Wood stove hearth pad requirements

You may be thinking why do I need a wood stove hearth pad, well fire codes state that one is needed over any combustible surface, like wood floors for example, and really most people have one under their stove but some questions we will answer during this post are, do I have the right hearth pad for my stove size and is it made of the right materials to be code compliant.

If wood stove floor protection is not coded compliant it could void your fire insurance at the time of a claim, no one wants that, also having the right size and proper hearth pad materials make your wood-burning stove safer for your family.

Wood burning appliance test standards started in the 1970s and have evolved drastically since then, and modern-day stoves are very safe to use when installed correctly.

Floor pads have been an important part of that testing over the years, to know what to expect for clearances to combustibles with your wood-burning stove you should first take a look at the certification label on the back of it.

Generally, to find it you just need to look for a label that is usually black with gold or silver lettering and you will see indications on it that show the clearances to combustibles, you should always use these clearances because your wood stove was tested in accordance to them.

Also, the clearances for distances to a wall or anything combustible like a ceiling are also on your stove label and in your user manual and they are different from the standard wood stove hearth pad requirements.

Pay attention to your wood stove certification label

As a disclaimer always follow the indications for clearances to combustibles specified on your wood stove certification label or owner’s manual, if your wood stove doesn’t have a label it will be considered an uncertified appliance, and your wood stove floor pad clearances change considerably.

How to size your hearth pad

These are standard measurements according to the W.E.T.T certification (standard in Canada)

and the NFI National Fire Institute being the (standard in the USA)

As a disclaimer, make sure you always do your own investigating on these authority websites that set the standards, and always take into consideration what your wood-burning appliance owner’s manual says because every stove is different in size and specs.

So with that said let’s take a look at some information and ideas so you can decide what you need for floor protection under your wood stove.

Regular wood stove hearth pad size

Remember these measurements are only showing you how much space your minimum floor protection needs to be, note that this can be larger than what is shown in the diagrams, and remember this is not showing clearances to a combustible wall or ceiling it is only showing where to situate a wood-burning stove on floor protection.

Regular hearth pad size

The standard distance extended from the back of the wood-burning appliance is 8″.

The standard distance extended from the sides of the wood-burning appliance is 8″.

The standard distance extended out of the front of the wood-burning appliance is 18″.

This distance is larger because the front of the stove is where the doors open and hot coals need an ember pad to fall onto.

With a side door

The standard distance extended from the back of the wood-burning appliance is 8″.

The standard distance extended from the sides of the wood-burning appliance is 8″.

The standard distance extended out of the front of the wood-burning appliance is 18″.

Now if you have a side door or second door you also need to leave an 18″ distance for your hearth pad on that side also.

Corner installation

The standard distance extended from the back of the wood-burning appliance is 8″.

The standard distance extended from the back corners of the wood stove to the edge of the sidewall of the hearth pad needs to be 8″.

The standard distance extended out of the front of the wood-burning appliance is 18″.

This distance is larger because the front of the stove is where the doors open and hot coals need an ember pad to fall onto.

Now if you have a side door or second door you also need to leave an 18″ distance for your hearth pad on that side also.

It’s important to note that these measurements can sometimes be slightly different on the certification label of your wood-burning stove, some may say 8″ on the sides and 16″ on the front or side door, generally being the standard in the USA.

How thick does a hearth pad need to be?

The standard for a hearth pad thickness is a minimum of 3/8″ or 8mm, and this can be thicker depending on the noncombustible material used, something that is important and not always stated on stove labels is that the hearth pad should be a continuous surface.

If your wood stove manual requires type 2 ember protection for your hearth pad and you need to calculate your hearth pad R-Values then take a look at my post HOW TO CALCULATE WOOD STOVE HEARTH PAD R VALUES

Floor protection continuous surface

You may be asking why should wood stove floor protection be a continuous surface. well the answer is simple, think about a hearth pad made of bricks or ceramic tiles, if they are laid directly on a combustible wood floor for example there will be gaps between each brick or tile and if by chance an ember falls out onto the floor and between those cracks you could have a serious fire on your hands, you may not even notice that an ember fill out and it could smolder there for hours or even days till it catches fire.

The solution is always a continuous surface like a piece of sheet metal or cement board below the tile or brick that has gaps

Under your hearth pad

You will need protection under any materials that have gaps like tiles, bricks, or anything that is not a continuous surface as I have mentioned above, so under any of these materials you need a continuous piece of metal or cement board that is the total dimensions of your calculated hearth pad size, this is to prevent any embers from falling between the cracks or gaps possibly causing a fire, and this also makes the surface ridged and stronger.

This is a useful point if you are building your own DIY hearth pad, but if you buy one pre-made from a manufacturer you don’t need to worry about this because it will be built to code.

Hearth pad trim

Some people call this a wood stove ember pad and the name makes sense because the reasoning behind it is to stop embers from falling on your wood floor and so on, and some people ask if this is an ember pad can I use a wood trim around the outside edge to finish it, and the answer is yes you can as long as you are 18″ distance from the front or any secondary door, and 8 on each side and back, but id you van finish yours with a metal edge it can be a little safer, and most store-bought ember pads or hearth pads come with a finished metal edge.
