Liner & Firebox

The category where PCE draws its hardest line: the high-consequence liner systems are install-only, because a relining job is a fire-safety system, not a box you fit on a Saturday. Alloy is the whole conversation — 316Ti for wood and high heat, 304 where the fuel allows. We supply the firebox repair components and accessory hardware, size every liner to the appliance listing, and install to UL 1777.

Anchor / installed

Cast-In-Place Liner Restoration (GoldenFlue / Supaflu-Style)

Cementitious cast-in-place system with form/bladder and mortar that rebuilds a deteriorated flue in place — restoring a smooth, insulated, code-rated passage inside the existing masonry. The premium answer for a historic or oversized flue where a stainless liner can't be sized in: done right, it's permanent and it strengthens the chimney. We never sell it as materials; it lives or dies on the install.

Method: Cast-in-place (cementitious)Store fit: Install-only, part of the reline job

Stainless Steel Flexible Liner Kit — Full (316Ti / 304)

Complete 316Ti or 304 stainless flex liner with cap, top plate, tee/connector, and clamps to reline a masonry flue for wood, gas, or oil. Alloy is the whole conversation — 316Ti for wood and high heat, 304 where the fuel allows — and we'll tell you which your appliance requires rather than sell the lighter grade to save a dollar. A Level-2 camera inspection comes first; we size the liner to the flue and the appliance, then insulate it. Supply-and-install only, because a flex liner kinked or under-clamped on a DIY pull is a flue fire waiting to happen.

Liner Insulation Blanket Wrap Kit (¼" / ½", UL 1777)

Ceramic/mineral blanket plus mesh and bands to wrap a stainless liner for clearance and draft per UL 1777. We treat insulation as standard, not optional — an insulated liner drafts hotter, keeps creosote down, and earns the clearance reduction the listing allows. Skipping it to save money is the false economy that brings you back for a draft complaint.

Refractory Firebox Panel Set (Prefab / Masonry Replacement)

Pre-cast refractory panels — OEM-matched for factory-built fireboxes — that replace cracked firebox walls and floor and restore the firebox's rating. Cracked refractory is a real safety item, not cosmetic: once the panel cracks through, the steel shell behind it is exposed to fire. We match the OEM panel to your firebox model; a generic panel that's close voids the listing.

Material: Pre-cast refractory (OEM-matched)Store fit: Measured + supplied + installed

Cast-Iron Throat Damper Assembly (Poker / Rotary Control)

Cast-iron throat damper plate and frame set at the firebox throat, with poker or rotary control. If your throat damper is rusted out, we'll often recommend pairing the repair with a top-sealing damper — the throat damper controls the burn, the top damper seals the idle flue. We size the plate to the throat so it actually closes square.

Liner Connection & Termination Hardware (Tee, Top Plate, Connector)

The stainless hardware that turns a length of liner into a finished, code-correct system: the bottom tee and removable snout that connect to the appliance, the top plate and storm collar that seal and anchor the liner at the crown, and the connector that ties it to the stove or insert. We don't sell these as a parts pile — they're matched to the liner diameter and the appliance collar, because a loose tee or an unsealed top plate is exactly where a reline leaks combustion gas or rain. Supplied and fitted with the reline.

Alloy: 304 / 316 stainlessStore fit: Matched to liner + appliance, installed

Code part / accessory

Smoke Guard / Adjustable Fireplace Hood

Adjustable stainless or black-steel band mounted across the top of the fireplace opening to stop smoke rolling out into the room — the fix when the opening is too tall for the flue it's paired with. It corrects the opening-to-flue ratio mechanically by shrinking the opening just enough, and we set it to the smallest reduction that actually stops the roll-out so it stays nearly invisible. We diagnose why the fireplace smokes first; a guard is the right answer to a ratio problem, not to a blocked or undersized flue.

Firebrick / Refractory Split-Brick Set

Boxed rated firebricks for rebuilding or patching a masonry firebox floor and walls — sold as the correct rated firebrick for the heat, not common brick, which spalls. A capable homeowner can patch a single course; a failing back wall is our rebuild.

Material: Rated firebrickStore fit: Ships boxed; install offered

Code part / accessory

Cast-Iron Fireback

Decorative cast plate that stands at the back of the firebox to radiate heat forward and shield the masonry — the rare product that's both protective and beautiful. It pushes heat into the room and saves the back wall from the fire: a genuine craftsmanship accent for a working hearth.

Material: Cast ironStore fit: Ships boxed

Code part / accessory

Chimney Cleanout / Ash-Pit Door (Steel / Cast-Iron, Framed)

Lockable framed access door at the chimney base for clearing the ash pit and sweeping debris — a small part that matters. A sound, gasketed cleanout door keeps the draft right and the basement clean; we cut it into the masonry square so it seals, because a rattling door is an air leak.

Material: Steel / cast ironStore fit: Ships boxed; masonry cut-in offered
