Fireplace Refractory Panel Replacement in Spring Hill, FL

What Fireplace Refractory Panels Do

Fireplace refractory panels are the molded heat-resistant slabs that line the inside of a factory-built firebox. They take the heat of the fire and keep it off the metal box behind them. One maker's wood fireplace manual describes a refractory hearth, sides and back, reinforced with steel, held in place by retaining brackets and a grate.

The same manual says plainly how they fail: the refractories can be broken by improper use, and dropping logs on the bottom panel or building fires right against the panels can cause premature burnout. It also says they may easily be replaced.

Hairline Crack or Through-Crack

Not every crack means a new panel. Fine hairline cracks can appear on refractory as it heats and cools, and that maker treats them separately: its warranty terms exclude hairline cracks in refractory. A hairline crack in a panel that is still flat, tight in its retainers and not missing any material is noted and watched.

A through-crack is different. When a crack runs all the way through a panel, when a piece has broken out, when the face crumbles or when metal shows through, the panel is no longer doing its job of shielding the box. That panel is replaced. We will not give you a crack width rule of thumb, because the maker's manual we read gives none; the decision is made panel by panel, with the panel in hand.

Replacement Panels by Model

Panels are shaped for one firebox. Their size, the angle of the sides, the pattern that lines up from panel to panel and the cut-outs for gas line knockouts or grate retainers all belong to a model. Section R1004.1 of the Florida Building Code, Residential, says a factory-built fireplace is installed to the conditions of its listing, and its panels are part of what was tested under UL 127.

So fireplace panel replacement starts at the label, inside the opening or behind the lower grille, which names the maker and model. From that we order the panels made for your unit. Generic boards cut to fit are not the same thing, and we do not claim they suit every fireplace.

When the Panels Are No Longer Made

Units of the 1980s, 1990s and 2000s outlive some of their parts. When the maker, or the company that took over its line, no longer supplies panels for a model, we look for the replacement the maker itself names for that model. If there is none, there is no listed panel to fit, and the honest choices are to stop burning in that fireplace or replace it. We quote fireplace replacement alongside in that case, so you can compare.

How the New Panels Go In

The grate, screen and hardware come out first. The old panels are lifted out and the box behind them is checked for rust or burn-through. The new set goes in the order the maker gives: in that maker's manual, the rear panel first, its pattern lined up with the sides, then the retaining bracket and set screws; the side panels next, with their gas line knockouts facing down; and the hearth panel last, flush with the front. The grate and screens go back on before the first fire.

Firebrick in a masonry fireplace is a different job, laid in refractory mortar as section R1001.5 of the code describes, and it is covered by firebox repair.

The inspection is free and starts with the label. Your estimate, in writing, names the panels for your model or explains why none exist. Local, family-owned and Proudly American, we send an experienced crew that fits panels in the maker's order.
