Whitfield Advantage Replacement Set
This aftermarket set contains three fire bricks and is listed for Whitfield Advantage II-T and Advantage III pellet stoves with serial numbers 18145 and up. The product information specifies a 12 3/4-inch center brick height and identifies the set as made in the USA.
Best for: Owners of the listed Whitfield models whose stove serial number and existing center brick measurement match. It was selected because the listing names specific stove models and gives a measurement to check before purchase.
Check before ordering: Measure the center brick and confirm the serial number. Avoid choosing this set based on the Whitfield name alone; the listing’s model and serial details are specific.
Ashley AP5660L Three-Piece Set
This complete three-piece firebrick set is listed as compatible with the Ashley AP5660L and Ashley AP5660PE. Its stated fit information makes it a direct model-specific option for owners of either listed stove.
Best for: Ashley AP5660L or AP5660PE owners who need the listed complete set rather than a single brick. It was selected because the product is specifically identified for two Ashley pellet stove models.
Check before ordering: Confirm the full model designation on the stove. The available product details do not provide individual brick dimensions, so compare the existing layout or verify the part reference if your stove has a different suffix or configuration.
Englander CPM Fiberboard Firebrick
Lynn Manufacturing’s replacement fiberboard firebrick is identified as part 2408A. It replaces Englander, Summers Heat, and Timber Ridge CPM-CFB or PP1022 references. The stated fit includes Englander pellet stove models with CPM in the model designation, including 10-CPM, 49-SHCPM, and 49-TRCPM. The listed size is 17 by 9 3/4 by 1/2 inches.
Best for: Owners of the listed CPM-family stoves who need a single large fiberboard panel. The model references and dimensions make this choice easier to compare with an existing panel than a generic brick listing.
Check before ordering: This is a fiberboard panel, not a three-piece brick kit. Confirm the stove model and the 17-by-9 3/4-inch panel dimensions before selecting it.
Englander 10-CDV Ceramic Fiber Board
This Stove Parts 4 Less replacement ceramic fiber board is listed for the Englander 10-CDV. The product information identifies it as a replacement for part numbers CU-CFB and 22482, and gives a width of 14 1/8 inches and a height of 9 inches.
Best for: Owners of an Englander 10-CDV who need the board associated with either listed part number. It was selected as a distinct Englander option because it covers a different model and part reference from the CPM fiberboard above.
Check before ordering: The supplied dimensions cover width and height but do not state thickness. Verify the part number and compare the board’s shape and measurements with the part in your stove.
US Stove Bay Front 5660 Set
This complete three-piece firebrick set is listed as compatible with US Stove Company models 5560 and 5660. The seller information also states that it is a USA-based seller with customer support.
Best for: Owners of the US Stove 5560 or 5660 who are replacing the complete three-piece firebrick set. It was selected because it identifies both stove models and supplies a set rather than a loose, unspecified brick.
Check before ordering: Confirm whether the stove is a 5560 or 5660 and compare the existing arrangement. The provided features do not include brick measurements, so do not assume the set fits other US Stove models.
Buying Guide: How To Choose Pellet Stove Fire Brick
How do I find the correct part for my stove?
Start with the stove’s manufacturer name and complete model number. Look for the identification plate or label on the appliance, then compare that information with the replacement listing. Similar-looking stoves can use different firebox panels, brick counts, or dimensions. A product described for one model family should not be treated as universal unless the listing explicitly says so.
For a model-specific replacement, check any listed part number and serial-number range as well. For example, the Whitfield set has a stated serial cutoff, while the Englander board listings identify model families or replacement part references. Use all available identifiers rather than relying on brand alone.
Should I buy a complete set or one board?
Choose a complete set when multiple bricks need replacement or when the listing matches the full firebox arrangement. The Ashley and Bay Front products are described as three-piece sets. A single fiberboard panel may be more appropriate when only a large panel is being replaced and the stove model and dimensions match, as with the Englander CPM and 10-CDV listings.
Check what the product actually includes. “Firebrick” can refer to individual blocks, a shaped panel, or a multi-piece kit. Compare the number of pieces and the outline of each part with what is installed in your stove before ordering.
What measurements should I compare?
Measure the old part when it is safe to access and the stove is cool. Record height, width, and thickness where applicable. Also note whether the panel has cutouts, angled edges, or a particular orientation. A matching length and width alone may not establish a fit if the shape or thickness differs.
Use product measurements as a screening check, not as a substitute for confirming the model. The Whitfield product specifically calls for checking center brick height. The Englander CPM listing supplies three dimensions, while the 10-CDV listing gives width and height but not thickness.
Are generic wood-stove bricks suitable for a pellet stove?
Do not assume that a brick marketed for wood stoves or fireplaces is suitable for a pellet stove. Pellet appliances may use model-specific firebox parts, including shaped bricks or fiberboard panels. A generic brick could differ in size, thickness, material, or arrangement. Choose a general-purpose product only when the stove documentation or a qualified service professional confirms that its specifications are appropriate.
What material is right: brick or fiberboard?
Follow the part type specified for your stove. The products in this comparison include multi-piece firebrick sets and replacement fiberboard panels. These product descriptions do not establish that the materials are interchangeable. Replacing a board with a different material or changing the firebox layout without confirmation can result in an improper fit.
If the original part’s material is unclear, consult the stove manual, the manufacturer’s parts information, or a qualified stove technician. Do not modify a replacement to force it into place unless the appliance instructions specifically permit that work.
When should I replace a firebrick?
Inspect the firebox during routine maintenance, following the stove manual’s instructions. Cracking, crumbling, missing sections, or a part that no longer stays in its intended position can indicate that it needs attention. The product details provided here do not specify replacement intervals, so use the appliance maker’s guidance rather than a general schedule.
Allow the stove to cool completely before inspecting or measuring its interior. If damage is extensive or you are unsure whether the firebox is safe to operate, stop using the appliance and seek guidance from the manufacturer or a qualified service professional.
Frequently Asked Questions
Can I use any fire brick in a pellet stove?
No. Pellet stove fire bricks and panels can be model-specific. Match the replacement to the stove model, part reference, dimensions, material, and shape before buying.
How do I know whether a Whitfield set fits my stove?
Check that the stove is an Advantage II-T or Advantage III with a serial number of 18145 or higher, then measure the center brick height. The listing specifies 12 3/4 inches for that measurement.
Are the Englander CPM and 10-CDV boards interchangeable?
The product details identify them for different Englander model groups and give different dimensions or part references. Do not treat them as interchangeable; match the board to the stove model and existing part number.
Does the Ashley set fit every Ashley pellet stove?
The listed compatibility is limited to the Ashley AP5660L and AP5660PE. Confirm the exact model before ordering rather than assuming it fits other Ashley stoves.
What should I do if the model number is unreadable?
Check the owner’s manual, purchase records, or the manufacturer’s parts information for the stove’s model and serial details. If you cannot verify the correct replacement, ask the manufacturer or a qualified service professional before buying.
