A dark line where the floor meets the walls

The joint where the firebox floor meets the back and side walls takes heat from the fire and ash sitting against it. When that joint opens, it shows as a dark gap running along the base of the walls, sometimes with loose grit in it.

We probe that joint along its whole length, rake out what has failed and repoint it in refractory mortar. While we are down at floor level, the floor firebricks get checked for cracks and rocking as well. A gap along the base of the firebox walls in Penney Farms? Call (904) 920-5495 and we will measure it.

Doors, inlets and firebox heat in Penney Farms

Some Penney Farms fireplaces have doors or an outside air inlet. Run hard, either can raise the firebox temperature, which the Brick Industry Association links to early breakdown of mortar joints.

When joints wear fast, we look at how the fireplace is used as well as at the brick.

The eight-inch and ten-inch firebox walls

Section R1001.5 sets the firebox walls by thickness. Where the firebrick lining is 2 inches thick or more, the back and side walls must be at least 8 inches of solid masonry counting the lining. Without a lining, the walls need 10 inches of solid masonry.

A lining worn thin is therefore more than a cosmetic problem, because the credit for the lining depends on its thickness. When we assess a worn wall, we compare what remains with those figures and write down whether new firebrick restores the wall or whether the backing masonry needs attention as well. That comparison is on the estimate in plain numbers.

The throat above the opening

Above the firebox, smoke passes through a slot called the throat into the smoke chamber. The Florida code places the throat at least 8 inches above the fireplace opening, calls for it to be at least 4 inches deep, and does not allow the passage above the firebox to be smaller than the flue.

A firebox repair seldom reaches the throat, but a rebuild of the upper back wall does. We measure the throat before any brick comes out of that area and rebuild to the same or better dimensions, so the repair does not create a smoke problem that was not there before. The measurements go on the ticket.

Clearances when a rebuild opens the wall

A full firebox rebuild can expose the framing around the fireplace. Section R1001.11 requires wood beams, joists, studs and other combustibles to stay at least 2 inches from the front faces and sides of a masonry fireplace and 4 inches from the back faces.

When a rebuild opens the masonry far enough to see those distances, we check them and write down what we found. Framing closer than the code allows goes on the estimate as a separate item, since it has to be corrected before the fireplace is used again. A lining repair alone does not open the wall that far.

Firebox repair questions from Penney Farms

How long before we can use the fireplace after a firebox repair?

That depends on the mortar. One medium-duty refractory mortar needs at least 7 to 10 days before heat, and we write the exact date on the ticket. The first fire after that should be small.

Should I stop using the fireplace until the repair?

If bricks are loose, joints are open deep into the wall or the back wall bows, yes. Hairline cracks in sound brick can wait for the visit, and we tell you which you have. Call (904) 920-5495 to book a free inspection in Penney Farms.
