How to Draw Fireplace Box Plans

If you lot want to make your dream of owning a real fireplace a reality, you accept 3 choices: a gas burning fireplace, a masonry fireplace, or a prefabricated metallic wood burning fireplace.

If metal fireboxes or gas fireboxes don't suit your fancy, this page is for you lot. Below, I'll outline the necessary steps needed to build a masonry fireplace.

We build masonry fireplaces using fire resistant bricks, fire resistant mortar, and other concrete masonry materials. The success of your DIY masonry fireplace project depends on having the correct tools, doing the appropriate prep work, and knowing the proper construction steps.

How to build a masonry firebox?

Masonry fireplaces are heavier than their mod prefabricated metal counterparts. For this reason, you lot should cascade a proper footing underneath the fireplace. This concrete basis has to be reinforced to concur the extra weight and ought to exist about 8" larger on each sides of the fireplace. The depth depends on the weight of the chimney, CMU shell, firebox, and hearth.

For proper depth and reinforcing requirements, you might need to consult an engineer or an experienced fireplace contractor who can help you lot edifice a long lasting masonry fireplace.

Many indoor masonry fireplaces are elevated off the floor. In that case, you might want to lay i or two courses of concrete blocks on your concrete floor to drag the floor of your masonry firebox. The CMU block is eight" in meridian. It is common to employ a "half loftier" (4") to get to the 10-inch superlative. Proceed in heed — the commencement grade of your firebrick on the floor of the masonry box is around two ½" with a light mortar bed. This could be an of import elevation if you are building a fireplace hearth on the front of the firebox since you volition need to find a material that meets the elevation of the firebox floor (I'll explain that in detail later in this article).

If you are building an outdoor masonry fireplace, the process is the same.

Laying your firebricks

The flooring of your masonry fireplace is the easy office. We usually install firebricks in running bond pattern. Y'all volition demand to cutting your firebricks in half with a hammer or a wet saw. If you lot divide the one-half firebricks with a hammer, you lot will have to make sure that the cutting sides are running exterior of, or are hidden underneath of, the firebox walls.

At this point, I need to mention the importance of having fire resistant mortar for whatever area the burn down could potentially reach (in the firebox).Therefore, I personally utilise fireclay for all of my fire resistant mortars. I mix sand, Portland cement, and fireclay at a 3:i:ane ratio and mix information technology to a peanut butter consistency. That's 3 parts sand, i function fireclay, and 1 part Portland cement. Using fireclay is cheaper than premixed burn resistant mortar products.

Afterwards that, apply a level and gently tap the firebricks onto your mortar bed to level them out. Then, lay your firebricks in a tight joint bed. This pleases the center and ensures the fire won't erode the mortar over time. And then, use a sponge to polish the mortar onto the joints — much like when you lot are grouting ordinary tiles. The size of your fire bricks s are 9"x four"x ii ¼".

Building the side walls of the firebox

Earlier y'all lay your firebox walls, you'll need to make up one's mind the width and depth of your firebox. This can be washed by marking the metal damper on the bottom of the floor. Pencil-mark the outlines and make certain that the side walls of your firebox back up (embrace) the lines.

Now, this role is somewhat difficult. You should cobble back the dorsum wall of the masonry firebox to encounter the outside rim of the cast iron damper. To do this, you'll need to tilt each row of firebricks until the last row reaches the outside of the metal damper. Then, once finished, you should have reached the lesser part of the chimney.

The tilted dorsum office volition enable your fireplace depict fume efficiently.

This invention is credited to the one-time Rumford fireplaces.

If you're not using a cast metal damper, you'll need to lay an angle iron on the front of the firebox walls. This holds the chimney and enables yous to build your kickoff course on the peak of information technology. On outdoor masonry fireplaces, it's not necessary to employ a fireplace damper.

Yet, you'll still demand to cobble dorsum the size of your firebox to reach the intended size of your chimney. This is shown in the picture on the left. Simply stride each brick dorsum near an inch until the size of the brick chimney corresponds with the size you intended information technology to have.

And so, afterwards reaching the intended width, you accept two options for the chimney flue — you can either apply a traditional clay piping or opt for a more modern steel flue.
