as well as warranty coverage.

Ask a sales associate about the following:

  • Warranty information, including length of coverage and what is covered.
  • Installation instructions for building on/building out (if needed) to accommodate your home’s structure, such as insulation or horizontal support beams in some cases.
  • If there are any concerns with installation that the sales associate is unable to answer, contact the Hearth manufacturer directly.
  • Be sure your new gas Fireplace Hearths are installed by a licensed contractor with state and local permits for installing hearth products.
  • Ask manufacturers what you should do if there aren’t any existing clearance or support beams in place before installation begins. There are several options to consider, but your Hearth manufacturer should be able to help you find the best solution.
  • Once installation is complete, have a fire safety inspector meet with or visit you at home before using gas Fireplace Hearths for the first time.

Environmental Protection Agency Requirements

The fireplace must have a minimum efficiency of 78% AFUE if approved for installation in a mobile home. This is the measure of how much fuel you use to heat your home versus the amount that escapes up the chimney or venting system. The EPA also requires an annual inspection by a certified gas inspector, and full disclosure at your closing of the home sale – on a mobile home, it is not considered a permanent fixture and therefore must be removed.

A fireplace can save you money during those cold winter days if properly used as your main source of heating in place of running that furnace or electric baseboard heaters all day long. A gas stove will also help to reduce your heating bill. The best way to use your stove is during the hours of peak energy usage which are typically in the morning and early evening when everyone turns on their heaters just before leaving for work or school, then turn them off again until it’s time to head home.

This can help you save up to 30% per year depending on how much you use your fireplace during the winter months.gas fireplace

Safety Tips

  • Keep an open flame away from children and pets.
  • Have a fire extinguisher on hand just in case of emergencies.
  • Only use a gas fireplace for its intended purpose.
  • Keep a clear space surrounding the fireplace at least 36 inches wide. Any combustible objects should be kept out of this area too. Keep curtains and other flammable items away from your fireplace as well.
  • Make sure to always have proper ventilation when using a gas fireplace in order for carbon monoxide to escape properly. If you don’t have a way to ventilate the area, you should not be using your fireplace.
  • Do not block any of the heating vents on a gas fireplace because this will prevent proper circulation and ventilation from occurring.
  • Keep all flammable objects away from furniture in front or next to your fireplace where they could get too close and ignite.
  • Do not use an extension cord with a gas fireplace because doing so can cause problems like overheating, which could lead to fires or damage to the wiring of your appliance.
  • If you smell any unusual odors when using your gas fireplace or hear strange noises coming from it, turn it off immediately and contact a gas fireplace technician.
  • When using your gas fireplace, always read the instructions thoroughly and make sure you know how to use it properly before turning on any of its controls.
  • Make sure there is nothing in front or next to your fireplace that could catch fire when you are burning something inside of it.
  • Keep any combustible objects away from your fireplace when it is burning.
  • Make sure the area directly around your gas fireplace is clear of any flammable items or materials, such as curtains and other fabrics that could catch fire if they came into contact with a flame for too long.
  • Place furniture far enough away from your fireplace so that it cannot catch fire or become a fire hazard.
  • Keep all combustible objects away from your gas fireplace when it is in use.
  • Make sure nothing flammable is stored underneath your fireplace, otherwise there could be a risk of the object catching on fire and creating an even bigger problem that will lead to accidents.
