Single cast-iron door with heat-radiating 161 sq. in. ceramic glass view area, brick-lined firebox, and dual secondary air tube combustion system for longer and cleaner burns. EPA 2020 certified at [VERIFY: efficiency HHV — spec sheet i2450-2 shows 70.3%; Regency product website shows 67%; use confirmed certified value] and 1.6 g\/hr particulate emissions per certification label and manual. Up to 10-hour maximum burn, 75,000 BTU\/hr peak output, and a CSA B415-tested sustained output band of 12,900–30,000 BTU\/hr. Maximum log length 18 inches; fire builds directly on the firebrick floor — no grates per safety label. Requires an existing masonry fireplace with a minimum opening of 25\" W × 21½\" H × 17\" D and a new 5½\" or 6\" continuous stainless flex liner from the insert flue collar to the chimney top. Two buyer-configurable choices at order: faceplate size (Regular 40\"×30\" default, or Oversize\/Large 48\"×33\" for wider masonry surrounds) and door finish (Black default, or Black with Nickel Accent upgrade).\u003c\/p\u003e\n\n\u003cdetails open\u003e\n\u003csummary\u003eWho this is for\u003c\/summary\u003e\n\u003cdiv class=\"acc-body\"\u003e\n\n\u003ch3\u003eRight buyer\u003c\/h3\u003e\n\u003cp\u003eOwners of existing masonry fireplaces who want to convert an inefficient decorative hearth into a high-efficiency, EPA 2020-certified wood-burning heater — without demolishing and rebuilding the masonry structure. The i2450-2 slides into the existing masonry firebox opening, uses the existing chimney with a new stainless flex liner, and delivers serious supplemental or primary heat for medium-sized spaces. This is specifically a retrofit product: the masonry fireplace and chimney already exist; the insert transforms their function.\u003c\/p\u003e\n\n\u003cp\u003eBuyers whose existing masonry fireplace opening meets or exceeds the minimum required dimensions of 25\" wide, 21½\" high, and 17\" deep. Buyers whose masonry chimney is in sound condition — or can be made sound by a qualified mason before installation — and will accept a 5½\" or 6\" continuous stainless flex liner run from the insert flue collar to the chimney top. An inspection and cleaning of the existing chimney before installation is required, not optional. If the chimney has significant damage or an unconventional configuration, resolve it before purchasing the insert.\u003c\/p\u003e\n\n\u003cp\u003eBuyers who want two real design choices at order. Faceplate size: Regular (40\"×30\" default — covers the standard masonry surround for most fireplace openings) or Oversize\/Large (48\"×33\" upgrade — covers wider masonry surrounds where the Regular faceplate would leave exposed masonry visible around the edges). Door finish: Black (default — classic cast-iron stove aesthetic) or Black with Nickel Accent (upgrade — warmer metallic detail that reads as elevated in traditional and transitional interiors). Measure the existing masonry surround before ordering to determine which faceplate size achieves the intended coverage.\u003c\/p\u003e\n\n\u003cp\u003eBuyers in medium-sized spaces who want up to 10-hour burns from seasoned hardwood and a large, unobstructed view of the fire through the 161 sq. in. ceramic glass — a meaningful draw for buyers who want both heat and ambiance from the same appliance.\u003c\/p\u003e\n\n\u003cp\u003eBuyers who are comfortable with the operational model: air slide on the left side of the unit, doors operated fully open or fully closed during burning, fire built directly on the firebrick floor without grates, and a chimney that needs annual cleaning and inspection at least every two months during the heating season. The i2450-2 is not a set-and-forget appliance; it rewards attentive operation with long, clean burns.\u003c\/p\u003e\n\n\u003ch3\u003eWrong buyer\u003c\/h3\u003e\n\u003cp\u003eNot for owners of factory-built or zero-clearance fireplaces. The certification label states explicitly: \"INSTALL AND USE IN MASONRY FIREPLACE ONLY. NOT TO BE INSTALLED IN ANY FACTORY-BUILT FIREPLACE.\" A factory-built or prefab fireplace insert — even one physically similar in appearance — is a different, incompatible category requiring a unit listed for that specific application.\u003c\/p\u003e\n\n\u003cp\u003eNot for new-construction buyers who want a built-in fireplace but have no existing masonry shell to retrofit. New construction without a masonry fireplace already in place needs a zero-clearance (factory-built) wood fireplace installed in a framed chase — a fundamentally different product category.\u003c\/p\u003e\n\n\u003cp\u003eNot for buyers whose existing masonry fireplace opening is smaller than 25\" wide, 21½\" high, or 17\" deep. The insert physically cannot be installed in an undersized opening. Measure before purchasing — there is no workaround.\u003c\/p\u003e\n\n\u003cp\u003eNot for buyers who plan to use a grate, andirons, or any method to elevate the fuel off the firebox floor. The safety label explicitly prohibits grates: \"DO NOT USE GRATE OR ELEVATE FIRE. BUILD WOOD FIRE DIRECTLY ON HEARTH.\" The fire loads onto the firebrick floor only. Buyers who want elevated log sets as part of the aesthetic should look at gas insert options instead.\u003c\/p\u003e\n\n\u003cp\u003eNot for buyers who plan to skip the stainless flex liner. The liner is not optional — it is a required component per the certification (UL 1482-2022 \/ CAN\/ULC 628-2022). The insert cannot be safely or legally installed without a continuous liner running from the insert collar to the chimney top. Budget for the liner as part of the total project cost.\u003c\/p\u003e\n\n\u003cp\u003eNot for buyers expecting set-and-forget supplemental heat. Non-catalytic wood inserts require active operation: initial high-burn warm-up, air control adjustment, monitoring the draft, reloads every several hours. The 10-hour maximum burn is achievable on a full pack of dense seasoned hardwood with the air throttled back — but useful heat output over that cycle requires proper fuel and attentive air management.\u003c\/p\u003e\n\n\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eAt a glance\u003c\/summary\u003e\n\u003cdiv class=\"acc-body\"\u003e\n\n\u003cdiv class=\"spec-list\"\u003e\n\n\u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-label\"\u003eAppliance type\u003c\/div\u003e\n\u003cdiv class=\"spec-value\"\u003eNon-catalytic wood fireplace insert\u003c\/div\u003e\n\u003cdiv class=\"spec-meaning\"\u003eRetrofits into an existing masonry fireplace.

The figure that matters for daily planning is the sustained output across a full burn cycle, which the manual places in the 12,900–30,000 BTU\/hr band under test conditions. The Regency product page also cites 34,612 BTU\/hr as the EPA-tested output — this figure likely represents the average output during EPA crib-wood certification testing, which differs from the CSA B415-method cordwood range. The operative planning band is 12,900–30,000 BTU\/hr.\u003c\/p\u003e\n\n\u003cp\u003eA realistic operating day in primary-heat use for a medium-sized space: morning reload at cold start with the air fully open produces a 30–60 minute warm-up at high output as the insert and chimney come up to temperature; mid-session the air can be throttled back to sustain a medium burn; a full pack of dense hardwood at the end of the evening with the air gradually closed can provide up to the manufacturer-stated 10 hours of burn time, leaving a coal bed by morning. Actual burn duration varies by wood density, moisture, and air setting.\u003c\/p\u003e\n\n\u003cp\u003eThe 2.3 ft³ firebox sits in the medium insert tier. The 10-hour maximum burn time is genuinely achievable with the right fuel: dense hardwood, properly seasoned to 19%–25% moisture per the manual's seasoned cordwood specification, packed to the firebox capacity, air throttled hard at the close of the load cycle. Actual output and burn duration are highly sensitive to wood moisture — the same insert on properly seasoned wood versus marginally wet wood will perform completely differently on both metrics.\u003c\/p\u003e\n\n\u003cp\u003eThe dual secondary air tube system — what Regency calls \"dual-burn design\" — reignites combustion gases at the top of the firebox at operating temperatures. This secondary combustion is what enables longer, cleaner burns and lower particulate emissions at 1.6 g\/hr. Visible secondary flames (\"tubes flashing\") signal that the firebox is at proper operating temperature; the manual instructs operators to wait for this before closing the door fully on a new load.\u003c\/p\u003e\n\n\u003cp\u003eThe optional 2-speed blower materially improves heat distribution into the room. At low burn rates run the blower on low; at medium-high to high burn rates use the high setting. The heat-sensor thermodisc cycles the blower on automatically as the insert comes up to temperature — the manual recommends waiting at least 30 minutes after lighting before turning the blower on manually. Without the blower, heat distribution depends on convection from the grills and radiation from the glass door — adequate for supplemental heat in a single room, less effective for primary heat in larger or multi-room spaces.\u003c\/p\u003e\n\n\u003cp\u003eThe brick-lined firebox stores heat during active burning and releases it as the fire burns down — this thermal mass is part of what enables the long burn times and helps maintain useful heat output during the coast-down phase of the burn cycle. The same brick lining requires regular inspection and eventual replacement as a consumable; it is explicitly excluded from warranty coverage.\u003c\/p\u003e\n\n\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eTrade-offs to know\u003c\/summary\u003e\n\u003cdiv class=\"acc-body\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eMasonry fireplace is a hard prerequisite.\u003c\/strong\u003e This is not a product that can be adapted to a non-masonry installation.

Liner pricing varies by diameter, grade, length, and supplier; installation adds labor cost on top. For a two-story chimney the liner alone can add hundreds to over a thousand dollars to the project total, before installation labor. Budget for the liner as an unavoidable line item, not as an optional upgrade.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNo grates, ever.\u003c\/strong\u003e The safety label is unambiguous: fire must build directly on the firebrick floor. Buyers accustomed to log sets or raised grates from a previous decorative fireplace will need to adapt their expectations and operational habits. There is no workaround for this constraint — grates void the warranty and compromise safe operation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoors must be fully open or fully closed during burning.\u003c\/strong\u003e Partial-door operation is not permitted per the safety label: \"RISK OF SMOKE AND FLAME SPILLAGE, OPERATE ONLY WITH DOORS FULLY OPEN OR FULLY CLOSED.\" If the doors are left partly open, gas and flame may be drawn out of the opening. This rules out decorative fire-viewing with the doors cracked — doors are open only when reloading and closed the rest of the time.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFaceplate size selection is critical and permanent at order.\u003c\/strong\u003e The Regular (40\"×30\") and Oversize (48\"×33\") faceplates cover different widths of masonry surround. Measure the existing masonry surround — specifically how much width and height of exposed masonry you want the faceplate to cover — before ordering. Selecting the wrong size means either exposed masonry visible around the edges (Regular too small) or the faceplate overhanging the surround in an unsatisfactory way (Oversize too large for a narrow surround). This selection cannot be swapped in the field without purchasing the alternate kit.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExisting chimney condition is not optional to verify.\u003c\/strong\u003e The existing masonry chimney must be inspected and cleaned before installation. A chimney with deteriorated mortar joints, a damaged liner, or heavy creosote buildup is not a suitable host for this insert regardless of fireplace opening dimensions. The cost and complexity of needed chimney repairs should be factored into the total project budget before purchase.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFirebricks and gaskets are consumables excluded from warranty.\u003c\/strong\u003e The warranty explicitly excludes firebrick (rear, sides, or bottom), door and glass gasketing, and all baffles from coverage.

The source of this discrepancy is not confirmed — it may reflect a product revision, a test method difference, or a website data error.

On marginally seasoned wood or a cold start, effective output will land in the middle of the band. For buyers prioritizing maximum overnight burn times with minimum reloads, a catalytic insert at this firebox volume would extend the low-burn operating window.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBlower sold separately.\u003c\/strong\u003e The blower is not included with the insert — it is optional per the listing, but in practice it is a significant difference for buyers using the insert as primary heat.

Light the paper and kindling. Adjust the door opening initially to establish the fire and reduce smoke rollout; keep the door in this position for five to six minutes until the secondary air tubes start flashing, then close the door fully. Burn at high air setting (fully open) for approximately one hour to establish a solid coal bed before transitioning to the main load.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAir control.\u003c\/strong\u003e The draft control slide is located on the left side of the unit — slide left to open, right to close. The unit has a secondary draft system that continuously allows combustion air to the induction ports at the top of the firebox regardless of the primary control position. Open air = high fire; closed air = low fire. Adjust gradually from high to the desired position rather than jumping directly to low. Never reduce air aggressively before the fire is fully established.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoors — fully open or fully closed.\u003c\/strong\u003e Operate only with doors fully closed during normal burning. Open only for reloading, and open the air control fully for 10–15 seconds before slowly opening the door to equalize pressure and reduce smoke spillage. Never leave the door partially open during operation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFan operation.\u003c\/strong\u003e If the optional blower is installed, keep the switch in AUTO mode — the heat-sensor thermodisc cycles the fan on automatically when the insert reaches operating temperature, and shuts it off when the unit cools. Do not turn the blower on until at least 30 minutes after starting the fire. Run the fan at low speed for low to medium-low burn settings; at high speed for medium-high to high burn settings. Turn the fan OFF before opening the fuel door — the blower can push ash out of the firebox and into the room if left on during reloading. After the fire is out, the fan may continue running as the insert cools through the thermodisc cycle — this is normal behavior, not a defect.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eReload cadence.\u003c\/strong\u003e Once a solid coal bed is established from the startup and pre-burn loads, the main fuel load can be placed: up to 6 pieces maximum, 16.75\"–17\" long, 3\"–4\" diameter, loaded front-to-back (N–S orientation). Open air fully when reloading; once strong flames are established on the new load, adjust to the desired burn setting. For a high-output burn, keep air fully open. For a low overnight burn, reduce gradually to the low position after the load is engaged.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAsh removal.\u003c\/strong\u003e Remove ashes every few days during constant use. Turn the blower off before ash removal. Allow the firebox to cool. Place ashes in a metal container with a tight-fitting lid; store the closed container on a non-combustible floor outdoors, well away from combustibles, for at least 48 hours before disposal — hot embers can remain active for days. Take care not to let ash accumulate around the start-up air housing inside the firebox under the loading door lip.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGlass cleaning.\u003c\/strong\u003e The ceramic glass stays largely clear during proper hot burns with seasoned fuel. Tar or heavy black soot on the glass is a reliable indicator that the fire is running too cool or the wood is too wet. Wipe with damp newspaper dipped in cold ash, or use a dedicated ceramic-glass cleaner. Do not strike or slam the glass door shut — impact breakage is not covered under the thermal breakage warranty clause.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoor gasket maintenance.\u003c\/strong\u003e Test the door gasket with the paper-strip test: close the door on a strip of paper and try to pull it free; firm resistance means the gasket is sealing; easy pull means gasket replacement is needed. Door and glass gasketing are excluded from warranty coverage — plan on replacement every 2–4 seasons in regular use. The adjustable cam lock on the door compensates for gradual gasket compression over time; adjustment instructions are in the manual.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFirebrick inspection.\u003c\/strong\u003e Inspect the firebrick lining at least once per heating season. Cracks under approximately 1\/8\" are cosmetic and do not affect performance. Cracks wider than that, or bricks showing chunks missing, should be replaced. Firebricks are warranty-excluded consumables — replacement sets are available through Regency dealers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAnnual chimney sweep and liner inspection.\u003c\/strong\u003e During the first year of use, clean the chimney and liner twice; thereafter, clean at least once per year. During the heating season, inspect at least every two months for creosote buildup — if buildup reaches 3 mm (1\/8\"), sweep before continuing use regardless of how recently the last cleaning was done. A malfunctioning or poorly maintained chimney is a fire and CO hazard; do not defer this maintenance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWood seasoning.\u003c\/strong\u003e Hardwood needs a minimum of 12 months split, stacked off the ground with sun and wind exposure, to reach usable moisture levels; dense hardwoods like oak and maple may need 18–24 months. The manual specifies seasoned cordwood at 19%–25% moisture content; the startup load procedure calls for less than 20%. A digital moisture meter is the only reliable tool for confirming fuel readiness — do not trust supplier \"seasoned\" claims or visual inspection alone. Wood above 25% moisture will burn inefficiently, soot the glass, and accelerate creosote buildup in the chimney.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat never to burn.\u003c\/strong\u003e Per the manual: no treated wood, lawn clippings or yard waste, manure or animal remains, coal, rubber or plastic-containing materials, saltwater driftwood, garbage, cardboard, waste petroleum products (paints, thinners, asphalt), solvents, colored paper, Bio Bricks, construction or demolition debris, railroad ties, or unseasoned wood. Burning prohibited materials may release toxic fumes, render the insert ineffective, and void the warranty. Fire starters made from paper, cardboard, sawdust, or wax are permitted for the purpose of starting a fire only.\u003c\/p\u003e\n\n\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWarranty and service\u003c\/summary\u003e\n\u003cdiv class=\"acc-body\"\u003e\n\n\u003cp\u003eThe Regency Limited Lifetime Warranty for indoor wood products is extended to the original retail purchaser only and is non-transferable.
